Abstract
ObjectiveTo analyze the effect of O3 pollution on outpatient visits for respiratory diseases in a district of Shanghai.MethodsWe collected the respiratory disease outpatient dataï¼ 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.ResultsThe 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% ï¼95%CIï¼ 0.240%â0.682%ï¼ at lag3. Stratified by gender and ageï¼ femalesï¼ child and the aged had higher risk of respiratory diseases. In the double-pollutant modelï¼ PM2.5 and PM10 increased health effectsï¼ while CO reduced health effects.ConclusionThe increase of O3 concentration can increase the daily outpatient volume of respiratory diseases.
