title: [An evaluation of the impact of cerebrovascular disease deaths on life expectancy in China].
abstract: OBJECTIVE
  To evaluate the impact of cerebrovascular death on the life expectancy of Chinese residents in recent years and explore the difference in the subgroups.
  
  
  METHODS
  Life expectancy and cause-elimination life expectancy were calculated by standard life table techniques using the adjusted mortality data from the Death Surveillance Data Sets in 2005 and 2010 provided by the National Disease Surveillance System. Decomposition method was used to quantitatively evaluate the impact of cerebrovascular disease.
  
  
  RESULTS
  The life expectancy of Chinese residents was 73.23 years old in 2010. The loss of life expectancy caused by cerebrovascular death was 2.26 years in 2010, with about 97% of that came from the elimination of deaths in the residents aged over 40 years old. Compared with 2005, the reduction of cerebrovascular deaths contributed to a total of 0.04 years increase in the life expectancy of Chinese residents in 2010, with 0.45 years for urban residents. However, for the rural residents, cerebrovascular death increased and caused 0.12 years decrease of life expectancy.
  
  
  CONCLUSIONS
  The impact of cerebrovascular death on the life expectancy of Chinese residents is still great. Significant difference is showed between the urban and rural areas with reduction in the urban but increase in the rural. The life expectancy is likely to be further increased by reducing cerebrovascular death in the Chinese residents aged over 40 years old.
