Abstract：Objective To understand the impact of air pollutant exposure on the number of children hospitalized for common respiratory diseases. Methods The clinical data of pediatric hospitalized children for common respiratory diseases from January 2009 to December 2016 in Guizhou Provincial People′s Hospital and air pollutant monitoring data at various environmental monitoring points in Guiyang City including: PM2.5, PM10, nitric oxide (NO) and the concentration of sulfur dioxide (SO2) were collected. A typical correlation analysis method was used to analyze the impact of air pollutants on the number of children hospitalized for common respiratory diseases. Results A total of 10 876 hospitalized children with respiratory diseases were included in the study, and the diagnosis was mainly bronchopneumonia (76.31%), with an average hospital stay (9.56±6.05) d. The correlation coefficient between air pollutants and bronchial pneumonia was the highest (r = 0.33, P ＜ 0.001), followed by bronchitis (r = 0.21, P ＜ 0.001) and acute tonsillitis (r = 0.20, P ＜ 0.001). PM10 was the main air pollutant component that affected the number of children for common respiratory diseases. Air pollution one day before hospitalization had the greatest impact on the number of children for common respiratory diseases. Conclusion Ambient air pollutants can affect the number of children hospitalizations for common respiratory diseases, of which the number of hospitalizations for bronchopneumonia is the greatest. Among them, PM10 is the most common pollutant that affects the number of children hospitalizations for common respiratory diseases, and the largest effect is one day before hospitalization.
