Abstract:
Objective To investigate the relationship between sleep duration and the risk of stroke in Asian populations.Methods Using duration of sleep,stroke and cerebrovascular event as search terms,we searched the China National Knowledge Internet (CNKI),Wanfang,Chinese BioMedical Literature(CBM),Vip Citation Databases(VIP),PubMed,EMBASE and Science Citation Index databases from the time of database construction to April 1,2018.Observational studies including cross-sectional studies,case-control studies and cohort studies that aimed to investigate the relationship between sleep duration and the risk of stroke in Asian populations were collected.Two investigators independently screened the literature,extracted data and assessed the quality of included studies.All analyses were performed by using the Stata 12.0 software.Results A total of 18 studies,including 658 778 participants,were included in this meta-analysis.Pooled results showed that short sleep duration was not associated with increased risk of stroke(OR =1.08,95 ％CI:0.96-1.22,Z =1.27,P =0.205),but long sleep duration was associated with increased risk of stroke(OR =1.61,95 ％CI:1.42-1.83,Z =7.49,P ＜ 0.001).Subgroup analysis showed that short sleep duration was correlated with a high risk of stroke only in the Singaporean population while it was not the case in other Asian populations,and long sleep duration was correlated with a high risk of stroke in many studies except in pooled results of case-control studies and pooled research results concerning the Korean population.Conclusions Long but not short sleep duration is a risk factor for the incidence of stoke in Asian populations.
