Affective disorder in the families of women with normal weight bulimia

Abstract

The authors determined the lifetime prevalence of affective disorder in the first- and second-degree relatives, excluding children, of 27 bulimic women who had never had anorexia nervosa and 27 women with no history of an eating disorder. Family diagnoses were made blind to the proband's diagnosis. The prevalence of affective disorder was 9% in the relatives of the bulimic probands and 10% in the relatives of the control probands, a nonsignificant difference. These findings are in contrast to reports of an increased prevalence of affective disorder in the relatives of patients with anorexia nervosa.
