Abstract
BACKGROUND: Patients undergoing gastric bypass lose substantial weight, but 20% regain weight starting at 2 years after surgery. Our objective was to identify behavioral predictors of weight regain after laparoscopic Roux-en-Y gastric bypass (LRYGB). METHODS: We retrospectively surveyed 197 patients for factors predictive of weight regain (≥15% from lowest weight to weight at survey completion). Consecutive patients who had bariatric surgery from 1/2003 through 12/2008 were identified from an existing database. Response rate was 76%, with 150 patients completing the survey. RESULTS: Follow-up after LRYGB was 45.0 ± 12.7 months, 22% of patients had weight regain. After controlling for age, gender, and follow-up time, factors associated with weight regain included low physical activity (odds ratio (OR) 6.92, P = 0.010), low self-esteem (OR 6.86, P = 0.008), and Eating Inventory Disinhibition (OR 1.30, P = 0.029). CONCLUSIONS: Physical activity, self-esteem, and maladaptive eating may be associated with weight regain after LRYGB. These factors should be addressed in prospective studies of weight loss following bariatric surgery, as they may identify patients at risk for weight regain who may benefit from tailored interventions.
