Abstract

Abstract : Introduction: Amenorrhea is one of the most frequent and serious consequences of Anorexia Nervosa (AN). Resumption of menses (ROM) is considered an important goal and is associated with a better outcome. Objectives: To investigate the role of age, Body Mass Index (BMI), diagnostic subtype (restrictive vs binge-purging), history of childhood abuse, duration of illness, psychopathology and sex hormones on ROM in AN. Methods: 52 patients with AN and amenorrhea were enrolled at the start of treatment. Clinical parameters of interest were collected, and questionnaires were administered for the assessment of general (SCL-90-R) and specific (EDE-Q) psychopathology. Blood samples were taken to assess FSH, LH and estradiol levels. All patients were monitored regularly through psychiatric checkups until ROM, for up to four years. Results: A total of 30 (57.7%) subjects recovered their menstrual cycle in the follow-up period (mean time: 18.7 ± 14.8 months). Recovery was more frequent in the binge-purging subtype than in the restrictive subtype (82.4% vs 48.6%, p=0.019), and was significantly associated with diagnostic crossover (odds ratio=10.0, p=0.032). Multivariate Cox regression showed an increased likelihood of menstrual recovery for binge-purging subtype (p=0.005) and for those reporting a history of childhood abuse (p=0.025). Early ROM was also associated with baseline SCL-90-R scores (p=0.002) and FSH (p=0.011), while a longer duration of illness (p=0.003) and EDE-Q scores (p=0.009) predicted a later recovery. Conclusions: This study highlights the role of duration of illness, childhood abuse history and psychopathological characteristics in subjects with AN at the start of treatment in predicting ROM. Disclosure: No significant relationships.
