Abstract P154: Differences In Sleep Duration Between Black Ethnic Subgroups And Non-hispanic White Adults With Hypertension In The 2004 - 2018 National Health Interview Survey

Abstract

Background: Sleep is a naturally occurring period of lower blood pressure (BP), recommended by the AHA as an essential lifestyle feature to prevent cardiovascular disease (CVD). While hypertension (HTN) disproportionately affects Black adults in the United States (US), differences in sleep duration among Black ethnic subgroups including African American, African immigrant, and Afro-Caribbean adults with hypertension are unknown. Objective: To examine differences in sleep duration among Black ethnic subgroups and Non-Hispanic (NH) White persons with HTN in the US. Methods: Using cross-sectional data from the 2004-2018 National Health Interview Survey, sleep duration was defined by participants’ self-reported average number of hours of sleep per day. Survey-weightedgeneralized linear models were used to examine the differences between sleep duration among the Black ethnic subgroups with hypertension compared to their NH White counterparts. Results: Of 120,511 adults (17% Black, 51% female with mean age 57±.08 [SE] years) mean(±SE) sleep duration was 7.2 (0.01) hours. Unadjusted, African immigrants had the shortest mean sleep duration (6.8 hours) compared to NH White persons (7.2 hours). In the fully adjusted model, compared to NH White persons, all adults in the Black Ethnic Subgroups had significantly lower sleep durations compared to White persons, with Afro-Caribbean persons having the lowest sleep duration ( Table ). Conclusion: Sleep duration varied across ethnic subgroups of Black adults with self-reported HTN. Whether interventions targeting these differences could improve hypertension control represents an important subject for subsequent research.
