Abstract

We evaluated the long-term effects of air pollution controls on health and health inequity among Chinese >45 years of age.Data were derived from the China Health Aging and Retirement Longitudinal Survey and the China National Environmental Monitoring Centre. Decreases in PM2.5 and PM10 were scaled to measure air quality controls. We used a quasi-experimental design to estimate the impact of air quality controls on self-reported health and health inequity. Health disparities were estimated using the concentration index and the horizontal index.Air pollution controls significantly improved self-reported health by 20% (OR 1.20, 95% CI, 1.02–1.42). The poorest group had a 40% (OR 1.41, 95% CI, 0.96–2.08) higher probability of having excellent self-reported health after air pollution controls. A pro-rich health inequity was observed, and the horizontal index decreased after air pollution controls.Air pollution controls have a long-term positive effect on health and health equity. The poorest population are the main beneficiaries of air pollution controls, which suggests policymakers should make efforts to reduce health inequity in air pollution controls.

空气污染控制对中国中老年人健康和健康不平等的影响：来自面板数据的证据

我们评估了空气污染控制对 45 岁以上中国人的健康和健康不平等的长期影响。数据来自中国健康老龄化与退休纵向调查和中国国家环境监测中心。PM2.5和PM10的降幅按比例计算，以衡量空气质量控制情况。我们采用准实验设计来估算空气质量控制对自我健康报告和健康不平等的影响。使用浓度指数和水平指数估算了健康差异。空气污染控制可将自我报告的健康状况显著改善 20%（OR 1.20，95% CI，1.02-1.42）。空气污染控制后，最贫困群体自我报告健康状况优良的概率提高了 40%（OR 1.41，95% CI，0.96-2.08）。空气污染控制对健康和健康公平具有长期的积极影响。最贫困人口是空气污染控制的主要受益者，这表明政策制定者应努力减少空气污染控制中的健康不公平现象。

期刊介绍： ACS Applied Bio Materials is an interdisciplinary journal publishing original research covering all aspects of biomaterials and biointerfaces including and beyond the traditional biosensing, biomedical and therapeutic applications. The journal is devoted to reports of new and original experimental and theoretical research of an applied nature that integrates knowledge in the areas of materials, engineering, physics, bioscience, and chemistry into important bio applications. The journal is specifically interested in work that addresses the relationship between structure and function and assesses the stability and degradation of materials under relevant environmental and biological conditions.
