To evaluate the effect of long-term intervention on all-causes mortality and the mortality of cardiovascular diseases. In May 1987 in Beijing, 2 geographically separated community with a registered population of about 10 000 each were selected as either intervention or control community. In each community, a cohort containing 2 700 subjects (>/= 35 years) free of stroke was sampled. A baseline survey was administered to screen the eligible subjects for intervention. Death information from the cohorts was collected. By the end of Dec. 31, 1995, the 9-year cumulative all-causes mortalities were 3.51% (303/2 861) in the intervention cohort and 4.71% (390/2 760) in the control cohort. Cardiovascular diseases and neoplasm were the first and second leading causes of death in the cohorts. Both the all-causes mortality and the mortality of cardiovascular diseases were significantly lower in the intervention cohort than in the control group. The risk for dying of all-causes death was reduced by 22% (RR = 0.78, 95% CI: 0.67 approximately 0.91) and the risk for dying of cardiovascular diseases was reduced by 24% (RR = 0.76, 95% CI: 0.57 approximately 0.96) in the intervention cohort. Long-term community intervention for the risk factors of cardiovascular diseases can effectively reduce the mortality of cardiovascular diseases as well as all-causes mortality.
