Preoperative and post-operative intensive interventions improved symptoms of depression and anxiety , quality of life , diastolic blood pressure , and resting heart rate but not lipids or glycaemic measures .
This systematic review and meta- analysis of intervention studies aims to evaluate the effect of preoperative and /or post-operative support for adults who elect bariatric surgery delivered by a multidisciplinary team ( MDT )  on post-operative body composition , mental health , co-morbidities , quality of life , and side effects .
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
