This study was designed to investigate the relationship between daytime napping and stroke within a community-based cohort. METHODS The present prospective study was based on the Sleep Heart Health Study. Napping habits were assessed with a self-reported Sleep Habits Questionnaire. Participants with napping habits of different durations and frequencies were followed up until the first stroke occurred or by the final censoring date. Cox proportional hazards models was used to estimate the relationship between napping habits and stroke. RESULTS A total of 4,757 participants (2,219 men, mean age 63.6 ± 11.1 years), were enrolled in this study. Compared with those taking no naps, multivariate proportional hazards models analysis indicated that individuals taking naps with a duration of >60 min [hazard ratio (HR), 2.460; 95% confidence interval (CI), 1.538-3.934] had a higher risk of stroke. And there was also an increased risk of stroke among participants taking naps daily (HR, 1.563; 95% CI, 1.059-2.307) or 5-6 times per week (HR, 1.548; 95% CI, 1.026-2.335). After combining napping durations and frequencies, regular long naps (HR, 1.903; 95% CI, 1.182-3.065) and regular short naps (HR, 1.451; 95% CI, 1.010-2.084) were independent risk factors for incident stroke. CONCLUSIONS Daytime napping with a long duration (>30 min) or a high frequency (≥5 times per week) may increase the risk of stroke. This article is protected by copyright.

Although the biosynthetic pathways of waxes have been extensively characterized, the regulatory mechanisms underlying wax biosynthesis in tomato remain largely u
