摘要
目的了解珠海市大气PM2.5浓度与医院儿科呼吸系统疾病门诊日就诊人次的关系。方法收集珠海市2013—2016年大气污染物浓度数据及同期气象资料和两家医院逐日就诊资料,采用时间序列广义相加模型(GAM)分析2013—2016年珠海市大气PM2.5日均浓度与医院儿科呼吸系统疾病门诊日就诊人次的关系及其滞后效应。结果 2013—2016年珠海市大气PM2.5日均浓度为32.16μg/m3,大气PM2.5浓度与PM10、SO2、NO2、CO和O3浓度均呈正相关(rs值分别为0.94,0.81,0.72,0.63,0.47,P<0.05)。单污染物模型显示,大气PM2.5浓度每升高10μg/m3,当日儿科呼吸系统疾病门诊就诊人次增加2.47%(95%CI:1.93%~3.02%);双污染物模型(PM2.5+CO、PM2.5+O3)中,大气PM2.5浓度每升高10μg/m3,当日儿科呼吸系统疾病门诊就诊人次的ER值分别为1.67%(95%CI:1.03%~2.31%)和2.53%(95%CI:1.94%~3.13%);多污染物模型(PM2.5+CO+O3)中,PM2.5在滞后4 d时效应最大,PM2.5浓度每升高10μg/m3,儿科呼吸系统疾病门诊人次增加1.90%(95%CI:1.26%~2.54%)。结论珠海市大气PM2.5浓度与儿科呼吸系统疾病门诊就诊人次有一定关系。
Objective To understand the relationship between the concentration of the air PM2.5 and daily outpatient visits of children respiratory disease.Methods The same period atmospheric pollutants data,meteorological data and daily outpatient visits of children respiratory diseases in two hospitals,from 2013 to 2016 in Zhuhai were collected to analyze the distribution characteristics and their correlation with meteorological factors,and a time series semi-parametric generalized additive model(GAM)was used to analyze the exposure-effect relationship between atmospheric pollutants and daily outpatient visits of children respiratory diseases.Results The average concentration of PM2.5 was 32.16μg/m3 from 2013 to 2016 in Zhuhai.PM2.5 was positively correlated with PM10,SO2,NO2,CO and O3,the related corresponding correlation coefficients were 0.94,0.81,0.72,0.63 and 0.47,respectively(P<0.05).In the single pollutant regression model,with every 10μg/m3 increase of ambient PM2.5,the corresponding excess risk of daily outpatient visits of children respiratory diseases was 2.47%(95%CI:1.93%-3.02%).In the two-pollutant regression model(PM2.5+CO and PM2.5+O3),with every 10μg/m3 increase of ambient PM2.5,the corresponding excess risks of daily outpatient visits of children respiratory diseases were 1.67%(95%CI:1.03%-2.31%)and 2.53%(95%CI:1.94%-3.13%)respectively.In the three-pollutant regression model(PM2.5+CO+O3),with every 10μg/m3 increase of ambient PM2.5,the corresponding maximum excess risk of daily outpatient visits of children respiratory diseases(lag4)were 1.90%(95%CI:1.26%-2.54%).Conclusion The concentration of air PM2.5 has a significant correlation with daily outpatient visits of children respiratory diseases in Zhuhai.
