Seasonality and the prediction of weight at resumption of menses in anorexia nervosa

Predictors of weight at resumption of menses were studied in H 8 subjects with lifetime anorexia nervosa who recovered their ovarian function without hormonal therapies. About 64% of subjects had menses resumption during spring/summer season. The body mass index (BMI) at resumption of menses was significantly predicted by BMI at amenorrhea, highest lifetime BMI, levels of hostility, and spring/summer season at the time of recovery.
