Self-reported Sleep Duration in Relation to Incident Stroke Symptoms: Nuances by Body Mass and Race from the REGARDS Study

Background: To determine, among employed persons with low risk for obstructive sleep apnea (OSA), if sleep duration is associated with incident stroke symptoms, independent of body mass index (BMI), and if sleep duration mediates racial differences in stroke symptoms.Methods: In 2008, 5666 employed participants (US blacks and whites, ≥45 years) from the longitudinal and nationally representative Reasons for Geographic And Racial Differences in Stroke study self-reported their average sleep duration. Participants had no history of stroke, transient ischemic attack, or stroke symptoms and were at low risk for OSA. After the sleep assessment, self-reported stroke symptoms were collected at 6-month intervals, up to 3 years (M = 751 days). Interval-censored, parametric survival models were conducted to estimate hazard ratios predicting time from sleep duration measurement (
