| 中文摘要: |
| 在全国范围内(台湾省未查)抽取199个调查点,共查5 790 864人,发现当年死于脑中风者4 446例,粗死亡率为76.78/10万,其95%置信区间为74.52~79.04/10万;用中国1986年农村和城市人口构成调整后,死亡率为77.15/10万;用中国1982年人口构成比标化后为57.25/10万;用世界标准人口标化后为80.94/10万。分别计算了各大区和省的脑中风死亡率,并且对脑中风标化死亡率和经、纬度的关系作了相关回归分析,发现均呈正相关,并有线性回归关系。也就是说,在中国,脑中风的死亡率从南向北逐渐升高,从东向西逐步降低。脑中风死亡率城市明显高于农村,大城市的市区明显高于其郊区。用趋势检验法和圆型分布法分析了死亡病例的按月分布,发现在一月份有一个不十分明显的,但在统计学上有意义的死亡高峰。脑中风的死亡率随年龄的增长而升高,两者之间的关系符合Logistic曲线的轨迹。 |

| This paper reported the stroke mortality rates in China in 1986.5 790 864 people from 199 locations sampling from all parts of China (the Taiwan province uninvestigated) were inverstigated and 4 446 cases of death were found.The mortality rate was 76.78 per 105 people and its 95%CI was 74.42~79.04/105.The mortality rate adjusted using population composition of the cities and rural areas of China in 1986 was 77.15/105. The mortality rate standardized by direct method use in the China population in 1982 was 57.25/105 and the mortality rate standardized use in the world standard population was 80.94/105. The mortality rates of the great regions and provinces were counted respectively, and the relationship between the mortality rates and the geographical locations were analyzed in the correlation and the regression.It was found that there were a relationships of positive correlation and liner regression between the mortality rates and the latitude degree and the longitude, that was to say, the mortality rates increased gradualy from south to noith and decreased progressively from east to weast in China. The stroke mortality rates in the cities were higher than in the rural areas, and in the city districts higher than in its outskirts in the big cities. Then the distribution of case number in monthes was analyzed using the methods of the test for trend and circular distribution, a peak of that was significantly in the statistics was found in Januaryal though it was not very high. The stroke mortality rates were gradualy arised as age increasing, and the relationship between the mortality rates and age may be fitted with the logistic curve. |
