In this article, the authors hypothesized that low leptin levels are associated with the absence of menstruation. They assessed the predictive value of leptin, body mass index, fat mass and percent body fat for lifetime occurrence of amenorrhea. They then examined serum leptin levels in 43 underweight female students. According to this study, a critical leptin level is needed to maintain menstruation. This research has implications for the evaluation and treatment of many physiological and psychological disorders, especially eating disorders.
