title: [Surveillance of incidence of cerebral hemorrhage in community populations in Changsha].
abstract: OBJECTIVE
  To observe the incidence of cerebral apoplexy among the community populations in Changsha, Hunan Province.
  
  
  METHODS
  Surveillance of the incidence of cerebral apoplexy and analysis of its subtypes were conducted among 10,000 urban residents in Changsha selected by random cluster sampling from 1986 to 1990. The number of people under surveillance was amplified to 50,000 in 1991 and the studies lasted to December 2000.
  
  
  RESULTS
  Among the Chamgsha populations, the annual average incidence of cerebral hemorrhage was 171.7 per 100,000 during the period 1986 - 1990. The annual average incidence of cerebral apoplexy was 238.9/100,000 with an adjusted rate of 200.2/100,000, and the annual average incidence of cerebral hemorrhage, accounting for 53.8% of cerebral apoplexy, was 128.5/100,000 with an adjusted rate of 100.3/100,000).
  
  
  CONCLUSIONS
  The annual average incidence of cerebral hemorrhage in community populations is 128.5 per 100,000 during the period of fifteen years, 1986 - 2000, in Changsha, one of the areas with high incidence of cerebral hemorrhage.
