Abstract

Objective To explore the relationship between children asthma exacerbation and air pollution and meteorological factors in Wenzhou city. Methods The data of hospitalized children with asthma exacerbation were collected in Wenzhou city from July 2013 to June 2014 and the data of the local air pollution and meteorological factors were collected in the same period too.Then the relationship between asthma exacerbation number and air pollution and meteorological factors were analyzed by straight line correlation,multi-variant linear stepwise regression methods. Results Asthma exacerbation number seemed to go up as air pollution got worse.Inhalable particles (pm10) was the major impact index and had the most significant correlation with the number asthma exacerbation children. Conclusions pm10 is an important factor to affect children developing asthma exacerbation in Wenzhou city,especially to cases of simple asthma exacerbation.Environmental protection should be done well to reduce the incidence of asthma exacerbation in children.
