目的　分析缺血性和出血性脑卒中的发病率与年龄的关系。方法　对上海市静安区约 10万人群的社区进行连续 3年的心脑血管病监测 ,进行统计分析。结果　发现在 8个年龄段中有 7个年龄段两者的发病率差别有显著性 (P <0 .0 1)。两类脑卒中的发病率与年龄的指数曲线与直线回归均有一定代表性 ,相关关系呈正相关 ,相关系数r及相关指数R2 均在 0 .9以上。依据方程可对 40岁以上不同年龄人群的发病率即不同年龄者患两类脑卒中的危险性作出预测。结论　 40岁以后 ,年龄每增长 5岁 ,缺血性脑卒中发病率平均增加一倍 ,出血性脑卒中平均增加 5 0 % ,缺血性脑卒中发病率随年龄增长速度约为出血性的两倍。 Objective To analyze the relationship between the incidence of ischemic and hemorrhagic stroke and age. Methods The community of about 100,000 in Shanghai’s Jing’an District was monitored for cardiovascular disease for 3 years in a row and statistically analyzed. The results showed that there were significant differences in the incidence rates of seven of the eight age groups (P <0.01). The incidence and age of two types of stroke index curve and linear regression are some representative, the correlation was positively correlated, the correlation coefficient r and correlation index R2 were above 0.9. Based on the equation, the risk of two types of stroke at different ages over 40 years can be predicted. Conclusions After 40 years of age, the incidence of ischemic stroke doubled on average every 5 years of age. The average increase of hemorrhagic stroke was 50%. The incidence of ischemic stroke increased with age about 2 Times
