减肥手术的病人醒着的时候大部分时间都是坐着的。然而，很少有人知道他们的久坐时间（ST）的积累模式，以及是否更长的ST与较低的体力活动（PA），独立于总ST，或肥胖的严重程度。描述肥胖患者术前ST段延长的变异性，并评估与PA和体重状态相关的“延长”模式的重要性。美国两所大学医院诊所。成年患者（n = 76）术前佩戴腕部加速计10天。ST和时间花费在轻和中度到有力的PA使用验证阈值确定。计算≥30次连续ST分钟发作中累积的总ST百分比，并根据该值将参与者分为低、中和高“峰值”。研究ST段延长与PA和肥胖的关系。平均而言，参与者每天累积的ST平均值±标准差为10.5 ± 2.1小时，其中30%延长（延长组：低= 7.2%-24.5%，中= 24.5%-33.0%，高= 34.0%-52.6% ST ≥30分钟的发作）。调整包括总ST在内的协变量后，高血压患者每天的轻度PA分钟数较少（P < .01），ST延长的百分比较高，与符合每周≥150分钟中度至剧烈PA分钟的国家指南的可能性较低有关（P = .012）。肥胖程度高的人比肥胖程度低的人有更严重的肥胖（P <0.05）。在肥胖患者中，在长时间发作中积累更大百分比的ST似乎与PA和肥胖严重程度呈不良相关。未来的研究应确定是否中断延长ST与短暂休息，可以有利地修改PA和体重在这一人群。(Surg肥胖相关疾病2020;16：562-567。© 2020美国减肥外科学会。
Bariatric surgery patients spend much of their waking time sedentary. Yet, little is known about their patterns of accumulation of sedentary time (ST) and whether more prolonged ST is associated with lower physical activity (PA), independent of total ST, or obesity severity. To characterize variability in prolonged ST among bariatric patients preoperatively and assess the importance of a “prolonger” pattern in relation to PA and weight status. Two university hospital clinics, United States. Adult patients (n = 76) wore a wrist-based accelerometer for 10 days preoperatively. ST and time spent in light and moderate-to-vigorous PA was determined using validated thresholds. Percent of total ST accumulated in ≥30-consecutive ST minute bouts was calculated, and participants were trichotomized into low, medium, and high “prolongers” based on this value. The associations of prolonged ST with PA and obesity were examined. On average, participants accumulated a mean ± standard deviation of 10.5 ± 2.1 hours of ST per day, 30% of which was prolonged (prolonger groups: low = 7.2%–24.5%, medium = 24.5%–33.0%, and high = 34.0%–52.6% of ST in ≥30-min bouts). Adjusting for covariates including total ST, high prolongers had fewer light PA minutes per day (P < .01), and a greater percentage of prolonged ST related to lower likelihood of meeting the national guideline of ≥150 moderate-to-vigorous PA minutes per week (P = .012). High (versus low) prolongers had more severe obesity (P < .05). Accumulating a greater percentage of ST in prolonged bouts appears to be adversely related to PA and obesity severity among bariatric patients. Future research should determine whether interrupting prolonged ST with brief breaks can favorably modify PA and weight in this population.
