Insomnia symptoms affect 38.2% of pregnant individuals, with prevalence increasing significantly in the third trimester. This review summarizes data on pregnancy insomnia and its moderators.
Area of Science:
- Obstetrics and Gynecology
- Sleep Medicine
- Perinatal Mental Health
Background:
- Sleep disturbances are frequently reported during pregnancy.
- Estimates of insomnia symptom prevalence during pregnancy vary widely in existing literature.
Purpose of the Study:
- To systematically review and summarize the prevalence of insomnia symptoms during pregnancy.
- To investigate potential moderators of insomnia symptoms, including trimester, gestational age, maternal age, anxiety, and depression symptoms.
Main Methods:
- A systematic literature search was conducted across PubMed, PsycInfo, and Web of Science databases.
- Data from 24 studies, encompassing 15,564 participants, were included in the meta-analysis.
- Prevalence rates and moderator effects were statistically analyzed.
Main Results:
- The overall prevalence of insomnia symptoms during pregnancy was found to be 38.2%.
- The third trimester showed a significantly higher prevalence (39.7%) compared to the first (25.3%) and second (27.2%) trimesters.
- Maternal age, gestational age, anxiety, and depression symptoms did not significantly moderate prevalence.
Conclusions:
- Insomnia symptoms are prevalent during pregnancy, with a notable increase in the third trimester.
- Further research is warranted to evaluate the efficacy and safety of insomnia treatments for pregnant individuals.
