摘要
本文研究北京清洁区(海淀区)低空气污染条件下居民死亡率与TSP及SO_2的关系.采用了通用估计方程(GEE)方法对泊松回归模型进行参数估计.结果表明,在控制了所有气象因素之后,居民每日死亡人数与SO_2日浓度有显著性关系(β=0.173,T=2.20).文章还给出了分年龄和死因别所作分析结果.最后的结论是:空气污染即使是在低于WHO推荐标准的情况下仍能造成居民的超死亡,这一现象对老年人及呼吸与心血管系统病人更为明显.
The present study examines the relation of air pollution; total suspended paniculate (TSP) and sulfur dioxide (SO2) with daily mortality of residents in Beijing less polluted area (Haidian district). Generalized Estimation Equation (GEE) was used to estimate parameters of poisson regression model. After controlling weather factors, a significant association between daily SO2 concentration and daily mortality was found (β=0. 173, T=2.20). The effect was stronger among patients with chronic obstructive pulmonary disease and cardiovascular disease as well as among elder people.
