Behavioural interventions appear to improve weight loss at 12 months after bariatric surgery .
Background Significant , sustained weight loss through conventional , non-surgical interventions is often unattainable for people with severe obesity ( e.g. BMI ≥40 or ≥35 kg/m2 with co-morbidities ) .
Bariatric surgery is effective in treating severe obesity , but surgery alone without additional behaviour change management may not result in optimum long-term weight loss and maintenance .
This systematic review and meta- analysis of r and omised controlled trials evaluated the effectiveness of lifestyle interventions before and /or after bariatric surgery .
Optimizing long-term weight control after bariatric surgery: a pilot study.
BACKGROUND Although bariatric surgery is associated with significant overall weight loss , many patients experience suboptimal outcomes . Our objective was to document the preliminary efficacy of a behavioral intervention for bariatric surgery patients with relatively poor long-term weight loss and to explore the factors related to outcome at an academic medical center in the United States . METHODS Patients with a body mass index ( BMI ) ≥ 30 kg/m(2 ) who had undergone bariatric surgery ≥ 3 years before study entry and had < 50 % excess weight loss were enrolled . The participants were r and omly assigned to a 6-month behavioral intervention or wait list control group . The assessment s were conducted at baseline ( before intervention ) and 6 months ( after intervention ) and 12 months ( 6-mo follow-up ) . RESULTS On average , the participants ( n = 36 ) had undergone surgery 6.6 years before study entry . The average age was 52.5 ± 7.1 years , and the BMI was 43.1 ± 6.2 kg/m(2 ) ; most participants were women ( 75 % ) and white ( 88.9 % ) . The intervention patients had a greater percentage of excess weight loss than did the wait list control group at 6 ( 6.6 % ± 3.4 % versus 1.6 % ± 3.1 % ) and 12 ( 5.8 % ± 3.5 % versus .9 % ± 3.2 % ) months . However , the differences were not significant and the results varied . The intervention patients with more depressive symptoms ( P = .005 ) and less weight regain before study entry ( P = .05 ) experienced a greater percentage of excess weight loss . CONCLUSION Behavioral intervention holds promise in optimizing long-term weight control after bariatric surgery . More research is needed on when to initiate the intervention and to identify which patients will benefit from this type of approach
