Abstract

Recent research has provided evidence that bariatric surgery maximizes long-term weight loss in patients with severe obesity. However, a substantial number of patients experience poor weight loss outcome and weight regain over time. Post-operative behavioural management may facilitate long-term weight control in bariatric surgery population. The objective of this systematic review and meta-analysis was to determine the effects of post-operative behavioural management on weight loss following bariatric surgery. Eligible articles were systematically searched in electronic databases. Among the 414 citations, five randomized controlled trials, two prospective and eight retrospective cohort trials analysing behavioural lifestyle interventions and support groups fulfilled the inclusion criteria. The main finding is that behavioural management had a positive effect on weight loss following surgery. In 13 studies, patients receiving behavioural management had greater weight loss than patients receiving usual care or no treatment. A meta-analysis of five randomized controlled trials suggests greater weight loss in patients with behavioural lifestyle interventions compared with control groups. Post-operative behavioural management has the potential to facilitate optimal weight loss following bariatric surgery, but conclusions were limited by the small and heterogeneous samples of studies. A more rigorous empirical evaluation on its clinical significance is warranted to improve effectiveness of bariatric surgery.
