回顾性（问卷调查）和前瞻性（5天日记）的睡眠自我报告，从209名妇女在怀孕第三个三个月。平均而言，这些女性睡眠时间为465分钟，大约需要20分钟才能入睡，并且在最初的睡眠开始后醒了30分钟，平均醒了2.6次。睡眠效率约为89%。回顾性和前瞻性报告之间的显着差异仅在入睡后清醒的分钟数和睡眠效率上。然而，这些差异很小。回顾性和前瞻性报告仅中度相关。这些结果与以前使用多导睡眠图对孕妇进行的小规模研究报告的值没有明显差异，表明自我报告是有效的。研究结果表明，睡眠参数在怀孕的第三个三个月期间并不像人们普遍认为的那样受到不利影响。
Retrospective (questionnaire) and prospective (5-day diary) self-reports of sleep were obtained from 209 women during the 3rd trimester of pregnancy. On average, the women slept for 465 min, took around 20 min to get to sleep, and were awake for just over 30 min after initial sleep onset having woke 2.6 times on average. Sleep efficiency was around 89%. Significant differences were found between retrospective and prospective reports only on the number of minutes awake after sleep onset and on sleep efficiency. However, these differences were small. Retrospective and prospective reports were only moderately correlated. These results were not markedly different from values reported in much smaller, previous studies of pregnant women using polysomnography, suggesting that the self-reports were valid. The findings suggest that sleep parameters are not as adversely affected during the 3rd trimester of pregnancy as is generally believed.
