The relation between mortality of people aged 45 to 74 and atmospheric smoke and sulphur dioxide in the county and London boroughs of England and Wales was investigated using data for the years 1969 to 1973. Weighted multiple regression analyses, which took into account a number of socioeconomic and climatic variables, showed no consistent relation of smoke or sulphur dioxide with mortality from all causes or with mortality from specified causes postulated a priori to be related to pollution. In particular there was no significant association between smoke and mortality rates for respiratory illness. Comparison with results from similar analyses of data for the two previous decades suggested that a decline in the strength of associations had occurred in parallel with declining levels of the pollutants.
利用1969年至1973年的数据,对英格兰和威尔士各郡及伦敦行政区45至74岁人群的死亡率与大气中的烟雾和二氧化硫之间的关系进行了调查。加权多元回归分析考虑了一些社会经济和气候变量,结果表明,烟雾或二氧化硫与所有原因导致的死亡率,或与事先假定与污染有关的特定原因导致的死亡率之间,没有一致的关系。特别是,烟雾与呼吸道疾病死亡率之间没有显著关联。与前二十年类似数据分析结果的比较表明,随着污染物水平的下降,关联强度也出现了下降。
