Context Eating disorders are severe conditions, but little is known about the prevalence or correlates of these disorders from population-based surveys of adolescents. Objectives To examine the prevalence and correlates of eating disorders in a large, reprefentative sample of US adolescents. Design Cross-sectional survey of adolescents with face-to-face interviews using a modified version of the Composite International Diagnostic Interview. Setting Combined household and school adolescent samples. Participants Nationally representative sample of 10 123 adolescents aged 13 to 18 years. Main Outcome Measures Prevalence and correlates of eating disorders and subthreshold conditions. Results Lifetime prevalence estimates of anorexia nervosa, bulimia nervosa, and binge-eating disorder were 0.3%, 0.9%, and 1.6%, respectively. Important differences were observed between eating disorder subtypes concerning sociodemographic correlates, psychiatric comorbidity, role impairment, and suicidality. Although the majority of adolescents with an eating disorder sought some form of treatment, only a minority received treatment specifically for their eating or weight problems. Analyses of 2 related subthreshold conditions suggest that these conditions are often clinically significant. Conclusions Eating disorders and subthreshold eating conditions are prevalent in the general adolescent population. Their impact is demonstrated by generally strong associations with other psychiatric disorders, role impairment, and suicidality. The unmet treatment needs in the adolescent population place these disorders as important public health concerns.

- Epidemiology of Eating Disorders: Incidence, Prevalence and Mortality Rates (2012, background): “3% in 13-18-year-old females as well as males.(47) The female-to-male ratio in these studies is considerably lower than the 10:1 ratio found in the Finnish twin study and as reported in previous reviews,(2,14,41) which could be due to differences in methodology and small numbers of cases with eating”
