Abstract DP360: Association of Daily Sleep Duration with Stroke among Patients with Different Hypertension Status

Introduction: Sleep deprivation is associated with the risk of stroke. The association between sleep duration and stroke among patients with different hypertension statuses is unclear. We aim to examine the association of sleep duration on weekdays and weekends with a history of stroke in patients with and without hypertension. Methods: A cross-sectional study using the 2017-2023 NHANES included adults with and without a history of stroke. The association of tertiles (T) of sleep durations on weekdays and weekends with a history of stroke was examined by multiple binary logistic regression analyses. Results: Of 17,846 participants ≥18 years old, the mean±SD age was 51±19 years, and 53% were female. Mean sleep durations on the weekdays, weekends, and whole week were 7.68±1.66, 8.30±1.77, and 7.99±1.53 hours, respectively. Mean sleep durations on the weekdays in T1, 2, and 3 were 6.12, 7.83, and 9.44 hours, and sleep duration on the weekends were 7.01, 8.85, and 10.56 hours, respectively. There were 854 patients (5.01%) ever had a stroke. Up to 73% of patients with stroke had hypertension, while 36% of non-stroke participants were hypertensive (P
