The Prevalence of Past 12-Month and Lifetime DSM-IV Eating Disorders by BMI Category in US Men and Women

ObjectiveThis study aims to determine whether the prevalence of lifetime and past 12-month DSM-IV eating disorders (ED) diagnoses differed by body mass index category among men and women in a general population sample. MethodsData from the Collaborative Psychiatric Epidemiology Surveys (n=12337 adults) were analysed using logistic regression. Analyses were conducted separately by gender. ResultsLifetime ED prevalence was 2.22% in men and 4.93% in women. In both genders, the prevalence of any lifetime and past 12-month ED, binge eating disorder and recurrent binge eating was highest among obese individuals. Among obese men and women, lifetime and past 12-month ED prevalence was highest among those with class III obesity. ConclusionEating disorders were most prevalent among high-weight individuals. This information is important for planning targeted public health ED and obesity prevention and intervention activities, as well as for informing the clinical care of obese individuals.
