To investigate sleep duration and sleep loss during antenatal period and assess associative factors, including maternal characteristic and mood symptoms.
A cohort of 3038 women was enrolled. Self-reported sleep duration and sleep loss, the latter being calculated from preferred sleep need and actual sleep duration, were measured in early, mid- and late pregnancy, and at delivery. The associations with age, BMI, parity, education, smoking, napping, and depressive and anxiety symptoms were evaluated.
Sleep duration was longest in early pregnancy and shortest at delivery (7.93 h-7.76 h, p < 0.001). The proportion of short sleepers (< 6 h) increased from 1.4% to 5.9% throughout the studied period (p < 0.001). Mean sleep loss remained stable in early- and mid-pregnancy, lowering in late pregnancy (p < 0.001) and increasing again until delivery (p = 0.003). The number of women with notable sleep loss (> 2 h) was similar during the first three measurement points (9.4%, 8.9% and 9.5%), but increased until delivery (14.1%, p < 0.001). Older, multiparous, and more-depressive women slept less (p < 0.001, p < 0.001, p = 0.017). Women with higher BMI were more likely to sleep < 6 h in late pregnancy (p = 0.012). Multiparous, more-depressive, and higher-BMI women reported more sleep loss (p < 0.001, p < 0.001, p = 0.049).
We confirmed earlier reported decrease in sleep duration at the end of pregnancy. As a novel finding, we showed a notable increase in sleep loss during the last month of pregnancy. Various factors were associated with both short sleep and sleep loss, especially multiparity, napping and depressive symptoms.
研究产前睡眠时间和睡眠缺失情况，并评估包括产妇特征和情绪症状在内的相关因素。
本队列纳入了 3038 名女性。在孕早期、孕中期、孕晚期和分娩时测量了自我报告的睡眠时间和睡眠缺失情况，后者是通过偏好的睡眠时间和实际睡眠时间计算得出的。评估了年龄、BMI、产次、教育程度、吸烟、午睡、抑郁和焦虑症状与这些变量的相关性。
睡眠时间在孕早期最长，在分娩时最短（7.93 小时-7.76 小时，p<0.001）。在整个研究期间，短睡眠者（<6 小时）的比例从 1.4%增加到 5.9%（p<0.001）。在孕早期和孕中期，平均睡眠缺失量保持稳定，在孕晚期下降（p<0.001），然后在分娩时再次增加（p=0.003）。在前三项测量点，有明显睡眠缺失（>2 小时）的女性数量相似（9.4%、8.9%和 9.5%），但在分娩时增加（14.1%，p<0.001）。年龄较大、多产和抑郁程度较高的女性睡眠时间较少（p<0.001，p<0.001，p=0.017）。BMI 较高的女性在孕晚期更有可能睡眠<6 小时（p=0.012）。多产、抑郁程度较高和 BMI 较高的女性报告的睡眠缺失更多（p<0.001，p<0.001，p=0.049）。
我们证实了先前报道的妊娠末期睡眠时间减少的情况。作为一项新发现，我们显示了在妊娠最后一个月睡眠缺失显著增加。各种因素与短睡眠和睡眠缺失有关，尤其是多产、午睡和抑郁症状。
