Psychiatric Disorders Associated with the Onset and Persistence of Bulimia Nervosa and Binge Eating Disorder During Adolescence

A prospective longitudinal study was conducted to investigate whether anxiety, depressive, personality, or substance use disorders increase risk for onset of bulimia nervosa (BN) or binge eating disorder (BED) during adolescence. Axis I and II psychiatric disorders were assessed in a primary care sample of 201 adolescents. Axis I disorders were reassessed 10 months later. Youths with dysthymic disorder were at elevated risk for the onset or recurrence of BN or BED after preexisting psychiatric disorders were controlled statistically. Problems with depression or anxiety tended to precede the onset of eating problems. In addition, youths with eating disorder symptoms were at elevated risk for the onset or recurrence of depressive disorders. These findings suggest that adolescents with chronic depressive symptoms may be at elevated risk for the development of BN or BED, and that adolescents with eating disorder symptoms may be at elevated risk for the development of depressive disorders.
