Affective and Anxiety Disorders in the Long-Term Follow-up of Anorexia Nervosa

Abstract

This study investigated the incidence and onset of affective and anxiety disorders in women who were diagnosed with anorexia nervosa five to fourteen years earlier. Based on the clinical outcome of anorexia nervosa, patients were classified as asymptomatic, improved or symptomatic. Affective and anxiety disorders were assessed by a structured psychiatric interview (Diagnostic Interview Schedule). Results indicated that affective and anxiety disorders developed frequently, regardless of outcome of anorexia nervosa. Major depression and anxiety disorders developed before the eating disorder in one-half and three-quarters of these cases respectively. The symptomatic group had a significantly higher incidence of anxiety disorders prior to the development of their eating disorder compared with the asymptomatic group.
