The Association Between Habitual Sleep Duration and Blood Pressure Control in United States (US) Adults with Hypertension

Purpose: This study examined the relationship between habitual sleep duration and blood pressure (BP) control in adults with hypertension. Methods: This cross-sectional study used data of 5163 adults with hypertension obtained from the 2015-2018 National Health and Nutrition Examination Survey (NHANES). Multivariable logistic regression was used to analyze the association between habitual sleep duration and BP control. Habitual sleep duration was self-reported and defined as the amount of sleep usually obtained in a night or main sleep period during weekdays or workdays. It was categorized as <6, 6 - <7, 7-9, and >9 hours. BP control was defined as average systolic BP <130mmHg and diastolic BP <80mmHg. Results: = 0.002). No significant differences were noted in all adults with hypertension and in the subpopulation of those on antihypertensive medication in BP control between the reference sleep duration group (7-9 hours) and the 6 - <7 or >9 hours groups. There were no significant differences across age groups or gender in the relationship between habitual sleep duration and BP control. Conclusion: Sleep duration of <6 hours is associated with reduced odds of hypertension control. These significant findings indicate that interventions to support adequate habitual sleep duration may be a promising addition to the current hypertension management guidelines.
