    大气O3污染对石家庄市呼吸系统疾病急救人次的急性影响

    Acute Effects of Ozone Pollution on Daily Emergency Ambulance Dispatches Due to Respiratory Diseases in Shijiazhuang

      摘要
    • 摘要:
      目的  探讨石家庄市大气O3-8 h浓度与该市居民呼吸系统疾病急救人次的关系。
      方法  收集该城市2013年1月1日-2014年12月31日的O3-8 h浓度、日均气温和相对湿度、以及每日呼吸系统疾病急救人数，采用广义相加时间序列模型，控制每日非意外总就诊量的长期趋势、气象因素、“星期几效应”和节假日效应等混杂因素后，分析大气O3浓度与每日呼吸系统疾病急救人次的关系。
      结果  大气中O3浓度每升高10 μg/m3(lag1)，该市居民因呼吸系统疾病呼叫急救的人数增加1.20%（95% CI：0.36%~2.04%）；季节分层分析结果表明，该市居民呼吸系统疾病急救的风险存在显著的季节差异（P<0.05）。
      结论  大气O3污染，尤其是夏季污染可能增加居民因呼吸系统疾病的风险。

       

      Abstract:
      Objective  To access the relationship between ambient maximum 8-h average concentration of ozone and daily emergency ambulance dispatches due to respiratory diseases in Shijiazhuang.
      Methods  Semi-parametric generalized additive model was used to analyze the relationship between O3-8h concentration and daily emergency ambulance dispatches due to respiratory diseases from January 1, 2013 to December 31, 2014 in Shijiazhuang after adjustment for time trends, weather conditions and "days of the week".
      Results  An 10ug/m3 increase in the lag1 day concentration of O3-8h corresponded to increase of 1.20%(95% CI:0.36%~2.04%) in daily emergency ambulance dispatches due to respiratory diseases. The effects of ozone pollution on daily emergency ambulance dispatches due to respiratory diseases were restricted in the warm season in Shijiazhuang.
      Conclusions  Our research indicates that outdoor O3-8h concentration is significantly associated with increased risk of emergency ambulance dispatches due to respiratory diseases in Shijiazhuang.
