采用回顾性现况调查的方法,在全国范围内(台湾省未查)抽样调查了中国1986年12月31日完全性脑中风的时点患病率,调查当日样本人口数为5 814 851人,发现脑中风病例14 275例,患病率为245.49/10万,其95％置信区间为241.57～249.61/10万,用1986年中国城乡人口构成调整后为247.66/10万,用中国1982年人口标化后为191.92/10万,用世界人口标化后为259.86/10万。 分析发现,我国脑中风的患病率从南向北越来越高,从东向西越来越低。对经、纬度和脑中风患病率之间的关系,分别配合了线性回归模型,结果为:经度,Y=12.3819x-1107.381,tb=4.649,df=5,P=0.0056;纬度,Y=12.6279x-146.6266,tb=11.7517,df=4,P=0.0003。中国脑中风的患病率在不同地形地区差别显著;城市明显高于农村,男性显著高于女性。患病率随年龄的增长而上升,它们之间的关系可用Logistic曲线模拟。
A retrospective survey was conducted to investigate the prevalence of complete stroke at 31 December 1986 in a national sample (unverified in Taiwan). The sample population on the survey day was 5 814 851 , And found 14,275 stroke cases with a prevalence of 245.49 / 100 000 with a 95% confidence interval of 241.57-249.61 / 100,000. After adjusting for the urban-rural population in China in 1986, it was 247.66 / 100,000, with a year of 1982 in China After the demobilization, 191.92 / 100,000 were standardized and 259.86 / 100,000 after the world population was standardized. Analysis found that the prevalence of stroke in our country higher and higher from south to north, getting lower and lower from east to west. The relationship between latitude and longitude and the prevalence of stroke was fitted with a linear regression model. The results were as follows: longitude, Y = 12.3819x-1107.381, tb = 4.649, df = 5, P = 0.0056; 12.6279x-146.6266, tb = 11.7517, df = 4, P = 0.0003. The prevalence of stroke in China is significantly different in different terrain areas; the city is significantly higher than the rural areas, men were significantly higher than women. The prevalence increased with age, the relationship between them can be simulated using Logistic curve.
