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 .
Preoperative lifestyle intervention in bariatric surgery: a randomized clinical trial.
BACKGROUND Studies on the impact of presurgery weight loss and lifestyle preparation on outcomes following bariatric surgery are needed . OBJECTIVE To evaluate whether a presurgery behavioral lifestyle intervention improves weight loss through a 24-month postsurgery period . SETTING Bariatric Center of Excellence at a large , urban medical center . METHODS C and i date s for bariatric surgery were r and omized to a 6-month behavioral lifestyle intervention or to 6 months of usual presurgical care . The lifestyle intervention consisted of 8 weekly face-to-face sessions , followed by 16 weeks of face-to-face and telephone sessions before surgery ; the intervention also included 3 monthly telephone contacts after surgery . Assessment s were conducted 6 , 12 , and 24 months after surgery . RESULTS Participants who underwent surgery ( n = 143 ) were 90.2 % female and 86.7 % White . Average age was 44.9 years , and average body mass index was 47.5 kg/m(2 ) at study enrollment . At follow-up , 131 ( 91.6 % ) , 126 ( 88.1 % ) , 117 ( 81.8 % ) patients participated in the 6- , 12- , and 24-month assessment s , respectively . Percent weight loss from study enrollment to 6 and 12 months after surgery was comparable for both groups , but at 24 months after surgery , the lifestyle group had significantly smaller percent weight loss compared with the usual care group ( 26.5 % versus 29.5 % , respectively , P = .02 ) . CONCLUSIONS Presurgery lifestyle intervention did not improve weight loss at 24 months after surgery . The findings from this study raise questions about the utility and timing of adjunctive lifestyle interventions for bariatric surgery patients
