Depression as a correlate of starvation in patients with eating disorders.

The relationship between depressive symptoms and starvation, reflected by body weight and biochemical parameters, was investigated in 64 patients fulfilling DSM-III criteria for anorexia nervosa or bulimia. Multiple regression analysis revealed significant effects of body weight and beta-hydroxybutyric acid, respectively, on such specific depressive symptoms as depressed or dysphoric mood when controlling for severity of psychopathology of the eating disorder.
