Understanding the Relationship between Sleep Duration and Blood Pressure Based on Differing Neighborhood Condition Perceptions in Black Postpartum Individuals.
Master Essay, University of Pittsburgh.
Abstract
Background: Hypertension is a leading cause of maternal morbidity and mortality among Black postpartum women. Sleep is associated with hypertension risk in the general adult population, but the relationship between sleep and hypertension postpartum is less understood. Additionally, the impact of the social determinants of health, like neighborhood conditions, on this link is not well understood and studied. This study aimed 1) to investigate the correlation between sleep duration and blood pressure at 2 and 6 months postpartum in Black-identifying individuals and 2) to determine if these correlations differed by neighborhood conditions. Methods: This was a secondary data analysis of the Pittsburgh Girls Study-Health Over the Peripartum Period (PGS-HOP), a prospective cohort of Black postpartum individuals (n=180). Systolic and Diastolic blood pressure (SBP, DBP) was measured by trained study team members. Mean arterial pressure (MAP) was generated using the SBP and DBP values. The Your Neighborhood Questionnaire was used to measure neighborhood conditions. We used a median split to define low and high perceived neighborhood conditions. We used Spearman correlations to characterize the relationships between sleep and blood pressure overall and stratified by neighborhood conditions. Results: Results showed no associations between sleep duration and blood pressure or MAP at 2 and 6 months (2 months: SBP rho= 0.0032, DBP rho= 0.075, MAP rho= 0.047, all n.s.; 6 months: SBP rho=0.023, DBP rho= 0.12, MAP rho=0.093, all n.s.) . Within the neighborhood stratification, we also report null associations for 2 and 6 months for both the better and worse perceived neighborhood conditions groups (2 months: SBP rho=0.0032, DBP rho=0.075, and MAP rho=0.047, all n.s.; 6 months: SBP rho=0.023, DBP rho= 0.12, and MAP rho=0.093, all n.s.). Discussion: In this analysis, we did not observe any associations between sleep duration and blood pressure at 2 and 6 months postpartum. Future research with adequate sample sizes should examine associations between other sleep domains (e.g., sleep regularity, sleep quality) and blood pressure, an area of great public health significance.
