Although evidence showed the adverse effects of air pollution on cardiovascular disease (CVDs), few studies were based on medically insured populations. We applied a generalized additive Poisson model (GAM) to estimate the short-term effects of ambient air pollution on a group of medically insured population in Wuhan, China. We extracted daily air pollution data, meteorological data, and daily hospital visits for CVDs. We found that the ambient air pollutants sulfur dioxide (SO), nitrogen dioxide (NO), ground-level ozone (O) particulate matter (PM) with an aerodynamic diameter ≤10 μm (PM), and those ≤2.5 μm (PM) all increased the risk of daily hospital visits for CVDs. We also found that the effect of air pollution on daily hospital visits for CVDs is greater in the cold season than in the warm season. Our findings can be used as evidence that supports the formulation of policies for air pollution and CVDs.
尽管有证据表明空气污染对心血管疾病（CVDs）有不良影响，但基于参保人群的研究却很少。我们应用广义相加泊松模型（GAM）来估计环境空气污染对中国武汉一组参保人群的短期影响。我们提取了每日空气污染数据、气象数据以及心血管疾病的每日就诊人数。我们发现，环境空气污染物二氧化硫（SO）、二氧化氮（NO）、地面臭氧（O）、空气动力学直径≤10μm的颗粒物（PM）以及≤2.5μm的颗粒物（PM）均增加了心血管疾病每日就诊的风险。我们还发现，空气污染对心血管疾病每日就诊的影响在寒冷季节比温暖季节更大。我们的研究结果可作为支持制定空气污染与心血管疾病相关政策的证据。
