Various methods are employed to assess sleep in pregnant women, including self-report, sleep diary, and actigraphy. Unfortunately, the data are often contradictory, and interpretations are often inconsistent. The current aims are to compare subjective and objective sleep data in pregnant women collected longitudinally in early pregnancy.
In this secondary analysis of 104 pregnant women, sleep was collected via diary and actigraphy for 14 days during three separate occasions (10-12 weeks; 14-16 weeks; and 18-20 weeks). Sleep variables included wake after sleep onset (WASO), sleep efficiency (SE), bedtime/lights out, sleep onset latency (SL), and total sleep duration (TST). Repeated measures ANOVAs compared each sleep variable across Time and by Method of data collection, while controlling for parity and daytime naps.
Significant differences were noted for only the method of data collection for sleep component studied for WASO, F (1, 98) = 147.20, p < 0.001; SE, F (1, 98) = 129.41, p < 0.001); bedtime/lights out, F (1, 103) = 5.33, p < 0.05); and sleep duration, F (1, 104) = 182.75, p < 0.001). Significant variation was not seen in any variable across time-period.
There are substantial discrepancies between diary- and actigraphy-assessed sleep measures in pregnant women which is in alignment with previous literature. These data highlight that these methodologies assess different constructs. We contend that these data may be useful as a reference to compare high-risk women or those with sleep disorders. Using a multi-modal approach to identify sleep disturbance in pregnancy is likely a more clinically useful option.
评估孕妇睡眠的方法有多种，包括自我报告、睡眠日记和活动记录仪。遗憾的是，数据往往相互矛盾，解释也常常不一致。本研究旨在比较早孕期孕妇通过日记和活动记录仪连续收集的主观和客观睡眠数据。
本研究为 104 例孕妇的二次分析，在三个不同时间段（10-12 周、14-16 周和 18-20 周）通过日记和活动记录仪共收集 14 天的睡眠数据。睡眠变量包括睡眠后觉醒时间（WASO）、睡眠效率（SE）、上床/熄灯时间、入睡潜伏期（SL）和总睡眠时间（TST）。采用重复测量方差分析比较了每个睡眠变量在时间和数据收集方法上的差异，并控制了产次和日间小睡。
仅在研究的睡眠成分的 WSO、SE、上床/熄灯时间和睡眠持续时间的方法上观察到显著差异，F（1,98）=147.20，p<0.001；F（1,98）=129.41，p<0.001；F（1,103）=5.33，p<0.05；F（1,104）=182.75，p<0.001）。在任何变量中，时间段之间都没有明显的变化。
孕妇的日记和活动记录仪评估的睡眠测量之间存在显著差异，这与之前的文献一致。这些数据表明这些方法评估不同的结构。我们认为这些数据可作为比较高危妇女或睡眠障碍妇女的参考。使用多模态方法来识别妊娠期间的睡眠障碍可能是一种更具临床意义的选择。
