Bulimia and anorexia nervosa in winter depression: lifetime rates in a clinical sample.

Symptoms of an eating disorder (hyperphagia, carbohydrate craving, and weight gain) are characteristic of wintertime depression. Recent findings suggest that the severity of bulimia nervosa peaks during fall and winter months, and that persons with this disorder respond to treatment with bright artificial light. However, the rates of eating disorders among patients presenting for the treatment of winter depression are unknown. This study was undertaken to determine these rates among 47 patients meeting the DSM-III-R criteria for major depression with a seasonal pattern. All were evaluated using standard clinical interviews and the Structured Clinical Interview for DSM-III-R. Twelve (25.5%) patients met the DSM-III-R criteria for an eating disorder. Eleven patients had onset of mood disorder during childhood or adolescence. The eating disorder followed the onset of the mood disorder. Clinicians should inquire about current and past symptoms of eating disorders when evaluating patients with winter depression.
