比较不同的体动记录评分设置与多导睡眠图（PSG）的1晚总睡眠时间（TST），睡眠效率（SE），入睡后觉醒（WASO），和入睡潜伏期（SOL）的健康孕妇在怀孕6和7个月。使用病例对照研究数据的次要分析。美国中西部的一所大型大学附属医院。共招募了78名孕妇，其中38名健康孕妇无并发症。受试者在睡眠中心进行了整夜PSG评估，同时佩戴活动记录仪（Minimitter; Philips Respironics，Andover，MA）。两种器械的睡眠参数包括TST、SE、WASO和SOL。使用四种评分设置从体动记录仪获得这些参数。Bland-Altman检验用于评估独立于体动记录仪和PSG的睡眠变量之间的一致性。默认评分设置（10 × 40）产生的结果与PSG有显著差异（P <0.01）。活动阈值为10（10 × 10）的睡眠开始/结束的10分钟移动的/移动的分钟产生的TST、SE和WASO估计值最接近PSG产生的估计值。当使用该设置时，PSG和腕动记录仪评估的TST、SE和WASO之间的平均差异分别为-1.9分钟、-0.4%和7.4分钟。当使用10和15 im移动的/移动的分钟作为睡眠开始/结束时，PSG和腕动描记术评估的SOL之间的差异约为4至5分钟。本研究的结果不支持在孕妇中使用默认活动记录仪设置。相比之下，10 × 10的评分设置提供了最大的一致性和最小的偏差相比，PSG的睡眠测量。建议在由孕妇组成的研究中使用10 × 10评分设置。
To compare different actigraphy scoring settings with polysomnography (PSG) for 1 night of total sleep time (TST), sleep efficiency (SE), wake after sleep onset (WASO), and sleep onset latency (SOL) in healthy pregnant women between 6 and 7 months of gestation. Secondary analysis using data from a case-control study. A large university-affiliated hospital in the Midwestern United States. A total of 78 pregnant women were recruited, among which 38 healthy women with uncomplicated pregnancies were included for this analysis. Participants had an overnight PSG assessment at a sleep center while simultaneously wearing an actigraph (Minimitter; Philips Respironics, Andover, MA). Sleep parameters from both devices included TST, SE, WASO, and SOL. Four scoring settings were used to obtain these parameters from actigraphy. Bland-Altman tests were used to evaluate the agreement between sleep variables scored independently from actigraphy and PSG. The default scoring setting (10-by-40) yielded significantly different results from the PSG (P < .01). The 10 immobile/mobile minutes for sleep onset/end with an activity threshold of 10 (10-by-10) produced estimations of TST, SE, and WASO closest to those produced by PSG. When this setting was used, the mean differences between PSG- and actigraphy-assessed TST, SE, and WASO were −1.9 minutes, −0.4%, and 7.4 minutes. When the 10 and 15 immobile/mobile minutes for sleep onset/end were used, the difference between PSG- and actigraphy-assessed SOL was approximately 4 to 5 minutes. Findings from this study do not support the use of default actigraph settings in pregnant women. In contrast, the 10-by-10 scoring setting provided the greatest agreement and least bias in comparison with PSG for sleep measurements. The 10-by-10 scoring setting is recommended to be used in studies consisting of pregnant women.
