我国七城市脑卒中危险因素干预、对照人群全死因分析

AN ANALYSIS OF DEATHS FROM ALL CAOSES BETWEEN POPULATINS OF CONTROL AND INTERVENTION OF STROKE RISK FACTORS IN CHINESE SEVEN CITIES

本文报告分析我国七城市脑卒中危险因素干预、对照人群全死因分析情况.四年共监测人群467057人年,年平均总死亡率为6.05‰,干预组死亡率5.69‰,对照组死亡率6.41‰.同时经过干预试验,七城市合计干预组死亡率较对照组明显降低(P<0.051).干预组中脑卒中(七城市)从1986～1989年死亡率显示逐年下降趋势,而对照组则不然.从年龄别构成比来看,对照组前5位疾病除意外伤亡外,各种疾病均以65～75岁死亡构成比较高,而干预组则不然.

The causes of death in 7 cities were reported. To study the risk factors of stroke, a group of intervention population was monitored and compared with the control. In total,467057 persons were monitored during the period of 1986 to 1989. The average total mortalityrate in the whole population monitored was 6. 05‰, while the rate sin intervention and control groups were 5. 69‰ and 6. 41‰respectively. The mortality rate from stroke was significantly reduced and declined step by step from 1986 to 1989 in intervention group of seven cities,but not in the control group. With the exception of accidents,the age-specific propo-tional mortality rates from the first five diseases were higher in the control group at the age of 65 to 75 years.
