UNASSIGNED: Higher preoperative physical activity (PA) strongly predicts higher postoperative PA in @entity1104 ( @entity1104 ) @entity1 , providing rationale for preoperative PA interventions (PAIs). However, whether @entity2289 -related increases can be maintained postoperatively has not been examined. This study compared PA changes across pre- (baseline, post-intervention) and postoperative (6-month follow-up) periods in @entity1 randomized to 6 weeks of preoperative @entity2289 or standard care control (SC). Of 75 @entity1 initially randomized, 36 ( @entity2289 n=22; SC n=14) underwent @entity1104 . Changes in daily bout-related (   10-minute bouts) moderate-to-vigorous PA (MVPA) and steps were assessed via the SenseWear Armband monitor. @entity2289 received weekly counseling to increase walking exercise. Retention (86%) at postoperative follow-up was similar between groups. Intent-to-treat analyses showed that @entity2289 vs SC had greater increases across time (baseline, post-intervention, follow-up) in bout-related MVPA minutes/day (4.3  5.1, 26.3  21.3, 28.7  26.3 versus 10.4  22.9, 11.4  16.0, 18.5  28.2; P=0.013) and steps/day (5163  2901, 7950  3286, 7870  3936 versus 5163  2901, 5601  3368, 5087  2603; P<0.001). @entity2289 differed from SC on bout-related MVPA at post-intervention (P=0.016; d=0.91), but not follow-up (P=0.15; d=0.41), and steps at post-intervention (P=0.031; d=0.78) and follow-up (P=0.024; d=0.84). @entity2289 @entity1 maintained preoperative PA increases postoperatively. Findings support preoperative PAIs and research to test whether PA changes can be sustained and influence surgical outcomes beyond the initial postoperative period.International Journal of Obesity accepted article preview online, 27 December 2016. doi:10.1038/ijo.2016.237.
