Abstract
Sleep habits are associated with stroke in western populations, but this relation has been rarely investigated in China. Moreover, the differences among stroke subtypes remain unclear. This study aimed to explore the associations of total stroke, including ischemic and hemorrhagic type, with sleep habits of a population in southern China. We performed a case-control study in patients admitted to the hospital with first stroke and community control subjects. A total of 333 patients (n = 223, 67.0%, with ischemic stroke; n = 110, 23.0%, with hemorrhagic stroke) and 547 controls were enrolled in the study. Participants completed a structured questionnaire to identify sleep habits and other stroke risk factors. Least absolute shrinkage and selection operator (Lasso) and multiple logistic regression were performed to identify risk factors of disease. Incidence of stroke, and its subtypes, was significantly associated with snorting/gasping, snoring, sleep duration, and daytime napping. Snorting/gasping was identified as an important risk factor in the Lasso logistic regression model (Lasso’ β = 0.84), and the result was proven to be robust. This study showed the association between stroke and sleep habits in the southern Chinese population and might help in better detecting important sleep-related factors for stroke risk.
Highlights

The number of subjects reported to have a history of atrial fibrillation or flutter, rheumatic valvular heart disease and prosthetic heart valve in our study was 2 (
This study provided essential information on the association between stroke and risk factors especially concerning the sleep habits of the population in southern China
Summary
Sleep habits are associated with stroke in western populations, but this relation has been rarely investigated in China. This study aimed to explore the associations of total stroke, including ischemic and hemorrhagic type, with sleep habits of a population in southern China. Its subtypes, was significantly associated with snorting/gasping, snoring, sleep duration, and daytime napping. This study showed the association between stroke and sleep habits in the southern Chinese population and might help in better detecting important sleep-related factors for stroke risk. Various studies have examined the association between sleep duration and risk of stroke, but the results are inconsistent and dependent on social, cultural, and demographic factors[3,4,5]. Snoring is common in patents without OSA14, related researches that attended to explore the associations between stroke events and new OSA-related www.nature.com/scientificreports/
