Correlation between sleep duration and ischemic stroke: A large community study

ABSTRACT

Objective To investigate the relationship between sleep duration (SD) collected by polysomnography and ischemic stroke in community populations. Methods We recruited 2062 participants, including 724 males and 1338 females. The mean age of the all participants was 61.44 years. In this study, the subjects were divided into three groups according to SD short SD (8 h), and normal SD (6-8 h). Logistic regression was used to analyze the independent association between the three different sleep durations and the occurrence of ischemic stroke. Results ① The three groups differed significantly in gender, age, BMI, prevalence of diabetes and serum triglyceride levels (P<0.05). ② The incidence of ischemic stroke was significantly higher in short SD group than in long SD group and normal SD group (the incidence rates were 5.9%, 2.7% and 1.6%, respectively; P=0.044, P<0.001). ③ Univariate logistic regression analysis suggested that short SD was associated with the occurrence of ischemic stroke (OR=3.845, 95% CI 1.789-8.266, P=0.001). After adjusting potential factors such as gender, age, marital status, alcohol consumption, hypertension, diabetes and triglycerides, multivariate logistic regression analysis showed that short SD was still an independent risk factor for ischemic stroke (OR=2.629, 95% CI 1.033-6.693, P=0.043). Conclusion The incidence of ischemic stroke differs in people with different SD. Among them, the incidence of ischemic stroke is higher in people with short SD.
