Abstract

Objective: To evaluate change in sedentary behavior (SB) and physical activity (PA) over 3 years following bariatric surgery.

Methods: A subset of participants in an observational study (n = 473 of 2,458; 79% female, median body mass index 45 kg m(-2) ) wore an activity monitor presurgery and at 1-3 annual postsurgery assessments.

Results: Over the first year, on average, sedentary time decreased from 573 (95% CI: 563-582) to 545 (95% CI: 534-555) min days(-1) and moderate- to vigorous-intensity PA (MVPA) increased from 77 (95% CI: 71-84) to 106 (95% CI: 98-116) min week(-1) , or 7 (95% CI: 5-10) to 24 (95% CI: 18-29) min week(-1) in MVPA bouts ≥10 min. There were no changes in these parameters from years 1 to 3 (P for all > 0.05). The percentage of participants achieving ≥150 min week(-1) of bout-related MVPA was not different at year 3 [6.5% (95% CI: 3.1-12.7)] vs. presurgery [3.4% (95% CI: 1.8-5.0); P = 0.45]. Most participants followed SB and PA trajectories that paralleled mean change and were consistent with their presurgery position in relation to the group.

Conclusions: On average, bariatric surgical patients make small reductions in SB and increases in PA during the first postsurgery year, which are maintained through 3 years. Still, postsurgery PA levels fall short of PA guidelines for general health or weight control.
