Objective The authors examined the prevalence of binge eating disorder (BED), partial binge eating syndrome, and night binge eating syndrome in subjects with bipolar disorder (BD). Method: Sixty‐one subjects in whom BD was established using DSM‐III‐R criteria received a semistructured clinical interview including a detailed description of binge eating behavior and of night binge eating. Frequencies were compared to prevalence estimates in community samples. Results: Eight subjects (13%) met DSM‐IV criteria for the diagnosis of BED. An additional 15 subjects (25%) exhibited a partial binge eating syndrome. These two otherwise identical groups of binge eaters were separated only by the DSM‐IV frequency criterion. The rates found were higher than rates found in community samples. Ten subjects reported night binge eating in addition to their usual binge eating behavior. This occurred consistently between 2:00 and 4:00 a.m. Conclusions: Possible underlying mechanisms for the high frequency of binge eating among bipolar subjects are discussed including a model of serotonin‐mediated self‐modulation of mood. The finding of two groups of binge eaters separated only by the frequency criterion raises questions as to whether the frequency criterion as presently defined in DSM‐IV is valid or should be modified. © 1996 by John Wiley & Sons, Inc.
