摘　　要：【目的】分析上海市某郊区大气污染物臭氧(O_(3))与居民呼吸系统日门诊量的关系。【方法】收集2015—2017年上海市某郊区综合医院呼吸系统门诊资料和同期大气、气象资料,采用时间序列的半参数广义相加模型(GAM)分析大气污染物O_(3)浓度与居民呼吸系统日门诊量的关系。【结果】呼吸系统日均门诊量为831人次。O_(3)最大8 h平均值为101.04μg·m^(-3)。O_(3)在lag3的滞后效应最大,超额危险度为0.461%(95%CI:0.240%~0.682%)。分层分析结果显示,O_(3)对女性、儿童、老年人呼吸系统影响风险更高。引入PM_(2.5)、PM_(10)到双污染物模型中表现为健康效应增强,引入一氧化碳表现为健康效应减弱。【结论】O_(3)浓度的升高可引起人群呼吸系统日门诊量的增加。[Objective]To analyze the effect of O_(3) pollution on outpatient visits for respiratory diseases in a district of Shanghai.[Methods]We collected the respiratory disease outpatient data,and atmospheric and meteorological data of from a suburban general hospital in Shanghai from 2015 to 2017.A time-series analysis by generalized additive model was conducted to examine the relationship between O_(3) pollution and daily outpatient visits.[Results]The daily outpatient volume for respiratory diseases was 831.The daily 8 h median concentration of O_(3) was 101.04μg·m^(−3).The excess relative risk was 0.461%(95%CI:0.240%‒0.682%)at lag3.Stratified by gender and age,females,child and the aged had higher risk of respiratory diseases.In the double-pollutant model,PM_(2.5) and PM_(10) increased health effects,while CO reduced health effects.[Conclusion]The increase of O_(3) concentration can increase the daily outpatient volume of respiratory diseases.
