    郑州市空气污染与儿童医院呼吸系统日门诊量的相关性

    Association between Air Pollution and Daily Outpatient Visits of Respiratory System in Children Hospital of Zhengzhou

      摘要
    • 摘要:
      目的 探讨空气污染与儿童医院呼吸系统门诊量间的关系。
      方法 应用时间序列分析广义线性模型，对2013—2014年郑州市儿童医院呼吸系统门诊量、郑州市大气监测点的空气污染监测资料及郑州市气象资料进行大气污染与儿童医院呼吸系统门诊量的相关性分析。
      结果 Spearman秩相关分析得PM10、PM2.5、NO2和SO2与呼吸系统门诊量呈正相关（P < 0.01）；PM10浓度每增10 μg/m3，当日呼吸系统门诊量增加0.72%；PM2.5浓度每增加10 μg/m3，当日呼吸系统门诊量增加0.90%；NO2浓度每增10 μg/m3，当日呼吸系统门诊量增加7.73%，在累积滞后（0~5）d时效应最强，超额危险度（ER）为9.88%；SO2浓度每增10 μg/m3，当日呼吸系统门诊量增加2.92%，且在累积滞后（0~3）d时效应最强，ER为3.22%。
      结论 郑州市的空气污染物能增加儿童医院呼吸系统门诊量。

       

      Abstract:
      Objectives To study the correlation of air poilution and daily outpatient visits of respiratory system disease.
      Methods The following data were collected from the outpatient visits of respiratory system disease in Children Hospital of Zhengzhou from 2013 to 2014, the air monitoring data from Environmental Monitoring sites in Zhengzhou, and the meteorological data from Zhengzhou. The time-series analysis was adopted to analyze the generalized linear model in order to study the association between air pollution and children outpatient visits.
      Results The hospital outpatient visits of respiratory system was significantly positively correlated with PM10, PM2.5, NO2, and SO2 according to the Spearman correlation analysis (P < 0.01); an increase of 10 μg/m3 in concentrations of PM10 could increase the hospital outpatient visits of respiratory system disease by 0.72%; an increase of 10 μg/m3 in concentrations of PM2.5 could increase the hospital outpatient visits of respiratory system disease by 0.90%;an increase of 10 μg/m3 in concentrations of NO2 could increase the hospital outpatient visits of respiratory system disease by 7.73%, the strongest ER effect is 9.88% with (0~5) d accumulated delay; an increase of 10 μg/m3 in concentrations of SO2 could increase the hospital outpatient visits for respiratory system by 2.92%, the strongest excess risk(ER) effect is 3.22% with (0~3) d accumulated delay.
      Conclusions The concentration of air pollutants could increase daily outpatient visits of respiratory system in children hospital of Zhengzhou City.
