In studies that have reported device-based measures of sedentary time (ST) in people with chronic obstructive pulmonary disease (COPD), we explored if the monitor type and monitor wear time moderated the estimate of this measure. Five electronic databases were searched in January 2021. Studies were included if >70% of participants had stable COPD, and measures of ST (min/day) were collected using wearable technology. Meta-regression was used to examine the influence of moderators on ST, monitor type, and wear time. The studies identified were a total of 1153, and 36 had usable data for meta-analyses. The overall pooled estimate of ST (mean [95% CI]) was 524 min/day [482 to 566] with moderate heterogeneity among effect sizes (I2 = 42%). Monitor wear time, as well as the interaction of monitor wear time and monitor type, were moderators of ST (p < 0.001). The largest difference (−318 min; 95% CI [−212 to −424]) was seen between studies where participants wore a device without a thigh inclinometer for 24 h (and removed sleep during analysis) (675 min, 95% CI [589 to 752]) and studies where participants wore a device with a thigh inclinometer for 12 h only (356 min; 95% CI [284 to 430]). In people with COPD, the monitor wear time and the interaction of the monitor wear time and the monitor type moderated the estimate of ST.
在报告了慢性阻塞性肺疾病（COPD）患者基于设备的久坐时间（ST）测量结果的研究中，我们探讨了监测器类型和监测器佩戴时间是否会影响该测量结果的估计。2021年1月检索了五个电子数据库。纳入的研究要求超过70%的参与者患有稳定的COPD，并且使用可穿戴技术收集ST（分钟/天）的测量数据。采用Meta回归分析来检验调节因素对ST、监测器类型和佩戴时间的影响。共识别出1153项研究，其中36项有可用于Meta分析的数据。ST的总体合并估计值（均值[95%CI]）为524分钟/天[482至566]，效应量之间存在中度异质性（I² = 42%）。监测器佩戴时间以及监测器佩戴时间与监测器类型的交互作用是ST的调节因素（p < 0.001）。在参与者佩戴无大腿倾斜计的设备24小时（分析时去除睡眠时间）的研究（675分钟，95%CI[589至752]）和参与者仅佩戴有大腿倾斜计的设备12小时的研究（356分钟；95%CI[284至430]）之间，观察到最大差异（-318分钟；95%CI[-212至-424]）。在COPD患者中，监测器佩戴时间以及监测器佩戴时间与监测器类型的交互作用会影响ST的估计。
