What does this research mean for the field?

Adverse sleep patterns, characterized by short duration and poor quality, are common and worsen across pregnancy, disproportionately affecting non-Hispanic Black individuals and those with lower socioeconomic status. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

To characterize longitudinal trajectories of sleep duration, quality, and midpoint across pregnancy and identify maternal factors associated with adverse sleep profiles.

Overview

Longitudinal cohort study reveals widespread declines in sleep quality and high rates of short sleep across pregnancy, highlighting the need for routine prenatal sleep screening.

Key Points

To characterize longitudinal trajectories of sleep duration, quality, and midpoint across pregnancy and identify maternal factors associated with adverse sleep profiles.
Analyzed longitudinal data from 303 pregnant individuals enrolled in the Human Placenta and Phthalates Study in Virginia and Texas across up to eight visits between 13 and 36 gestational weeks.
Evaluated repeated measures of self-reported sleep duration, quality, and midpoint using generalized estimating equations and identified multi-trajectory profiles via group-based trajectory modeling.
Over the course of pregnancy, the rate of short sleep (< 7 hours) increased and perceived sleep quality declined, while sleep midpoint remained relatively stable across racial and ethnic groups.
Non-Hispanic Black individuals were 8% more likely to report short sleep than non-Hispanic White individuals, whereas Hispanic/Latina individuals reported superior sleep quality.
Trajectory modeling identified three groups: 'Worst Sleepers' (60.7%), 'Restless Sleepers' (25.4%), and 'Best Sleepers' (13.9%), with adverse profiles enriched among non-Hispanic Black participants (64%), nulliparous individuals (53%), and those with higher BMI or government insurance.
