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 .
What variables are associated with successful weight loss outcomes for bariatric surgery after 1 year?
BACKGROUND Prior evidence indicates that predictors of weight loss outcomes after  gastric bypass surgery  fall within 5 domains : 1 ) presurgical factors , 2 ) postsurgical psychosocial variables ( e.g. , support group attendance ) , 3 ) postsurgical eating patterns , 4 ) postsurgical physical activity , and 5 ) follow-up at postsurgical clinic . However , little data exist on which specific behavioral predictors are most associated with successful outcomes ( e.g.,≥ 50 % excess weight loss ) when considering the 5 domains simultaneously . The objective of this study was to specify the behavioral variables , and their respective cutoff points , most associated with successful weight loss outcomes . METHODS Signal detection analysis evaluated associations between 84 pre- and postsurgical behavioral variables ( within the 5 domains ) and successful weight loss at ≥ 1 year in 274 postgastric bypass surgery patients .  RESULTS Successful weight loss was highest ( 92.6 % ) among those reporting dietary adherence of>3 on a 9-point scale ( median = 5 ) who grazed no more than once-per-day . Among participants reporting dietary adherence<3 and grazing daily or less , success rates more than doubled when highest lifetime body mass index was<53.7 kg/m(2 ) . Success rates also doubled for participants with dietary adherence = 3 if attending support groups . No variables from the physical activity or postsurgical follow-up domains were significant , nor were years since surgery . The overall model 's sensitivity = .62 , specificity = .92 . CONCLUSIONS To our knowledge , this is the first study to simultaneously consider the relative contribution of behavioral variables within 5 domains and offer clinicians an assessment algorithm identifying cut-off points for behaviors most associated with successful postsurgical weight loss . Such data may inform prospect i ve study design s and postsurgical interventions
