Abstract
BACKGROUND: Eating disorders could be an important factor in the development of obesity, but psychiatric comorbidities are very heterogeneous in patients with obesity. Moreover, relationship between binge eating disorder and other psychiatric comorbidities is not clear. Our objective was to identify psychiatric comorbidity profiles of bariatric surgery candidates and to analyze the association between these profiles and binge-eating disorder. METHODS: Our sample consisted of bariatric surgery candidates (n = 92) with mean Body Mass Index at 41.3 ± 0.6 kg/m2. To construct profiles, we classified patients according to their psychiatric comorbidities using cluster analysis techniques. We used logistic regression modelling to analyze associations between the presence of binge-eating disorder and the psychiatric comorbidity profiles. RESULTS: We identified four profiles of psychiatric phenotypes. One of these profiles was not associated with any psychiatric disorder. Binge eating disorder was significantly associated with two profiles (p < 0.05): a profile with bipolar and obsessive-compulsive disorder (OR = 7.7 [1.7; 35.1]), and a profile with bipolar and panic disorder (OR = 20.7 [3.1; 137.5]). CONCLUSIONS: Our multidimensional approach identified certain profiles specifically associated with binge-eating disorder in patients with obesity seeking bariatric surgery. These results may lead to a better understanding of the relationship between obesity and psychiatric disorders.
