Males with eating disorders: challenges for treatment and research

Males represent only 10 percent of eating disorder cases. This gender discrepancy is among the most extreme in psychiatry and medicine. Determining what differences in etiology and mechanism best explain the discrepancy presents an intellectual challenge. Beginning at about the third grade, boys and girls diverge in social development. Boys show significantly less desire to lose weight, express dissatisfaction with the upper rather than the lower body, and use dieting to achieve specific external goals rather than as a cultural norm. Males reach a significantly higher body mass index (BMI) than females do before they beginning dieting. (27.2 versus 24.3, p < .01). While overall treatment principles are similar, males in treatment require attainment of a different hormonal milieu (testosterone), attention to past and future sexual role, amelioration of perception of stigma, and preparation for return to male social roles. Males and females suffer comparable degrees of osteopenia and brain shrinkage during anorexia nervosa. The effectiveness of antidepressants in males with eating disorders (compared with that in females) has not been well studied. Male gender is not an adverse factor in short-term or long-term treatment outcome. Understanding the lower frequency of these illnesses in males may lead to more effective means of protecting girls from eating disorders and from the culturally induced distress about normal body size and shape that burdens adolescent development and adult life.
