Abstract
STUDY OBJECTIVES: Non-Hispanic Black pregnant women disproportionately experience poor perinatal outcomes compared to other racial/ethnic groups. Sleep disruption has emerged as a risk factor for adverse pregnancy outcomes but there are limited data in minority pregnant women. We examined the prevalence of habitual snoring and its timing of onset with several key sleep-wake disturbances and their associations with perinatal outcomes in a cohort of non-Hispanic Black pregnant women.
METHODS: Third trimester non-Hispanic Black pregnant women were recruited from a large, academic medical center and screened for habitual snoring - and its timing relative to pregnancy - sleep quality, symptoms of insomnia, excessive daytime sleepiness, as well as daytime function. Clinical diagnoses of hypertensive disorders of pregnancy were obtained along with delivery outcomes.
RESULTS: In 235 women the vast majority (80%) reported three or more sleep-wake disturbances, and almost half had at least five disturbances. Sixteen percent endorsed pre-pregnancy snoring and 20% pregnancy-onset snoring. Women with pregnancy-onset snoring had significantly increased odds of poor sleep quality aOR 8.2, trouble staying asleep aOR 3.6, waking up too early aOR 2.7, excessive daytime sleepiness aOR 2.3, and poor daytime function aOR 8.7 but no relationship with perinatal outcomes. In contrast, pre-pregnancy snoring was related to chronic hypertension, pre-term delivery and fetal growth restriction; aOR 2.6, aOR 2.8, and aOR 5.1 respectively.
CONCLUSIONS: Sleep-wake disturbances confer a significant burden to pregnant non-Hispanic Black women, an infrequently studied yet disproportionately affected population. Contributions of maternal sleep to racial disparities in perinatal health should be a priority for public health research.
