Studies about the correlation of air pollutants and hospitalization rate of children respiratory disease in Shijiazhuang city

Abstract

Objective To investigate the relationship between air pollutants and hospitalization rate of children with respiratory disease (asthmatic attack, asthmatoid bronchitis, neumonia) in Shijiazhuang city. Methods The data of air quality monitoring in Shijiazhuang in Hebei Province from January 2016 to December 2016 were recorded, and hospitalization rate of children respiratory disease (asthmatic attack, asthmatoid bronchitis, pneumonia) in Hebei Children′s Hospital were enrolled, and the analysis of the linear regression was done for the correlation of air pollutants and hospitalization rate of children respiratory disease. Results The analysis result showed that the asthmatoid bronchitis hospitalization rate was positively correlated with the average concentration of SO2 and NO2, the correlation coefficient was 0.598 and 0.626 (P<0.05). The results showed that the average concentration of PM10, CO, PM2.5 and O3 did not have linear correlation with asthmatoid bronchitis hospitalization rate.The pneumonia hospitalization rate was positively correlated with the average concentration of SO2, NO2, PM10, CO and PM2.5, and the correlation coefficient was 0.867, 0.811, 0.825, 0.931 and 0.860, respectively (all P<0.05), but was independent with the average concentration of O3.It showed that if the index of concentration of contaminations increase of 10, hospitalization rate of asthmatoid bronchitis increased 0.1% and increased 2.4% of pneumonia. Conclusions The increase of PM10, PM2.5, NO2, SO2 and CO air pollutants could make a corresponding increase in the hospitalization rate of children with respiratory diseases.
