Epidemiology of Stroke in Urban and Rural Areas,Tianjin,China: A Six-year Prospective Research

采用前瞻的方法，对天津市城乡各一个监测点脑卒中发病死亡的状况进行６年前瞻性研究。结果表明：城乡脑卒中发病率和死亡率无明显差别（Ｐ＞０．０５）；但均随着年龄的增加而逐渐升高。总发病密度城乡分别为４４３．８６／１０万人年和４０２．０５／１０万人年，总死亡率则分别为２４８．２０／１０万人年和１９０．２２／１０万人年。在发病类型上无明显的城乡差异；城市脑出血死亡率在４５岁以后明显高于脑梗塞死亡率，农村则是在５５岁以后出现这种趋势。还发现城乡的发病和死亡均在１０月份出现一个高峰。
