This study examines traffic-related air pollution in London in relation to area- and individual-level socio-economic position (SEP). Mean air pollution concentrations were generally higher in postcodes of low SEP as classified by small-area markers of deprivation (Index of Multiple Deprivation (IMD) domains) and by the postcode-level ACORN geodemographic marker. There were exceptions, however, including reversed directions of associations in central London and for SEP markers relating to education. ACORN predicted air pollution independently of IMD and explained additional variation at the postcode level, indicating the potential value of using both markers in air pollution epidemiology studies. By contrast, after including IMD and ACORN there remained little relationship between air pollution and individual-level SEP or smoking, suggesting limited residual socio-economic confounding in epidemiological studies with comprehensive area-level adjustment.
本研究考察了伦敦与地区和个人社会经济地位（SEP）相关的交通相关空气污染。根据贫困程度的小区域标记（多维度贫困指数（IMD）领域）和邮政编码级别的 ACORN 地理人口统计学标记对 SEP 进行分类，空气污染浓度的平均值通常在社会经济地位较低的邮政编码中较高。然而，也有例外情况，包括在伦敦市中心和与教育相关的 SEP 标记的方向相反。ACORN 预测空气污染独立于 IMD，并在邮政编码级别上解释了额外的变化，表明在空气污染流行病学研究中使用这两种标记的潜在价值。相比之下，在包括 IMD 和 ACORN 之后，空气污染与个人社会经济地位或吸烟之间几乎没有关系，这表明在具有全面区域水平调整的流行病学研究中，社会经济混杂的剩余量有限。
