Symptoms of sleep disturbances are common among pregnant women and generally worsen across gestation. Pregnancy-related sleep disorders are not only associated with a poor quality of life of the affected mothers, but also with adverse perinatal outcomes, including perinatal depression, gestational diabetes, preeclampsia, and preterm birth. The current knowledge about the impact of sleep disorders during pregnancy largely derives from the results of sleep surveys conducted in various populations. However, the number of studies examining changes in objective sleep variables during pregnancy via polysomnography has progressively increased in recent years.

Here we systematically reviewed the polysomnographic studies available in the literature with the aim to describe the sleep pattern and to identify possible markers of sleep disruption in pregnant women.

Based on our analysis, subjective worsening of sleep quality across gestation is related to objective changes in sleep macrostructure, which become particularly evident in the third trimester. Pregnancy per se does not represent an independent risk factor for developing major polysomnography-assessed sleep disorders in otherwise healthy women. However, in women presenting predisposing factors, such as obesity or hypertension, physiological changes occurring during pregnancy may contribute to the onset of pathological conditions, especially sleep-disordered breathing, which must be carefully considered.

睡眠障碍的症状在孕妇中很常见，并且在整个妊娠期间通常会恶化。妊娠相关的睡眠障碍不仅与受影响母亲的生活质量差有关，而且与不良的围产期结局有关，包括围产期抑郁，妊娠糖尿病，先兆子痫和早产。关于怀孕期间睡眠障碍的影响的当前知识很大程度上来自对不同人群进行的睡眠调查的结果。但是，近年来，通过多导睡眠图检查检查怀孕期间客观睡眠变量变化的研究数量已逐渐增加。

在这里，我们系统地回顾了文献中提供的多导睡眠监测研究，旨在描述睡眠模式并确定孕妇睡眠中断的可能标志。

根据我们的分析，整个妊娠期间睡眠质量的主观恶化与睡眠宏观结构的客观变化有关，这一点在孕晚期尤为明显。怀孕本身并不代表在其他健康女性中发展多导睡眠图评估的主要睡眠障碍的独立危险因素。但是，在表现出肥胖或高血压等诱发因素的女性中，怀孕期间发生的生理变化可能会导致病理状况的发作，尤其是睡眠呼吸紊乱，必须仔细考虑。
