Abstract:
Objective To investigate the correlation between the concentration of air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases in a general hospital in Shanghai. Methods Data including pediatric respiratory disease outpatient and emergency visits in a hospital in Pudong New Area of Shanghai from May 1, 2013 to March 20, 2022 were collected. Daily concentration of air pollutants including PM10, SO2 and NO2 and meteorological data in Pudong New Area during the same period were collected. A case-crossover study with distributed lag non-linear model was conducted to explore the correlation between air pollutants (PM10, SO2, NO2) and the number of outpatient and emergency visits for pediatric respiratory diseases. Results The concentrations of PM10, SO2 and NO2 were positively with the number of outpatient and emergency visits for pediatric respiratory diseases. The strongest cumulative effect was observed on six days lag (Lag0-5) for PM10. For a 10 μg/m3 increase of the concentrations of PM10, the corresponding increase of cumulative pediatric respiratory disease outpatients was 1.10% (95%CI:0.97%, 1.23%) in Lag0-5. The strongest cumulative effect was observed on eight days lag (Lag0-7) for SO2 and NO2. For a 10 μg /m3 increase of the concentrations of SO2 and NO2, the corresponding increase of cumulative pediatric respiratory disease outpatients was 5.64% (95%CI:5.16%, 6.13%) and 5.41% (95%CI:5.15%, 5.66%) in Lag 0-7, respectively. The association of PM10 and SO2 with the number of pediatric respiratory disease visits in males was significantly stronger than that in females. The impact of PM10 on the number of pediatric respiratory disease visits in children aged 0-6 was higher than that in children aged 7-14, while the impact of SO2 and NO2 on the number of pediatric respiratory disease visits in children aged 7-14 was higher than that in children aged 0-6. Conclusion The concentration of ambient PM10, SO2, and NO2 is positively correlated with outpatient and emergency visits for pediatric respiratory diseases, with obvious lag and cumulative effect. Boys and children aged 0-6 are more susceptible to the hazard of air pollution.
