: The impact of air pollution on residents' happiness remains unclear and the underlying mechanism remains unknown. We aimed to examine the direct effect of air pollution on residents' happiness and indirect effect through mediating their health. Based on the 2017 China Comprehensive Social Survey Data (CGSS), data on happiness were retrieved from 11,997 residents in 28 provinces in China. An ordered-probit model was used to examine the effect of air pollution on residents' happiness and health, respectively. A stepwise regression was used to derive the direct effect of air pollution on residents' happiness and indirect effect from health impairment attributable to air pollution. Air pollution was associated with lower levels of health (coef. -0.190, 95% CI -0.212, -0.167, < 0.001), while health was positively associated with happiness (coef. 0.215, 95% CI 0.196, 0.234, < 0.001). Mediation analysis methods showed that air pollution impacted residents' happiness directly and indirectly: the percent of total effect that was mediated through health was 36.97%, and the ratio of indirect to direct effect was 0.5864. Health plays a major mediating role in the relation between air pollution and residents' happiness. In order to alleviate the impact of air pollution on residents' happiness, future strategies should focus on health promotion besides reducing air pollutant emission.
空气污染对居民幸福感的影响仍不清楚，其潜在机制尚不清楚。我们旨在检验空气污染对居民幸福感的直接影响，以及通过中介健康的间接影响。基于 2017 年中国综合社会调查数据（CGSS），从中国 28 个省份的 11997 名居民中检索到幸福感数据。采用有序概率模型分别检验空气污染对居民幸福感和健康的影响。采用逐步回归法推导出空气污染对居民幸福感的直接影响和由空气污染导致的健康损害引起的间接影响。空气污染与较低的健康水平相关（系数-0.190，95%置信区间-0.212，-0.167，<0.001），而健康与幸福感呈正相关（系数 0.215，95%置信区间 0.196，0.234，<0.001）。中介分析方法表明，空气污染直接和间接影响居民的幸福感：通过健康中介的总效应的百分比为 36.97%，间接效应与直接效应的比值为 0.5864。健康在空气污染与居民幸福感之间的关系中起着主要的中介作用。为了减轻空气污染对居民幸福感的影响，未来的策略除了减少空气污染物排放外，还应注重促进健康。
