Computing polygenic risk scores (PRS) to predict the degree of risk for obesity may contribute to weight management programs strategically.. To investigate the combined effect of FTO rs9930501, rs9930506, and rs9932754 and ADRB2 rs1042713 and rs1042714 using PRS on (1) the odds of obesity and (2) post-intervention differences in dietary, anthropometric, and cardiometabolic parameters in response to high-protein calorie-restricted, high-vitamin E, high-fiber (Hipcref) diet intervention in Malaysian adults.. Both a cross-sectional study (n = 178) and a randomized controlled trial (RCT) (n = 128) were conducted to test the aforementioned objectives. PRS was computed as the weighted sum of the risk alleles possessed by each individual participant. Participants were stratified into first (PRS 0-0.64), second (PRS 0.65-3.59), and third (PRS 3.60-8.18) tertiles.. The third tertile of PRS was associated with significantly higher odds of obesity: 2.29 (95% CI = 1.11-4.72, adjusted p = 0.025) compared to the first tertile. Indians (3.9 ± 0.3) had significantly higher PRS compared to Chinese (2.1 ± 0.4) (p = 0.010). In the RCT, a greater reduction in high-sensitivity C-reactive protein (hsCRP) levels was found in second and third tertiles after Hipcref diet intervention compared to the control diet (p interaction = 0.048).. Higher PRS was significantly associated with increased odds of obesity. Individuals with higher PRS had a significantly greater reduction in hsCRP levels after Hipcref diet compared to the control diet.

The aim of this study was to investigate the effectiveness of the Hipcref (high-protein, energy-restricted, high-vitamin E and high-fibre) diet in Malaysian adults on body composition and metabolic parameters after an intervention period of 6 months. Overweight/obese Malaysian adults (n 128; BMI≥23 kg/m2) were randomised to the Hipcref (n 65) or control diet (n 63). The intervention group received Hipcref diet charts based on their personal preferences. The control group followed a generalised dietary advice based on Malaysian Dietary Guidelines, 2010. All participants were responsible for preparing their own meals. There was a significant treatment group×time effect on anthropometric parameters (P<0·05) on an intention-to-treat basis. Pairwise comparisons revealed that Hipcref diet participants had significant reduction in weight, BMI, waist circumference, fat mass and percentage body fat at months 3 and 6 compared with baseline (P<0·001). The control group had significant increase in weight and BMI at months 3 and 6 compared with baseline (P<0·05). The Hipcref diet group had higher reduction in fasting insulin, insulin resistance and C-reactive protein levels compared with the control group at month 6 (P<0·05). Post-intervention, compared with the control group, the Hipcref diet group was found to consume significantly higher percentage energy from protein, and PUFA, higher energy-adjusted vitamin E (mg) and fibre (g), and lower total energy, lower percentage energy from fat and carbohydrate (P<0·05). The success of the Hipcref diet on overweight/obese Malaysian adults may be due to the combined effect of the nutrient composition of the Hipcref diet.

Social media may be an effective medium by which parents could be trained to promote healthy eating behaviour and physical activity for their children. This trial evaluates the effectiveness of a family-based intervention using social media in combination with face-to-face sessions - the REDUCE (REorganise Diet, Unnecessary sCreen time and Exercise) programme - on adiposity of Malay children.. Five primary schools in an urban area in Selangor, Malaysia participated in this two-arm randomized controlled field trial. Participants were parents (n = 134) and their primary school-going children 8-11 years of age who were either overweight or obese. These parent-child dyads were randomly allocated to intervention and wait-list control groups and were blinded to group assignment. The intervention was a four-week training programme using two face-to-face sessions and two Facebook sessions followed by weekly booster sessions over a three-month period using WhatsApp. The primary outcome was body mass index (BMI) z-score. Height, body weight, waist circumference and percentage of body fat were measured by blinded assessors. Data were collected at baseline (T1), immediately post-training (T2) and at three- (T3) and six-month post training (T4) and were analysed using generalized linear mixed modelling adjusted for covariates to estimate the intervention effects. Subgroup analysis was conducted for overweight and obese children.. Ninety-one percent of parents completed the study, 64 in intervention group and 58 in wait-list group. At the sixth month post-training, BMI z-scores were significantly reduced in the intervention group compared to the wait-list group, for the all children (overweight and obese children) and within the obese subgroup ((F(6, 517) = 2.817, p = 0.010) and (F(6, 297) = 6.072, p < 0.001) respectively. For waist circumference percentile and body fat percentage, the intervention group experienced a significant reduction compared to the wait-list group, within the obese subgroup ((F(6, 297) = 3.998, p = 0.001) and within the overweight subgroup (F(6, 201) = 2.526, p = 0.022).. The four-month REDUCE intervention programme was effective in reducing childhood adiposity. Further research using this approach needs to be conducted including cost-effectiveness studies before implementing it in a child obesity prevention programme..

The prevalence of type 2 diabetes among Malaysian adults has increased by more than two folds over the past two decades. Strategies to collaborate with the existing community partners may become a promising channel for wide-scale dissemination of diabetes prevention in the country. The objectives of this study were to determine the effects of community-based lifestyle interventions delivered to adults with prediabetes and their health-related quality of life as compared to the usual care group.. This was a quasi-experimental study conducted in two sub-urban communities in Seremban, Malaysia. A total of 268 participants with prediabetes aged between 18 to 65 years old were assigned to either the community-based lifestyle intervention (Co-HELP) (n = 122) or the usual care (n = 146) groups. The Co-HELP program was delivered in partnership with the existing community volunteers to incorporate diet, physical activity, and behaviour modification strategies. Participants in the Co-HELP group received twelve group-based sessions and two individual counselling to reinforce behavioural change. Participants in the usual care group received standard health education from primary health providers in the clinic setting. Primary outcomes were fasting blood glucose, 2-hour plasma glucose, and HbA1C. Secondary outcomes included weight, BMI, waist circumference, total cholesterol, triglyceride, LDL cholesterol, HDL cholesterol, systolic and diastolic blood pressure, physical activity, diet, and health-related quality of life (HRQOL).. An intention-to-treat analysis of between-groups at 12-month (mean difference, 95% CI) revealed that the Co-HELP participants' mean fasting plasma glucose reduced by -0.40 mmol/l (-0.51 to -0.28, p<0.001), 2-hour post glucose by -0.58 mmol/l (-0.91 to -0.24, p<0.001), HbA1C by -0.24% (-0.34 to -0.15, p<0.001), diastolic blood pressure by -2.63 mmHg (-3.79 to -1.48, p<0.01), and waist circumference by -2.44 cm (-4.75 to -0.12, p<0.05) whereas HDL cholesterol increased by 0.12 mmol/l (0.05 to 0.13, p<0.01), compared to the usual care group. Significant improvements were also found in HRQOL for both physical component (PCS) by 6.51 points (5.21 to 7.80, p<0.001) and mental component (MCS) by 7.79 points (6.44 to 9.14, p<0.001). Greater proportion of participants from the Co-HELP group met the clinical recommended target of 5% or more weight loss from the initial weight (24.6% vs 3.4%, p<0.001) and physical activity of >600 METS/min/wk (60.7% vs 32.2%, p<0.001) compared to the usual care group.. This study provides evidence that a culturally adapted diabetes prevention program can be implemented in the community setting, with reduction of several diabetes risk factors and improvement of HRQOL. Collaboration with existing community partners demonstrated a promising channel for the wide-scale dissemination of diabetes prevention at the community level. Further studies are required to determine whether similar outcomes could be achieved in communities with different socioeconomic backgrounds and geographical areas.. IRCT201104106163N1.

A randomised trial was carried out to determine the effect of supplementation of fish oil among 51 children with leukaemia aged 4 to 12 years on appetite level, caloric intake, body weight and lean body mass. They were randomly allocated into the trial group (TG) and the control group (CG). At baseline, 30.8% of TG subjects and 44.0% of CG subjects were malnourished and 7.7% of subject from TG and 28.0% from CG were classified as stunted. The majority of subjects from TG and CG were in the mild malnutrition category for mid upper arm muscle circumference (MUAMC)-for-age. The TG group showed significant increment in MUAMC (0.13 cm vs -0.09 cm) compared with CG at 8 weeks (p<0.001). There was a significant higher increase for appetite level (0.12±0.33) (p<0.05) and an increasing trend on energy and protein intake in the TG group (213±554 kcal; 3.64 ±26.8 g) than in the CG group. In conclusion, supplementation of fish oil has a positive effect on appetite level, caloric intake and MUAMC among children with leukaemia.

A study to determine the effect of antihelminthic treatment on growth and nutritional status was undertaken on 103 children in the second grade of primary school, 71 of whom were found to be infected with Ascaris lumbricoides or Trichuris trichiura. The median Ascaris and Trichuris intensities in the infected group were 19,600 (range; 0-488,000) and 2,800 (range; 0-84,600) eggs per gram of feces respectively. Forty-three children harbored both types of worm. Fourteen weeks after two 400 mg doses of albendazole were administered to infected children, the increases in weight, height, weight for age, height for age and weight for height were significantly higher among infected children than controls who were uninfected at baseline. The observed gains were independent of sex and socioeconomic status. Decrease in log transformed Trichuris intensity correlated with increases in weight (r=0.24; p=0.02) and weight for age (r=0.20; p=0.06) but decrease in Ascaris intensity did not correlate with increases in any of the anthropometric parameters. The results suggest that antihelminthic treatment has beneficial short-term effects on growth and nutritional status of a modest magnitude among early primary schoolchildren in the area.

To access the effectiveness of the treatment of soil-transmitted helminthiasis (STH) on the growth of primary school children, 353 children were block stratified to receive either mebendazole plus pyrantel oxantel pamoate every three months or a placebo. The children were followed for two years with 89% completing the trial. Follow-up stools indicated that the treatment was efficacious for ascariasis and trichuriasis. There was virtually no hookworm infection. The children were malnourished as measured by the number below -2 SD of height and weight standards. There was no difference in height or weight between the treatment and control groups by sex initially or at the end of two years of follow-up. The treatment of Ascaris and Trichuris had no effect on growth parameters. The effect of STH on growth may be mediated through hookworm infections.

We estimated individual and population Michaelis-Menten pharmacokinetic parameters for phenytoin (DPH) in epileptic patients attending our neurology clinic using the computer programme. OPT. Our results agreed well with literature values but were lower than those we obtained earlier in a smaller number of patients. The Km was independent of age, weight and sex but there was a weak, correlation between Vm and body weight. We conclude that the use of population Vm and Km in normograms could lead to errors in DPH dose estimations as they correlated very poorly with patient characteristics. OPT was easy to use and sufficiently accurate for deriving dose estimates in routine patients. Its use would enable practitioners to generate their patients' own parameters for use in individual dosage adjustments. The estimates can subsequently be updated as more data become available.

Most studies reporting prevalence of obesity use actual weight and height measurements. Self-reported weight and height have been used in epidemiological studies as they have been shown to be reliable, convenient, and inexpensive alternatives to actual measurements. However, the accuracy of self-reported weight and height might vary in different regions because of the difference in health awareness and social influences. This study aims to determine the accuracy and reliability of self-reported weight and height compared to actual measured weight and height among adults in Malaysia. This was a cross-sectional study conducted at the community level during blood pressure screening campaigns. Participants self-reported their weight and height in a questionnaire survey. Their weight and height were validated using measurements by researchers on the same setting. Body mass index (BMI) was defined as underweight (<18.5kg/m2), normal (18.5-22.9 kg/m2), overweight (23-27.4 kg/m2) and obesity (≥27.5 kg/m2). Bland-Altman analysis, intraclass correlation coefficients and weighted Kappa statistics were used to assess the degree of agreement between self-reported and measured weight and height. A total of 2781 participants were recruited in this study. The difference between the mean self-reported and measured weight and height were 0.4 kg and 0.4 cm respectively. Weighted Kappa statistics analysis showed that there was a substantial agreement between the BMI classifications derived from self-reported and actual measurement (ҡ = 0.920, p<0.001). There was no marked difference in the sensitivity and specificity of self-reported BMI among Malaysian adults by gender. We observed substantial agreement between self-reported and measured body weight and height within a sample of Malaysian adults. While self-reported body weight showed weaker agreement with actual measurements particularly for obese and overweight individuals, BMI values derived from self-reported weight and height were accurate for 88.53% of the participants. We thus conclude that self-reported height and weight measures may be useful for tracking and estimating population trends amongst Malaysian adults.

This study aims to validate two predictive formulas of weight estimating strategies in children with special needs, namely the Cattermole formula and the Mercy formula.. A cross-sectional study with a universal sampling of children and adolescents with special needs aged 2-18 years old, diagnosed with cerebral palsy, down syndrome, autism and attention-deficit/hyperactivity disorder was conducted at Community-Based Rehabilitation in Central Zone Malaysia. Socio-demographic data were obtained from files, and medical reports and anthropometric measurements (body weight, height, humeral length, and mid-upper arm circumference) were collected using standard procedures. Data were analysed using IBM SPSS version 26. The accuracy of the formula was determined by intraclass correlation, prediction at 20% of actual body weight, residual error (RE) and root mean square error (RMSE).. A total of 502 children with a median age of 7 (6) years were enrolled in this study. The results showed that the Mercy formula demonstrated a smaller degree of bias than the Cattermole formula (PE = 1.97 ± 15.99% and 21.13 ± 27.76%, respectively). The Mercy formula showed the highest intraclass correlation coefficient (0.936 vs. 0.858) and predicted weight within 20% of the actual value in the largest proportion of participants (84% vs. 48%). The Mercy formula also demonstrated lower RE (0.3 vs. 3.6) and RMSE (3.84 vs. 6.56) compared to the Cattermole formula. Mercy offered the best option for weight estimation in children with special needs in our study population.

The coronavirus disease 2019 (COVID-19) isolation has altered individuals' food purchasing behaviour and dietary intake patterns. Therefore, this study aims to investigate the changes in dietary intake patterns and their impacts on the weight status of young adults in Malaysia during the COVID-19 lockdown.. This cross-sectional study involved 1045 young adults in Malaysia. The changes in dietary intake patterns were assessed using the Dietary Diversity Questionnaire with slight modifications, while anthropometric measurements including body height, body weight before the pandemic and current body weight were self-reported.. Overall, nearly half of the respondents (48.8%) gained weight during the confinement, with an average increment of 4.06 ± 3.23 kg. Of 1045, 45.3% reported consuming more fruits and 60.2% had higher plain water intake during the pandemic. It is observed that 41.0% to 66.8% of the young adults changed their dietary intake patterns during the pandemic. Increased consumption in cereals and grains (β = 0.084,. In conclusion, the enforcement of the Movement Control Order (MCO) drove up the prevalence of overweight/obesity among young adults in Malaysia. Increased consumption of cereals and grains and oils and fats contributed to weight gain in the pandemic lockdown. Nonetheless, a noticeable proportion of young adults in Malaysia shifted to a healthier food choice by increasing the consumption of fruits and vegetables.

The study assessed whether self-reported height, weight and derived body mass index (BMI) can provide an accurate measure of anthropometric data in a multiethnic adult population in Singapore.. Standardised anthropometric measurements were compared against the self-reported values from 5,132 adult residents in a cross-sectional, epidemiological survey. Discrepancies in self-reports from measurements were examined by comparing overall mean differences. Intraclass correlations, Cohen's kappa and Bland-Altman plots with limits of agreement, and sub-analysis by sex and ethnicity were also explored.. Data were obtained from 5,132 respondents. The mean age of respondents was 43.9 years. Overall, the height was overestimated (0.2cm), while there was an underestimation of weight (0.8kg) and derived BMI (0.4kg/m2). Women had a larger discrepancy in height (0.35cm, 95% confidence interval [CI] 0.22 to 0.49), weight (-0.95kg, 95% CI -1.11 to -0.79) and BMI (-0.49kg/m2, 95% CI -0.57 to -0.41) compared with men. Height reporting bias was highest among Indians (0.28cm, 95% CI 0.12 to 0.44) compared with Chinese and Malays, while weight (-1.32kg, 95% CI -1.53 to -1.11) and derived BMI (-0.57kg/m2, 95% CI -0.67 to -0.47) showed higher degrees of underreporting among Malays compared with Chinese and Indians. Substantially high self-reported versus measured values were obtained for intraclass correlations (0.96-0.99,. Self-reported anthropometric estimates can be used, particularly in large epidemiological studies. However, sufficient care is needed when evaluating data from Indians, Malays and women as there is likely an underestimation of obesity prevalence.

The use of dietary supplements is prevalent among many groups worldwide. However, few studies have examined their use among government employees. The aim of this cross-sectional study was to determine the association among sociodemographic characteristics, body weight status, and energy intake with dietary supplement use among government employees in Putrajaya, Malaysia. Simple random sampling was used to select a sample of 460 government employees from six ministries in Putrajaya, Malaysia. The data used in this study were collected through anthropometric measurements (height, weight, % body fat, waist and hip circumferences), a self-administered questionnaire (sociodemographic characteristics and dietary supplements use), and an interviewer-administered questionnaire (24-hour dietary recall; fruit and vegetable intake). The results indicated that the prevalence of dietary supplement use was 55.4%, with vitamin C (38.4%) being the most popular type of dietary supplement. Health issues (80.8%) were the most common reason for usage, internet (59.2%) was the main source of information, and pharmacies (71.8%) were the most indicated places to purchase dietary supplements. A multivariate analysis showed that participants who were female, married, had better monthly income, lived within a smaller household size, had a normal body mass index, classified as having unhealthily high body fat percentage, did not skip breakfast, and consumed at least five servings of fruits and vegetables per day were significantly more likely to use dietary supplements. In conclusion, health-conscious groups were more prone to consume dietary supplements, and due to the high prevalence of dietary supplement use, dissemination of accurate scientific information regarding dietary supplements is highly recommended among government employees.

Children with Autism Spectrum Disorder (ASD) of different levels of symptom severity may exhibit a wide range of behaviours and characteristics. There is a limited nutrition-related study on children with ASD of different severity in Malaysia.. This cross-sectional study aims to determine the association between sociodemographic factors, parental factors, and lifestyle factors with autism severity in children with ASD.. A total of 224 children with ASD were included in this study. Their mothers completed a self-administered questionnaire on sociodemographic characteristics, autism severity, parenting style, parental feeding practices, parenting stress, child's sleep habits and eating behaviours.. As high as 78.1 % of the children with ASD demonstrated a high level of autism severity. Multiple linear regression showed that father's employment status (B = 6.970, 95 % CI = 3.172, 10.768, p < 0.001) and perceived child weight (B = 3.338, 95 % CI = 1.350, 5.327, p = 0.001) predicted autism severity.. Children with ASD in this study had a high level of autism severity. Regular anthropometric measurements by healthcare professionals should be conducted at the autism intervention centres. It is important to have multidisciplinary collaboration in future research to develop customised guidelines for parents with autistic children.

Body weight perception may determine the practice of proper weight management. The objective of this study was to measure the agreement between body weight perception and actual body weight status and its associated factors among late adolescents in Kuantan, Malaysia.. A cross-sectional study was conducted from April to October 2018 among 479 adolescents aged 17-19 years old from seven institutions of higher learning in Kuantan. Body weight status was described as body mass index (BMI). Weight and height were measured, and BMI was calculated. Validated, self-administered Figure Rating Scale (FRS) questionnaires were used. Agreement between BMI and body weight perception was calculated using Kappa statistics. Logistic regression was employed to examine the association between body weight perception and sociodemographic variables.. More than one-third (35.3%) of the respondents misjudged their own body weight. More than one third of the respondents (38.7%) who were underweight, misperceived themselves as having normal weight whilst 31.7% of obese respondents identified themselves as overweight. The agreement between body weight perception and body mass index was moderate (k0.46, p<0.01).. Body weight perception was in moderate agreement with actual weight in late adolescents. Accurate body weight perception is an important factor in late adolescent's weight management behaviour. Hence, health education related to body weight management should be emphasized among this age group.

With the on-going interest in implementing school policies to address the problem of childhood obesity in Malaysia, there is urgent need for information about the association between school environment and children's weight status. This study aims to investigate the association between school environmental factors (physical, economic, political and sociocultural) with BMI of school children in Terengganu. The school environment factors were assessed using a set of validated whole-school environmental mapping questionnaires, consisting of 76 criteria with four domains; physical environment (41 criteria), economic environment (nine criteria), political environment (nine criteria) and sociocultural environment (17 criteria). This involved face-to-face interview sessions with 32 teachers from 16 schools (eight rural and eight urban). In addition, 400 school children aged between 9 and 11 years of the selected schools were assessed for BMI (WHO 2007 reference chart), dietary intake (food frequency questionnaire (FFQ)) and physical activity level (physical activity questionnaire for children (PAQ-C)). Multiple regression was used to examine the association between school environment factors and BMI of the school children. Seven school environment criteria were found to be associated with BMI of school children when it was adjusted for calorie intake and physical activity level. About 33.4% of the variation in BMI of school children was explained by health professional involvement, simple exercise before class, encouragement to walk/ride bicycle to/from school, no high-calorie food sold, healthy options of foods and drinks at tuck shop, availability of policy on physical activity and training teacher as a role model. Policy makers should make urgent actions to address the obesogenic features of school environments. It should strive towards setting up healthy school environment and improving school curricula to promote healthy behaviours among the school children.

To investigate the protective effects of Tualang honey against the toxicity effects induced by cadmium (Cd) on the ovary.. A total of 32 female Sprague Dawley rats were taken and randomly divided into four groups (n = 8). Throughout the experimental period of 6 weeks, negative control-NC (vehicle deionized water), positive control-CD (Cd at 5 mg/kg), Tualang honey followed by Cd exposure-TH (Tualang honey at 200 mg/kg and Cd at 5 mg/kg) and Tualang honey control-THC (Tualang honey at 200 mg/kg) groups, were administered orally on a daily basis.. Rats exposed to Cd were significantly higher in ovarian weight, number of antral and atretic follicles as compared to the NC group. The disruptive effects of Cd on ovarian follicles were associated with a disruption in gonadotropin hormones and decreases in follicular stimulating hormone (FSH) and luteinizing hormone (LH). Moreover, a significant formation of oxidative stress in ovarian Cd-exposed rats has been proven by increasing the level of lipid peroxidation products (malondialdehyde) and decreasing the levels of enzymatic antioxidant (catalase). Interestingly, a daily supplementation of high antioxidant agents such as Tualang honey in these animals, caused significant improvements in the histological changes. Additionally, less atretic follicles were observed, restoring the normal level of LH and FSH (P < 0.001), and normalizing the ovarian malondialdehyde (P < 0.05) and catalase levels in comparison with CD group (P < 0.05).. Tualang honey has protective effects against Cd-induced ovarian toxicity by reducing morphological abnormalities, restoring the normal levels of gonadotropin hormones and stabilizing equilibrium levels of lipid peroxidation and antioxidant enzyme in ovaries of rats.

Body weight is a factor, with body weight perception a mediator, toward being a victim of bullying. This study aimed to explore the association between body weight, body weight perception, and bullying among students 13 to 17 years of age in Malaysia. Data were collected using a self-administered questionnaire. A 2-stage stratified cluster sampling design was used, and 212 schools across Malaysia were selected for this survey. Body weight was measured and body weight perception was the student's reflection of their body weight. The prevalence of being bullied among adolescents in Malaysia was 16.2%. Being too thin or being obese increased the probability of being bullied. Students with a normal body mass index, but with a misperception of their body weight, also had increased odds of being bullied. Obesity prevention, together with instilling positive body weight perception, should be part of all programs directed toward tackling the problem of bullying.

Dietary composition is the cornerstone of weight management. This study aimed to investigate the effect of nutrient intakes on anthropometric profiles among university students.. This cross-sectional study was conducted among 411 students aged 18-29 years, purposive sampled from a selected private university in Klang Valley, Malaysia. Anthropometric profiles were measured. Nutrient intakes were assessed by 3-day 24-hour diet recalls.. Respondents on average had adequate macronutrient intakes, however, total consumption of dietary fiber and micronutrients were fell short of recommended levels. Significant negative associations were found between body mass index (BMI) and all the macronutrients, calcium, thiamine, riboflavin and niacin. Body fat percentage was significantly associated with all the macronutrients, calcium, zinc, thiamine and niacin. Significant inverse associations were also found between waist circumference and carbohydrate, fiber, thiamine, riboflavin and niacin. Visceral fat showed significant inverse associations with carbohydrate, fat, fiber, thiamine, riboflavin and niacin. Further, after adjusting for sex, gender and race, BMI was associated with niacin (β=-0.161, p=0.027). Body fat percentage was also found significantly associated with niacin (β=-0.180, p=0.002) and riboflavin (β=-0.132, p=0.014).. Micronutrients, especially B vitamins, are important in weight management among the young adults.

Differences in wing morphology are predicted to reflect differences in bat foraging strategies. Experimental tests of this prediction typically assess the relationship between wing morphology and a measures of flight performance on an obstacle course. However, studies have lacked measures of obstacle avoidance ability true scores, which may confound interpretation of ability across the range of presented tasks. Here, we used Rasch analysis of performance in a collision-avoidance experiment to estimate the ability of bat species to fly through vegetative clutter. We refer to this latent trait as 'clutter negotiating ability' and determined the relationships between clutter negotiating ability and wing morphology in 15 forest insectivorous bat species that forage in the densely cluttered rainforests of Malaysia. The clutter negotiating ability scores were quantified based on individual responses of each species to 11 different obstacle arrangements (four banks of vertical strings 10-60 cm apart). The tasks employed for the collision-avoidance experiment were reliable and valid, although Rasch analysis suggested that the experiment was too easy to discriminate completely among the 15 species. We found significant negative correlations between clutter negotiating ability and body mass, wingspan, wing loading and wing area but a positive significant correlation with wingtip area ratio. However, in stepwise multiple regression analyses, only body mass and wing loading were significant predictors of clutter negotiating ability. Species fell into clusters of different clutter negotiating ability, suggesting a potential mechanism for resource partitioning within the forest interior insectivorous ensemble.

Early detection of malnutrition in hospitalized children helps reduce length of hospital stay and morbidity. A validated nutrition tool is essential to correctly identify children at risk of malnutrition or who are already malnourished. This study compared the use of the Subjective Global Nutrition Assessment (SGNA, nutrition assessment tool) and Screening Tool for the Assessment of Malnutrition in Paediatrics (STAMP, nutrition screening tool) with objective nutritional parameters to identify malnutrition in hospitalized children.. A cross-sectional study was carried out in two general paediatric wards in a public hospital. SGNA and STAMP were performed on 82 children (52 boys and 30 girls) of age 1-7 years. The scores from both methods were compared against Academy of Nutrition and Dietetics/American Society of Parental and Enteral Nutrition Consensus Statement for identification of paediatric malnutrition. The objective measurements include anthropometry (weight, height and mid-arm circumference), dietary intake and biochemical markers (C-reactive protein, total lymphocytes and serum albumin). Kappa agreement between methods, sensitivity, specificity and cross-classification were computed.. SGNA and STAMP identified 45% and 79% of the children to be at risk of malnutrition, respectively. Using a compendium of objective parameters, 46% of the children were confirmed to be malnourished. The agreement between SGNA and objective measurements (k = 0.337) was stronger than between STAMP and objective measurements (k = 0.052) in evaluating the nutritional status of hospitalized children. SGNA also has a 4-fold higher specificity (70.45%) than STAMP (18.18%) in detecting children who are malnourished.. SGNA is a valid nutrition assessment tool in diagnosing malnutrition status among hospitalized children in Malaysia. The discrepancy in specificity values between the two methods explains the distinguished roles between SGNA and STAMP. The use of STAMP will have to be followed up with a more valid tool such as SGNA to verify the actual nutrition status of the paediatric population.

This study examined the factors associated with body mass index (BMI) categories of Malaysian adolescents by physical activity (PA) status.. Data were obtained from the 2012 Malaysia Global School-based Student Health Survey. Generalized ordered logit regression analysis was conducted on 24 339 adolescents by PA status.. Early- (ages 11-13) and middle-stage (ages 14-16) adolescents were associated with higher overweight and obesity risks than their older peers (ages 17-18). Male adolescents faced higher underweight and obesity likelihoods than females. Hunger due to food shortage at home was associated with higher likelihoods of underweight and normal weight BMI categories. Smokers were more likely to be underweight or normal weight than non-smokers. Segmented-sample analysis by PA status indicated that, while the direction of associations was parallel across PA status, the magnitudes of association between age, hunger and smoking status with BMI status were greater among active than inactive adolescents.. Male adolescents faced a dual burden of underweight and obesity. Other sociodemographic and dietary-lifestyle factors were associated with adolescent BMI categories. Segmented-sample analysis by PA status uncovered varying associations between factors that would otherwise be masked in pooled sample analysis. Public health authorities should take these factors into consideration when deliberating programs to ensure healthy adolescent body weight.

For the past decades, Malaysia has seen an increased prevalence of overweight and obesity which leads to significant health threats. Physical activity is beneficial in maintaining healthy body weight. The objective of this study was to measure physical activity of adults in Malaysia using objective measurement (accelerometer) and self-reported methods, as well as to determine their associations with (body mass index (BMI) and waist circumference (WC) measurements.. Four-hundred and ninety Malaysian adults (n = 490) aged 20 to 65 years old participated in this cross-sectional study. Their body weight, height, and WC measurements were measured according to standard procedures. Physical activity was assessed objectively with accelerometers for five to seven consecutive days. The International Physical Activity Questionnaire (IPAQ) was used to estimate the amount of time spent on various domains of physical activity. Mixed models were used to determine the associations between physical activity variables and both BMI and WC.. The mean value of objectively measured moderate-to-vigorous physical activity (MVPA) was 13.5 min per day, in which male participants recorded a significantly higher amount of time compared to females. On the other hand, the mean self-reported total physical activity was 380 min per week; male participants reported a significantly higher amount of time on physical activity in the occupation/work and leisure/recreation domains while female participants spent significantly more time in the domestic/household chores domain. We also observed that the mean values of objectively measured total MVPA, self-reported time spent on walking for leisure/recreation, and total time amount of time spent on MVPA for leisure/recreation were significantly higher among participants with BMI of less than 25 kg/m. Objectively measured MVPA was inversely associated with BMI, but not WC measurement. No significant association was observed between self-reported total physical activity and physical activity time measures across domains with both BMI and WC measurement.

The Functionality Appreciation Scale (FAS; Alleva et al., 2017) is a 7-item measure of an individual's appreciation of their body for what it can do and is capable of doing. To date, its psychometric properties have not been examined beyond the parent study and outside English-speaking samples. To rectify this, we examined the psychometric properties of a Bahasa Malaysia (Malay) translation of the FAS. An online sample of 815 Malaysia citizens completed a Malay translation of the FAS, along with validated measures of body appreciation, weight discrepancy, drive for muscularity, perceived pressure from and internalisation of appearance ideals, self-esteem, and trait mindfulness. Exploratory factor analyses supported a 1-dimensional factor structure of FAS scores, which was upheld using confirmatory factor analysis. FAS scores were also invariant across sex and there was no significant sex difference in scores. Construct validity was generally supported through significant associations with the additional measures included in the study. Incremental validity was also established insofar as functionality appreciation predicted self-esteem over-and-above the variance accounted for by other body image measures. The availability of the Malay FAS will be of use to scholars in Malaysia, but establishing cross-linguistic invariance will be an important next step.

Whole grains play an important role in regulating body weight. However, interventions aimed to increase whole grains consumption have had limited impact on body mass index for age z-score (BAZ) due to insufficient understanding of knowledge, attitudes and practices (KAP) toward whole grains. This survey aimed to evaluate whole grains KAP among schoolchildren, as well as to investigate the associations of whole grains KAP with BAZ among the schoolchildren in Negeri Sembilan, Malaysia. This cross-sectional survey was conducted among 380 schoolchildren aged 9-11 years, cluster sampled from six randomly selected schools. Data were collected through a validated self-administered guided questionnaire. Body weight and height were measured. A majority of the schoolchildren had normal body weight (56.6%), moderate whole grains knowledge (42.6%), as well as neutral attitudes (66.1%) and poor practices (58.9%) toward whole grains consumption. Significant positive associations were found between knowledge and attitudes (r = 0.337; p < .01), attitudes and practices (r = 0.150; p < .01) and knowledge and practices (r = 0.190; p < .01). Further, whole grains consumption's practices was associated with BAZ after adjusting for sex, gender, race and area where children lived in (p < .001). Outcome of this present study implies that positive change in whole grain knowledge would help to inculcate positive attitudes and cultivate better practices toward whole grain consumption, which may be useful in lower BAZ among schoolchildren in Negeri Sembilan, Malaysia. This study reveals the importance of KAP toward whole grains among children to assist in identification of specific preventive childhood obesity actions.

Given the increasing prevalence of childhood obesity in Malaysia, examination of family environmental factors is warranted. Reviews from developed countries report inconsistent findings on the relationship between parental-child feeding practices and child weight-related health outcomes. The current study aimed to examine parent-child feeding practices by familial-child characteristics in Malaysia.. The Family Diet Study was conducted with urban Malay families and included a child aged 8-12 years and their main carer(s). Seven domains of parent-child feeding practices were assessed using the child feeding questionnaire and familial demographics, including socio-economic status, child anthropometry and dietary intake were collected. Inferential statistics were used to explore the relationships between variables.. Of the 315 families enrolled, 236 completed all measures, with the majority of parent-reporters being mothers (n = 182). One-third of the children were classified as overweight/obese. Three domains of parent-child feeding practices had median scores of 4.0 out of 5.0 [concern about child overweight (CCO) (Interquartile range (IQR): 3.3, 4.7); pressure-to-eat (PTE) (IQR: 3.3, 4.5) and food monitoring (IQR: 3.0, 5.0)]. The domain of 'perceived child overweight' was positively associated with child age (r = 0.45, p < 0.001). Children who were overweight (F = 37.4; p < 0.001) and under-reported energy intake (F = 13.1; p = 0.001) had higher median scores for the parental perception of risk of child being overweight. Median scores for the CCO and PTE domains were significantly higher in low-income families (F = 7.87; F = 9.75; p < 0.05, respectively).. Malay parents in this present study are concerned about their child's weight, particularly for those overweight. Family size, household income, and child weight status significantly influence parent-child feeding practices. Further research examining the cultural context of family environmental factors related to childhood obesity is warranted within Malaysia.

There is increased use of the 2-min walk test (2MWT) to assess functional exercise capacity. However, the distance achieved during this test may be difficult to interpret in the absence of reference values from a local population. Regression equations to estimate the 2-min walk distance (2MWD) only exist for American and Brazilian populations. The objective of this study was to develop regression equations to estimate the 2MWD in Malaysian adults who were free from major health problems.. Eighty-seven adults (43 males; mean ± SD age: 57.1 ± 9.6 years) performed two 2MWT using a standardized protocol. Heart rate (HR) was recorded every 30 s during the test. Stepwise multiple regression analysis was performed using age, gender, height, weight and change in HR (ΔHR) as independent variables, and better of the two 2MWD as the dependent variable. A second regression equation, without ΔHR, was planned if ΔHR was retained as one of the predictors of the 2MWD in the first equation.. The better of the two 2MWD was 200 ± 34 m. Males walked 33 ± 6 m further than females (P < 0.001). The two regression equations were 196 - 1.1 × age, years + 1.0 × ΔHR, bpm + 31.2 × gender (R. The equations derived in this study may facilitate the interpretation of the 2MWD in clinical populations in Malaysia, as well as in countries with similar cultural backgrounds to Malaysia.

The present study aimed to (i) calculate body-weight- and BMI-for-age percentile values for children aged 0·5-12 years participating in the South-East Asian Nutrition Survey (SEANUTS); (ii) investigate whether the pooled (i.e. including all countries) SEANUTS weight- and BMI-for-age percentile values can be used for all SEANUTS countries instead of country-specific ones; and (iii) examine whether the pooled SEANUTS percentile values differ from the WHO growth references.. Body weight and length/height were measured. The LMS method was used for calculating smoothened body-weight- and BMI-for-age percentile values. The standardized site effect (SSE) values were used for identifying large differences (i.e. $\\left| {{\\rm SSE}} \\right|$ >0·5) between the pooled SEANUTS sample and the remaining pooled SEANUTS samples after excluding one single country each time, as well as with WHO growth references.. Malaysia, Thailand, Vietnam and Indonesia.. Data from 14 202 eligible children.. The SSE derived from the comparisons of the percentile values between the pooled and the remaining pooled SEANUTS samples were indicative of small/acceptable (i.e. $\\left| {{\\rm SSE}} \\right|$ ≤0·5) differences. In contrast, the comparisons of the pooled SEANUTS sample with WHO revealed large differences in certain percentiles.. The findings of the present study support the use of percentile values derived from the pooled SEANUTS sample for evaluating the weight status of children in each SEANUTS country. Nevertheless, large differences were observed in certain percentiles values when SEANUTS and WHO reference values were compared.

The epidemic of obesity in developed countries is commonly associated with poor dietary habit and sedentary lifestyle. However, other determinants, including education background and family income, may contribute towards the problem especially in developing countries. This study aimed to determine the influence of socioeconomic status (SES) on obesity among 12-year-old school adolescents in Terengganu, Malaysia. Body weight and height were measured and BMI was categorised based on WHO z-score cut-off points. Information was obtained from self-reported questionnaire on parents' education background, family income and occupation. A total of 3,798 school adolescents aged 12 years (44% boys and 56% girls) were recruited. There was no significant difference in BMI status between boys and girls, or between rural and urban participants. There were significant differences between BMI categories and gender, household income and SES level within rural areas. In the urban areas, significant differences were found between BMI categories and gender, parents' occupational and educational level, household income and size, and SES level. A logistic regression model found several SES factors to be predictors of obesity in this population, namely, gender, household size, father's occupation level, household income level and SES level. Each component of SES has been significantly associated with the BMI category of school adolescents, particularly in the urban areas. This suggests the requirement of multifaceted approaches, including the role of family, society and authorities, in the effort to curtail adolescent obesity.

Obesity is a risk factor for co-morbidities such as diabetes, hypertension, osteoarthritis and cardiovascular diseases. However, it is unclear if the presence of co-morbidities has any effect on the magnitude of body composition changes following weight reduction programmes. Thus, this study aimed to determine changes in body composition among obese housewives with and without co-morbidities after they participated in a weight loss intervention.. This is a follow-up study among 84 obese housewives without co-morbidities aged 18 to 59 years old who previously participated as a control group (delayed intervention, G1) in the My Body is Fit and Fabulous at Home (MyBFF@home) Phase II. Baseline data were obtained from 12 month data collection for this group. A new group of 42 obese housewives with co-morbidities (G2) were also recruited. Both groups received a 6 month intervention (July-December 2015) consisting of dietary counselling, physical activity (PA) and self-monitoring tools (PA diary, food diary and pedometer). Study parameters included weight, height, waist circumference, blood pressure and body compositions. Body compositions were measured using a bioelectrical impedance analysis device, Inbody 720. Descriptive and repeated measures ANOVA analyses were performed using SPSS 21.. There were reductions in mean body fat, fat mass and visceral fat area, particularly among obese women without co-morbidities. There were also decreases fat and skeletal muscle from baseline to month six with mean difference - 0.12 (95% CI: -0.38, 0.14) and visceral fat area from month three to month six with mean difference - 9.22 (- 17.87, - 0.56) for G1. G2 showed a decreasing pattern of skeletal muscle from baseline to month six with mean difference - 0.01(95% CI: -0.38, 0.37). There was a significant difference for group effect of visceral fat area (p < 0.05) with mean difference of - 11.49(95% CI: -20.07, 2.91). It showed that the intervention programs was effective to reduce visceral fat area compared to other part of body composition.. Obese participants without co-morbidities showed more desirable changes in body composition. Visceral fat area was reduced regardless of morbidity status. Weight management efforts are therefore not as straightforward in those with co-morbidities compared to those without, and require thorough and tailor-made strategies for a better chance of success.

The national prevalence of overweight and obesity in Malaysia has been increasing in the past 10 years and many efforts have been implemented by the Malaysian government to combat obesity problem among the Malaysian population. The aim of this paper was to describe the background of the My Body is Fit and Fabulous at home (MyBFF@home) study (Phase II).. The MyBFF@home (Phase II) was a quasi-experimental study and it was conducted among overweight and obese housewives living in the urban areas in Malaysia. In this phase, the study involved a weight loss intervention phase (6 months) and a weight loss maintenance phase (6 months). The intervention group received a standard weight loss intervention package and the control group received group seminars related to women's health. Measurements of weight, height, waist circumference, body composition, fasting blood lipids, dietary intake, physical activity, health literacy, body pain and quality of life were conducted during the study. Overweight and obese housewives from 14 People's Housing/Home Project (PHP) in Federal Territory of Kuala Lumpur (Klang Valley) were selected as control and intervention group (N = 328). Majority of the participants (76.1%) were from the low socioeconomic group. Data were analysed and presented according to the specific objectives and the needs for the particular topic in the present supplement report.. MyBFF@home is the first and the largest community-based weight loss intervention study which was conducted among overweight and obese housewives in Malaysia. Findings of the study could be used by the policy makers and the researchers to enhance the obesity intervention programme among female adults in Malaysia.

Obesity is an emerging global public health concern as it is related to chronic diseases and its impact to health related quality of life. The aim of this study was to assess the effect of weight reduction on health related quality of life (HRQOL) among obese and overweight housewives.. Data on 123 obese and overweight housewives in the intervention group from the MyBFF@home study were utilised. A validated Malaysian Malay version of Obesity Weight Loss Quality of Life (OWLQOL) questionnaire was administered at baseline and 6 months after intervention. Descriptive analysis, univariate analysis, paired t-test and multiple logistic regression were performed using SPSS Version 22.. Mean body mass index (BMI) was 31.5 kg/m. Weight loss intervention programme utilizing behavioural modification has led to a significant improvement in HRQOL among overweight and obese housewives.

The prevalence of overweight and obesity among Malaysian women remained high over the past three decades. Collaboration with existing community at-risk may be feasible for wide-scale prevention of overweight and obesity in the country. The aims of this study were to examine the impact of community-based lifestyle intervention among overweight and obese women on their anthropometric and body composition changes as compared to the usual care group.. This was a quasi-experimental study conducted in low-cost flats in Kuala Lumpur, Malaysia. A total of 255 overweight and obesity individuals aged between 18 to 59 years old were assigned to either the lifestyle intervention group (n = 169) or the usual care group (n = 146) over a period of 6 months. Individuals in the intervention group received 6 individual lifestyle counselling comprised of physical activity, diet counselling and self-monitoring components aimed to achieve at least 5% weight loss while individuals in the usual care group obtained six sessions of health care seminars from health care providers. These individuals were then followed-up for another 6 months without any intervention as part of maintenance period.. An intention-to-treat analysis of between-groups at 6-month of intervention (β, 95% CI) revealed greater changes in weight among intervention individuals' (- 1.09 kg vs. -0.99; p < 0.018) as compared to the control group. These changes were not sustained during the maintenance phase (between 6 and 12 months). Overall significant improvement at 12th month was found for visceral fat (- 0.78 vs. -0.64; p-value = 0.017), although no significant changes between groups were detected either during intervention or maintenance phase (p > 0.05). Individuals in the intervention group showed a significant increase for skeletal muscle mass (0.13 kg) than those individuals in the control group (- 0.37 kg), p = 0.033, throughout the study period.. This study provides evidence that an overweight and obesity prevention program can be implemented in a community setting, with some reduction of several anthropometric and body composition parameters.

Genetic and environmental influences on anthropometric measures can be investigated by comparing dizygotic (DZ) versus monozygotic (MZ) twins. Investigating cohorts living in different geographical areas across the globe can identify the variation in heritability versus environment.. (1) To investigate the association between birth weight and anthropometric measurements during adulthood; (2) to study the genetic and environmental influences on body measures including birth weight, weight and height among twins; and (3) to assess the variation in heritability versus environment among two cohorts of twins who lived in different geographical areas.. Twins were collected from two twin registers. Data on birth weight, adult weight and height in 430 MZ and 170 DZ twins living in two geographically distinct parts of the world were collected. A genetic analysis was performed using MX software.. Birth weight was associated with weight, height and BMI. Both MZ and DZ twins with low birth weight had shorter height during their adult life (p = 0.001), but only MZ twins with lower birth weight were lighter at adulthood (p = 0.001). Intra-pair differences in birth weight were not associated with differences in adult height (p = 0.366) or weight (p = 0.796). Additive genetic effects accounted for 53% of the variance in weight, 43% in height and 55% in birth weight. The remaining variance was attributed to unique environmental effects (15% for weight, 13% for height and 45% for birth weight and only 16% for BMI). Variability was found to be different in the two cohorts. The best fitting model for birth weight and BMI was additive genetic and non-shared environment and for weight and height was additive genetic, non-shared environment (plus common Environment).. Data suggests that the association between weight at birth and anthropometric measures in later life is influenced by both genetic and environmental factors. Living in different environments can potentially relate to variation found in the environment.

This study aimed to estimate potential reductions in case incidence of colorectal cancer attributable to the modifiable risk factors such as alcohol consumption, overweight and physical inactivity amongst the Malaysian population.. Gender specific population-attributable fractions (PAFs) for colorectal cancer in Malaysia were estimated for the three selected risk factors (physical inactivity, overweight, and alcohol consumptions). Exposure prevalence were sourced from a large-scale national representative survey. Risk estimates of the relationship between the exposure of interest and colorectal cancer were obtained from published meta-analyses. The overall PAF was then estimated, using the 2013 national cancer incidence data from the Malaysian Cancer Registry.. Overall, the mean incidence rate for colorectal cancer in Malaysia from 2008 to 2013 was 21.3 per 100,000 population, with the mean age of 61.6 years (±12.7) and the majority were men (56.6%). Amongst 369 colorectal cancer cases in 2013, 40 cases (20 men, 20 women), 10 cases (9 men, 1 woman) or 20 cases (16 men,4 women) would be prevented, if they had done physical exercises, could reduce their body weight to normal level or avoided alcohol consumption, assuming that these factors are causally related to colorectal cancer. It was estimated that 66 (17.8%;66/369) colorectal cancer cases (42 men, 24 women) who had all these three risk factors for the last 10 years would have been prevented, if they could control these three risk factors through effective preventive measures.. Findings suggest that approximately 18% of colorectal cancer cases in Malaysia would be prevented through appropriate preventive measures such as doing regular physical exercises, reducing their body weight to normal level and avoiding alcohol consumption, if these factors are causally related to colorectal cancer. Scaling-up nationwide public health campaigns tailored to increase physical activity, controlling body weight within normal limits and avoid alcohol intake are recommended. Future studies with other site-specific cancers and additional risk factors are needed.

Body weight is highly associated with overall health status. Being severely thin or obese may impose the risk of many health problems. Early detection of body mass index (BMI) status may help to reduce the associated comorbidities. Although many studies in the literature have investigated the BMI of school adolescents in Malaysia, the data on status of body weight among school adolescents in suburban states like Terengganu is limited. This study aimed to describe the body weight status of the whole population of school adolescents in all seven districts in Terengganu, Malaysia.. Using a cross-sectional study design, body weight and height were measured, and BMI was calculated and classified using WHO BMI-for-age Z-score. Data was obtained using the National Fitness Standard (SEGAK) assessment, which was uploaded in a specific Health Monitoring System (HEMS).. From a total of 62,567 school adolescents, 50.7% were boys and 49.3% were girls. Girls had significantly higher BMI than boys in age groups of 13 to 15 and 16 to 17 years old. Among boys and girls, there were significant differences in mean BMI of school adolescents between rural and urban school locations in all age groups (p < 0.001). There were also significant differences in BMI between boys and girls in all districts in Terengganu, except Kemaman and Kuala Terengganu, for all age groups (p < 0.001). Overall, the prevalence of thinness, normal, overweight and obesity were 8.4, 64.6, 15.0 and 12.0%, respectively. There were significant differences between BMI categories and genders in total participants, and within rural and urban school locations (p < 0.05). In all districts except Marang and Dungun, significant difference was also found between BMI categories and genders.. The prevalence of thinness, overweight and obesity in Terengganu were substantial. In this study, BMI category was associated with gender, age, school location and district. However, the actual effects of these factors on the prevalence of thinness and obesity among this population demand further investigation.

To determine the relationship between BMI and risk of CVD mortality and all-cause mortality among Malaysian adults.. Population-based, retrospective cohort study. Participants were followed up for 5 years from 2006 to 2010. Mortality data were obtained via record linkages with the Malaysian National Registration Department. Multiple Cox regression was applied to compare risk of CVD and all-cause mortality between BMI categories adjusting for age, gender and ethnicity. Models were generated for all participants, all participants the first 2 years of follow-up, healthy participants, healthy never smokers, never smokers, current smokers and former smokers.. All fourteen states in Malaysia.. Malaysian adults (n 32 839) aged 18 years or above from the third National Health and Morbidity Survey.. Total follow-up time was 153 814 person-years with 1035 deaths from all causes and 225 deaths from CVD. Underweight (BMI<18·5 kg/m2) was associated with a significantly increased risk of all-cause mortality, while obesity (BMI ≥30·0 kg/m2) was associated with a heightened risk of CVD mortality. Overweight (BMI=25·0-29·9 kg/m2) was inversely associated with risk of all-cause mortality. Underweight was significantly associated with all-cause mortality in all models except for current smokers. Overweight was inversely associated with all-cause mortality in all participants. Although a positive trend was observed between BMI and CVD mortality in all participants, a significant association was observed only for severe obesity (BMI≥35·0 kg/m2).. Underweight was associated with increased risk of all-cause mortality and obesity with increased risk of CVD mortality. Therefore, maintaining a normal BMI through leading an active lifestyle and healthy dietary habits should continue to be promoted.

Malnutrition is common among patients with cancer, but little attention is given to its risks and consequences.. The aim of this study is to assess the nutritional status and identify the factors associated with malnutrition among newly diagnosed patients with cancer.. Patients admitted with newly diagnosed cancer at a teaching hospital in Malaysia were recruited from January to April 2015. Nutritional status was assessed before treatment initiation, and patients were classified into three categories.. A total of 132 pretreatment patients were recruited into the study. About half were severely malnourished. Patients with stage III cancer had the highest prevalence of severe malnourishment. Clinical parameters and disease characteristics were significantly associated with nutritional status. Demographic variables were also statistically significantly associated with severe nutritional status.

Obesity is a major health concern both in developed and developing countries. The use of herbal medicines became the subject of interest for the management of obesity due to its natural origin, cost effectiveness and minimal side effects. The present study aimed at investigating anti-obesity potential of ethanolic extract from Cosmos caudatus Kunth leaf (EECCL).. In this study, the rats were randomly divided into six groups i.e., (1) Normal Diet (ND); (2) Normal Diet and 175 mg/kgBW of EECCL (ND + 175 mg/kgBW); (3) Normal Diet and 350 mg/kgBW of EECCL (ND + 350 mg/kgBW); (4) High Fat Diet (HFD); (5) High Fat Diet and 175 mg/kgBW of EECCL (HFD + 175 mg/kgBW); (6) High Fat Diet and 350 mg/kgBW of EECCL (HFD + 350 mg/kgBW). The anti-obesity potential was evaluated through analyses of changes in body weight, visceral fat weight, and blood biochemicals including total cholesterol, triglycerides, high-density lipoprotein cholesterol (HDL-c), low-density lipoprotein cholesterol (LDL-c), leptin, insulin, adiponectin, ghrelin and fecal fat content. In addition, metabolite profiling of EECCL was carried out using NMR spectroscopy.. Rats receiving EECCL together with HFD showed significant (p < 0.05) reduction in body weight gain compared to rats receiving HFD only. At the end of study, the body weight gain of EECCL treated rats was not significantly (p > 0.05) different with those of ND rats. Other related obesity biomarkers including plasma lipid profiles, insulin, leptin, ghrelin and adiponectin levels also showed significant improvement (p < 0.05). Administration of EECCL caused significant (p < 0.05) increase in fecal fat excretion, which validates the hypothesis of lipase inhibition, an anti-obesity mechanism similar to standard drug of Orlistat. The. Conclusively, EECCL showed anti-obesity properties by inhibition of intestinal lipid absorption and modulation of adipocytes markers.

To examine the relationships between self-esteem, body-esteem, emotional intelligence, and social anxiety, as well as to examine the moderating role of weight between exogenous variables and social anxiety, 520 university students completed the self-report measures. Structural equation modeling revealed that individuals with low self-esteem, body-esteem, and emotional intelligence were more likely to report social anxiety. The findings indicated that obese and overweight individuals with low body-esteem, emotional intelligence, and self-esteem had higher social anxiety than others. Our results highlight the roles of body-esteem, self-esteem, and emotional intelligence as influencing factors for reducing social anxiety.

Parental body mass index (BMI) is strongly linked with the development of offspring overweight and obesity. However, there are a limited number of studies focusing on the association of parental body mass index before pregnancy on offspring growth and body composition in early life, particularly in developing countries.. Data from the University Sains Malaysia (USM) Pregnancy Cohort which consists of 153 mother-offspring pairs were used. Data were collected using interview-administered questionnaires and anthropometric measurements were also obtained. Multiple linear regression and generalised equation estimation (GEE) were used to examine the direction and impact of the association between parental BMI and child growth and body composition (weight for age, height for age, body mass index for age, weight for height and fat mass at age 2m, 6m, and 12m). Potential confounders, including validated measures of maternal diets and physical activity during pregnancy, were considered.. Of 153 parents, one-quarter of the mothers and 42.2% of the fathers, respectively, were overweight or obese before pregnancy. A significant association was found between maternal BMI and child's weight for height z-score (WHZ) and body mass index for age z-score (BAZ).. Having high pre-pregnancy BMI may increase BMI and WAZ of offspring in early life. Findings from this study emphasise the importance of monitoring maternal weight status, particularly before and during pregnancy and early life of offspring among Malaysians.

The prevalence of stunting, thinness, overweight, and obesity among children differs by ethnicity. It is not known whether differences in body build across the ethnic groups influence the interpretation of nutritional parameters.. To explore the differences in body build across the 5 main ethnic groups in Malaysia and to determine whether differences in body build have an impact on the interpretation of nutrition indicators.. A total of 3227 children aged 2.0 to 12.9 years who participated in the South East Asian Nutrition Surveys (SEANUTS) in Malaysia were included in this analysis. Body weight, height, sitting height, wrist and knee breadths, and biceps and subscapular skinfolds were measured, and relative leg length, slenderness index, and sum of skinfolds were calculated. Z scores for height-for-age (HAZ) and body mass index-for-age (BAZ) were calculated using the World Health Organization (WHO) 2007 growth standards.. Differences in relative leg length and slenderness across the ethnic groups were correlated with HAZ and BAZ. Correction for differences in body build did, in some ethnic groups, have significant impact on the prevalence of stunting, thinness, overweight, and obesity, and the pattern of prevalence across ethnic groups changed.. At the population level, corrections for body build had only minor and mostly nonsignificant effects on prevalence, but at an individual level, corrections for body build placed a substantial number of children in different height or weight categories. Whether these misclassifications warrant additional assessment of body build in clinical practice will need further investigation.

This study describes the physical activity of primary school children according to sociodemographic characteristics and activity domains. Using the Malaysian South East Asian Nutrition Surveys data, 1702 children aged 7 to 12 years were included in the analysis. Physical activity was reported as a total score and categorized into low, medium, and high levels based on Physical Activity Questionnaire for Older Children. Higher overall activity scores were found in boys, younger age, non-Chinese ethnicity, and normal body mass index category. Sex, age, and ethnicity differences were found in structured or organized, physical education, and outside-of-school domain scores. Transport-related scores differed by age group, ethnicity, household income, and residential areas but not among the three physical activity levels. Participation of girls, Chinese, and older children were low in overall and almost all activity domains. Sociodemographic characteristics are important factors to consider in increasing the different domains of physical activity among Malaysian children.

Fermented Virgin Coconut Oil (FVCO) is widely used in the Southeast Asia as food and traditional medicine. The objective of the present study is the evaluation of chronic safety of the commercialized FVCO of Malaysia and other Southeast Asian countries. A single dose of 5000 mg/kg of FVCO was administered orally in rats (each group, n = 5) for the acute toxicity study and 175, 550 and 2000 mg/kg for sub-chronic and chronic studies (each group, n = 10), respectively. The behavior, mortality, and body weight of the rats were assessed to determine the toxic effects of FVCO. The haematology, biochemistry and histopathology of the treated rats were evaluated. The treated rats were safe with the dose of 5000 mg/kg in acute, sub-chronic and chronic indication. Abnormal clinical signs and morphology (gross necroscopy), changes of organ weight, anomalous haematology and biochemistry indexes were not found in comparison with the control (p > 0.05). In general, food and water intake were higher in the treated rats related to control. It was concluded that the presence of the antioxidant active compounds of FVCO might be the reason of safety. The structure activity relationship (SAR) provides a comprehensive mechanism to determine the safety that is the presence of the electron donating phenolic groups, carbonyl groups, and carboxylic acid in the ortho and meta position of the aromatic rings. The SAR showed the antioxidant properties of myristic acid and lauric acid determined by GC-MS analysis. This result suggests the safety of FVCO for chronic use, nutritional activity that FVCO formulation complies the requirements of regulatory agencies.

Obesity, eating disorders and unhealthy weight-loss practices have been associated with diminished growth in adolescents worldwide. Interventions that address relevant behavioural dimensions have been lacking in Malaysia. This paper describes the protocol of an integrated health education intervention namely 'Eat Right, Be Positive About Your Body and Live Actively' (EPaL), a primary prevention which aimed to promote healthy lifestyle in preventing overweight and disordered eating among secondary school adolescents aged 13-14 years old.. Following quasi-experimental design, the intervention is conducted in two secondary schools located in the district of Hulu Langat, Selangor, Malaysia. Adolescents aged 13-14 years will be included in the study. A peer-education strategy is adopted to convey knowledge and teach skills relevant to achieving a healthy lifestyle. The intervention mainly promoted: healthy eating, positive body image and active lifestyle. The following parameters will be assessed: body weight, disordered eating status, stages of change (for healthy diet, breakfast, food portion size, screen viewing and physical activity), body image, health-related quality of life, self-esteem, eating and physical activity behaviours; and knowledge, attitude and practice towards a healthy lifestyle. Assessment will be conducted at three time points: baseline, post-intervention and 3-month follow-up.. It is hypothesized that EPaL intervention will contribute in preventing overweight and disordered eating by giving the positive effects on body weight status, healthy lifestyle behaviour, as well as health-related quality of life of peer educators and participants. It may serve as a model for similar future interventions designed for the Malaysian community, specifically adolescents.. UMIN Clinical Trial Registration UMIN000024349 (Date of registration: 11th.

The objective of this case-control study was to determine anthropometric and reproductive factors associated with the development of breast cancer among women. Fifty-six newly diagnosed breast cancer patients were recruited from the Oncology Clinic, Universiti Sains Malaysia (USM), and 56 healthy female hospital employees were recruited as controls. Socio-demographic and reproductive data were obtained using a standard questionnaire. Anthropometric factors (body weight, height, body fat percentage, visceral fat and waist and hip circumference) were assessed. A high waist circumference (adjusted OR= 1.04, [95% CI: 1.00, 1.09]) and being more than 30 years of age at rst full-term pregnancy (adjusted OR=3.77, [95% CI: 1.10, 12.90]) were predictors of breast cancer development. The results of this study indicate that weight and reproductive health management should be emphasized for breast cancer prevention in Malaysia.

Growth references are useful for the screening, assessment and monitoring of individual children as well as for evaluating various growth promoting interventions that could possibly affect a child in early life.. To determine the growth centiles of Malaysian children and to establish contemporary cross-sectional growth reference charts for height and weight from birth to 6 years of age based on a representative sample of children from Malaysia.. Gender- and age-specific centile curves for height and weight were derived using the Cole's LMS method. Data for this study were retrieved from Malaysian government health clinics using a two-stage stratified random sampling technique. Assessment of nutritional status was done with the SD scores (Z-scores) of WHO 2006 standards.. Boys were found to be taller and heavier than girls in this study. The median length of Malaysian children was higher than the WHO 2006 standards and CDC 2000 reference. The overall prevalence of stunting and underweight were 8.3% and 9.3%, respectively.. This study presents the first large-scale initiative for local reference charts. The growth reference would enable the growth assessment of a Malaysian child compared to the average growth of children in the country. It is suggested that the use of WHO 2006 Child Growth Standards should be complemented with local reference charts for a more wholesome growth assessment.

To describe outcome and examine factors associated with mortality among human immunodeficiency virus (HIV)-infected children in Malaysia after anti-retroviral therapy (ART).. Retrospective and prospective data collected through March 2009 from children in four different states in Malaysia enrolled in TREAT Asia's Pediatric HIV Observational Database were analysed.. Of 347 children in the cohort, only 278 (80.1%) were commenced on ART. The median CD4 count and median age at baseline prior to ART was 272 cells/μL and 4.2 years (interquartile range (IQR): 1.4, 7.4 years), respectively. The median duration of follow-up was 3.7 years (IQR: 1.8, 6.0) with 32 deaths giving a crude mortality rate of 2.86 per 100 child-years. The mortality rate highest in the first 6 months of ART was 10.62 per 100 child-years and declined to 1.83 per 100 child-years thereafter. On univariate analyses, only baseline median CD4 percentage, weight for age z score, height for age z score and anaemia were significantly associated with mortality. Upon including all four of these predictors into a single multivariate model, only weight for age z score remained statistically significantly predictive of mortality.. Children commenced on ART had high mortality in the first 6 months especially in those with low CD4 percentage, wasting and anaemia. Poor nutritional status is an important independent predictor of mortality in this study. Besides initiating ART therapy, nutritional support and intervention must receive the utmost attention.

The browsing preference and ecological carrying capacity (ECC) of sambar deer (Cervus unicolor brookei) in acacia plantations for management and conservation of the ecosystem were investigated at Sabal Forest Reserve in Sarawak, Malaysia. The identification of the species browsed by the sambar deer was based on an observation of the plant parts consumed. ECC estimation was based on body weight (BW) and the physiological stages of animals browsed in six fenced 4-ha paddocks. Sambar deer were found foraging on only 29 out of 42 species of secondary vegetation in the acacia plantation. The remaining species are too high for the deer to reach. Planted species, Shorea macrophylla are not palatable to the deer. This augurs well for the integration of sambar deer into shorea plantations. The most frequently exploited plants were Ficus spp. Sambar deer preferred woody species more than non-woody species and they are browser animals. By producing metabolizable energy of 19,000 to 27,000 MJ/ha, the ECC was five head/ha to 5.25 head/ha. Given its contribution to the conservation of wildlife and its capacity to sustain the ecosystem, the sambar deer integrated farming system offers a promising strategy for the future of tropical forestry management.

Physical functioning and psychological resilience in adulthood is shaped during adolescence. Self-reported health-related quality of life (HRQoL) assessments during this life phase are important first-hand accounts of their well-being. This study aimed, firstly, to identify differences in HRQoL according to gender, ethnicity, socio-economic status and weight status; and secondly, to examine associations between weight status and HRQoL among an urban sample of multi-ethnic adolescents in Kuala Lumpur, Malaysia.. A cross-sectional study involving 652 adolescents (aged 13 years) was conducted in Kuala Lumpur. Weight and height were measured. Body mass index z-scores were categorized according to the International Obesity Task Force criteria. HRQoL was assessed using the Malay version of the Pediatric Quality of Life Inventory 4.0 Generic Core Scales. Univariate analyses of differences in HRQoL according to gender, ethnicity (Malays, Chinese and Indians), maternal education level and weight status were performed. Complex samples general linear model was used to examine the associations between HRQoL and weight status, adjusted for confounders.. Female adolescents reported significantly lower emotional functioning scores (mean, 95% confidence interval: 59.25, 57.33-61.17). When the three main ethnic groups were studied, Malay adolescents scored significantly lower emotional functioning scores (59.00, 57.13-60.87) compared with their Chinese peers. Adolescents with tertiary-educated mothers reported lower emotional functioning scores (57.45, 53.85-61.06) compared with those with primary-educated mothers. Obese adolescents reported poorer HRQoL scores with significantly impaired physical and social functioning after controlling for confounders.. These findings detected disparities in HRQoL among the adolescents when gender, ethnicity, maternal education level and weight status were considered. Further studies should address these health inequalities by implementing gender-specific and culturally appropriate measures to attain optimal well-being and avoid potential burden of disease.

The Pediatric Quality of Life Inventory Generic Core Scales (PedsQL) 4.0 is a generalized assessment of health-related quality of life (HRQoL) based on adolescent self-report and parent proxy-report. This study aims to determine the construct validity and reliability of PedsQL 4.0 among a sample of Malaysian adolescents and parents.. A cross-sectional study was carried out at three selected public schools in the state of Selangor. A total of 379 Malaysian adolescents completed the PedsQL 4.0 adolescent self-report and 218 (55.9%) parents completed the PedsQL 4.0 parent proxy-report. Weight and height of adolescents were measured and BMI-for-age by sex was used to determine their body weight status.. There were 50.8% male and 49.2% female adolescents who participated in this study (14.25 ± 1.23 years). The prevalence of overweight and obesity (25.8%) was four times higher than the prevalence of severe thinness and thinness (6.1%). Construct validity was analyzed using Confirmatory Factor Analysis (CFA). Based on CFA, adolescent self-report and parent proxy-report met the criteria of convergent validity (factor loading > 0.5, Average Variance Extracted (AVE) > 0.5, Construct Reliability > 0.7) and showed good fit to the data. The adolescent self-report and parent proxy-report exhibited discriminant validity as the AVE values were larger than the R(2) values. Cronbach's alpha coefficients of the adolescent self-report (α = 0.862) and parent proxy-report (α = 0.922) showed these instruments are reliable. Parents perceived the HRQoL of adolescents was poorer compared to the perception of the adolescent themselves (t = 5.92, p < 0.01). There was no significant difference in total HRQoL score between male and female adolescents (t = 0.858, p > 0.05). Parent proxy-report was negatively associated with the adolescents' BMI-for-age (r = -0.152, p < 0.05) whereas no significant association was found between adolescent self-report and BMI-for-age (r = 0.001, p > 0.05).. Adolescent self-report and parent proxy-report of the PedsQL 4.0 are valid and reliable to assess HRQoL of Malaysian adolescents. Future studies are recommended to use both adolescent self-report and parent-proxy report of HRQoL as adolescents and parents can provide different perspectives on HRQoL of adolescents.

To determine the prevalence of normal weight obesity among multi-ethnic women in Peninsular Malaysia and examine its associations with cardiometabolic risks and lifestyle behaviours.. This was a cross-sectional study involving women recruited via multi-stage sampling from six states in Malaysia. Anthropometric and body composition analysis were performed. Normal weight obese (NWO) was defined as normal body mass index for Asians and the highest tertile of % body fat (BF). Biochemical measurements included fasting lipid and blood glucose levels. Metabolic syndrome was diagnosed based on the Harmonization criteria. Participants completed self-reported questionnaires that included physical activity, smoking, alcohol consumption, fruit and vegetable intake and sleep duration.. Body mass index, %BF, cardiometabolic risk factors, lifestyle behaviours.. A total of 6854 women were recruited and the prevalence of NWO was 19.8% (95% CI: 17.3-22.5). NWO was more prevalent among the Indians and older women. NWO women had higher odds for abdominal obesity (OR: 2.64, 95% CI: 1.73-4.04), hypertriglyceridemia (2.51, 1.47-4.29) and hypertension (1.63, 1.15-2.31) compared to women with lower % body fat after adjusted for age and ethnicity. The prevalence of metabolic syndrome among NWO women was 5.4% (95% CI: 3.0-9.8). None of the lifestyle behaviours were significantly associated with NWO.. Women with NWO had cardiometabolic abnormalities including abdominal obesity, dyslipidaemia and increased blood pressure. Health promotion efforts should include NWO women who may be oblivious of their deleterious health risks.

Over recent decades, the burden of breast cancer has been increasing at an alarming rate in Asia. Prognostic research findings from Western countries may not readily be adapted to Asia, as the outcome of breast cancer depends on a multitude of factors ranging from genetic, clinical and histological predictors, to lifestyle and social predictors. The primary aim of this study is to determine the impact of lifestyle (eg, nutrition, physical activity), mental and sociocultural condition, on the overall survival and quality of life (QoL) among multiethnic Malaysian women following diagnosis of breast cancer. This study aims to advance the evidence on prognostic factors of breast cancer within the Asian setting. The findings may guide management of patients with breast cancer not only during active treatment but also during the survivorship period.. This hospital-based prospective cohort study will comprise patients with breast cancer (18 years and above), managed in the University Malaya Medical Centre (UMMC). We aim to recruit 1000 cancer survivors over a 6-year period. Data collection will occur at baseline (within 3 months of diagnosis), 6 months, and 1, 3 and 5 years following diagnosis. The primary outcomes are disease-free survival and overall survival, and secondary outcome is QoL. Factors measured are demographic and socioeconomic factors, lifestyle factors (eg, dietary intake, physical activity), anthropometry measurements (eg, height, weight, waist, hip circumference, body fat analysis), psychosocial aspects, and complementary and alternative medicine (CAM) usage.. This protocol was approved by the UMMC Ethical Committee in January 2012. All participants are required to provide written informed consent. The findings from our cohort study will be disseminated via scientific publication as well as presentation to stakeholders including the patients, clinicians, the public and policymakers, via appropriate avenues.

The consumption of beverages contributes to diet quality and overall nutrition. Studies on malted drinks, one of the widely consumed beverage choices among children in Asia, however, have received limited attention. This study aimed to examine the prevalence of malted drink consumption and explored associations of sociodemographic characteristics, nutrient intakes, weight status and physical activity levels with malted drink consumption among primary school children in Malaysia.. Data for this analysis were from the MyBreakfast Study, a national cross-sectional study conducted from April to October 2013 throughout all regions in Malaysia. A total of 2065 primary school children aged 6 to 12 years were included in the present analysis. Data on two days 24-h dietary recall or record, anthropometry, physical activity and screen time were recorded. Associations between malted drink consumption and related factors were examined using binary logistic regression, adjusting for region, area, gender, ethnicity and household income.. Among children aged 6 to 12 years, 73.5% reported consuming malted drinks for at least once per week. Consumption of malted drinks was significantly associated with region (χ(2) = 45.64, p < 0.001), gender (χ(2) = 4.41, p = 0.036) and ethnicity (χ(2) = 13.74, p = 0.008). Malted drink consumers had similar total energy intake but higher micronutrient intakes compared to non-consumers. High physical activity level (OR = 1.77, 95% CI = 1.06, 2.99) and lower screen time during weekends (OR = 0.93, 95% CI = 0.86, 0.99) were independently associated with malted drink consumption among 6 to 9 year-old children, but not among 10 to 12 year-old children. No association was observed between malted drink consumption and weight status.. Malted drink consumption is prevalent among Malaysian primary school children, particularly higher among boys, indigenous children and those who lived in the East Coast region of Malaysia. Consuming malted drinks is associated with higher micronutrient intakes and higher levels of physical activity, but not with body weight status.

In this article, the authors propose reference curves for height and weight for school children in the Kuching area, Sarawak. The school children were from primary to secondary schools (aged 6.5 to 17 years old) and comprised both genders. Anthropometric measurements and demographic information for 3081 school-aged children were collected (1440 boys and 1641 girls). Fitted line plots and percentiles for height and weight (3rd, 10th, 25th, 50th, 75th, 90th, and 97th percentiles) were obtained. The height of school boys and school girls were almost similar at the start of their school-going age. For school girls, height and weight values stabilized when they reached 16 or 17 years old but kept increasing for school boys. School boys were taller than school girls as they entered adolescence. Height differences between school boys and school girls became significantly wider as they grew older. Chinese school children were taller and heavier than those of other ethnic groups.

Greater maternal adiposity is a potentially modifiable risk factor for elevated blood pressure during pregnancy; however, the association has been little studied in Asian populations, and no study has evaluated potential differences in the adiposity-blood pressure relation between ethnic groups or interaction with gestational diabetes.. We performed a cross-sectional evaluation of a Singapore mother-offspring cohort comprising 799 pregnant Chinese, Malay and Indian women. Data on body weight, height, skinfold thickness and glycaemia (oral glucose tolerance test) were collected during the 2nd trimester; peripheral SBP and DBP were measured using an oscillometric device and central pressures by noninvasive radial applanation tonometry. The associations between adiposity measures BMI and sum of skinfold thickness and blood pressure outcomes were examined by linear regression with adjustment for potential confounders.. Higher maternal BMI was associated with elevated peripheral and central pressures: the increases in pressure (mmHg) for each kg/m(2) increase in BMI were 1.19 (95% confidence interval, 1.03-1.36) for peripheral SBP, 0.76 (0.63-0.89) for peripheral DBP, 1.02 (0.87-1.17) for central systolic pressure and 0.26 (0.16-0.37) for central pulse pressure. The associations were generally stronger in Chinese women (P-interaction = 0.03 for central pulse pressure) and individuals with gestational diabetes (P-interaction = 0.03 for DBP and P-interaction = 0.046 for central systolic pressure). Similar patterns of results were found when using skinfold thickness as the measure of adiposity.. Maternal adiposity is associated with higher peripheral and central blood pressures during pregnancy. Stronger associations in Chinese women and individuals with gestational diabetes warrant further investigation.

Recent studies revealed a possible reciprocal relationship between the skeletal system and obesity and lipid metabolism, mediated by osteocalcin, an osteoblast-specific protein. This study aimed to validate the relationship between serum osteocalcin and indices of obesity and lipid parameters in a group of Malaysian men.. A total of 373 men from the Malaysian Aging Male Study were included in the analysis. Data on subjects' demography, body mass index (BMI), body fat (BF) mass, waist circumference (WC), serum osteocalcin and fasting lipid levels were collected. Bioelectrical impendence (BIA) method was used to estimate BF. Multiple linear and binary logistic regression analyses were performed to analyze the association between serum osteocalcin and the aforementioned variables, with adjustment for age, ethnicity and BMI.. Multiple regression results indicated that weight, BMI, BF mass, BF %, WC were significantly and negatively associated with serum osteocalcin (p < 0.001). There was a significant positive association between serum osteocalcin and high density lipoprotein (HDL) cholesterol (p = 0.032). Binary logistic results indicated that subjects with low serum osteocalcin level were more likely to be associated with high BMI (obese and overweight), high BF%, high WC and low HDL cholesterol (p < 0.05). Subjects with high osteocalcin level also demonstrated high total cholesterol level (p < 0.05) but this association was probably driven by high HDL level. These variables were not associated with serum C-terminal of telopeptide crosslinks in the subjects (p > 0.05).. Serum osteocalcin is associated with indices of obesity and HDL level in men. These relationships should be validated by a longitudinal study, with comprehensive hormone profile testing.

This study aimed to provide an overview of lifestyle changes after breast cancer diagnosis and to examine the relationship between dietary and physical activity changes with weight changes in breast cancer patients. Women with breast carcinomas (n=368) were recruited from eight hospitals and four breast cancer support groups in peninsular Malaysia. Dietary and physical activity changes were measured from a year preceding breast cancer diagnosis to study entry. Mean duration since diagnosis was 4.86±3.46 years. Dietary changes showed that majority of the respondents had decreased their intake of high fat foods (18.8-65.5%), added fat foods (28.3-48.9%), low fat foods (46.8-80.7%), red meat (39.7%), pork and poultry (20.1-39.7%) and high sugar foods (42.1-60.9%) but increased their intake of fish (42.7%), fruits and vegetables (62.8%) and whole grains (28.5%). Intake of other food groups remained unchanged. Only a small percentage of the women (22.6%) had increased their physical activity since diagnosis where most of them (16.0%) had increased recreational activities. Age at diagnosis (β= -0.20, p= 0.001), and change in whole grain (β= -0.15, p= 0.003) and fish intakes (β= 0.13, p= 0.013) were associated with weight changes after breast cancer diagnosis. In summary, the majority of the women with breast cancer had changed their diets to a healthier one. However, many did not increase their physical activity levels which could improve their health and lower risk of breast cancer recurrence.

The prevalence of overweight and obesity among adolescents is rising rapidly in many countries, including Malaysia. This article aims to present the associations between body mass index-based body weight status, body weight perception, and weight control practices among adolescents in Malaysia. The Malaysia School Based Nutrition Survey 2012, which included a body weight perception questionnaire and anthropometric measurements, was conducted on a representative sample of 40 011 students from Standard 4 until Form 5, with a 90.5% response rate. Comparing actual and perceived body weight status, the findings show that 13.8% of adolescents underestimated their weight, 35.0% overestimated, and 51.2% correctly judged their own weight. Significantly more normal weight girls felt they were overweight, whereas significantly more overweight boys perceived themselves as underweight. The overall appropriateness of weight control practices to body weight was 72.6%. Adolescents attempting to lose or gain weight need to have better understanding toward desirable behavioral changes.

Acne is a common skin disorder which can cause physical scaring and impact the quality of life. The aim of this study is to determine the prevalence, severity and the risk factors for developing acne among medical students in Universiti Kebangsaan Malaysia (UKM).. A cross sectional study among UKM medical students from academic year 1 to 5 was conducted from July 2011 to May 2012. A total of 361 students were selected by stratified cluster sampling method. Baseline data of the students, risk factors, height and weight were recorded. Acne severity was graded using the Comprehensive Acne Severity Scale (CASS).. The prevalence of acne among medical students is 68.1% (n=246). Males and females were almost equally affected (1:1.1). Majority students with acne were graded as almost clear (55.7%, n=137), mild (35.0%, n=86), moderate (7.7%, n=19), and severe (1.6%, n=4). More than half of them had developed acne scars (59.0%, n= 213). Males were found to be at higher risk of developing acne compared to females (p<0.05, OR=4.734; 95%CL=2.726-8.222). They are also at higher risk of developing moderate and severe grades of acne compared to females (p=0.001). The odds for developing acne was higher when mother (p=0.029; OR=1.752; 95%CL=1.058-2.902) or father (p=0.027; OR=1.852; 95%CL=1.072-3.201) had acne. When both parents were affected by acne the odds of developing acne was 3 times. (p=0.025; OR=3.056; 95%CL=1.153-8.094).. This study shows that the prevalence of acne among medical students is high. Hence, it is important to identify those at risk and provide optimal treatment to prevent scarring and possible low self esteem among these future doctors.

This study aimed to identify the prevalence of energy misreporting amongst a sample of Malay children aged 9-11 years (n = 14) using a range of commonly used cut points. Participants were interviewed using repeated 24 h dietary recalls over three occasions. The Goldberg equations (1991 and 2000), Torun cut points and the Black and Cole method were applied to the data. Up to 11 of 14 children were classified as misreporters, with more under-reporters (between seven and eight children) than over-reporters (four or less children). There were significant differences in the proportion of children classified as energy misreporters when applying basal metabolic rate calculated using FAO/UNU/WHO (1985) and Malaysian-specific equations (p < 0.05). The results show that energy misreporting is common amongst Malay children, varying according to cut point chosen. Objective evaluation of total energy expenditure would help identify which cut point is appropriate for use in Malay paediatric populations.

The aim or this study was to determine factors associated with body weight status among Iranian adolescents in the two Secondary Schools run by the Embassy in Kuala Lumpur.. A self administered questionnaire was used to assess socio demographic characteristics, physical activity, and body image. Dietary intake was recorded through individual interviews with the researcher. The Physical Activity Questionnaire for children (PAQ-C) was used to evaluate levels of physical activity of the adolescents.. One-third (32.2%) of respondents were of normal weight, 14.5% and 11.1% were overweight and obese respectively, while 18.6% and 23.6% were severe thinness and thinness respectively. While the distribution of obese respondents by gender was almost the same, overweight females (16.4%) exceeded overweight males (12.7%) and although more females were in the thinness category (24.7% compared to 22.7%), more males were severely thin (20.0%) compared to 17.1% of the females. Body weight status was significantly associated with age (p < 0.05), gender (p < 0.05) and grade (p < 0.05). Males had significantly higher physically activity scores than females (p < 0.05). Intake of all micronutrients were higher than Dietary Reference Intake (DRI), except for vitamins B1, B2, C, D and E, Folate, Zinc, Magnesium, Potassium, Calcium and Phosphorus. There was a tendency for the females to overestimate their weight and 72.6% of them expressed their desire to lose weight while 60% of the males wanted to gain weight. There was also significant association between body weight status and perception of ideal body size (p = 0.000) and healthy body size (p = 0.000).. This study provides some information for the Iranian Secondary school to design intervention programs to improve the body weight status of their students.

Clinical practice guidelines recommend objective nutritional assessments in managing chronic kidney disease (CKD) patients but were developed while referencing to a North-American population. Specific recommendations for assessing muscle mass were suggested (mid-arm circumference, MAC; corrected mid-arm muscle area, cAMA; mid-arm muscle circumference, MAMC). This study aimed to assess correlation and association of these assessments with dietary protein intake in a multi-ethnic Asian population of healthy and CKD patients.. We analyzed 24-hour urine collections of selected participants to estimate total protein intake (TPI; g/day). Ideal body weight (IDW; kg) was calculated and muscle assessments conducted. Analyses involved correlation and linear regression, taking significance at p<0.05.. There were 232 stable CKD patients and 103 healthy participants comprising of 51.0% male, 38.5% Chinese, 29.6% Malay, 23.6% Indian, and 8.4% others. The mean TPI was 58.9 ± 18.4 g/day in healthy participants and 53.6 ± 19.4 g/day in CKD patients. When normalized to ideal body weight, TPI-IDW (g/kg/day) was similar in healthy and CKD participants. Overall, TPI was associated with MAC (r=0.372, p<0.001), cAMA (r=0.337, p<0.001), and MAMC (r=0.351, p<0.001). TPI-IDW was also associated with MAC (r=0.304, p<0.001), cAMA (r=0.202, p<0.001), and MAMC (r=0.200, p<0.001) but not for TPI normalized to actual body weight. When examined separately, TPI was associated with MAC, cAMA, and MAMC in both CKD and healthy participants, but was associated with TPI-IDW only in CKD patients.. Total protein intake was associated with muscle assessments in all participants. TPI normalized to IDW should only be used in CKD patients.. 背景：在慢性肾脏病患者的管理中，临床实践指南推荐的客观营养评估是参 考北美人群开发的。具体的肌肉质量评估建议如下：中臂围（MAC）、校正 的中臂肌肉面积（cAMA）和中臂肌围（MAMC）。本研究的目的是在多民族 亚裔人群中评估健康人和慢性肾脏病患者肌肉质量与膳食蛋白质摄入量之间的 关系。方法：我们分析了所收集的参与者24 小时尿来估算总蛋白质摄入量 （TPI，克/天）。计算理想体重（IDW，千克）并评估肌肉。应用相关性和线 性回归分析，显著性定义为p<0.05。结果：共有232 名稳定的慢性肾脏病患 者和103 名健康志愿者参加，其平均年龄为53.5±15.1 岁， 51.0%为男性，其 中华人占38.5%、马来人占29.6%、印度人占23.6%、其他民族的人占8.4%。 健康志愿者和慢性肾脏病患者的TPI 分别为58.9±18.4 克/天和53.6±19.4 克/ 天。当标准化为理想体重，健康志愿者和慢性肾脏病患者的TPI-IDW（克/千 克/日）相似。总体来看，TPI 与MAC、cAMA 和MAMC 相关，相关系数分 别为：0.372、0.337 和0.351（p<0.001)。TPI-IDW 也与MAC、cAMA 和 MAMC 相关，相关系数分别为：0.304、0.202 和0.200（p<0.001），但是TPI 标准化为实际体重与这些肌肉质量评估参数没有相关性。当单独分析时， MAC、cAMA 和MAMC 与健康志愿者和慢性肾脏病患者的TPI 都有关，但只 与慢性肾脏病患者的TPI-IDW 有关。结论：总蛋白质摄入量与所有参与者的 肌肉评估有关，TPI 标准化为理想体重只适用于慢性肾脏病患者。

Childhood obesity is related to low physical activity level and a sedentary lifestyle. The aim of this study was to assess the physical activity level and sedentary behaviour of Malaysian children aged 7 to 12 years and to examine their association with body mass index (BMI), BMI-for-age Z-score (BAZ), body fatness (%BF) and waist circumference (WC). A total of 1736 children, representing all ethnic groups were recruited from six regions of Malaysia. Anthropometric measurements included body weight, height and waist circumference. Body fat percentage (%BF) was assessed using bioelectrical impedance. Physical activity was assessed by a physical activity questionnaire (PAQ) in all children and by pedometers in a subsample (n = 514). PAQ score and pedometer step counts were negatively associated with BMI, BAZ, %BF and WC after adjusting for covariates. Screen time was positively associated with BAZ and WC. However, other sedentary activities were not significantly related with any anthropometric indicators. Strategies to promote active living among children in Malaysia should focus not only on increasing physical activity but also emphasise reduction in sedentary behaviours.

Early onset of menarche has been shown to be associated with breast cancer and ischaemic heart disease. Studies on age at menarche of the Malaysian population are poorly documented. This study aimed to determine the influence of anthropometric and socio-demographic factors on the age at menarche of university students in Malaysia. Data were obtained in 2010-11 from 961 students between the ages of 18 and 25 years from the University of Malaya using stratified sampling, and multiple regression analysis was applied. Sixty-three per cent of students reached menarche at the age of 12 or 13 years, with the mean and median of age at menarche being 12.45 ± 1.17 and 12.01 years, respectively. Menarcheal age was positively associated with height (p<0.05) and negatively associated with BMI (p<0.001). Students from urban areas attained menarche earlier than those from rural areas (p<0.05). Students from small-sized families attained menarche earlier than those from larger families (p<0.05). First-born students experienced menarche earlier than those who were seventh-born or later. Obese and overweight students reached menarche earlier than students who were underweight or of normal weight (p<0.01). The variations in age at menarche among the Malaysian ethnic groups were statistically insignificant. The results suggest that heavier and first-born students from small families are more likely to attain menarche earlier than their counterparts.

Physical inactivity has been acknowledged as a public health issue and has received increasing attention in recent years. This cross-sectional study was conducted to determine the barriers to physical activity among Malaysian men. These barriers were analyzed with regards to sociodemographic factors, physical activity level, BMI and waist circumference.. Subjects in this study included 308 Malay men and 422 Chinese men aged 20 years and older. Subjects completed the International Physical Activity Questionnaire (IPAQ) and a questionnaire on barriers to physical activity, categorized into personal and psychological, physical and social environment barriers. Weight, height and waist circumference were also measured and BMI was calculated.. Descriptive analyses showed that 79.3% of subjects were married, 52.1% had secondary educational level, 68.8% were still working, and 39.7% had household income between RM1500 to RM3500. The perception that other recreational activities with family and friends were more fun was the most frequently reported barrier, followed by weather, lack of discipline, lack of free time, lack of money, and lack of friends. Marriage status, educational level, household income, BMI, and physical activity status were shown to be associated with perceived barriers.. To increase participation in physical activity, policy makers should consider significant personal, social and environmental barriers when developing appropriate intervention programmes. Health-promoting strategies that increase awareness, knowledge, skills and motivation related to physical activity are required.

The dual burden of malnutrition reportedly coexists in Malaysia; however, existing data are scarce and do not adequately represent the nutritional status of Malaysian children. The Nutrition Survey of Malaysian Children was carried out with the aim of assessing the nutritional status in a sample of nationally representative population of children aged 6 months to 12 years. A total of 3542 children were recruited using a stratified random sampling method. Anthropometric measurements included weight, height, mid-upper arm circumference, and waist and hip circumferences. Blood biochemical assessment involved analyses of Hb, serum ferritin, and vitamins A and D. Dietary intake was assessed using semi-quantitative FFQ, and nutrient intakes were compared with the Malaysian Recommended Nutrient Intakes (RNI). The prevalence of overweight (9·8%) and obesity (11·8%) was higher than that of thinness (5·4%) and stunting (8·4%). Only a small proportion of children had low levels of Hb (6·6%), serum ferritin (4·4%) and vitamin A (4·4%), but almost half the children (47·5%) had vitamin D insufficiency. Dietary intake of the children was not compatible with the recommendations, where more than one-third did not achieve the Malaysian RNI for energy, Ca and vitamin D. The present study revealed that overnutrition was more prevalent than undernutrition. The presence of high prevalence of vitamin D insufficiency and the inadequate intake of Ca and vitamin D are of concern. Hence, strategies for improving the nutritional status of Malaysian children need to consider both sides of malnutrition and also put emphasis on approaches for the prevention of overweight and obesity as well as vitamin D insufficiency.

The influence of nutritional parameters and genetic susceptibility on poor cognitive impairment has been documented; however, the association between lipid-soluble vitamins with genetic susceptibility on mild cognitive impairment (MCI) has not yet been studied extensively.. The aim of the present study was (i) to determine the prevalence of MCI and its associated risk factors and (2) to investigate the influence of the apolipoprotein E (APOE) ε4 allele on peripheral vitamin A and E concentration in MCI and non-MCI groups.. A total of 333 subjects aged 60 years and above, residing in public housing areas in Kuala Lumpur, Malaysia were interviewed to obtain information on their neuropsychological status. Fasting venous blood was taken for determination of vitamin A and vitamin E concentration using high-performance liquid chromatography. Restriction fragment length polymorphism analysis was performed to determine the APOE genotypes.. The prevalence of MCI was 21.1%. Binary logistic regression indicated that the predictors of MCI were being married, overweight or obesity, and had vitamin A deficiency. In non-MCI subjects, vitamin E levels were lower among APOEε4 allele carriers as compared to the non-carriers (P < 0.05).. The study highlighted the importance of maintaining good nutritional status and vitamin A status for optimal cognitive function. The presence of APOEε4 allele has a prominent role in affecting vitamin E levels, particularly among cognitively healthy elderly in our unique population.

The increasing prevalence of overweight and obesity among children has become a major public health problem in Malaysia. Parents play an important role in child feeding especially among younger children.. A study was conducted to evaluate the beliefs, attitudes and practices in child feeding among parents of normal weight, as well as overweight and obese primary school children in Kelantan using the Child Feeding Questionnaire (CFQ). This cross-sectional study was carried out on 175 Malay children from three schools in Kota Bharu district in Kelantan.. This study showed that 13.1% of the children were overweight and obese. Scores for perceived parent weight (p < 0.05) and perceived child weight (p < 0.001) were significantly higher among parents of overweight and obese children compared to parents of children with normal body weight. However, the score for pressure to eat among parents of overweight and obese children was significantly lower (p < 0.05) than parents of normal weight children. The perceived child weight (r = 0.468, p < 0.01), perceived parental weight (r = 0.190, p < 0.05) and food restriction (r = 0.179, p < 0.05) factors were found to be positively correlated with children's body mass index (BMI), whereas pressure to eat factor (r = -0.355, p < 0.01) was negatively correlated with children's body mass index (BMI).. The findings showed that parental feeding practices were linked to children's weight status and childhood obesity. Therefore parents should be given education and guidance on appropriate child feeding practices to maintain their child's nutritional status on a healthy weight range.

Body weight of children is affected by many factors including food habits which are influenced by their parents. Studies in the West have shown that parents tend to control child feeding in response to their child's weight status. The aim of this study was to assess Malaysian parental concerns about child weight and the control they exert on child feeding.. This cross-sectional study was conducted on parents and their children aged 9 to 12 years from a primary school in Kuala Lumpur. The weight status of the children was classified according to the body mass index-for-age growth chart. Parental concerns about child weight and control in child feeding was assessed using the adapted Malay version of Child Feeding Questionnaire.. A total of 204 parents participated in this study. The study found that being a female served as a protective factor against becoming overweight (OR: 0.28, CI: 0.13-0.62). Parents with overweight children were significantly older (OR: 1.08, CI: 1.01-1.15), concerned about their child's weight (OR: 2.77, CI: 1.49-5.12) and controlled their child's feeding by restricting food intake (OR: 2.70, CI: 1.30-5.60). They were less likely to pressure their children to eat (OR: 0.32, CI: 0.19-0.56). Parents from the low income group were more likely to have underweight children (OR: 4.15, CI: 1.28-13.47).. There was significant difference in level of parental concern across differing child weight status. Parents with overweight children were likely to be more concerned about their child's weight, tending to control their feeding. In contrast, parents with underweight children did not exert control on their feeding.

A cross-sectional study was carried out to investigate accelerometer-determined physical activity level of 233 Malay government employees (104 men, 129 women) working in the Federal Government Building Penang, Malaysia.. Body weight, height, waist and hip circumference, body fat percentage and blood pressure were measured for each respondent. All the respondents were asked to wear an accelerometer for 3 days. Body mass index (BMI) and waist-hip ratio (WHR) were calculated using a standard formulas. Fasting blood sample was obtained to determine the lipid profile and glucose levels of the respondents.. Based on the accelerometer-determined physical activity level, almost 65% of the respondents were categorised as sedentary. Approximately 50.2% of the respondents were overweight or obese. There were negative but significant relationships between body mass index (BMI) (r = -0.353, p < 0.05), body fat percentage (r = -0.394, p < 0.05), waist circumference (WC) (r = -0.198, p < 0.05) and physical activity level. Sedentary individuals had a higher risk than moderate to active individuals of having a BMI more than or equal to 25 kg/m2 (OR = 2.80, 95% CI 1.55-5.05), an-risk classified WC (OR = 1.79, 95% CI 1.01-3.20), and a body fat percentage classified as unhealthy (OR = 3.01, 95% CI 1.41-6.44).. The results of this study suggest that accelerometer-determined physical activity level is a significant factor associated with obesity in this study. The high prevalence of physical inactivity and obesity found among respondents of this study indicate a need for implementing intervention programmes among this population.

Blue swimming crab, Portunus pelagicus is widely study and research throughout the Indo-West Pacific, but little is known of its reproductive biology in Malaysia. The present study describes the fecundity, embryonic development and ovarian development stages of the P. pelagicus from Johor coastal water, Malaysia. Carapace width range of berried crabs sampled was from 9.64 to 13.32 cm, while the body weight range was from 75 to 235 g. The mean number of egg produced by females in different sizes ranged from 105443.333 +/- 35448.075 per eggs batch. Mean egg size during embryonic development at stage 1 was 0.307 +/- 0.037, while 0.386 +/- 0.039 and 0.396 +/- 0.033 for stage 2 and stage 3, respectively. Study showed that there was significant (p < 0.05) relationship between the number of eggs and carapace width/body weight. Mean diameter oocyte during ovarian development at stage 1 was 97.732 +/- 12.391 while for stage 2 was 149.516 +/- 23.287. Stage 3 showed increasingly of size with mean diameter was 158.506 +/- 27.616 and 181.013 +/- 24.339 for stage 4.

There is a pressing need to better understand the complex biochemical pathways that lead to the pathogenesis of obesity. Increased oxidative stress and decreased antioxidant capacity have been identified to be associated with obesity. Therefore, the objectives of this study were to determine the plasma total antioxidant capacity (TAC) levels of Malaysian subjects and to evaluate its potential association with obesity and related anthropometric measurements.. Plasma TAC of 362 multi-ethnic Malaysian subjects from the Kampar Health Clinic (138 males, 224 females; 124 ethnic Malays, 152 Chinese, 86 Indians; 192 non-obese, 170 obese) was measured using Trolox equivalent antioxidant capacity (TEAC) 96-well plate assay.. Plasma TAC was significantly lower in obese subjects (M +/- SE = 292 +/- 10.4 micromol/L) compared to non-obese subjects (397 +/- 8.58 micromol/L), whereas it was significantly higher in males and those in the 21-30 age group. Those with salty food preference and practising a strict vegetarian diet also had significantly higher plasma TAC. However, no association was found for other dietary habits (coffee intake) and lifestyle factors (physical activity, smoking). Plasma TAC was also significantly negatively correlated with diastolic blood pressure, waist and hip circumferences, weight, body mass index, total body fat, % subcutaneous fat, visceral fat level, resting metabolism and % skeletal muscle.. Plasma TAC was found to be associated with obesity, strict vegetarian practice, salty food preference and all obesity anthropometric indicators, except systolic blood pressure and pulse rate. Obese people have decreased plasma TAC indicating a compromised systemic antioxidant defence and increased oxidative stress.

This study aimed to develop demi-span equations for predicting height in the Malaysian elderly and to explore the applicability of previous published demi-span equations derived from adult populations to the elderly.. A cross-sectional study was conducted on Malaysian elderly aged 60 years and older. Subjects were residents of eight shelter homes in Peninsular Malaysia; 204 men and 124 women of Malay, Chinese and Indian ethnicity were included. Measurements of weight, height and demi-span were obtained using standard procedures. Statistical analyses were performed using SPSS version 18.0.. The demi-span equations obtained were as follows: Men: Height (cm) = 67.51 + (1.29 x demi-span) - (0.12 x age) + 4.13; Women: Height (cm) = 67.51 + (1.29 x demi-span) - (0.12 x age). Height predicted from these new equations demonstrated good agreement with measured height and no significant differences were found between the mean values of predicted and measured heights in either gender (p>0.05). However, the heights predicted from previous published adult-derived demi-span equations failed to yield good agreement with the measured height of the elderly; significant over-estimation and underestimation of heights tended to occur (p>0.05).. The new demi-span equations allow prediction of height with sufficient accuracy in the Malaysian elderly. However, further validation on other elderly samples is needed. Also, we recommend caution when using adult-derived demi-span equations to predict height in elderly people.

Nutritional decline is typically accepted as a consequent of the course of treatment for cancer. This study aimed to (1) assess body weight status and dietary intake of breast cancer patients on chemotherapy and (2) to correlate Body Mass Index (BMI), energy and protein intake with health-related quality of life (HRQoL) profile.. A cross-sectional study was conducted in two government hospitals in the East coast of Peninsular Malaysia using convenience sampling. Women aged > or =18 years, who were diagnosed with breast cancer and receiving chemotherapy were invited to participate. The following aspects were evaluated: body weight status, usual dietary intake (diet history) and HRQoL (EORTC QLQ-C30). Descriptive statistics and non-parametric tests were employed (SPSS 16).. Of the respondents, 41 were 49 +/- 9.6 years of age; 92.7% were Malay; 97.6% (response rate = 91%) were on moderately emetogenic chemotherapy. Over half of the patients were overweight or obese (mean BMI = 25.3 +/- 1.1 kg/m2). The majority self-reported weight reduction (46.3%) but positive energy balance was detected with the current energy and protein intakes recorded at 1792.6 +/- 304.9 kcal/day (range= 1200-2500) and 74.5 g/day (IqR= 37.7) respectively. Dietary intakes were, however, not correlated with HRQoL, but greater BMI was associated with better emotional and cognitive functioning and less fatigue.. Although most patients declared losing weight, obesity and excess dietary intake were noted. Additionally, body weight status has been shown to be important in HRQoL profile, underlining the necessity for effective nutritional assessments and support to the cancer population.

The aim of this study was to evaluate the effect of different doses of Malaysian honey on male reproductive parameters in adult rats. Thirty-two healthy adult male Sprague-Dawley rats were randomly divided into four groups (eight rats per group). Group 1 (control group) was given 0.5 ml of distilled water. Groups 2, 3 and 4 were given 0.2, 1.2 and 2.4 g kg(-1) body weight of honey respectively. The rats were treated orally by gavage once daily for 4 weeks. Honey did not significantly alter body and male reproductive organs weights. The rats in Group 3 which received honey at 1.2 g kg(-1) had significantly higher epididymal sperm count than those in Groups 1, 2 and 4. No significant differences were found for the percentage of abnormal sperm, elongated spermatid count, reproductive hormonal levels as well as the histology of the testis among the groups. In conclusion, Malaysian honey at a dose of 1.2 g kg(-1) daily significantly increased epididymal sperm count without affecting spermatid count and reproductive hormones. These findings might suggest that oral administration of honey at this dose for 4 weeks may enhance spermiogenesis in adult rats.

This study is focused on evaluating the trace metal levels in water and tissues of two commercial fish species Arius thalassinus and Pennahia anea that were collected from Kapar and Mersing coastal waters. The concentrations of Fe, Zn, Al, As, Cd and Pb in these coastal waters and muscle, liver and gills tissues of the fishes were quantified. The relationship among the metal concentrations and the height and weight of the two species were also examined. Generally, the iron has the highest concentrations in both water and the fish species. However, Cd in both coastal waters showed high levels exceeding the international standards. The metal level concentration in the sample fishes are in the descending order livers > gills > muscles. A positive association between the trace metal concentrations and weight and length of the sample fishes was investigated. Fortunately the level of these metal concentrations in fish has not exceeded the permitted level of Malaysian and international standards.

A Boer goat breeding farm with 800 heads of breeder females, 50 breeder males, and 400 growing goats of various ages in Sabah, Malaysia was selected to study the effect of implementing herd health program. This included vaccination program against pneumonic mannheimiosis; fecal monitoring for helminthiasis, coccidiosis, and colibacillosis; and introduction of modified feeding regime comprised of day-time grazing and feeding of cut grass and supplemented feed. The herd health program was implemented in September 2007 and the impact was observed on body weight gains, body scoring, and annual mortality among adults and kids. It was found that implementation of herd health program significantly (p < 0.05) increased the average body weight gains in both adults and kids from 1.8 g per kid and 0.6 g per adult in 2006 to 3.7 g per kid and 2.2 g per adult in 2008. The percentage of adults with body scoring of <3 was significantly (p < 0.05) reduced from 82.3% in 2006 to 77.6% in 2007 and 4% in 2008. Similarly, the annual mortality rate was significantly (p < 0.05) reduced from 6.5% among kids and 58.2% among adults in 2006 to 12.1% among kids and 10.4% among adults in 2007, and to 9.1% among kids and 1.1% among adults in 2008. Therefore, it was concluded that implementation of herd health program significantly improved the survival and performance of goats.

This study aimed to determine the relationship between child feeding practices, food habits, and anthropometric indicators with cognitive performance of preschoolers aged 4-6 years in Peninsular Malaysia (n=1933). Parents were interviewed on socio-demographic background, nutrition knowledge, child feeding practices and food habits. Height and weight of the preschoolers were measured; BMI-for-age, weight-for-age and height-for-age were determined. Cognitive performance was assessed using Raven's Colored Progressive Matrices. The mean monthly household income was RM3610 and 59.6% of parents attained secondary education. Thirty-three percent of parents had good knowledge on nutrition, 39% satisfactory and 28% poor. For child feeding practices, perceived responsibility had the highest mean score (M=3.99, SD=0.72), while perceived child weight had the lowest (M=2.94, SD=0.38). The prevalence of possible risk of overweight, being overweight, and obesity were 3.9%, 7.9% and 8.1%, respectively, whereas the prevalence of underweight and stunting were 8.0% and 8.4%, respectively. Breakfast was the second most frequently skipped meal (16.8%) after dinner (18.1%). The mean cognitive score was 103.5 (SD=14.4). Height-for-age and consumption of dinner were found to contribute significantly towards cognitive performance after controlling for socio-demographic background and parent's nutrition knowledge.

The mechanism linking biopsychosocial factors to disordered eating among university students is not well understood especially among Malaysians. This study aimed to examine the mediating role of psychological distress in the relationships between biopsychosocial factors and disordered eating among Malaysian university students. A self-administered questionnaire measured self-esteem, body image, social pressures to be thin, weight-related teasing, psychological distress, and disordered eating in 584 university students (59.4% females and 40.6% males). Body weight and height were measured. Structural equation modeling analysis revealed that the partial mediation model provided good fit to the data. Specifically, the relationships between self-esteem and weight-related teasing with disordered eating were mediated by psychological distress. In contrast, only direct relationships between body weight status, body image, and social pressures to be thin with disordered eating were found and were not mediated by psychological distress. Furthermore, multigroup analyses indicated that the model was equivalent for both genders but not for ethnic groups. There was a negative relationship between body weight status and psychological distress for Chinese students, whereas this was not the case among Malay students. Intervention and prevention programs on psychological distress may be beneficial in reducing disordered eating among Malaysian university students.

This study aimed to measure the basal metabolic rate (BMR) of elite athletes and develop a gender specific predictive equation to estimate their energy requirements.. 92 men and 33 women (aged 18-31 years) from 15 sports, who had been training six hours daily for at least one year, were included in the study. Body composition was measured using the bioimpedance technique, and BMR by indirect calorimetry. The differences between measured and estimated BMR using various predictive equations were calculated. The novel equation derived from stepwise multiple regression was evaluated using Bland and Altman analysis.. The predictive equations of Cunningham and the Food and Agriculture Organization/World Health Organization/United Nations University either over- or underestimated the measured BMR by up to ± 6%, while the equations of Ismail et al, developed from the local non-athletic population, underestimated the measured BMR by 14%. The novel predictive equation for the BMR of athletes was BMR (kcal/day) = 669 + 13 (weight in kg) + 192 (gender: 1 for men and 0 for women) (R2 0.548; standard error of estimates 163 kcal). Predicted BMRs of elite athletes by this equation were within 1.2% ± 9.5% of the measured BMR values.. The novel predictive equation presented in this study can be used to calculate BMR for adult Malaysian elite athletes. Further studies may be required to validate its predictive capabilities for other sports, nationalities and age groups.

Jering (Archidendron jiringa) is eaten in the tropics and traditionally extolled for treating diabetes, high blood pressure and eliminating bladder stones. Jering contains an unusual amino acid-djenkolic acid (S,S'-methylenebiscysteine)-which may form sharp crystals in the urinary tract, causing pain and haematuria. This study evaluates the beneficial and toxic effects of dietary jering on tissues and organs in normal and diabetic rats.. Dietary jering administered orally to diabetic rats significantly reduced the blood glucose in the streptozotocin-induced diabetic rats to normal levels after about 12 weeks. Jering improved the rats' appetite, body weight, organ oxidative status and number of active islets of Langerhans in both diabetic and normal rats, after 15 weeks of treatment. Although dietary jering showed beneficial effects to diabetic eye lens, lung and pancreas, it caused hypertrophy and lesions to the heart, kidney, liver, lung and pancreas of normal rats.. Chronic jering consumption showed toxic effects to the heart, kidney, liver and pancreas of normal rats but produced some beneficial effects to diabetic rats.

University students are potentially important targets for the promotion of healthy lifestyles as this may reduce the risks of lifestyle-related disorders later in life. This cross-sectional study examined differences in eating behaviours, dietary intake, weight status, and body composition between male and female university students.. A total of 584 students (59.4% females and 40.6% males) aged 20.6 +/- 1.4 years from four Malaysian universities in the Klang Valley participated in this study. Participants completed the Eating Behaviours Questionnaire and two-day 24-hour dietary recall. Body weight, height, waist circumference and percentage of body fat were measured.. About 14.3% of males and 22.4% of females were underweight, while 14.0% of males and 12.3% of females were overweight and obese. A majority of the participants (73.8% males and 74.6% females) skipped at least one meal daily in the past seven days. Breakfast was the most frequently skipped meal. Both males and females frequently snacked during morning tea time. Fruits and biscuits were the most frequently consumed snack items. More than half of the participants did not meet the Malaysian Recommended Nutrient Intake (RNI) for energy, vitamin C, thiamine, riboflavin, niacin, iron (females only), and calcium. Significantly more males than females achieved the RNI levels for energy, protein and iron intakes.. This study highlights the presence of unhealthy eating behaviours, inadequate nutrient intake, and a high prevalence of underweight among university students. Energy and nutrient intakes differed between the sexes. Therefore, promoting healthy eating among young adults is crucial to achieve a healthy nutritional status.

A cross-sectional study was conducted to determine physical activity, eating behaviour, body weight management knowledge, perception of body image and their association with body weight status of adolescents.. Respondents were 360 adolescents, aged between 13 to 14 years, from six randomly selected secondary schools in Kuantan, Pahang. Physical activity, eating behaviour, body weight management knowledge and perception of body image were measured by the Physical Activity Questionnaire for Older Children (PAQ-C), Eating Attitude Test-26 (EAT-26), Weight Management Knowledge Inventory (WMKI) and Contour Drawing Rating Scale (CDRS), respectively.. Almost half of the respondents were categorised as having a normal BMI, while 30.3% were severely thin and thin and 20.3% were overweight and obese. Mean physical activity score was 2.06 +/- 0.45 with more males (35.0%) being physically active than females (17.3%). Mean eating behaviour score was 15.41 +/- 10.37, with 27.8% of the respondents being at-risk for eating disorders. Mean weight management knowledge score was 5.35 +/- 1.80, with more females (77.7%) having higher mean scores than males (42.3%). Further, mean discrepancy score for body image perception was 1.24 +/- 0.99, with 78.1% of the respondents being dissatisfied with their current body size. Positive associations were found between eating behaviour (r = 0.28, p < 0.05) and body image (r = 0.35, p < 0.05) with BMI. Respondents with high eating behaviour scores and body image discrepancy scores were more likely to have greater BMI.. This study shows the need for healthy eating and body image intervention programmes to prevent overweight and obesity problems among adolescents.

To test the null hypothesis that there is no difference in facial profile shape, malocclusion class, or palatal morphology in Malay adults with and without obstructive sleep apnea (OSA).. Subjects were 120 adult Malays aged 18 to 65 years (mean +/- standard deviation [SD], 33.2 +/- 13.31) divided into two groups of 60. Both groups underwent clinical examination and limited channel polysomnography (PSG). The mean OSA and control values were subjected to t-test and the chi square test.. Physical examination showed that 61.7% of the OSA patients were obese, and 41.7% of those obese patients had severe OSA. The mean body mass index (BMI) was significantly greater for the OSA group (33.2 kg/m2 +/- 6.5) than for the control group (22.7 kg/m2 +/- 3.5; P < .001). The mean neck size and systolic blood pressure were greater for the OSA group (43.6 cm +/- 6.02; 129.1 mm Hg +/- 17.55) than for the control group (35.6 cm +/- 3.52; 114.1 mm Hg +/- 13.67; P < .001). Clinical examination showed that the most frequent findings among OSA groups when compared with the control group were convex profiles (71.7%), Class II malocclusion (51.7%), and V palatal shape (53.3%), respectively; the chi square test revealed a significant difference in terms of facial profile and malocclusion class (P < .05), but no significant difference in palatal shape was found.. The null hypothesis is rejected. A convex facial profile and Class II malocclusion were significantly more common in the OSA group. The V palatal shape was a frequent finding in the OSA group.

The National Health and Morbidity Survey III 2006 wanted to perform anthropometric measurements (length and weight) for children in their survey. However there is limited literature on the reliability, technical error of measurement (TEM) and validity of these two measurements. This study assessed the above properties of length (LT) and weight (WT) measurements in 130 children age below two years, from the Hospital Universiti Kebangsaan Malaysia (HUKM) paediatric outpatient clinics, during the period of December 2005 to January 2006. Two trained nurses measured WT using Tanita digital infant scale model 1583, Japan (0.01kg) and Seca beam scale, Germany (0.01 kg) and LT using Seca measuring mat, Germany (0.1cm) and Sensormedics stadiometer model 2130 (0.1cm). Findings showed high inter and intra-examiner reliability using 'change in the mean' and 'intraclass correlation' (ICC) for WT and LT. However, LT was found to be less reliable using the 'Bland and Altman plot'. This was also true using Relative TEMs, where the TEM value of LT was slightly more than the acceptable limit. The test instruments were highly valid for WT using 'change in the mean' and 'ICC' but was less valid for LT measurement. In spite of this we concluded that, WT and LT measurements in children below two years old using the test instruments were reliable and valid for a community survey such as NHMS III within the limits of their error. We recommend that LT measurements be given special attention to improve its reliability and validity.

Body image concerns are common among adolescents as they undergo rapid physical growth and body shape changes. Having a distorted body image is a risk factor for the development of disordered eating behaviours and eating disorders. This study was undertaken to investigate body image concerns among Malaysian male and female adolescents aged 11-15 years.. A total of 2,050 adolescents (1,043 males and 1,007 females) with a mean age of 13.1 +/- 0.8 years from secondary schools in Kedah and Pulau Pinang were included in the study. Questionnaires were used to collect socioeconomic data and body image indicators.. The majority (87 percent) of the adolescents were concerned with their body shape. While the majority of underweight, normal weight and overweight male and female subjects perceived their body weight status correctly according to their body mass index (BMI), a noteworthy proportion in each category misjudged their body weight. About 35.4 percent of the males and 20.5 percent of the females in the underweight category perceived themselves as having a normal weight, while 29.4 percent and 26.7 percent of the overweight males and females respectively also perceived that they had a normal weight. A higher proportion of the females (20 percent) than males (9 percent) with a normal BMI perceived themselves as fat. Most of the male (78-83 percent) and female subjects (69-74 percent) in all the BMI categories desired to be taller than their current height. An appreciable proportion of both the males (41.9 percent) and females (38.2 percent) preferred to remain thin, or even to be thinner (23.7 percent of males and 5.9 percent of females). Females had a significantly higher mean body dissatisfaction score than males, indicating their preference for a slimmer body shape. More males (49.1 percent) preferred a larger body size while more females (58.3 percent) idealised a smaller body size. Compared to normal weight and underweight subjects, overweight males and females expressed lower confidence and acceptance levels, as well as expressed greater preoccupation with and anxiety over their body weight and shape.. As having a distorted body image may lead to negative effects such as unhealthy eating habits and disordered eating behaviours, it is recommended that appropriate educational efforts on body image be incorporated into school health activities for adolescents.

The Third National Health and Morbidity Survey Malaysia 2006 includes a nutritional status assessment of children. This study aimed to assess the inter- and intra-examiner reliability, the technical error of measurement and the validity of instruments for measuring weight, height and waist circumference.. A convenience sample of 130 adults working in a selected office setting was chosen to participate in the study, subject to the inclusion and exclusion study criteria. Two public health nurses, trained to follow a standard protocol, obtained the weight, height and waist circumference measurements. The weight was measured using the Tanita HD-318 digital weighing scale to the nearest 0.1 kg, and Seca Beam Scale to the nearest 0.01 kg. The height was measured using the Seca Bodymeter 206 and Stadiometer, both to the nearest 0.1 cm. The waist circumference was measured using the Seca circumference measuring tape S 201, to the nearest 0.1 cm.. The intra-examiner reliability in descending order was weight and height followed by waist circumference. The height measurement, on average, using the test instrument, reported a recording of 0.4 cm higher than the reference instrument, with the upper and lower limits at 2.5 cm and 1.6 cm, respectively. The technical error of measurement and coefficient of variation of weight and height for both inter-examiner and intra-examiner measurements were all within acceptable limits (below five percent).. The findings of this study suggest that weight, height and waist circumference measured in adults aged 18 years and above, using the respective above mentioned instruments, are reliable and valid for use in a community survey. Limiting the number of examiners, especially for waist circumference measurements, would yield a higher degree of reliability and validity.

Population growth, trophic level, and some aspects of reproductive biology of two congeneric archer fish species, Toxotes chatareus and Toxotes jaculatrix, collected from Johor coastal waters, Malaysia, were studied. Growth pattern by length-weight relationship (W=aL(b)) for the sexes differed, and exhibited positive allometric growth (male, female and combined sexes of T. chatareus; female and combined sexes of T. jaculatrix) and isometric growth (male samples of T. jaculatrix only). Trophic levels of both species were analyzed based on 128 specimens. The results show that, in both species, crustaceans and insects were the most abundant prey items, and among crustaceans the red clawed crab Sesarma bidens and Formicidae family insects were the most represented taxa. The estimated mean trophic levels for T. chatareus and T. jaculatrix were 3.422+/-0.009 and 3.420+/-0.020, respectively, indicating that they are largely carnivores. Fecundity of T. chatareus ranged from 38 354 to 147 185 eggs for females with total length ranging from 14.5 to 22.5 cm and total body weight from 48.7 to 270.2 g, and T. jaculatrix 25 251 to 150 456 eggs for females with total length ranging from 12.2 to 23.0 cm and total body weight from 25.7 to 275.0 g. Differences in values of gonadosomatic and hepatosomatic indexes calculated for both species in this study may have resulted from uneven sample size ranges.

This study aimed to determine the relationship between blood lead (BPb) concentrations and cognitive and physical development in school children. A total of 169 urban children and 100 industrial children of Malay ethnicity, in the age range of 6(1/2) to 8(1/2) years, were selected. BPb was determined using GF atomic absorption spectrophotometer. The mean cognitive score (102.55) of the children from the industrial area was significantly higher than that of the urban children (95.09; P < .001). However, no significant differences were found in the BPb levels between the 2 groups (industrial, 3.75 microg/dL; urban, 3.56 microg/dL). There was significant inverse correlation between BPb and cognitive scores for all children (P < .05). The cognitive scores for all children were influenced by BPb after adjustments (P < .05). The urban children had significantly better Weight for Height and Left Arm Circumference values than those from industrial area. There was no significant correlation between BPb and the anthropometric measurements. In conclusion, low BPb influenced the cognitive development, whereas physical development was not affected.

Ninety-six Malaysian and British men rated for physical attractiveness a set of photographs of real women in profile, with known body mass index (BMI) and waist-to-hip ratio (WHR). Results showed that BMI accounted for the greater amount of variance in all settings. There were also significant differences in preferences for body weight, with low resource, low socioeconomic status (SES) raters preferring a significantly heavier partner than high resource, high SES raters. The disparity with previous findings using line drawings of women in profile was discussed in terms of the weaknesses of line-drawn stimuli.

Comparisons of body attitudes and associated behaviours were undertaken using Malay, Samoan, and Australian female students. The general goal of the research was to determine the degree to which the observed pattern of attitudes and behaviours was attributable to culture. The specific analyses comprised an examination of group differences using standard measures that included the Body Attitudes Questionnaire, the Three-Factor Eating Questionnaire and detailed questions concerning the use of diet and exercise as weight control strategies. The main findings concerned a number of cultural differences, particularly in relation to diet and exercise, that were evident even with the effect of body mass index held constant. These results are interpreted in terms of the efficacy of entrenched cultural beliefs in protecting against introduced, more dominant, cultural values. The Australian sample exhibited the most negative body image, although there was some evidence that Malays and Samoans were influenced by Western ideals of weight and shape. It is proposed that to fully understand the differential meaning of negative body image across cultures and the potential impact of westernisation, both within-group and between-group differences in body size need to be acknowledged.

Feeding difficulties in cleft lip and palate (CLP) infants is commonly observed and is the most traumatic experience the family has to face. These infants are undernourished and have compromised growth. The purpose of this study was to 1) assess general health and growth parameters in children with CLP and in normal children; and 2) investigate the feeding methods of CLP infants and normal infants. A total of 221 children from birth to six years of both sexes, with CLP (60 children) and normal (161 children) were selected. The CLP and normal children were divided into three subgroups by age. The practice of feeding the infants in subgroup I was assessed using standard piloted questionnaires. The assessment of growth was done at baseline and at six months in all the subgroups.The general well being of the children was assessed by noting the number of common infections. Results showed that a significantly higher percentage of mothers with normal babies (p < 0.01) had a positive attitude towards breast feeding. When compared to normal children, CLP children were more susceptible to infections (p < 0.05) and measured significantly lower on the height growth curve(p < 0.05). Hence, height can be used to monitor growth in CLP children.

A total of 107 Malay primary school girls (8-9 yr. old) completed a set of measurements on eating behavior (ChEAT, food neophobia scales, and dieting experience), the Rosenberg Self-Esteem Scale, body shape satisfaction, dietary intake, weight, and height. About 38% of the girls scored 20 and more on the ChEAT, and 46% of them reported dieting by reducing sugar and sweets (73%), skipping meals (67%), reducing fat foods (60%) and snacks (53%) as the most frequent methods practiced. In general, those girls with higher ChEAT scores tended to have lower self-esteem (r=.39), indicating they were more unwilling to try new foods (food neophobic) (r=.29), chose a smaller figure for desired body size (r=-.25), and were more dissatisfied with their body size (r=.31).

Anthropometric and physiological profiles of national sepak takraw players were determined.. Thirty nine players, specialising in the three playing positions (tekong/server, feeder, and killer/spiker) were divided into three age categories of under 15 (U15), under 18 (U18), and under 23 (U23) years of age. Height, weight, percent body fat (%bf), maximum oxygen consumption (Vo(2max)), range of motion (ROM), back and leg strength, and heart rate, for the estimation of oxygen consumption during matches, were recorded. Statistical analysis was performed using one way ANOVA for independent measurements and data are presented as mean+/-standard deviation.. The U23 players were significantly taller and heavier with significantly better ROM of the neck, trunk, and ankle joints and back and leg strength than the U15 players. No significant difference was found in %bf between the three age categories. Mean maximum heart rate during exercise was significantly higher in the U15 group when compared to the U18 and U23 groups (p<0.05). Mean Vo2max was similar between the three groups. Estimated oxygen consumption during matches was 69.1%, 68.5%, and 56.4% of Vo2max in the killer, tekong, and the feeder groups, respectively.. The mean height, body weight, and cardiopulmonary capacities of the players were within the Malaysian population norms, but were somewhat lower than those of players of other court games from other countries. %bf was also lower in these players. This study provides the much needed anthropometric and physiological data of sepak takraw players for further development of this sport.

Long-term field studies were conducted on two government managed small ruminant research farms, located in different geo-climatic regions and approximately 300 km separate from each other, on Peninsula Malaysia. The Infoternak trial (48 weeks) and the Chalok trial (43 weeks) each compared nematode parasite control in separately managed groups of young sheep, either short-term rotationally grazed around a suite of 10 paddocks in addition to receiving a daily supplement of Duddingtonia flagrans spores (Fungus Group); or similar groups of sheep being rotationally grazed alone (Control Group). The prevailing weather conditions at Infoternak farm were of below average rainfall conditions for the most of the trial. As a consequence, only very low worm infections (almost exclusively Haemonchus contortus) were acquired by the 17 sets of tracer lambs that grazed sequentially with the experimental lambs. However on all except 2 occasions in the early part of the trial, the mean tracer worm burdens were significantly lower (P < 0.05) and the experimental lambs grew significantly better (P = 0.054) in the Fungus Group. Rainfall at Chalok farm during the course of the trial was also below average. As a consequence infectivity of pastures was assumed to be relatively low based on faecal egg counts (epg) of the experimental sheep, which following an anthelmintic treatment prior to allocation, remained very low in both treatment groups. Faecal egg counts of undosed replacement lambs in the latter half of the Chalok study, showed a progressive increase in the Control Group to levels exceeding 3000 epg, whereas the Fungus Group remained static at approximately 500 epg. These results show that the deployment of the nematophagous fungus, D. flagrans, can improve the level of parasite control of sheep in the tropics above that which can be achieved by the short-term rotational grazing strategy alone.

Ethnic differences in bone density and hip geometry are known to exist, even within the same population. A recent study in Singapore showed that there were significant racial differences in hip fracture rates, with Chinese having the highest incidence of hip fractures. The aim of this study was to compare the bone mineral density (BMD) and hip axis length in Chinese, Malay, and Indian women. A total of 1575 women aged 20-59 yr were recruited, of which 77.6% (1222) were Chinese, 7.7% (122) Malays, and 14.7% (231) Indians. There was no significant difference in peak BMD of both lumbar spine and femoral neck among the three ethnic groups. However, in the older age group (50-59 yr), both Chinese and Malay women had significantly lower femoral neck BMD compared to Indian women. There was no significant loss in BMD of the lumbar spine between the second and fifth decades in all the three races. Between the second and fifth decade, Chinese and Malay women had significant bone loss in the femoral neck of 6.6% and 8.2%, respectively, whereas Indian women did not show any significant bone loss. Chinese women had significantly longer hip axis length compared to either Malay or Indian women (9.87 +/- 0.52 cm vs 9.67 +/- 0.49 cm; p < 0.005; and 9.69 +/- 0.55 cm, p < 0.05, respectively). The initial findings suggest racial differences in bone density and hip geometry exist in the local community. Future research should include prospective, longitudinal studies to determine the age-related bone loss in these three racial groups. It is also important to investigate the differences of spine and hip fracture rates and their relationship with bone density and hip axis length.

This report is a part of a multi-centre study in Asia on the problem of dual forms of malnutrition in the same households. In Malaysia, the prevalence of underweight and stunting persist among young children from poor rural areas. Overweight in adults, especially women from poor rural areas has been reported in recent years. Thus, this study was undertaken in order to assess the presence of the dual burden of underweight child-overweight mother pairs in a poor rural community. Out of 140 Malay households identified to have at least one child aged 1-6 years and mother aged above 20 years, 52.1% of the mothers were overweight, 15.7% of the children were underweight, 27.1% stunted and 5% wasted. Socio-economic background and food intake frequency data were collected from 54 underweight child/overweight mother pairs (UW/OW) and 41 normal weight child/normal weight mother pairs (NW/NW). Compared with the overweight mothers, a higher percentage of the normal weight mothers had received secondary education, were employed and with a higher household monthly income, although these differences were not significant. Patterns of food intake of the mothers and children appeared to have more similarities than differences between the UW/OW and NW/NW groups. Quantitative dietary intakes for 2 days using 24-hr recall and physical activity energy expenditure over the same period were assessed in a sub-group of UW/OW and NW/NW mothers and children. The NW/NW children showed significantly higher intake of total calories, fat and riboflavin than the UW/OW counterparts. Mean energy and nutrient intake of mothers from both groups were not significantly different, although the NW/NW mothers showed higher intake adequacy for total calories and most nutrients. While most of the mothers from both groups reported having no chronic illnesses, about half of the children in both groups had infections, especially gastrointestinal infections, over a 2-week period. Energy expenditure from physical activity for both UW/OW and NW/NW mothers and children did not differ significantly. This study confirmed inadequate intake of total energy and nutrients as the major factor for underweight in Malay children from rural areas. However, assessing intake and physical activity by interview methods were not sensitive enough to overcome perceived problems of under-reporting of energy intake and over-estimation of energy expenditure, especially by overweight subjects.

To report on the anthropometric and growth status of children receiving renal replacement therapy (RRT) in Malaysia.. Cross-sectional study with some retrospective elements.. Outpatients' clinics in a major referral hospital in Malaysia.. Fifteen renal transplants (mean age, 13.3 +/- 2.8 years) and 35 continuous ambulatory peritoneal dialysis (CAPD) patients (mean age, 12.6 +/- 3.0 years) participated. The RRT period ranged between 3 months to 6 years for both groups.. None.. Body mass index (BMI), percent body fat (% BF), triceps skinfold (TSF), mid upper-arm circumference (MUAC), arm muscle area (AMA), and z scores for height and weight.. BMI for age indicated 7% of transplant subjects (TS) versus 40% of CAPD subjects were below the 5th percentile, whereas only 7% of TS were above the 95th percentile. % BF was higher for TS compared with the CAPD group for both sexes (boys, 19.5% and girls, 29.8% v boys, 12.4% and girls, 21.5%). Despite higher percentiles for TSF, transplant subjects still showed depleted muscle mass based on MUAC and AMA. z scores for height showed 93% of transplant subjects and 62% of CAPD subjects below -2 standard deviation (SD), whereas for weight these were 27% and 54%, respectively. Sixty-four percent of TS experienced catch-up growth for height and 86% for weight. These percentages were approximately halved for the CAPD group (32% and 43%, respectively).. Patterns of growth and body composition appear distinctly different with the different RRT modalities. Serial anthropometric evaluation appears vital in pre- and post-RRT monitoring in pediatric renal populations.

A total of 5,995 (7.8% of all 7- to 10-year-old primary schoolchildren in Kuala Lumpur), randomly selected from 166 schools (97.6% of all schools), were measured for their weight and height. The analyses of all weight and height data, including the cutoffs used for defining stunting, underweight, and wasting and for thinness and overweight, were carried out as recommended by the World Health Organization (WHO). The prevalances of stunting (height-for-age Z score < -2 SD), underweight (weight-for-age Z score < -2 SD) and wasting (weight-for-height Z score < -2 SD) among all the children studies were 6.7%, 7.1%, and 4.5%, respectively. Undernutrition among boys was more serious than among girls according to all three indicators. Because it was not possible to analyze the weight-for-height data for most of the children above 8.5 years of age, body mass index (BMI)-for-age was used to determine the prevalences of thinness and overweight for all the children. Based on the reference data, the prevalence of overweight (at or above the 95th percentile) was 9.7% and 7.1% for boys and girls, respectively, and 8.4% overall.

When standing height (StndHt) cannot be assessed, arm span (AS) or sitting height (SitHt) has been used as surrogate variables for prediction of StndHt in adult caucasians and blacks. We examined (1) the relationship between StndHt, AS and SitHt among adult Chinese, Malays and Indians; and (2) whether anthropometry could explain the ethnic differences in lung volumes (as StndHt-adjusted lung volumes are known to differ significantly: Chinese > Malays > Indians). We recruited 1250 consecutive outpatients aged 20-90 years. Prediction equations of StndHt (with AS, SitHt, weight, age as predictors) for each subgroup of race and sex were formulated with multiple linear regressions. Equations with both AS and SitHt as predictors had the best goodness of fit (SEE = 2.37-2.85 cm, adjusted R2 = 0.67-0.87), as compared to equations with either AS (SEE = 3.00-3.91 cm, adjusted R2 = 0.58-0.80) or SitHt alone (SEE = 3.48-4.00 cm, adjusted R2 = 0.45-0.76). GLM general factorial analyses found that age- and weight-adjusted SitHt-to-StndHt ratios differed significantly among Chinese (0.539), Malays (0.529) and Indians (0.518). This paralleled the ethnic differences in lung volumes. The equations with both AS and SitHt as predictors provide the most accurate estimate of StndHt. Ethnic differences in upper body segment length may explain in part the lung volume differences.

We describe the distribution of body weight, height and body mass index (BMI) by age, sex and ethnicity in Malaysian adults. A national sample of 28,737 individuals aged 20 or older had usable data. They were selected by stratified 2-stage cluster sampling. Percentile tables and curves by age, sex and ethnicity are presented. The body weight and BMI distributions were right skewed, while that of height was symmetrical. BMI distribution showed the expected increase with age, while that of height decrease with age. Differences in BMI between the 2 sexes and among the 4 ethnic groups were observed. Indian had the highest BMI, followed by Malay, Chinese and other indigenous ethnic group.

A cross-sectional study of the nutritional status of schoolchildren aged 7-10 years from the Kuala Betis Resettlement Scheme in Gua Musang, Kelantan was done. A total of 291 schoolchildren were examined but only 183 (62.9%) fecal samples were returned for geo-helminth infection analysis. The prevalence of stunting was 40.4% and underweight was 28.4%. A total of 127 schoolchildren (69.4%) were positive for at least one of the 3 geo-helminth infections. The most common geo-helminth was Ascaris lumbricoides (62.8%), followed by Trichuris trichiura (38.9%), and hookworm infection was relatively low (12.6%). All the anthropometric indices measured were lower in the geo-helminth infected children compared to the uninfected childen, except for the weight-for-height z-score. However the differences were insignificant Geo-helminth infections may not be a significant factor in malnutrition of these schoolchildren. However, with the availability of safe, efficacious and cheap broad spectrum anthelmintics, regular mass treatment should be given in selected areas where the prevalence of geo-helminth infections is still high, so that these schoolchildren will be able to achieve their growth potential during their school years.

This study was conducted to examine how subjects modulate their food intake and energy balance when they migrate from a low energy density food intake pattern to one of high energy density. It was hypothesised that an increase in the energy density of food consumed would result in increased body weight of the migrating subjects unless food intake and energy balance could be modulated. Food selection, food intake, basal metabolic rate (BMR) and anthropometric measurements were made on 53 female and 56 male newly arrived overseas students. All subjects were from Malaysia, but the data was collected at Oxford Brookes University where the subjects were studying. Food intake using 3-day food diaries and food frequency questionnaires (FFQs). BMR and anthropometric measurements including body weight were measured on arrival in the UK and after 3 and 6 months' stay. Student's t-tests and analysis of variance (ANOVA) were used to compare the data. A significant difference (P < 0.05) was found between the energy density of the foods consumed in Malaysia and after 3 and 6 months in the UK. There was also a significant decrease (P < 0.05) in protein consumed. However, there were no differences in total energy intake. From results of the FFQs, differences were found in food selection due mainly to the lack of availability of certain foods in UK supermarkets. No significant differences were found in the BMR and anthropometric measurements made at the start of the study and later assessments. It appears that Malaysian students are able to remain in energy balance and are weight stable at least during the first 6 months of residence in the UK, despite the wider choice of energy dense food available. This suggests that at least in the short term, subjects are able to modulate their food intake in response to changes in the energy densities and free choice of food.

A cohort of one hundred 8-9 year old school children in Northeastern Peninsular Malaysia underwent stool examination, weight and height measurements. Seventy-three children were infected with Ascaris lumbricoides and/or Trichuris trichiura. All infected children were treated with albendazole at baseline, 6 months and 9 months. Measurements were repeated on all but 2 children at 1 year. Repeat stool examination (n = 94) at 1 year revealed a marked reduction in the level of Ascaris infection and a modest reduction in Trichuris infection. There was no difference in net growth between treated children and uninfected controls. Post-hoc analysis by gender however revealed that infected girls (n = 33) experienced significantly higher increments in weight, height and weight for age. Furthermore, children found to be infected at baseline level but worm free at follow-up, were observed to have experienced greater increments in height and height for age. The evidence suggests that periodic antihelminthic treatment may have a positive effect on the growth of subsets of pre-adolescent children but it is emphasised that further work is required to validate these findings.

To evaluate the anthropometric measurements and dietary intake of the free-living elderly in a Chinese community.. A survey was carried out on 48 male and female subjects aged 60 to 96 years using anthropometric, dietary intake and questionnaire techniques.. The study indicated female subjects to have more health problems, like pain at the joints (33%), hypertension (17%) and diabetes (27%) as compared to the male subjects. Dietary intake analysis showed the Chinese male subjects to have a higher energy intake (1,623 kcal) compared to the females (1,197 kcal) even though they did not fulfill the recommended dietary intake. The intake for energy, fats and carbohydrates, was found to be significantly different (p < 0.05) between both sexes. Anthropometric measurements indicated male elderly subjects to be significantly heavier (p < 0.05, 55.4 kg) and taller (161.8 cm) than female elderly subjects (49.5 kg; 146.2 cm respectively). About half of the elderly were normal in their BMI (male 55.6%; female 50%) and only 6.6% of the female subjects were obese. More male subjects were found to be underweight (33%) compared to female subjects (17%). Waist hip ratio was 0.92 for male and 0.87 for female.. Our study showed that female elderly subjects had more health problems compared to male elderly subjects. On the whole, the elderly did not fulfill the recommended amount for energy intake while the percentage for carbohydrates, fats and protein from the total calorie intake were not in accordance with the healthy diet guidelines. Anthropometrically, male subjects were heavier and taller than female subjects. Looking at body mass index, most of the male elderly subjects were in the normal to underweight range. With these results, more research is warranted to give a clearer picture of the Chinese elderly in the country.

Stool examination, height and weight measurements were undertaken on 249 early primary school children at two schools in North-eastern Peninsular Malaysia. Helminth infected children were treated and follow-up anthropometric measurements and stool examination undertaken on all (n = 100) children at one of the schools 16 months later; to observe the relationship between acquisition of infection and growth. Baseline Ascaris prevalence rates at the two schools were 16.0% (23/144) and 47.6% (50/105) respectively whilst Trichuris rates were 33.3% (48/144) and 52.4% (55/105). Hookworm infection was uncommon. There was no difference in weight or height for age between infected and uninfected children at any time. Acquisition of worm infection over the initial 16 month follow-up period was not associated with significant decreases in growth rates. However the small subsets of children with heavy Ascaris infection were consistently lighter and shorter at all evaluation times. They also gained significantly less weight and tended to have reduced linear growth rates between measurements. Further interventional studies are required to determine if this association is one of cause and effect or largely incidental.

The expression and synthesis of IGF-I and IGFBP-3 have been shown to be regulated by hormones and nutrition. We study the effects of malnutrition and iodine deficiency on these growth factors and the height attainment of a group of children.. We measured serum IGF-I and IGFBP-3 levels in a group of Malaysian aborigine children from three jungle settlements; Sinderut and Pos Lanai are known for iodine deficiency and endemic goitre, and Gombak is an iodine replete area with better socioeconomic status.. A total of 246 children were studied, 188 in the age group 4-10 years and 88 in the age group 11-15 years.. All children were assessed anthropometrically and height standard deviation score (SDS) were calculated using the CDC Anthropometric Software package. Malnutrition was confirmed clinically and according to the WHO definition of malnutrition. IGF-I and IGFBP-3 were determined by radioimmunoassay, and T4 and TSH by immunoradiometric assay.. Based on the height SDS, Sinderut and Pos Lanai children were significantly more malnourished and stunted than the Gombak children P = 0.0001). T4 levels were significantly lower (P = 0.0001) amongst the 4-10-years old Sinderut (81 +/- 2 nmol/l) than in Pos Lanai (101 +/- 3 nmol/l) or Gombak (123 +/- 3 nmol/l) children. Similar findings were also seen in the older children; mean T4 levels of those from Sinderut and Pos Lanai (83 +/- 3 and 88 +/- 4 nmol/l respectively), were low (P = 0.0001) compared to Gombak (118 +/- 3 nmol/l). Conversely, TSH levels in both age groups of Sinderut children were significantly elevated (P = 0.0001) (3.5 +/- 0.2 and 3.9 +/- 0.3 mU/l respectively) compared to age-matched groups from Pos Lanal (2.1 +/- 0.1 and 2.2 +/- 0.2 mU/l respectively) and Gombak (1.5 +/- 0.1 and 1.5 +/- 0.2 mU/l respectively). IGF-I and IGFBP-3 correlated significantly with the height SDS of the children, In both the 4-10 (r = 0.400, P = 0.0001 and r = 0.365, P = 0.0001 respectively) and 11-15 years age groups (r = 0.324, P = 0.002 and r = 0.533, P = 0.0001 respectively). Correlation between IGFBP-3 and T4 levels was more significant in the younger children (r = 0.412, P = 0.0001). Association between IGF-I and T4 levels was significant only in the 4-10 years age group (r = 0.237, P = 0.001).. Varying duration and degree of exposure to malnutrition and iodine deficiency resulted in different mean levels of T4, TSH, IGF-I and IGFBP-3 in the three areas. The strong positive associations between IGF-I and IGFBP-3 levels and height SDS suggest that these biochemical measurements are indeed useful indicators of growth and nutritional status in children. The significant correlations between T4 and IGFBP-3 and IGF-1 suggests the importance of thyroid hormones in regulating the synthesis of these growth factors. The age-related increase of these growth factors even amongst malnourished, iodine deficient children implies that age-matched reference ranges are essential for proper evaluation of laboratory results.

To identify the maternal risk factors associated with low birth weight in Malaysia, the records of the 2613 infants delivered at North Okkalapa General Hospital from January to September 1990 were reviewed. The incidence of low birth weight during the 9-month study period was 21.1%; 18.1% of these cases were attributable to intrauterine growth retardation and 3% were associated with preterm births. Univariate analysis identified the following risk factors as significant: age under 20 years (.001), parity 1 (.001), maternal height of 145 cm or under (.01), maternal cigarette smoking (.01), maternal education of 8 years or less (.001), parity 5 or above (.05), and maternal age of 35 years and above (.05). A last birth interval of 1 year or less and more than 3 years was associated with an odds ratio exceeding 1, but the correlation with low birth weight was not significant. These risk factors should be used to design maternal health programs aimed at reducing the incidence of low birth weight.

This study was done to determine the anthropometric measurement patterns of Malay children from wealthy families in Malaysia and to make a comparison with NCHS reference population. A population of 900 children aged between 3-12 years old from Taman Tun Dr Ismail, Kuala Lumpur (TDI), were examined but only 871 of them were eligible for the study. Weight, height, mid-arm circumference and skin fold thickness were measured. The increment pattern of anthropometric measurements of TDI children was quite similar to NCHS except for having a lower median weight for age and height for age. There was prepubescent increase in skin folds thickness in both sexes, followed by a midpubescent decrease and a late pubescent increase. The study indicated that Malay children from a wealthy background have growth rates comparable to children in the West, hence NCHS percentile charts are suitable as a reference for comparing the nutritional status of Malay children in Malaysia.

We conducted a study to measure the peak expiratory flow rate (PEFR), forced vital capacity (FVC) and forced expiratory volume in 1 second (FEV1) in a group of normal Malay primary school children aged 7 to 12 years. PEFR was measured in 920 children (482 boys and 438 girls) while FVC and FEV1 were measured in 292 of them (168 boys and 124 girls). In agreement with previous studies, we found that PEFR was correlated with age and height of the subjects but FVC and FEV1 were correlated with height only. Prediction equations for all 3 lung function indices for Malay boys and girls were formulated. In comparison with the lung function values from Western and Chinese subjects, the lung function values in our subjects are lower.

Spirometry was performed on 1,999 subjects (1,385 males and 614 females) ranging in age from 13 to 69 years and comprising of all the main races in Malaysia. They were divided into 6 age groups. Mean forced vital capacity (FVC) in the males and females was 3.49 +/- 0.02 L and 2.51 +/- 0.02 L respectively. Both FVC and FEV1 correlated negatively with age. Regression analysis on data between the ages of 20 to 69 years revealed an age-related decline in FVC of about 30 ml per year of life in the males and 22 ml per year in the females. Multiple stepwise regression of the data for the prediction of an individual's FVC above the age of 20 years gave an equation for the males: FVC = 0.0407 (height)-0.0296 (age)-2.343 L and for the females: FVC = 0.031 (height)-0.022 (age)-1.64 L. Predicted FVC values derived from equations based on other populations were considerably higher than the observed mean in this study, re-emphasizing the need to be cautious when applying formulae derived from one population to another. Grossly erroneous conclusions may be reached unless predicted equations for lung-function tests for a given population group are derived from studies based upon the same population group.

Prediction equations for peak expiratory flow rate (PEFR) of Malay, Chinese and Indian children were obtained by analysing 1020 PEFR recordings of children free of respiratory symptoms and illnesses. Boys had significantly higher PEFR than girls. For both sexes the highest levels of PEFR were observed in Malays and the lowest in Indians. The differences between Malay and Chinese boys were not statistically significant but the levels of PEFR for Malay and Chinese boys were significantly higher than those for Indian boys. In girls the differences among the ethnic groups were not statistically significant. Although ethnic differences were observed in boys these differences might not be clinically important. A common prediction equation for each sex should be both practical and accurate. When compared with predicted levels for white American and Australian children the predicted levels of PEFR of Malaysian children were found to be lower; these differences could be clinically important and the use of standards for Western children when assessing Malaysian children might not be appropriate.

The nutritional status of 641 children between the ages of 0 to 4 years old, from 835 households in 41 randomly selected rural villages with water supply in Sarawak were determined. Based on Waterlow's classification and the National Center for Health Statistics (NCHS) standards, 61% of the children were stunted and 44.1% were wasted. Based on Gomez's classification and the NCHS standards 81.9% of the children were malnourished. There was no sex difference in nutritional status. The percentage of malnourished children increased continuously with age while the percentage of children who were wasted increased from 6 to 36 months and then it leveled off. The percentage of stunted children also increased with age but the increase was sharpest in children who were 12 to 23 months old. It is noted that the Gomez classification overestimates the prevalence of undernutrition.

We reviewed our data from 122 records of patients taking phenytoin for the treatment of various types of epilepsy and selected 15 (age range 10-43 years old) who were on phenytoin alone to calculate Michaelis-Menten pharmacokinetic parameters. The average Vm and Km for this age group was found to be 8.45 mg/kg/day and 6.72 mg/litre, respectively. Km was independent of age and weight. Vm correlated well with weight but there was no relationship with age.

Over the past hundred years in industrialised countries and recently in some developing countries, children have been getting larger and growing to maturity more rapidly. This paper compares the growth of Malaysian children with similar socioeconomic backgrounds but born about twelve years apart. Data were obtained from records of 227 children born between 1968 and 1973 and 238 children born between 1980 and 1985. The children were followed-up regularly at the University Hospital Child Health Clinic in Kuala Lumpur for a variable period from birth to five years of age. Measurements for their weight, length and head circumference were taken at each visit. There is a directional indication that boys and girls of the 1980-1985 cohort are taller, heavier and have bigger head circumferences from birth to five years of age and the difference widens as the child grows older. This study clearly shows that a positive secular trend has taken place in the last decade, reflecting an improvement of living conditions with time. The factors involved in the positive secular trend are manifold and the most important is probably nutrition.

126 Malaysian children, 65 boys and 61 girls from higher income families were followed-up regularly from birth to six years of age in the University Hospital, Kuala Lumpur. Their physical growth, development, dietary and illness patterns were measured at each visit. The study confirms the observations of previous studies that boys are, on the average, heavier and taller than girls and that Asians are smaller in size with relatively shorter legs compared with children of European ancestry. These racial differences are due to a combination of genetic and environmental differences. Since there are genetic differences in the size and shape of children, standards applicable to the specific population should be used to obtain the best results when assessing the health of an individual child. The growth charts presented in this paper can be used as standards to monitor the growth of Asian infants and pre-school children.

A mixed cohort (retrospective and prospective) study was conducted on Malay pregnant women attending a rural health center in Muar district of Malaysia in 1985. Among the 605 women who were eligible for the study, 477 were exposed to Ramadan fasting. The remainder comprised of nonexposed or "o" day faster group. Controlling for the confounders, the study showed that weight gain during pregnancy and infant birth weight, among the varying exposed and nonexposed to Ramadan fasting groups, were not statistically different. The gestational age of the infant vary among the exposed groups and the unexposed by 4-7 days and this is significant statistically (p=0.001).

In Malaysia, an aqueous extract of Tinospora crispa stems is taken orally to treat diabetes mellitus. In the present study, normal and alloxan-diabetic rats were used to evaluate the hypoglycaemic properties of the extract. A hypoglycaemic effect was observed in moderately diabetic rats with concomitant improvement in insulinaemia. After a 2-week treatment with the extract (4 g/l in the drinking water), these rats also showed improvement in glucose tolerance. Moreover, acute intravenous treatment with the extract (50 mg/kg) caused an increase in plasma insulin levels. The data support the traditional belief that T. crispa extract could improve diabetic conditions by virtue of its action on the endocrine pancreas.

In experiments conducted over a four-year period the effect of pasture type (Setaria sphacelata and a Brachiaria decumbens/Leucaena leucocephala mixture), management system (rotational grazing and cut and carry) and level of concentrate supplement (0, 4 and 6 kg fresh weight/cow per day) on milk production in smallholder dairy units was examined. All units were 1 ha in size and stocked with five Sahiwal X Friesian cows. Milk yields/ha were higher from rotational grazing and the brachiaria/leucaena pasture when compared with the cut and carry system and the setaria pasture respectively. In subsequent experiments smallholder units were based on brachiaria/leucaena and rotational grazing. A supplement of 4 kg fresh weight of concentrate (11 MJ/kg DM and 150 g/kg DM CP) increased milk yield/ha from 7,760 to 13,045 kg while in a third trial milk yield/ha was further increased from 14,148 to 16,760 kg when concentrate level was raised from 4 to 6 kg fresh weight/day. The results indicate that smallholder dairy units in Malaysia could be economically viable and competitive with other agricultural enterprises such as rubber and oil palm.

Subcutaneous body fat and Quetelet's Indices (QI) of 52, 18-29 year old normal female volunteers were determined. These body mass indices were then grouped according to the phase of each subject's menstrual cycle, early or late follicular and early or late luteal phase. The subcutaneous body fat is 27.07 +or- 1.0% in the early follicular but drops to 24.68 +or- 1.84% in the late follicular phase. The value then rises significantly higher than that in the late follicular phase to 30.14 +or- 1.15% (P0.02) in the early luteal drops to 27.17 +or- 0.55% towards the level of the early follicular phase (P0.05). Variations in the values of QI during each menstrual cycle exactly mirror those for subcutaneous body fat. The fall in the 2 body mass indices during the late follicular phase coincides somewhat with the established preovulatory LH and FSH surges as well as the high levels of estrogen of this period. On the other hand the significant rise in the 2 parameters during the early luteal phase coincides with the marked rise in the ratio of progesterone to estrogen. Clearly, increased levels of progesterone relative to estrogen appear to cause an increase in the body fat during each menstrual cycle. The implication of this finding for women on contraceptive pills which are predominantly progesterone and those whose normal menstrual cycle is "interrupted" at the early luteal phase by a successful fertilization raises very interesting questions with regards to prediction of ovulation.

Young sedentary adult males of Malay, Indian, and Chinese origin who had established continuous residence in tropical Malaysia and presumed to be naturally acclimatized to heat, were studied to evaluate their physiological responses to a standard heat stress test. The Malay and Indian races have evolved in hot and humid geographical zones, whereas the Chinese originated from a temperate area. Subjects exercised at 50% VO2max alternating 18 minutes walking and 2 min rest during a 2-h exposure to an ambient of 34.9 degrees C dry bulb and 32.1 degrees C wet bulb. Heart rates, core and skin temperatures, sweat rates, and oxygen uptakes were measured during the heat exposure. The subjects of Malay origin exhibited the least circulatory stress of the three ethnic groups. The data obtained on these long-term residents of a hot-wet climate and who were considered acclimatized to this environment were compared to experimental data obtained by other investigators and other ethnic groups.

Morality in Peninsular Malaysia has reached a level that is quite similar to that prevailing in the low mortality countries. This article systematically documents changes in mortality levels and differentials in Malaysia over time and relates these to changes in development indicators and health-related policies. Remedial measures undertaken by the authorities including the expansion of hospital and health services into the estates, together with a comprehensive malaria-eradication program, improvements in sanitation laws, and increased provision of public utilities and education, resulted in beriberi being eliminated and the incidence of malaria, typhus, and smallpox being greatly reduced by the time of World War II. The gain in life expectancy over the period of 1957-1979 was greatest for the Malay, the most significant period being 1957-1967, which saw the introduction of rural health programs. The infant mortality rate and the neonatal and post-neonatal rates declined substantially for all ethnic groups in Peninsular Malaysia for the same time period. Although the lower infant mortality of the Chinese can be explained by their advantageous socioeconomic position the same reason cannot explain the lower decline in infant mortality levels of the Indians. Much still needs to be done to narrow, if not to eliminate, the existing mortality differentials of different groups in the country. Overall, the quality of life of the general population can be further enhanced by reducing the high mortality level of disadvantaged groups.

1. Anthropometric variables, resting heart rate and respiratory gas exchange were measured in twelve male and nine female Asiatic adult Moslems during the month of Ramadan, the week before and the month after Ramadan. 2. Energy intakes were estimated from dietary recall during fasting and non-fasting conditions. 3. Both male and female subjects experienced a decrease in body mass with the reduction in energy intake during fasting. Males experienced a greater reduction than females in resting heart rate; females lost more body-weight and subcutaneous fat than males. 4. Urine output and fluid intake were measured in twelve male subjects for 1 d during each week of fasting and 1 d during the pre-fasting control period. Among the subjects examined, the Ramadan regimen did not result in changes in the pattern of fluid exchange.

This study examines the possibility that estimation of the effect of breast-feeding on infant survival is affected by selection bias, in that children who are healthier at birth may be more likely to be breast-fed. Data are from the 1976 Malaysian Family Life Survey. "Ordinary logit models for breast-feeding and survival are estimated, and the results suggest that selection is indeed present. For example, children of higher birth weight appear to be more likely to be breast-fed and likely to survive. In addition, weight at birth and the duration of breast-feeding appear to be linked." Using birth weight as an indicator for the child's health, the authors conclude that "the direct influence of breast-feeding on survival remains of overwhelming importance even after corrections for selection bias are made."

Singapore is a tropical island city-state with a population of 2.4178 million consisting of Chinese (76.7%), Malays (14.7%), Indians (6.4%) and other races (2.2%). A diabetic survey of the adult population, aged 15 years and above, carried out in 1975, shows that the prevalence of diabetes is 1.99%; it is higher in males (2.36%) than in females (1.64%). It occurs mainly in the age group 40 years and above (5.08%) and is uncommon in the age group 15-39 years (0.40%). In males, the highest prevalence of diabetes (7.0%) is in the age group 45-49 years while in females the highest prevalence (7.2%) is in the age group 55-59 years. 43.3% of the diabetics are of normal weight while 44.3% are overweight and 12.4% are underweight. 59.6% of the diabetics are newly diagnosed while 40.4% are known diabetics; 64.3% of the newly diagnosed diabetics have no symptoms. The prevalence of diabetes among the Indians (6.07%) is significantly higher than that in Malays (2.43%) and Chinese (1.55%). Indian diabetics have a slightly higher positive family history of diabetes (12.7%) than Malays (10.9%) and Chinese (6.5%). Obesity is commoner in Malay diabetics (64.7%) than in Chinese (41.6%) and Indians (35.7%). The possible factors leading to the significantly higher prevalence of diabetes among the Indians compared to the other ethnic groups in Singapore are discussed. It is suggested that the Indian gene is susceptible to diabetes (diabetic genotype) and increased food consumption, altered lifestyle and greater obesity leads to the expression of diabetes.(ABSTRACT TRUNCATED AT 250 WORDS)

Estimated prevalence of diabetes mellitus in Malaysia was about 2%. Diabetes was most common in Indians especially males and least common in Chinese. There was a slight male preponderance seen in Malays and Indians. Positive family history was obtained in 14% of cases most commonly in Malays, almost 1/3 of whom had more than one family member with diabetes. Familial association was uncommon in Chinese. Over 50% of patients were overweight. Obesity was noted in nearly 70% of female Malays and Indians while the majority of Chinese were not overweight. More than 80% of patients were non insulin requiring. Youth onset diabetes was considered rare; those 10 years and below were estimated to be only 0.4% and below 20 years of age between 2%-4% of the diabetic population. Females were twice as common than males in this type of diabetes and familial association was greater. Malnutrition-related diabetes and pancreatic calcification were not well-documented but youth-onset non insulin requiring diabetics with mild symptoms but strong family history of diabetes were observed. More than half of hospital-based patients had evidence of complications, mainly amongst Malays and Indians. Hypertension was the most frequent associated disease followed by foot ulcers and ischaemic heart disease. Hypertension usually associated with chronic renal failure was most common amongst Malays while gangrenic ulcers and heart diseases were seen mainly in Indians. The major causes of death were chronic renal failure, myocardial infarction, ketoacidosis, stroke and septicaemia related to gangrene.(ABSTRACT TRUNCATED AT 250 WORDS)

A Specialist Clinic was commenced in August 1983, from the Medical School at Universiti Sains Malaysia, Penang, Malaysia to assess: 1) the present control and 2) the incidence of complications in a diabetic population already receiving primary health care at Penang General Hospital. The ethnic groups among the diabetics were Chinese (39%), Malays (26%) and Indian (35%). There was a greater percentage of Indians than would be expected from the ethnic distribution of the population of Penang. The results of the first 100 (43 males and 57 females) non-insulin dependent diabetic patients are reviewed. The mean age was 54 years, 41% had relatives with diabetes, and all were taking oral agents. The diet comprehension and compliance were poor. 65% of the group, 54% of males and 75% of females were obese. The mean blood glucose was 11 m.mols/l (fasting) and 12.8 m.mols/1 (2 hours post prandial). The complications seen in the 100 diabetics were: albuminurea 41, skin infection 37, cataracts 35, hypertension 32, peripheral sensory neuropathy 32, retinopathy 22, ischaemic heart disease 19, autonomic neuropathy 10, impaired renal function 4 (urea or creatinine elevated), foot ulcer 2 and gangrene 1. Urinalysis for glucose at the Clinic showed very little correlation with blood glucose at the same time. Nine out of 43 males admitted to impotence on questioning. Comparisons of findings in Penang were made with recent studies in Singapore and Hong Kong.

The study presents recent data on the prevalence and pattern of nutritional anemia in the Maternity Hospital, Kuala Lumpur. A total of 309 pregnant women in their 3rd trimester, of Malay, Chinese and Indian origin from the lower socio-economic strata were randomly selected for the study. Hematological indices (including Hb, PCV, MCHC, and TRBC), serum iron, transferrin saturation and ferritin, serum folate as well as protein and albumin were determined. Based on Hb and PCV values, 30-40% of the women could be considered anemic; approximately 50% of them presented with unsatisfactory serum iron, transferrin saturation and ferritin values; 60.9% had low serum folate levels; and about 30% may be considered to be of poor protein nutriture. Anemia in the study population was seen to be related mostly to iron and to a lesser extent, folate deficiency. Hematological, iron, folate and protein status was observed to be the poorest amongst the Indian women, better in the Malay group and generally the best amongst the Chinese women. Birth records of 169 of these women revealed that all of them had live births. Nearly all the infants were delivered by normal vaginal delivery (NVD). The mean gestational age was 38.6 weeks. One of the infants had a birth weight of 2.0 kg; incidence of low birth weight, 2.5 kg, was 8.3%. Although there was a trend of deteriorating hematological, iron and protein status of women from the 0, 1-3 and 4 parity groups, these differences were not statistically significant.

The aim of this investigation is to study the effect of family planning on declining maternal and infant mortality rates in Malaysia since the National Family Planning Program began operation in May, 1967. Data were derived from the registration of vital events and reports from the Malaysian Family Life Survey conducted in 1978, and demonstrate declines in maternal and infant mortality rates. Although this is a result of a combination of factors (e.g., socioeconomic development, high quality health and medical services) the contribution of family planning is significant. Between 1957 and 1980 the maternal mortality rate declined by 80%. High risk births declined from 10.2% to 8.2% for mothers under age 20, and from 15% to 13.7% for mothers over age 35 during the 1967-1977 decade. From 1955 - 1980 the infant mortality rate declined by 68.2% to a level of 24.9/1000 live births; this may be partly due to the shift to lower order births (and therefore low risk) as a result of better family planning. Perinatal mortality declined 6.7% in the pre-implementation years (1957 - 1967) and 19.8% in the post-implementation years (1967 - 1977). Low birthweight is a significant correlate of infant survival, and data from this study indicate that birthweights increase with maternal age up to 30-34 years, then begin to decrease. Birthweights are also lower (and infant mortality higher) for babies born at birth intervals of less than 15 months. Therefore, concerted efforts in family planning education need to be directed to vulnerable groups such as young mothers (under 19) and older mothers (over 40).

Serum samples were obtained within 3 days of capture from 106 cynomolgus monkeys (Macaca fascicularis) in peninsular Malaysia. Fifty-two monkeys were trapped on the fringes of palm oil estates and 54 in dense primary jungle. Sera were tested for antibodies to hepatitis A virus (HAV) with a commercial radioimmunoassay. Twenty-four animals had detectable serum anti-HAV activity (6 of 52 from palm oil estate sites and 18 of 54 from primary jungle sites). Among monkeys at both sites, antibody prevalence was strongly correlated with animal weight: overall only four of 69 monkeys (6%) weighing less than 2.0 kg had serum anti-HAV antibodies, while 14 of 29 (48%) weighing 2.0 to 3.9 kg, and 6 of 8 (75%) weighing 4.0 kg or more, had serum anti-HAV antibodies. These data suggest that wild cynomolgus monkeys in Malaysian jungles become infected with HAV or an HAV-like virus at a rate comparable to that of humans in the same region, and raise the possibility of a sylvatic cycle for HAV.

Neonatal morbidity and mortality in Peninsular Malaysia are still major heath problems. Although there has been steady decline in neonatal mortality over the years since 1955, the rate of decline has been encouragingly more rapid over the most recent period studies, e.g. 1975-1980. As a component of infant deaths, the proportion of early neonatal deaths has increased from 20.7% in 1955 to 50.6% in 1980. The incidence of low birth weight is about 10.5 to 11%, although this too shows signs of gradually decreasing. More than 1/3 of the babies born did not have their birth weights recorded. Those not recorded are assumed to be those babies delivered at home by traditional birth attendants. Mortality rates decreased with increasing birth weights. Low birth weights are high among Indian and Malay communities in Ma.laysia and these groups also have higher neonatal mortality rates compared to the Chinese for the same time period. Low birth weight babies are born more frequently to mothers 15-24 years of age independent of ethnic background. First borns tend to be more frequently of low birth weight among all 3 ethnic groups. Principal causes of death are difficult to assess because of the scarcity of a standardized classification of these deaths; consented autopsies are difficult to obtain and the services of perinatal pathologists are not available. In addition, approximately 45% of the deaths are non-medically inspected or certified. The clinical classification of neonatal deaths used at the Maternity Hospital, Kuala Lumpur, indicate that asphyxia, surfactant deficiency disease (respiratory distress syndrome) and bacterial sepsis are responsible for about 70% of the total neonatal deaths; meconium aspiration syndrome accounted for another 8-9%. Although data relating to neonatal mortality is not optimal in Malaysia, there is enough to suggest that new strategies are needed to improve maternity and newborn care.

Basal and pentagastrin stimulated acid output was measured in 80 normal and 179 duodenal ulcer subjects of Chinese, Indian and Malay origin. Basal and maximally stimulated acid output was significantly higher in duodenal ulcer patients compared with normal subjects. There was however considerable overlap and less than one in four duodenal ulcer patients were hypersecretors. The acid output (and hence the parietal cell mass) was lower than in Caucasian subjects and this was possibly related to weight differences. The acid output did not differ significantly in the Chinese, Indian and Malay subjects, suggesting that parietal cell mass in the three racial groups is closely similar. The difference in frequency of duodenal ulcer disease in the three racial groups is thus not related to gastric secretory capacity.

Paired augmented histamine tests using 40 microgram 60 microgram histamine acid phosphate (HAP) per kg body weight were conducted on each of 57 Asian subjects. The mean peak acid output (PAO) for the total series to the two different doses of HAP was 22.3 mEq/hr and 23.3 mEq/hr respectively and the difference was not statistically significant according to the paired t test. There were similarly no significant difference in PAO to the two doses of HAP in the following groups of subjects: 26 Chinese, 17 Indians, 14 Malays; 24 subjects with duodenal ulcer, 16 controls; 28 subjects with body weight below 50 kg, 19 between 50-60 kg and 10 exceeding 60 kg. These findings differ from earlier reports that for maximal gastric secretion Asians required a higher dosage of histamine compared with Caucasian subjects.

A breeding colony utilizing a harem mating system was established to study the feasibility of breeding cynomoglus monkeys, Macaca fascicularis, in Malaysia. Two groups consisting of 10 females and one male each were evaluated over a 3 period. Forty births were recorded; one was stillborn, 11 died while nursing, and 28 were weaned. The average time to wean offspring was 230 days with an average weight at weaning of 0.858 kg. The average time for conception to take place after weaning was 50 days. Of the 20 breeder females, six produced three offspring each, nine produced two offspring each, four produced one offspring each and one remained barren throughout the project. Three different weaning systems were evaluated. The best method was caging the mother-infant pair within or adjacent to the breeding room followed by a two-part cage system which allowed the infant to continue nursing and also obtain solid food inaccessible to the mother.

Body weight and nine body measurements were recorded on 79 mature Kedah-Kelantan cows at two locations. The Kedah-Kelantan is an indigenous cattle of Malaysia. A principal component analysis was used to study size and shape as indicated by the dependence structure among measurements. The total variation among measurements associated with the first principal component which was interpreted as a measure of general size was 40.8%. The second principal component contrasted cows tall at the withers, and deep at the chest with top line sloping downward and under line sloping upward from front to rear with those having less wither height and chest depth and straighter lines. This contrast accounted for 14.3% of the variation in body dimensions. The third principal component contrasted long, narrow, and deeper cows with a more compact type. This contrast accounted for 10.7% of the variation in body dimensions.

The weights and heights of 3,312 Malaysian primary school boys and girls, aged 6 to 11 years, belonging to various ethnic groups in Malaysia were measured. On the whole, the Chinese children were taller and heavier than the Malay and the Indian children who were the least heavy among the three ethnic groups. Economically the Indians were the poorest among the three ethnic groups and they also had the largest family size. When the household incomes were taken into consideration it was found that the growth achievement of the higher income children was better than that of the poorer children, irrespective of their ethnic groups. It is interesting to note that, although the Indian children as a whole, were the least heavy of the three ethnic groups, yet the growth achievement of the higher income Indian children was similar to that of the higher income Chinese children. The differences in growth achievement of the various ethnic groups are probably due to environmental differences, rather than genetic differences. It seems likely that Malaysian children of different ethnic groups (Malay, Chinese and Indian) can attain similar statures if environmental conditions are similar.

Pneumonia and diarrhoeas are an important cause of toddler mortality and morbidity in developing countries. Of the 147 children admitted to the University Hospital at Kuala Lumpur in 1971 for pneumonia and diarrhoeas 50 (34%) were found to be suffering from protein-calorie malnutrition of varying degrees of severity. The malnourished children tended to come from poorer homes, and to have a larger number of siblings born in rapid succession when compared with normal weight children. Anemia was more common among the malnourished children. The interaction of infection and malnutrition and the social implications of these diseases are important. It is vital that hospitals in developing countries promote health in addition to their traditional curative role.

During a routine medical examination of 5280 government employees (2736 males, 2544 females; age range 17 to 66 years; 3386 Chinese, 1252 Malays, 508 Indians and 134 other ethnic groups) diabetes was found in 31 (0.59%). The prevalence was higher in males (0.95%) than in females (0.20%). The highest prevalence was in the age-group 50 to 59 years (5.4%); at ages 30 to 66 years, the overall prevalence was 2.18%. The prevalence of diabetes is higher in Indians (2.76%) than in Chinese (0.30%) and Malays (0.48%); the difference is statistically significant, as it also is in the age-group 30 to 66 years (Indians 6.36%, Malays 1.39%, Chinese 0.9%). Of the 31 cases, only four were previously known and only nine were overwieght. The possible reasons for the higher prevalence of diabetes in Indians are discussed.
