Key take away

In pregnant women, cognitive behavioral therapy effectively improves sleep quality, insomnia severity, anxiety, and depression.

Background

To determine the effectiveness of cognitive behavioral therapy for insomnia (CBT-I) or sleep disruption in pregnant women, a systematic review and meta-analysis was conducted.

Method

For a relevant literature search, databases such as VIP Database for Chinese Science and Technology Journal, Wanfang Data, Chinese National Knowledge Infrastructure, Embase, Cochrane Library, Web of Science, and PubMed were all explored. Randomized controlled studies of CBT-I in pregnant females with sleep disturbances or insomnia were included. Utilizing the Cochrane risk of bias tool, the included study's methodological bias was evaluated. RevMan 5.4 software was employed to carry out the meta-analysis. Both publication bias and the sensitivity analysis were done with the aid of Stata Statistical Software: Release 15.

Result

Overall, 8 randomized controlled studies with 743 pregnant women were incorporated. CBT-I substantially reduced depression ([standardized mean difference] SMD = -0.40), anxiety (SMD = -0.99), sleep onset latency (SMD = -1.25), Pittsburgh Sleep Quality Index (mean difference [MD] = -3.30), and Insomnia Severity Index (MD = -4.25) when contrasted to the control group. Total sleep time (SMD = 0.31) and sleep efficiency (SMD = 0.80) did not differ significantly from one another. Insomnia severity, depression, anxiety, and quality of sleep in pregnant women were all considerably enhanced by CBT-I.
