[Status and trend of cardio-cerebral-vascular diseases mortality in China: data from national disease surveillance system between 2004 and 2008].

OBJECTIVE

To report the status and trend of cardio-cerebral-vascular disease (CCVD) mortality in China between 2004 and 2008.

METHODS

The mortality data from population-based survey of National Disease Surveillance System in 2004 and 2008 were analyzed. This surveillance system is consisted of 161 disease surveillance points (DSPs) located in 31 provinces of China including 64 urban and 97 rural DSPs. The total population of surveillance is over 73 millions and accounted for around 6% of the whole population of China. CCVD included ischemic heart diseases (ICD-10: I05-I09, I11, I20-I27, I30-I52) and cerebral-vascular disease (ICD-10: I60-I69). The status and trend of cardiovascular disease (CVD), cerebral-vascular disease (CD), ischemic heart disease (IHD) and acute myocardial infarction (AMI) mortalities from 2004 to 2008 were analyzed by age, gender, and urban/rural regions.

RESULTS

The mortality of CCVD was higher in 2008 (229/100 000) than in 2004 (223.5/100 000), which was decreased in urban region (-11.7/100 000) while increased in rural region (+16.0/100 000). The mortality of CD decreased from 134.8/100 000 (2004) to 128.3/100 000 (2008). Mortality of IHD and AMI increased from 66.1/100 000 and 40.4/100 000 (2004) to 71/100 000 and 45.7/100 000 (2008), which remained stable in urban region (+0.98/100 000 and -1.96/100 000) while significantly increased in rural region (+6.7/100 000 and +9.2/100 000). The mortality rates for CVD, CD and AMI were higher in rural population than that in urban population. The age-standardized mortality rates of CVD, CD and IHD were lower in 2008 than in 2004. The mortality rates of CD and IHD decreased in 40-, 60-, and over 80 age groups (except for IHD) in 2008 than in 2004. However, IHD mortality was significantly higher in age of 80 and over group from 2004 to 2008. There were a net 5.5/100 000 increase, 6.4/100 000 decrease and 4.9/100 000 increase for CCVD, CD and IHD between 2004 and 2008. The mortality rate rise in CCVD was mainly due to the increased mortality of IHD and CD in rural population. The CCVD mortality increased with age and was significantly higher in male than in female population.

CONCLUSIONS

Despite decreased mortality in CD, CCVD mortality increased from 2004 to 2008, mainly due to the increased mortality of IHD and AMI in rural population. Enhanced CCVD primary and secondary prevention, particular for stressing on primary prevention, is necessary in China, especially in rural areas. Meanwhile, they will give the greatest contributions for a raise of the healthy life expectancy in China.
