上海市某郊区大气臭氧与居民呼吸系统日门诊量的关系

Association between ozone pollution and daily outpatient visits for respiratory system in a district of Shanghai

摘要

摘要:
目的分析上海市某郊区大气污染物臭氧（O₃）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O₃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。O₃最大8 h平均值为101.04 μg·m^-3。O₃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，O₃对女性、儿童、老年人呼吸系统影响风险更高。引入PM_2.5、PM₁₀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 O₃浓度的升高可引起人群呼吸系统日门诊量的增加。

Abstract:
Objective To analyze the effect of O₃ 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 O₃ pollution and daily outpatient visits.
Results The daily outpatient volume for respiratory diseases was 831. The daily 8 h median concentration of O₃ was 101.04 μg·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 PM₁₀ increased health effects， while CO reduced health effects.
Conclusion The increase of O₃ concentration can increase the daily outpatient volume of respiratory diseases.
