Abstract:
Objective To explore the relationship between duration of sleeping and cerebral infarction.Methods A case-control study involved 1037 cerebral infarction patients admitted by the Second Affiliated Hospital of Harbin Medical University,December 2011-December 2012 as cases.Another 1205 adults free from cerebro-vascular diseases who had undergone physical examination in the hospital at the same period,were served as controls.All the subjects were interviewed with unified questionnaire.Chi-square test,u-test and multivariate logistic regression analysis were performed.Results After adjustment for potential confounding factors including age,sex,body mass index,wrist-hip ratio,smoking,alcohol intake,hypertension,diabetes mellitus,coronary artery disease and lipid parameters,data from the multivariate logistic regression analysis showed that the risk of cerebral infarction was greater in people who slept less than 6 hours per night than those who slept between 6 hours and 8 hours per night,with an odds ratio (95％ CI) as 2.81 (95％ CI:1.68-4.70).There was no significant association between factor as ‘sleeping longer than 8 hours/pre day' and cerebral infarction.Through the subgroup analysis,data showed that the association between ‘ shorter than 6 hour sleep/night' and cerebral infarction consistently exsited,across the categories of sex,and the degree of association was greater in women than in men,with the odds ratio as 5.58 (95％CI:1.78-17.52) and 2.00(95％CI:1.10-3.64) respectively.Conclusion Short sleeping duration might increase the risk of developing cerebral infarction.
