title: [Epidemiological survey of cerebrovascular disease among population in Inner Mongolia autonomous region].
abstract: OBJECTIVE
  To understand the epidemiological characteristics of cerebrovascular disease among population in Inner Mongolia.
  
  
  METHODS
  From September 2013 to January 2014, a total of 19 315 local residents in all age groups were selected through cluster random sampling, and face to face questionnaire survey was conducted among them, than health examination was provided for them.
  
  
  RESULTS
  The overall prevalence of cerebrovascular diseases among the population in all age group was 1 812.06/100 000 (2 008.86/100 000 in males and 1 613.24/100 000 in females). The prevalence of cerebrovascular diseases increased with age, and the prevalence was higher in males than in females, in rural population than in urban population and in people with lower educational level than in people with higher educational level. The annual incidence stroke was 392.54/100 000, the difference in the incidence between males and females had no statistical significance (χ(2)=0.380, P=0.846). The incidence of stroke was higher in rural population than in urban population, the difference was statistically significant (χ(2)=13.029, P=0.000). The incidence of stroke increased with age (χ(2)=410.130, P=0.000). The annual mortality of stroke was 149.67/100 000 and the case fatality rate was 15.14%. Compared with the elderly, the prevalence of cerebral hemorrhage and cerebral infarction were higher in young people.
  
  
  CONCLUSIONS
  The prevalence, incidence, mortality and recurrence rate of cerebrovascular disease were high in the population in Inner Mongolia, ischemic stroke was the major form of cerebrovascular disease.
