Objective: Racial and socioeconomic disparities in adverse health outcomes across the lifespan are more pronounced in populations within the United States despite public health efforts to eliminate them. Black women are disproportionately affected with an increased risk for adverse perinatal outcomes. Poor sleep has emerged as a key variable linked to perinatal health. There are a lack of data on how social determinants of health impact sleep in Black pregnant women. The goal of this study was to examine whether key social determinants of health play a role in sleep.

Study Design: Third trimester Black pregnant women were recruited into a cohort study at a large tertiary medical center. All women were screened for sleep complaints including poor sleep quality, poor daytime function, excessive daytime sleepiness (EDS), sleep duration, and habitual snoring. Short sleep duration was defined as 6 or fewer hours of sleep and long sleep duration was defined as at least 10 hours of sleep. The following were considered stressors: single women, receipt of Medicaid, no more than a high school education, and age less than 21 years.

Results: A total of 289 Black women were recruited. Mean age was 27.4 +/- 6.2 years, BMI was 35.0 +/- 8.9kg/m2 and gestational age was 33.2 +/- 4.7 weeks. Overall 65% of women were single, 66% received Medicaid, 40% had no more than a high school education, and 15% were less than 21 years of age. Table 1 shows the sleep complaints by the stress indicators. Only 75 women (26%) had none of the identified stressors. Regardless of the presence and number of the stressors, EDS was present in approximately half of women, poor sleep quality and poor daytime function were present in the majority of women. Women without stressors were more likely to report short sleep than those with stressors (see Table 2) while long sleep was more common those with stressors.

Conclusion: Regardless of which social determinant was present, a large proportion of women reported poor sleep. Of note, majority of women who endorsed all four stressors reported long sleep duration, which is known to be a marker of depression.
