Sex-specific issues in eating disorders: a clinical and psychopathological investigation.

OBJECTIVE: To highlight the characteristics of eating disorders (ED) in males, with particular attention to sex-related clinical features and psychiatric co-morbidities.

METHOD: Out of 280 persons, referred to our outpatients ED clinic between January 2011 and June 2014, 267 with complete information were included in this retrospective observational study.

RESULTS: The men/women ratio was one to five (male 16.5% vs female 83.5%) with an increasing proportion of male patients over the years. The most frequent ED in males was binge eating disorder, whereas in females anorexia nervosa and bulimia nervosa prevailed. Excessive exercising and fasting were the most common compensation behaviours in males; while self-induced vomiting and laxative-diuretic abuse were more typical in females. Among women, the most represented psychiatric co-morbidities were mood and somatoform disorders, whereas among men, anxiety and psychosis spectrum disorders were the most frequent ones. Borderline and histrionic personality disorders were prevalent in female ED, while narcissistic and antisocial personality disorders prevailed in males.

DISCUSSION: ED in men is a growing phenomenon. Male ED, compared to female ED, show differences in clinical presentation, symptoms and co-morbidities. Despite the use of clinical and psychometric evaluating tools targeting female patients, sex differences do exist and additional studies are required to investigate male specific issues in ED.
