Prevalence of eating disorders in the psychiatric emergency room.

A random sample of 143 patients from a centralized psychiatric emergency service with a catchment area of one million people was studied. A two-stage interview was conducted for diagnosis of DSM-III-R eating disorders. Of those reporting active bingeing, 14.5% were men, and 22.4% were women. No cases of anorexia nervosa were discovered. Bulimia nervosa was diagnosed in 3.0% of the women and 2.6% of the men. Race and marital status were unrelated to bingeing or to any eating disorder diagnosis. Many patients never had discussed their eating behaviors before with a therapist.
