Abstract

<abstract abstract-type="main"> <title> <x xml:space="preserve">Abstract</x> </title> <sec id="oby20988-sec-0001" sec-type="section"> <title>Objective</title> <p>To examine the impact of a pre‐bariatric surgery physical activity intervention (PAI), designed to increase bout‐related (≥10 min) moderate to vigorous PA (MVPA), on health‐related quality of life (HRQoL).</p> </sec> <sec id="oby20988-sec-0002" sec-type="section"> <title>Methods</title> <p>Analyses included 75 adult participants (86.7% female; BMI = 45.0 ± 6.5 kg m<sup>−2</sup>) who were randomly assigned to 6 weeks of PAI (<italic>n</italic> = 40) or standard pre‐surgical care (SC; <italic>n</italic> = 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.</p> </sec> <sec id="oby20988-sec-0003" sec-type="section"> <title>Results</title> <p>PAI increased bout‐related MVPA from baseline to post‐intervention (4.4 ± 5.5 to 21.0 ± 21.4 min day<sup>−1</sup>) versus no change (7.9 ± 16.6 to 7.6 ± 11.5 min day<sup>−1</sup>) for SC (<italic>P</italic> = 0.001). PAI reported greater improvements than SC on all SF‐36 physical and mental scales (<italic>P</italic> < 0.05), except role‐emotional. In PAI, better baseline scores on the physical function and general health scales predicted greater bout‐related MVPA increases (<italic>P</italic> < 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 (<italic>P</italic> < 0.05).</p> </sec> <sec id="oby20988-sec-0004" sec-type="section"> <title>Conclusions</title> <p>Increasing PA preoperatively improves physical and mental HRQoL in bariatric surgery candidates. Future studies should examine whether this effect improves surgical safety, weight loss outcomes, and postoperative HRQoL.</p> </sec> </abstract>
