Predictors of binge eating disorder and the impact on the quality of life in patients with severe obesity before bariatric surgery

Aim: Binge eating disorder (BED) is the most common eating disorder among bariatric surgery candidates. BED may pose a risk to postsurgical outcomes. This study aims to determine the predictors of BED and the impact on the psychiatric comorbidity and quality of life for patients with severe obesity who underwent bariatric surgery. Material and Methods: A total of 207 patients with severe obesity who underwent bariatric surgery were included. Face-to-face psychiatric interviews were performed to diagnose BED according to the DSM-5 diagnostic criteria. A sociodemographic and clinical form, Beck Depression Inventory (BDI), Beck Anxiety Inventory (BAI), body image scale (BIS), and short form-36 health survey were administered to the participants. Results: The rate of BED was determined as 30.9%. BED was associated with gender (female), lifetime suicidal ideation, previous suicide attempts, age of onset of obesity and the age of onset of dieting. Patients with BED presented with poor scores in BDI, BAI, BIS, and most domains of quality of life. Conclusion: Decreased BIS score, younger ages of onset for dieting, and previous suicide attempts predicted BED. The recognition of factors involved in the development of BED in patients with severe obesity will improve the effectiveness of treatment options for these patients
