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 .
Exercise improves quality of life in bariatric surgery candidates: results from the Bari-Active trial.
OBJECTIVE To examine the impact of a pre-bariatric surgery physical activity intervention ( PAI ) , design ed to increase bout-related ( ≥10 min ) moderate to vigorous PA ( MVPA ) , on health-related quality of life ( HRQoL ) . METHODS Analyses included 75 adult participants ( 86.7 % female ; BMI = 45.0 ± 6.5 kg m(-2 ) ) who were r and omly assigned to 6 weeks of PAI ( n = 40 ) or st and ard pre-surgical care ( SC ; n = 35 ) .  PAI received 6 individual weekly counseling sessions to increase walking exercise . Participants wore an objective PA monitor for 7 days and completed the SF-36 Health Survey  at baseline and post-intervention to evaluate bout-related MVPA and HRQoL changes , respectively . RESULTS PAI increased bout-related MVPA from baseline to post-intervention ( 4.4 ± 5.5 to 21.0 ± 21.4 min day(-1 ) ) versus no change ( 7.9 ± 16.6 to 7.6 ± 11.5 min day(-1 ) ) for SC ( P = 0.001 ) . PAI reported greater improvements than SC on all SF-36 physical and mental scales ( P < 0.05 ) , except role-emotional . In PAI , better baseline scores on the physical function and general health scales predicted greater bout-related MVPA increases ( P < 0.05 ) , and greater bout-related MVPA increases were associated with greater post-intervention improvements on the physical function , bodily pain , and general health scales ( P < 0.05 ) . CONCLUSIONS Increasing PA preoperatively improves physical and mental HRQoL in bariatric surgery c and i date s. Future studies should examine whether this effect improves surgical safety , weight loss outcomes , and postoperative
