There are limited studies investigating the relationship between exposure to PM and the health status among the mobile population. A cross-sectional analysis was performed in a nationally representative sample (2017 China Migrants Dynamic Survey data) consisting of 169,469 mobile population. The ordered logistic regression model was used to examine the association between PM and the health status in mobile population. Stratified analyses were performed to identify whether the association varied across gender, age group, and regions in China. Overall, every 10 μg/m increment in annual average PM was associated with increased risk of poor self-reported health (OR = 1.021, 95% CI: 1.012-1.030). Mobile population aged 31-49 years and living in the central region suffers the highest PM-associated health risk (OR = 1.030, 95% CI: 1.019-1.042; OR = 1.095, 95% CI: 1.075-1.116). Our study suggests that PM exposure was associated with an increased risk of poor self-reported health in mobile population, particularly among the population aged 31-49 years and people living in the central region of China. Policymakers should pay more attention to the vulnerable mobile population to tackle the health burden of ambient air pollution.
针对流动人口中 PM 暴露与健康状况之间的关系，目前研究有限。本研究采用横断面分析方法，对一个具有全国代表性的样本（2017 年中国流动人口动态监测调查数据）进行了分析，该样本包括 169469 名流动人口。采用有序逻辑回归模型来检验 PM 与流动人口健康状况之间的关系。进行分层分析以确定这种关联是否因性别、年龄组和中国各地区的不同而有所差异。总体而言，每年平均 PM 每增加 10μg/m，自述健康状况不佳的风险就会增加（OR=1.021，95%CI：1.012-1.030）。31-49 岁且居住在中部地区的流动人口受到的 PM 相关健康风险最高（OR=1.030，95%CI：1.019-1.042；OR=1.095，95%CI：1.075-1.116）。本研究表明，PM 暴露与流动人口自述健康状况不佳的风险增加有关，尤其是 31-49 岁的人群和居住在中国中部地区的人群。决策者应更加关注弱势流动人口，以应对环境空气污染对健康造成的负担。
