SCI REP:环境空气污染与儿童下呼吸道疾病的短期影响!

2017-06-30 xing.T MedSci原创

由此可见,这项研究表明短期暴露于PM10、NO2和SO2与增加儿童下呼吸道疾病的数量相关。

空气污染与儿童呼吸道疾病之间相关性的研究结果不一致的。近日,Scientific reports 杂志上发表了一篇研究文章,在该研究中,研究人员调查了环境空气污染物对日常儿童下呼吸道疾病的短期影响。

研究人员收集了中国南京从2014年1月起至2015年4月(452天)期间的每日空气污染物、气象数据以及儿童下呼吸道疾病的数据资料。时间序列回归和广义加法模型被用来评估空气污染物(PM10、PM2.5、NO2,SO2、O3和CO)对儿童下呼吸道疾病的影响。

研究人员发现随着PM10、NO2和SO2浓度的四分位数间距(IQR)增加,每日儿童下呼吸道疾病的6天累积效应显著增加(估计的差异分别为2.8%、4.1%、5.6%,95%可信区间分别为0.6-5.0%、1.2-7%、2.6-8.6%)。然而,PM2.5、O3和CO的浓度IQR没有发现显著的相关性。特别是冬天,PM10、PM2.5、NO2和SO2浓度增加会显著增加儿童下呼吸道疾病(3.6%,1.5-5.7%;2.4%,0.3-4.5%;4.9%,2.9–7%;6.3%,3.7-9%)。此外,PM10、NO2和SO2的估计效应在年龄>27个月的女性均明显高于男性和年龄27个月的女性。

由此可见,这项研究表明短期暴露于PM10、NO2和SO2与增加儿童下呼吸道疾病的数量相关。
