A study on the relationships between ambient air pollutants (PM2.5, SO₂ and NO₂) and hospital emergency room visits (ERVs) for respiratory diseases from 2013 to 2014 was performed in both urban and suburban areas of Jinan, a heavily air-polluted city in Eastern China. This research was analyzed using generalized additive models (GAM) with Poisson regression, which controls for long-time trends, the "day of the week" effect and meteorological parameters. An increase of 10 μg/m³ in PM2.5, SO₂ and NO₂ corresponded to a 1.4% (95% confidence interval (CI): 0.7%, 2.1%), 1.2% (95% CI: 0.5%, 1.9%), and 2.5% (95%: 0.8%, 4.2%) growth in ERVs for the urban population, respectively, and a 1.5% (95%: 0.4%, 2.6%), 0.8% (95%: -0.7%, 2.3%), and 3.1% (95%: 0.5%, 5.7%) rise in ERVs for the suburban population, respectively. It was found that females were more susceptible than males to air pollution in the urban area when the analysis was stratified by gender, and the reverse result was seen in the suburban area. Our results suggest that the increase in ERVs for respiratory illnesses is linked to the levels of air pollutants in Jinan, and there may be some urban-suburban discrepancies in health outcomes from air pollutant exposure.
2013年至2014年期间，在中国东部空气污染严重的济南市的市区和郊区，开展了一项关于环境空气污染物（PM2.5、SO₂和NO₂）与呼吸系统疾病医院急诊就诊量（ERVs）之间关系的研究。本研究采用广义相加模型（GAM）及泊松回归进行分析，该模型控制了长期趋势、“星期几”效应和气象参数。对于城市人口，PM2.5、SO₂和NO₂每增加10 μg/m³，分别对应ERVs增长1.4%（95%置信区间（CI）：0.7%，2.1%）、1.2%（95%CI：0.5%，1.9%）和2.5%（95%：0.8%，4.2%）；对于郊区人口，分别对应ERVs增长1.5%（95%：0.4%，2.6%）、0.8%（95%：-0.7%，2.3%）和3.1%（95%：0.5%，5.7%）。按性别分层分析时发现，市区女性比男性对空气污染更敏感，而郊区则出现相反结果。我们的研究结果表明，济南市呼吸系统疾病的ERVs增加与空气污染物水平有关，并且在空气污染暴露的健康结果方面可能存在一些城乡差异。
