Impact of beta-carotene supplementation through red palm.
A 10-month long feeding trial was conducted to assess the impact of beta-carotene supplementation through red palm oil (RPO) with the focus on vitamin A status, morbidity status and acceptability of an RPO-incorporated noon-meal as a dietary supplement among two cohorts of 409 (experimental) and 346 (control) preschool children in two southern districts of rural Tamil Nadu, selected by stratified random sampling. Information was gathered on ocular symptoms of vitamin A deficiency and anthropometry, and blood samples were drawn at baseline and final rounds for estimation of serum beta-carotene, retinol and tocopherol. Data about Socioeconomic Status (SES) were collected once during the study period, while information on attendance, consumption and morbidity was recorded by preschool teachers. The results showed the following. 1. Significant improvement in the vitamin A status of children in terms of disappearance of Bitot's spots (50.0 per cent) in the experimental group vs. 28.0 per cent in the control group. 2. After feeding of RPO, incidence rate of new Bitot's spots cases was low at 2.13 in the experimental children vs. 4.78 in control children. 3. Marked improvement in the serum beta-carotene levels after 10 months of feeding. 4. RPO is acceptable to children as an edible grade oil as there is no perceptible difference in the consumption pattern between experimental and control children.

Chronic low intakes of vitamin A-rich foods in households with xerophthalmic children: a case-control study in Nepal.
Dietary patterns in 81 rural Nepali households with a 1-6-y-old child with a history of xerophthalmia were compared with dietary patterns of 81 households with an age-matched nonxerophthalmic control subject. Weekly food-frequency questionnaires were collected from case and control "focus" children, a younger sibling (if present), and the household 1-2 y after recruitment and treatment of cases. Control households and children were more likely than case households and children to consume vitamin A-rich foods during the monsoon (July-September) and major rice harvesting (October-December) seasons. Cases were less likely to consume preformed vitamin A-rich foods throughout the year [odds ratio (OR) = 1.2-4.5] with the strongest differences observed from October to December (OR = 2.0-4.2). Dietary risks were generally shared by younger siblings of cases, suggesting that infrequent intake of beta-carotene and preformed vitamin-A rich foods begins early in life and clusters among siblings within households, a pattern that is consistent with their higher risk of xerophthalmia and mortality. In developing countries where vitamin A deficiency is endemic, dietary counseling for children with xerophthalmia should be extended to their younger siblings. Moreover, dietary intake of preformed vitamin A may be as, or more, important as carotenoid-containing food consumption in protecting children and other members of households from vitamin A deficiency.

Xerophthalmia in Ethiopia: a nationwide ophthalmological, biochemical and anthropometric survey.
A total of 6636 children, aged from 6 months to 6 years and selected throughout the country using a multi-staged stratified sample design, were examined for signs of xerophthalmia. The concentrations of retinol and of beta-carotene were measured in 742 children, including those with xerophthalmia and every twentieth of the remaining children. Anthropometric measurements were made on 2909 of the children. Bitot's spots were seen in 1.0% of all children, with a higher prevalence in the pastoral (1.6%) and cropping (1.1%) agro-ecological zones than in the zones characterized by cash crops (0.4%) and 'ensete' (false banana, Ensete ventricosum) (0.0%). One case of corneal xerosis and 2 cases of corneal scar were also seen. Serum retinol levels were in the 'deficient' range (less than 0.35 mumol l-1) in 16% and 'low' (0.35-0.69 mumol l-1) in 44% of children. Serum retinol and clinical signs did not show any correlation with occupation and education of head of household, household size or anthropometric measurements. More stunting than wasting was observed, with peak prevalence of these signs of malnutrition being observed in the second year of life.

Vitamin A activity of buriti (Mauritia vinifera Mart) and its effectiveness in the treatment and prevention of xerophthalmia.
The fruit of buriti, a palm tree that grows wild in some regions of Brazil, contains beta-carotene in its oily fraction in a concentration 10 times higher than that of red-palm oil. The effectiveness of buriti sweet in the treatment and prevention of xerophthalmia was tested in 44 children aged 43-144 mo through daily supplementation with an amount corresponding to 134 micrograms retinol equivalent over 20 d. The results demonstrated that this natural food source of vitamin A can reverse clinical xerophthalmia and restore liver reserves of the vitamin, suggesting its possible utilization in intervention programs to combat vitamin A deficiency in countries where the fruit is available or has the potential for cultivation.
