Menstrual cycle abnormalities and subclinical eating disorders: a preliminary report

Area of Science:

• Reproductive endocrinology
• Psychiatry
• Clinical psychology

Background:

• Menstrual dysfunction is frequently observed in individuals with anorexia nervosa and bulimia nervosa.
• Previous research often confounded menstrual abnormalities with low body weight.
• A complex interplay between eating disorders and menstrual status is suggested by emerging evidence.

Purpose of the Study:

• To investigate the prevalence of menstrual abnormalities in women with subclinical eating pathology.
• To compare menstrual abnormalities in subclinical eating pathology to age-, education-, and weight-matched healthy controls.

Main Methods:

• Two studies were conducted to assess menstrual history.
• Participants included women with subclinical eating pathology and a control group of normal subjects.
• Data were collected on menstrual abnormalities and compared between groups.

Main Results:

• In Study I, 93.4% of subclinical subjects reported menstrual abnormalities versus 11.7% of controls.
• In Study II, 100% of subclinical subjects reported menstrual abnormalities versus 15.0% of controls.
• These findings indicate a high prevalence of menstrual dysfunction in women with subclinical eating pathology.

Conclusions:

• Menstrual dysfunction is common in women with abnormal eating attitudes, independent of significant weight loss or diagnosable eating disorders.
• The study suggests a direct association between disordered eating attitudes and menstrual irregularities.
• Further research is needed to elucidate the specific mechanisms underlying this association.
