The analysis of the epidemiological investigation of the death data of two natural population communities in Yinchuan City showed that the deaths of 132 patients with various diseases in the stroke risk factor intervention group from 1986 to 1989 had a total mortality rate of 505 per 100,000. The ratio between men and women is 1.7:1. There were 173 deaths due to various diseases in the control group, with a total death rate of 611 per 100,000 and a ratio of 1.5:1 between men and women. The mortality rate (adjustment) of the intervention group decreased by 22.6% in 1989 compared with 1986, and the control group increased by 47.49% in 1989 compared with the 1986 mortality rate (adjustment). The cause of death was significant in both groups, and cerebrovascular disease. The intervention group retired from the 3rd place to the 5th place from 1986 to 1989, and the control group rose from the 5th place to the 3rd place, showing the effect of the intervention.
