Binge Eating Disorder, Depression and Anxiety, and Weight Gain and Increased BMI After Five Years of Bariatric Surgery

Abstract

ObjectivesAnalyze the influence of Binge Eating Disorder (BED) and symptoms of depression and anxiety on anthropometric and body composition changes over five years after bariatric surgery in patients with obesity.MethodsEvaluation of 118 individuals undergoing bariatric surgery, divided into two groups: Group 1: individuals with BED; Group 2: individuals without BED. The individuals were submitted to anthropometric and body composition evaluation, and analysis of the presence of BED, depression, and anxiety according to the DSM-V and using validated questionnaires. The Kolmogorovi-Smirnov, t-test, Fisher’s, chi-square, and ANOVA were used for statistical analysis.ResultsThe groups with BED (N=61, 51,7%) and without BED (N=57, 48,3%) did not differ from each other for all sociodemographic assessed variables (p>0.05) and had similar changes in waist circumference and body composition over five years after bariatric surgery (p>0.05). On the other hand, only patients with BED had severe depression (13,11%, p=0.0079) and had a higher frequency of moderate (22.95%, p=0.0022) and severe (14.75%, p=0.0022) anxiety in the preoperative period of bariatric surgery. In addition, only the group with BED had increased weight and increased BMI in the fifth year after bariatric surgery (p<0.05).ConclusionPatients with BED had more intense symptoms of depression and anxiety, and this disorder may reappear in the postoperative period of bariatric surgery and contribute to weight gain and an increase in BMI.Level of evidence: III (evidence obtained from case-control analytic study).
