Sleep problems during pregnancy are prevalent and could be linked to negative outcomes during pregnancy or post-partum. However, these complaints are often underdiagnosed and undertreated. This review aimed to systematically assess the effectiveness of different interventions to ameliorate poor sleep quality and insomnia during pregnancy.

Pubmed, PsycINFO and Medline databases were systematically searched without publication period restriction until 3rd May 2019. Eligible studies had to: include pregnant women of any age and gestational age; use clinical intervention designs targeted at improving sleep outcome; report pre- and post-treatment data for one or more sleep-related outcomes; be published in English, Italian, German, Spanish, or French.

Sixteen studies were selected including 1252 expecting mothers. Studies evaluated the efficacy of various interventions: cognitive behavioral interventions for insomnia (4); pharmacotherapy (1); acupuncture (1); mindfulness and yoga (3); relaxation (5) and herbal medication (2). Only six were randomized controlled trials, and only four evaluated longitudinal outcomes. Preliminary support was found for all interventions, but our knowledge is still too limited by lack of evidence.

There is an utmost urgency to perform high-quality randomized controlled trials for insomnia interventions during pregnancy and to implement effective programs in standard gynecological care.

怀孕期间的睡眠问题很普遍，可能与怀孕期间或产后的不良后果有关。但是，这些抱怨常常得不到充分的诊断和治疗。这篇综述旨在系统地评估不同干预措施改善妊娠期不良睡眠质量和失眠的有效性。

系统搜索了Pubmed，PsycINFO和Medline数据库，且没有发布时间限制，直到2019年5月3日。使用旨在改善睡眠结果的临床干预设计；报告一种或多种与睡眠有关的结局的治疗前和治疗后数据；以英语，意大利语，德语，西班牙语或法语出版。

选择了16项研究，包括1252名准妈妈。研究评估了各种干预的功效：失眠的认知行为干预（4）；失眠的认知行为干预（4）。药物疗法（1）; 针灸（1）; 正念和瑜伽（3）; 放松（5）和草药（2）。只有六项是随机对照试验，只有四项评估了纵向结果。已为所有干预措施提供了初步支持，但由于缺乏证据，我们的知识仍然太有限。

迫切需要对孕妇失眠症进行高质量的随机对照试验，并在标准的妇科护理中实施有效的计划。
