摘要/Abstract

摘要： 目的分析2019年天津市河北区气态污染物对冠心病住院人次的影响及滞后效应。方法收集2019年1月1日—12月31日天津市河北区气态污染物浓度、气象因素及天津市第四中心医院冠心病住院患者的相关信息，采用广义加性模型分析探讨气态污染物对居民冠心病住院人次的影响。结果 2019年天津市河北区气态污染物NO₂、O₃、SO₂和CO日均浓度分别为42.17 μg/m³、106.23 μg/m³、10.85 μg/m³和0.96 mg/cm³。按照GB 3095—2012《环境空气质量标准》规定的二级浓度限值，NO₂共超标164 d，超标率为44.93%;O₃共超标81 d，超标率为22.19%;SO₂和CO均未超标。NO₂暴露浓度每增加10 μg/m³对冠心病住院人次的影响在滞后1 d时达到最大，超额危险度（excess rish，ER）值为3.35（95%CI：0.28~6.52），差异有统计学意义（P<0.05）;O₃暴露浓度每增加10 μg/m³对冠心病住院人次的影响在滞后7 d时达到最大，ER值为-1.28（95%CI：-2.29~-0.25），差异有统计学意义（P<0.05）。CO和SO₂浓度的增加对冠心病住院人次无影响。结论 2019年天津市河北区气态污染物NO₂浓度升高可能导致居民冠心病住院风险增加，控制气态污染物对降低人群冠心病住院风险具有重要意义。

Abstract: Objective To analyze the effect and lag effect of gaseous pollutants on the number of inpatients with coronary heart disease（CHD） in Hebei District of Tianjin in 2019. Methods The concentration of gaseous pollutants，meteorological factors and relevant information of inpatients with CHD in Tianjin Fourth Central Hospital from January 1，2019 to December 31，2019 were collected. The effect of gaseous pollutants on the number of inpatients with CHD was analyzed by generalized additive model. Results The average daily concentrations of gaseous pollutants NO₂，O₃，SO₂ and CO in Hebei District of Tianjin in 2019 were 42.17μg/m³，106.23 μg/m³，10.85 μg/m³ and 0.96 mg/cm³. According to the secondary concentration limit specified in the Ambient Air Quality Standard（GB 3095-2012），NO₂ exceeded the standard for 164 days，with theoverstandard rate of 44.93%. The O₃ exceeded the standard for 81 days，and the overstandard rate was 22.19%. Neither SO₂ nor CO exceeded the standard. The effect of NO₂ concentration increasing by 10 μg/m³ on the number of inpatients with CHD reached the maximum after 1 day lag，theexcess rish（ER） value was 3.35（95%CI：0.28-6.52），and the difference was statistically significant（P<0.05）. The effect of O₃ concentration increasing by 10 μg/m³ on the number of inpatients with CHD reached the maximum when the delay was 7 days，the ER value was -1.28（95%CI：-2.29--0.25），and the difference was statistically significant（P<0.05）. The increase of CO and SO₂ concentration had no effect on the number of inpatients with CHD. Conclusion The elevated concentration of gaseous pollutant NO₂ in Hebei District of Tianjin in 2019 may lead to an increase in the risk of hospitalization for CHD among residents，and it is of great significance to control gaseous pollutants for reducing the hospitalization risk of CHD.
