The purpose of this study was to describe a sample of 40 eating disordered adolescent males in order to complete a series of follow-up studies on adolescent females who were seen for evaluation and treatment at Boston Children's Hospital Outpatient Eating Disorders Clinic between 1981 and 1991. The sample was drawn from all males seen at the clinic (between 1981 and 1995) who were eligible for inclusion because of a diagnosis of anorexia nervosa, bulimia nervosa, or eating disorder-not otherwise specified. Data were collected via retrospective chart review and three self-administered quantitative scales. Although the response rate to the mailed follow-up questionnaires was low, comparisons with the three studies on females were consistent with those of other investigations, suggesting that the course and outcome of these illnesses are remarkably similar for males and females. The findings support the idea that clinicians, coaches, peers, and family members should encourage young men to share concerns about body image and weight at an earlier, less severe juncture, with assurance that these issues are common to both sexes.
