Mid‐pregnancy and postpartum maternal mental health and infant sleep in the first year of life

Sleep During Pregnancy and Offspring Outcomes From Infancy to Childhood: A Systematic Review

OBJECTIVE

Prenatal sleep problems have been previously linked to poor birth outcomes. However, much less is known about the associations between poor prenatal maternal sleep and offspring outcomes after birth. The purpose of this systematic review was to synthesize the findings linking prenatal maternal sleep health and offspring health and development during infancy and childhood.

METHODS

A total of 4650 nonduplicate articles were identified via PsycInfo and PubMed databases. After screening and full-text review, 34 articles met the inclusion criteria and were extracted for information.

RESULTS

The bulk of studies in this review (n = 19; 76.5%) were published between 2019 and 2024. Measures of prenatal sleep included sleep timing, quality, sleep disorders and/or symptoms of disorders, and daytime sleepiness. Offspring outcomes were categorized as follows: a) sleep health (e.g., nighttime sleep duration, night wakings), b) physical health (e.g., body mass index, hospitalizations), c) child developmental outcomes (e.g., global development, negative affect, executive functioning), and d) brain structure and function (e.g., brain volume, event-related potentials). Evidence consistently links poor prenatal sleep health to poorer offspring sleep, higher body mass index, higher prevalence of physical health conditions, poorer global development, and more behavioral problems. Emerging evidence also links prenatal sleep to differences in offspring brain structure and function.

CONCLUSIONS

Poor prenatal maternal sleep health may be an environmental signal that informs offspring health. Future studies are needed to fully understand the pervasive, intergenerational, and long-lasting effects of sleep across pregnancy.

Sleep quality disparities in different pregnancy trimesters in low- and middle-income countries: a systematic review and meta-analysis

INTRODUCTION

Sleep is a crucial determinant of maternal and fetal health, significantly impacting the well-being of both the mother and her developing fetus. Poor sleep quality, characterized by difficulties in falling asleep or staying asleep, can cause poor pregnancy outcome. Conversely, studies came with inconsistent result in the prevalence of poor sleep quality in different trimester of pregnancy. Therefore, this systematic review and meta-analysis study aimed to compare the prevalence of poor sleep quality in different trimesters.

METHOD

A systematic review and meta-analysis were done on published studies. Electronic data base search was done from PubMed, Hinari, Medline and Google Scholar. Data were extracted with Excel and the analysis were done using STATA version 17. Publication bias was assessed both graphically and statistically. I-square test was used to identify heterogeneity.

RESULT

In this meta-analysis, 38 studies that measured poor sleep quality using the Pittsburg Sleep Quality Index (PSQI ≥ 5) were included. The pooled prevalence of poor sleep quality was identified as 37.46% (95% CI: 29.26, 45.67) in the first trimester, 47.62% (95% CI: 42.23, 53.02) in the second trimester, and 60.05% (95% CI: 51.32, 68.78) in the third trimester.

CONCLUSION

This study identified a significant discrepancy in the prevalence of poor sleep quality, which increases as gestational age advances. Therefore, this discrepancy should be addressed, and additional support should be provided to pregnant women to help them achieve adequate sleep, especially as gestational age advances.

Correlation Between Maternal Anxiety During Mid-Pregnancy and Subsequent Infant Sleep Issues: A Cross-Sectional Study from 2015 to 2016

Purpose

To explore the correlation between maternal anxiety during mid-pregnancy and infant sleep issues based on the anxiety status of mothers in mid-pregnancy.

Patients and Methods

A cohort of 2122 primigravida women from Ma'anshan City, Anhui Province, was followed from pregnancy until 6 months postpartum. The study analyzed the impact of maternal anxiety on infant sleep patterns, including primary caregivers, encompassing insufficient sleep duration, frequent nocturnal awakenings, prolonged nocturnal awakening durations, and elongated sleep latency.

Results

A total of 1891 mother-infant pairs were included in this analysis. After adjusting for confounding factors, a positive correlation was found between maternal anxiety during mid-pregnancy and insufficient sleep duration (OR=1.69, 95% CI:1.13-2.52), and elongated sleep latency (OR=2.26, 95% CI:1.61-3.18).

Conclusion

Maternal anxiety during mid-pregnancy is associated with sleep issues in infants. Addressing maternal mental health during pregnancy may enhance sleep quality for mothers and infants, promoting overall maternal-infant health.
