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

摘要

Predictors of weight at resumption of menses were studied in 118 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.
