摘要
对沈阳市不同污染区进行了一次慢性病患病率和多种环境因素相关的调查研究。在进行多因素分析后，看到吸烟是慢性呼吸道病的第一位病因。室内污染指数使慢性气管炎和ＣＯＰＤ分别升高１．５（１．３～２．５）及１．４（１．０～１．９）倍，室外污染在调控年龄、文化和上述诸因素后仍使慢性呼吸系统病和心脑血管病ＯＲ值升高至１．４（１．０～２．１）和１．７（１．１～２．６）。３区在急慢性发病及医疗费支出等方面均有显著差异。经多因素调控后的室外污染对ＣＯＰＤ及心脑血管病患病率的ＯＲ值与在另一研究（大气污染与死亡率生态学分析）中所得的ＲＲ值相近似，为室外污染的病因分数（ＰＡＲ）提供了依据．
A study on the relationship between air pollution and chronic diseases was conducted in Shenyang city. After multivariable analysis,cigarette smoking was found being the predominant cause for chronic respiratory diseases. Indoor air pollution index increased the ORs of chronic bronchitis and chronic obstructive pulmonary diseases (COPD) to 1. 5 (95%Cl1. 3～2. 5) and 1. 4 (1. 0～1. 9) and cerebral-heart vascular diseases by1. 4(1. 0～2. 1 )and 1. 7(1. 1～2. 6)respectively after control for age, education, smoking, and indoor air pollution. The incidence of acute or chronic diseases and medical expenses among peoples living at three areas with high,middle and low air pollution were also significantly different. The result from this study about ORs of COPD and CVD raised by air pollution are comparable with that we got from a mortality ecological study in Shenyang city. These studies provide basic for estimating the attributable risk(causal fraction)of outdoor air pollution for high level polluted cities.
