Abstract Objective—We previously reported that preoperative binge eating disorder (BED) did not attenuate weight loss 12 months after bariatric surgery. This report extends our prior study by examining weight loss at 24 months.
Author Manuscript
Methods—We used a modified intention-to-treat (ITT) population to compare 24-month changes in weight among 59 participants treated with bariatric surgery, determined preoperatively to be free of a current eating disorder, with changes in 33 surgically-treated participants with BED. Changes were also compared with 49 individuals with obesity and BED who sought lifestyle modification for weight loss. Analyses included all available data points and were adjusted for covariates. Results—At month 24, surgically-treated patients with BED preoperatively lost 18.6% of initial weight, compared with 23.9% for those without BED (p=0.049). (Mean losses at month 12 had been 21.5% and 24.2%, respectively; p=0.23.) Participants with BED who received lifestyle
