Abstract 55: Racial/Ethnic Disparities in Sleep Outcomes Among Adults With Hypertension in the 2011-2018 National Health and Nutrition Examination Survey

Introduction: Ethnic/racial minority groups in the US bear a disproportionate burden of hypertension (HTN). Given the association between poor sleep outcomes and HTN, we examined racial disparities differences in sleep outcomes among persons adults living with HTN in the US. Methods: We analyzed cross-sectional data from the National Health and Nutrition Examination Survey (2011-2018) . Sleep outcome variables were examined via self-report questionnaires as daytime sleepiness (no/mild/and excessive), sleep duration (recommended 7-9 hours/short ≤6 hours/and long >9 hours), sleep quality (good/ or poor). Multinomial logistic regression models were used to assess the association between race/ethnicity categories (Non-Hispanic White Americans [NHW], Non-Hispanic Black Americans [NHB], Non-Hispanic Asian Americans [NHA], and Mexicans/Hispanic Americans) and sleep outcomes, adjusting for covariates. Results: In a sample of 10,934 adults diagnosed with HTN (with mean age 58 (±16) years; and 48% female); prevalence of short sleep duration (≤ 6 hours) among NHW, NHB, NHA, and Mexicans/Hispanic Americans were 55%, 21%, 5%, and 14%, respectively. While the odds of abnormal daytime sleepiness (mild and excessive) were lower across all race/ethnic categories compared to NHW; the odds of short sleep duration were higher among NHB (adjusted odds ratio [aOR]:= 2.02; 95% confidence interval [CI]: 1.53-2.65). Similarly, the odds of poor sleep quality were higher among NHA (aOR: 1.90; 95% CI: 1.24-2.91) and Mexicans/Hispanic Americans (aOR: 1.66; 95% CI: 1.21-2.28). Conclusion: Significant racial disparities exist in sleep outcomes among adults with HTN in the US. Efforts to improve equity in HTN and CVD prevention and management must also address sleep outcomes.
