Inactivity and weight regain are serious problems post-bariatric surgery. Nearly half of waking time is spent at work, representing an opportunity to accumulate physical activity and help avoid weight regain.
The purpose of this study is to evaluate potential differences in physical activity and sedentary time by employment status post-bariatric surgery.
A total of 48 adults (employed (n = 19), unemployed (n = 29)) aged 50.7 ± 9.4 years, BMI = 34.4 ± 10.1 kg/m, and 10 ± 3 years post-surgery participated. ActivPAL accelerometers measured transitions, steps, and sedentary time for 7 days.
Participants worked on average 8.7 ± 1.8 h/day. Twenty-one percent of employed met step/day guidelines on work-days compared to 10% of unemployed. Employed persons transitioned from sitting-to-standing more on work-days (58.6 ± 17.8) than unemployed (45.0 ± 15.4). Employment status did not influence activity or sedentarism on weekend/non-working-days.
Employment status may be associated with meaningful improvements in activity post-bariatric surgery.
术后缺乏运动和体重反弹是减肥手术后的严重问题。近一半的清醒时间是在工作中度过的，这为增加身体活动量和避免体重反弹提供了契机。
本研究旨在评估减肥手术后不同就业状况人群在身体活动和久坐时间方面的潜在差异。
共有48名年龄为50.7±9.4岁、BMI为34.4±10.1kg/m²且术后10±3年的成年人参与研究（其中就业者19名，失业者29名）。使用ActivPAL加速度计测量7天内的身体活动转换、步数和久坐时间。
参与者平均每天工作8.7±1.8小时。工作日中，21%的就业者达到了每日步数指南要求，而失业者中这一比例为10%。就业者在工作日从坐姿转换为站姿的次数（58.6±17.8次）多于失业者（45.0±15.4次）。就业状况对周末/非工作日的身体活动或久坐行为没有影响。
就业状况可能与减肥手术后身体活动的显著改善有关。
