    Abstract
  •   Objective  To evaluate the association between air pollutants and acute upper respiratory tract infections (AURTI) in the emergency department of Hefei City.  Methods  Emergency hospital visits for AURTI in public hospitals in Hefei from January 1, 2016 to December 31, 2020, meteorological data and air pollutants data for the same period were collected for the study.After controlling for confounding factors such as meteorological factors, day-of-week effects and holiday effects, the distribution lag nonlinear model was used to quantify the association between daily air pollutants and daily emergency visits.The results were then stratified by gender and age.  Results  The total number of AURTI emergency department visits in Hefei from 2016 to 2020 was 55 902, and it is higher in the cold season than in the warm season.Among all pollutants, SO2 had the greatest effect on AURTI, with its lag effect reaching a maximum at lag07, with a RR and 95%CI of 1.194(1.072-1.330).The relative risks (RR) of gaseous pollutants (SO2, NO2) were higher than those of particulate matter (PM2.5, PM10).Gender stratification showed that females seemed to be more vulnerable to exposure to SO2 and NO2, while males were more vulnerable to PM2.5, PM10 and O3.In the age stratification, people aged >65 years were more sensitive to PM2.5, PM10 and NO2, people aged 18-65 years were more sensitive to SO2.  Conclusion  Elevated concentrations of air pollutants in Hefei all increased the risk of emergency admissions for AURTI, with different patterns of effects by gender and age.
