Socioeconomic status (SES) is in many cases related to air pollution exposure, but less is known about its effects on susceptibility to air pollution. The main aim of this study was to analyse the impact of SES on health effects associated with exposure to fine particles (PM).
Firstly, a systematic literature review of studies analysing the impacts of SES on health effects related to air pollution exposure was carried out. Secondly, a meta-analysis was performed by analysing studies on long-term mortality associated with exposure to PM divided into different SES groups.
The meta-analysis showed that the relative risk (RR) for all-cause mortality associated with PM did not depend on individual education or income. It also revealed that adjustment for individual lifestyle factors (such as smoking, alcohol intake, physical activity, eating behaviours, and body mass index), in addition to adjustment for SES, did not significantly change the RR.
The association between all-cause mortality and PM did not depend on education or individual income. Due to the high heterogeneity observed, further studies are required to draw firm conclusions.
在许多情况下,社会经济地位(SES)与空气污染暴露相关,但关于其对空气污染易感性的影响却知之甚少。本研究的主要目的是分析SES对与细颗粒物(PM)暴露相关的健康影响的作用。
首先,对分析SES对与空气污染暴露相关的健康影响的研究进行了系统的文献综述。其次,通过分析不同SES组中与PM暴露相关的长期死亡率的研究进行了荟萃分析。
荟萃分析表明,与PM相关的全因死亡率的相对风险(RR)并不取决于个人教育程度或收入。研究还表明,除了对SES进行调整外,对个体生活方式因素(如吸烟、饮酒、体育活动、饮食行为和体重指数)进行调整,并不会显著改变RR。
全因死亡率与PM之间的关联并不取决于教育程度或个人收入。由于观察到高度的异质性,需要进一步研究才能得出确切结论。
