减肥手术候选人在中等至高强度体力活动（≥3代谢当量[METs]）上花费的时间很少。这项研究考察了(1)与低强度活动（1.5 - 2.9 METs）相比，他们有多少剩余时间花在久坐行为上（SB<1.5 METs）；(2)久坐时间是否因BMI而异。使用SenseWear Pro2臂带检测42例（BMI=49.5±7.9 kg/m2）手术患者每天在SB中度过的时间（小时，%）。根据BMI对参与者进行分层，以评估肥胖程度与SB之间的关系。参与者佩戴臂章的时间分别为5.4±0.7天和13.3±1.7小时/天。平均81.4%（10.9±2.1小时/天）的时间是在SB中度过的。BMI≥50的参与者每天在SB中的时间比BMI 35-49.9的参与者多近1小时（p=0.01）。减肥手术患者超过80%的时间处于SB状态。减少SB可能有助于增加这些患者的身体活动。
Bariatric surgery candidates spend very little time in moderate-to-vigorous intensity physical activity (≥3 metabolic equivalents [METs]). This study examined (1) how much of their remaining time is spent in sedentary behaviors (SB<1.5 METs) compared to light-intensity activities (1.5–2.9 METs) and (2) whether sedentary time varies by BMI. Daily time (hours, %) spent in SB was examined in 42 surgery candidates (BMI=49.5±7.9 kg/m2) using the SenseWear Pro2 Armband. Participants were stratified by BMI to assess the relationship between degree of obesity and SB. Participants wore the armband for 5.4±0.7 days and 13.3±1.7 h/day. On average, 81.4% (10.9±2.1 h/day) of this time was spent in SB. Participants with BMI≥50 spent nearly an hour more per day in SB than those with BMI 35–49.9 (p=0.01). Bariatric surgery candidates spend over 80% of their time in SB. Reducing SB may help to increase physical activity in these patients.
