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 .
Comprehensive behavioral-motivational nutrition education improves depressive symptoms following bariatric surgery: a randomized, controlled trial of obese Hispanic Americans.
OBJECTIVE To evaluate the effect of 2 post-bariatric support interventions on depressive symptoms of Hispanic Americans treated with gastric bypass for morbid or severe obesity . DESIGN / SETTING Prospect i ve r and omized , controlled trial conducted in a laparoscopic institution . PARTICIPANTS / INTERVENTIONS During the Phase 1 clinical trial ( from preoperative evaluation to 6 months after surgery ) , all participants received st and ard care . During Phase 2 ( 6 - 12 months after surgery ) , participants were r and omly assigned to receive either st and ard care ( n = 72 ) or comprehensive support ( n = 72 ) . Comprehensive group participants received 6 educational sessions focused on behavior change strategies and motivation with nutrition counseling . MAIN OUTCOME MEASURES Depression scores and weight change over time . ANALYSIS Independent sample s t tests and regression analysis assessed relationships among depression scores and excess weight loss . RESULTS Participants receiving behavioral-motivational intervention scored significantly lower on Beck 's Depression Inventory question naire scores than those receiving st and ard care . For those with depressive symptoms at r and omization , 24 % of participants who received the comprehensive intervention reported no depressive symptoms at 12 months after surgery , compared with 6 % of those who received st and ard care ( P < .001 ) . Patients ' depressive mood improvement was significantly and positively associated with excess weight loss and attendance at educational sessions ( P < .001 ) . CONCLUSIONS AND IMPLICATION S Findings support the importance of post-bariatric comprehensive behavioral-motivational nutrition education for decreasing risk for depression and improving weight loss
