Background and Objective: Bariatric surgeries are among the most effective methods for treating obesity. A key postoperative challenge is insufficient weight loss or weight regain, which may be associated with eating disorders after surgery. This study was conducted to evaluate the prevalence of binge eating (BE) disorder following bariatric surgery in Gorgan, Iran.
Methods: This descriptive analytical study was performed on 133 patients (mean age = 42.65±9.78 years) who underwent bariatric surgery performed by a single surgeon for the treatment of obesity at Dr. Mousavi Hospital in Gorgan, Iran, during 2013-2019. Patients were invited for an interview, physical examination, and to complete a questionnaire via a phone call. After obtaining informed consent, participants' current height and weight were measured using a standard method, and the Binge Eating Disorder Scale (BEDS) was completed. Variables, such as the type of surgery and preoperative height and weight were extracted and recorded from patients' medical records. The prevalence of BE disorder was compared between patients with and without weight regain.
Results: Out of 133 participants, 44 (33.1%) experienced weight regain. Moderate or severe BE disorder was identified in 59 individuals (44.4%). The prevalence of BE disorder was significantly higher in patients with weight regain compared to those without (P<0.05). The odds of ratios (ORs) for weight regain were 3.7 and 3.9 times higher in individuals with moderate and severe BE disorder, respectively, compared to those without the disorder. No statistically significant association was observed between BE disorder and variables, such as gender, education, occupation, and marital status. However, among individuals who experienced weight regain, being a housewife had a statistically significant association with the disorder (P<0.05).
Conclusion: BE disorder is a significant factor in patient weight regain in the years following surgery, particularly among housewives.
