Abstract

Objectives To evaluate the impact of cerebrovascular disease deaths on life expectancy (LE) of Chinese residents in 2010 and its change compared with 2005, and then to find the high risk population (age, gender and region) whose deaths caused by cerebrovascular disease made the main impact on the LE

Methods LE and cause-eliminated LE were calculated by standard life table techniques using the adjusted mortality data from National Disease Surveillance System: The Death Surveillance Data Sets in 2005 and 2010. Decomposition method was used to quantitatively evaluate the impact of cerebrovascular disease.

Results The LE of Chinese residents was 73.24 years in 2010, which was higher in women and urban residents compared with men and rural residents. The LE loss caused by cerebrovascular disease deaths in Chinese residents was 2.26 years, it was higher in men and rural residents compared with women and urban residents, and more than 30% of LE loss came from the premature deaths of cerebrovascular disease in people who were less than 65 years old. Compared with 2005, The LE of Chinese residents increased 0.92 years, and the change of cerebrovascular disease deaths contributed 0.04 years to the increase of LE (0.45 years for urban residents), but the increase of cerebrovascular disease deaths made 0.12-year LE loss for rural residents.

Conclusions The cerebrovascular disease deaths had a tremendous impact on LE in Chinese population, and the impact was significant different between urban residents and rural residents. LE is likely to be further increased by reducing deaths caused by cerebrovascular disease, and the special attention should be paid to reduce the premature cerebrovascular disease deaths in people who were less than 65 years old.
