先前的研究表明，环境空气污染与呼吸道疾病有关。然而，中国很少研究空气污染物对健康的影响。我们的研究旨在评估颗粒空气污染物对三种呼吸系统疾病住院治疗的短期影响：肺炎、慢性阻塞性肺病（COPD）和哮喘。我们收集了中国合肥新型农村合作医疗系统（NRCMS）中每种疾病患者每日入院的数据。还获得了2014年1月至2016年3月的空气污染物每日记录和气象数据。分析中采用分布滞后非线性模型来评估每日空气污染物与入场人数之间的关联。每种污染物对 COPD 入院的影响最大的是 PM2.5 在滞后 12 时（RR = 1.068，95% CI 1.017 至 1.121）和 PM10 在滞后 10 时（RR = 1.031，95% CI 1.002 至 1.060），污染物浓度增加 10 µg/m3in。 PM10 对哮喘入院的短期影响在滞后 12 时达到峰值（RR = 1.057，95% CI 1.010 至 1.107）。根据我们的分层分析，我们发现温暖季节对 COPD 入院的影响比寒冷季节更明显，而且老年人（≥65 岁）和女性更容易受到空气污染的影响。
Previous studies have shown that ambient air pollution is associated with respiratory morbidity. However, the effects of air pollutants on health have rarely been studied in China. Our study aimed to estimate the short-term effects of particulate air pollutants on hospitalizations for three types of respiratory disease: pneumonia, chronic obstructive pulmonary disease (COPD), and asthma. We collected data on daily admissions for patients with each disease from the New Rural Cooperative Medical System (NRCMS) in Hefei, China. Daily records of air pollutants and meteorological data from January 2014 to March 2016 were also obtained. Distributed lag nonlinear models were employed in the analysis to evaluate the association between daily air pollutants and admissions. The highest effect of each pollutant on COPD hospital admission was observed with PM2.5at lag 12 (RR = 1.068, 95% CI 1.017 to 1.121) and PM10at lag 10 (RR = 1.031, 95% CI 1.002 to 1.060), for an increase of 10 μg/m3in concentrations of the pollutants. The short-term effects of PM10on asthma hospital admissions peaked at lag 12 (RR = 1.057, 95% CI 1.010 to 1.107). According to our stratified analysis, we found that the effects on COPD admission were more pronounced in the warm season than in the cold season, and the elderly (≥ 65 years) and females were more vulnerable to air pollution.
