【摘要】：目的研究灰霾天气大气污染对广州市儿童呼吸系统症状的影响。方法于2013年10月—2014年8月在广州市选择2所小学4~6年级的676名学生作为研究对象,每个学生每隔14 d随访一次过去两周内有关呼吸系统症状发生的情况,结合同时期的灰霾天气大气污染资料,采用广义线型Poisson回归模型分析了儿童呼吸系统症状与大气污染物浓度及灰霾天数之间的关系。结果单一大气污染因素模型回归分析显示:灰霾天数对咳嗽、咳痰、2周内喘息和2周内咳嗽均表现为正效应,RR值分别为1.018 7、1.013 5、1.005 2、1.006 5,除咳痰症状外差异均有统计学意义;大气污染物(PM10、NO2、SO2)对上述4种呼吸系统症状的RR值均1,具有显著的正效应。多个大气污染因素模型回归分析显示:灰霾天数仅与2周内咳嗽的发生有统计学关联(RR=1.001 6);PM10和NO2每升高10μg/m3仅与咳痰有统计学关联,RR分别为1.084 7和1.005 6;SO2与4种呼吸系统症状均有正向统计学关联。结论灰霾天气大气污染在一定程度上与儿童呼吸系统症状的发生有关。
[Abstract]:Objective to study the effects of haze air pollution on respiratory symptoms of children in Guangzhou. Methods from October 2013 to August 2014, 676 students from 4 to 6 grades in two primary schools were selected as subjects. Each student was followed up every 14 days for the past two weeks. Based on the atmospheric pollution data of haze weather in the same period, the relationship between respiratory symptoms, air pollutant concentration and haze days in children was analyzed by using generalized linear Poisson regression model. Results the regression analysis of single air pollution factor model showed that the positive RR values of haze days in cough, expectoration and expectoration within 2 weeks and cough within 2 weeks were 1.018 卤1.013 5 / 1.005 and 1.0065 respectively, with the exception of expectoration symptoms, the difference was statistically significant. The RR values of PM10 and NO2SO2 on the above four respiratory symptoms were all 1, which showed a significant positive effect. Regression analysis of several air pollution factors showed that the days of haze were only associated with the occurrence of cough within 2 weeks. There was a statistical correlation between RRX 1.006, PM10 and NO2 increasing 10 渭 g/m3 only with expectoration. RR was 1.084 7 and 1.005 6 so 2 and 4 respiratory systems, respectively. All symptoms were positively correlated with each other. Conclusion Air pollution in haze weather is related to respiratory symptoms in children to some extent.
