Epidemiology of cerebrovascular disease mortality in China, 2006-2010

Objective To describe the epidemiologic characteristics of cerebrovascular disease (CVD) mortality in China from 2006 to 2010, understand the current status and trend of CVD mortality. Methods The mortality data and demographic data were from national death cause surveillance data set from 2006 to 2010 collected through national disease surveillance system (161 monitoring stations), which covering 6% of the total population in 31 provinces (autonomous regions, municipalities) in the mainland of China. The total population under surveillance was 365 204 390 person years during 2006-2010. According to the data sets, the CVD mortality rate, the standardized CVD mortality rate, the proportion in all death causes, the years of potential life lost (YPLL) and the standard YPLL of CVD were calculated. Results The CVD mortality rate was 124.01/lakh during 2006-2010, the standardized CVD mortality rate was 102.61/lakh, the proportion in all death causes was 21.95%, the YPLL was 449.85 person years/lakh and the SYPLL was 386.37 person years/lakh. The CVD mortality rate was 111.82/lakh in urban area and 13061/lakh in rural area, 136.71/lakh in males and 110.78/lakh in females. The CVD mortality rate, the standardized CVD mortality rate and the proportion in all death causes during this period were all in increase. The CVD mortality rate was 128.48/lakh in eastern China, 137.27/lakh in central China and 100.95/lakh in western China. The CVD mortality rate was at low level and in slow rise in east region, at high level but in slow rise in central region and at low level but in rapid rise in west region. Conclusion CVD's threat on the health and wellbeing of Chinese is on rise, which is obvious in males than in females, in rural area than in urban area. CVD's impact is most serious in central region and in rapid increase in western region.
