Subclinical eating disorders and their comorbidity with mood and anxiety disorders in adolescent girls

The present study assesses the prevalence of subclinical eating disorders and examines their comorbidity with mood and anxiety disorders in a sample of adolescent girls. A DSM-III-R computerized self-reported interview was administered to 833 adolescent girls (mean age = 15.7 ± 0.5 years) from a population sample to assess the prevalence of subclinical eating disorders, major depression, dysthymia, separation anxiety, and generalized anxiety disorders. The prevalence of subclinical anorexia nervosa (restricting subtype) was 3.5%, 13.3% for weight concerns (restricting subtype), 3.8% for subclinical bulimia nervosa, and 10.8% for subclinical binge eating disorder. Girls with subclinical anorexia nervosa had a higher prevalence of separation anxiety diagnosis, and they reported significantly more major depressive and generalized anxiety symptoms compared with girls reporting no eating disorders. Girls with weight concerns reported significantly more major depressive, separation, and generalized anxiety symptoms compared with girls reporting no eating disorders. Girls with subclinical bulimia nervosa or binge eating disorder had a higher prevalence of mood disorders (major depression and dysthymia) compared with girls reporting no eating disorders. Furthermore, girls with subclinical bulimia nervosa or binge eating disorder also reported significantly more anxiety symptoms (separation anxiety and generalized anxiety) compared with girls reporting no eating disorders. In summary, adolescent girls suffering from subclinical eating disorders should be investigated concomitantly for mood and anxiety disorders while those suffering from mood and anxiety disorders should be investigated simultaneously for subclinical eating disorders.
