Background
Prior studies have reached contradictory conclusions concerning whether binge eating disorder (BED) is associated with greater psychopathology in extremely obese patients who seek bariatric surgery. This study used the Structured Clinical Interview for DSM-IV Diagnoses (SCID) to compare rates of axis I psychopathology in surgery candidates who were determined to have BED or to be currently free of eating disorders. The relationship of BED to other psychosocial functioning and weight loss goals also was examined.
Methods
One hundred ninety five bariatric surgery patients completed the Weight and Lifestyle Inventory and the Beck Depression Inventory-II (BDI-II) and were later administered the Eating Disorder Examination. Of these 195, 44 who were diagnosed with BED, and 61 who were currently free of eating pathology, completed a telephone-administered SCID.
Results
Significantly more BED than non-BED participants had a current mood disorder (27.3% vs. 4.9%, p = 0.002) as well as a lifetime history of this condition (52.3% vs. 23.0%, p = 0.003). More BED than non-BED participants also had a current anxiety disorder (27.3% vs. 8.2%, p = 0.014) and lifetime anxiety disorder (36.4% vs. 16.4%, p = 0.019). BED also was associated with greater symptoms of depression, as measured by the BDI-II, as well as with lower self-esteem. BED and non-BED groups, however, did not differ in their desired weight loss goals following surgery.
Conclusions
The present findings indicate that the presence of BED, in patients who seek bariatric surgery, is associated with an increased prevalence of axis I psychopathology, beyond the already elevated rate observed with severe (i.e., class III) obesity.
