Abstract

With a purpose to difine risk factors of respective subtypes of cerebrovascular disease, a case-control study was performed in 1,251 cases with cerebrovascular disease who were admitted to twelve large institutions over the country during the year of 1988. All cases were subtype-proven by computerized tomography. Three hundred and eighty three patients were selected as control among the patients who were admitted to the same hospitals during the same period. The variables were collected prospectively and the data were processed by univariate and multiple logistic regression analyses and the significance was tested by chi-square methods. In the univariate analysis, female sex, being a physical worker, history of hypertension either treated or not and previous stroke history were significantly related with cerebral hemorrhage. Male sex, being aged 60 or more, living in city area, being a mental worker, history of hypertension either treated or not, history of stroke, being a diabetic and positive family history of stroke were significantly related with cerebral infarction. In multiple logistic regression analysis hypertension and alcohol drinking were strong independent risk factors for cerebral hemorrhage. Hypertension, being aged 60 or more, and living in urban area were also independent risk facrots for cerbral infarction. Of the other variables analyzed, socioeconomic class, smoking history or body mass index did not constitute significnat risks for either cerebral hemorrhage or cerebral infarction.
