作者研究了成都市1982年～1989年环境气候因素对疾病死亡率的影响.用逐步回归分析,发现:循环系疾病、心脏病和呼吸系疾病的总死亡率及脑血管病死亡率与日照时数呈负相关;循环系疾病总死亡率、脑血管病死亡率和气温呈正相关;肺心病、支气管炎、哮喘和肺气肿的死亡率与气温呈负相关;循环系疾病、呼吸系疾病的总死亡率、脑血管疾病死亡率与降雨日呈负相关;肺炎、支气管炎、哮喘和肺气肿的死亡率与雾日呈正相关关系。
The authors studied the impact of environmental climatic factors on disease mortality in Chengdu from 1982 to 1989. By stepwise regression analysis, it was found that the overall mortality and cerebrovascular disease mortality of circulatory diseases, heart diseases and respiratory diseases were similar to those of sunshine hours There was a negative correlation between the total mortality of circulatory diseases and the mortality of cerebrovascular diseases and air temperature. The mortality of pulmonary heart disease, bronchitis, asthma and emphysema was negatively correlated with air temperature. The circulatory diseases, respiratory diseases The mortality rate of total mortality and cerebrovascular diseases was negatively correlated with the rainfall day. The mortality rates of pneumonia, bronchitis, asthma and emphysema were positively correlated with the fog days.
