leptin and Premenstrual-Dysphoric-Disorder

In this study, we evaluated the changes in leptin and ghrelin concentrations, eating behavior, depression, and impulsivity and their correlations within the luteal phase among women with premenstrual dysphoric disorder (PMDD).. In 63 women with PMDD and 53 healthy controls, we prospectively evaluated serum levels of leptin and ghrelin, Body Mass Index(BMI), and self-reported sweet cravings, cognitive restraint, uncontrolled eating, emotional eating, depression, and impulsivity during the early luteal (EL) and late luteal (LL) phases.. Compared with the controls, the women with PMDD had higher BMI, higher leptin concentrations in the EL and LL phase, and leptin concentrations increased from the EL to the LL phase. However, there is no significant difference in ghrelin. Women with PMDD increased sweet cravings and uncontrolled eating from EL to LL phase. No significant correlation was observed between the EL-LL changes in leptin or ghrelin concentrations and those in eating behaviors. Both depression and impulsivity correlated with sweet craving and uncontrolled eating. Depression mediated the association between PMDD and uncontrolled eating. The BMI of women with PMDD positively correlated with their EL-LL change in leptin, and LL depression levels and emotional eating.. Young women with PMDD had higher leptin concentrations and BMI in the luteal phase. The LL leptin level was not the primary factor responsible for the increased uncontrolled eating of PMDD. Whether the increased eating and depression in the LL phase contribute to the risk of obesity or hyperleptinemia among women with PMDD need to be evaluated in the future.

A marked increased in food intake in the late-luteal phase is a characteristic symptom of premenstrual dysphoric disorder (PMDD). The aim of the study was to evaluate the leptin level, caloric intake, and eating behaviors of women with PMDD across the menstrual cycle among normal-weight and overweight subjects, respectively.. A total of 62 women with PMDD and 69 controls were recruited following psychiatric interviewing and underwent prospective investigation. The leptin level, caloric intake, and three factors related to eating behavior were assessed in both the late-luteal and follicular phases.. The women with PMDD had greater increases in caloric intake, sweet caloric intake, and uncontrolled eating in the late-luteal phase than the controls. Among the normal-weight women, the leptin level was negatively correlated with caloric intake. The normal-weight women with PMDD had a lower leptin level, a lower leptin/body fat percentage (BFP), a higher caloric intake, and higher uncontrolled eating and emotional eating in the late-luteal phase than the normal-weight controls. Their leptin level was correlated negatively with sweet caloric intake. On the other hand, the overweight women with PMDD had a higher leptin level than the normal-weight women with PMDD and no decline was observed in their leptin level in the late-luteal phase. There were no differences in the leptin level between the overweight women with PMDD and the overweight controls. They also had a higher sweet caloric intake and higher uncontrolled eating and emotional eating than the overweight controls.. A decline in the leptin level is associated with late-luteal overeating among normal-weight women with PMDD. Hyperleptinemia and a high sweet caloric intake of overweight women with PMDD should be monitored and addressed in order to attenuate the risk of leptin resistance. The detailed roles of leptin and other psycho-neuro-endocrinology factors in the mechanism of overeating among women with PMDD should be evaluated in future study.
