摘要
本次流调共查样本246812例,其中625例完全性脑卒中病人截止调查时点仍存活。其年龄调整率为3.9/1000(按1960年美国人口构成)。本次调查在地理分布上看年龄调整率最高者为东北黑龙江省尚志县,近8.7/1000;最低者是广西南宁郊区壮族届民,为0.9/1000。患病率超过5/1000者均住于中国北部,而低于2.5/1000者均位于中国南部。若以黄河、长江为界,22个调查点可分为北、中、南三部分,由南而北呈现明显的阶梯分布。这一阶梯分布的特点与以前发表的六城市调查相似。
A door-to-door survey of neurological disorders was carried out in rural and minority areas of China in 1985. Among a sample of 246812 subjects from 21 provinces, 625 individuals alive on prevalence day were identified as having completed stroke, yielding a life-time age-adjusted prevalence ratio of 3.9/1,000 (to the 1960 U.S. population), Geographic differences were found from the survey significantly, the highest point prevalence ratio was documented in Shangzhi County of Heilongjiang province (8.7/1,000), while the lowest was reported from Nanning in Guangxi Autonomous Region (0.9/1,000). Most of places with more than 5/1,000 of prevalanec are in the northern part of China, whereas all those with lower than 2.5/1,000 are in southern China. comparing the age-adjusted prevalence of stroke for each of three parts divided by Yellow River and Yangtze River, a clear south- to- north gradient was revealed by geography. The pattern of this geographic graddient is similar to that of urban population in six cities which has been reported previously.
