Abstract

Background: Industrialization and urbanization have had a devastating impact on public health. Asthma is considered as one of the major challenges of public health. The purpose of this study was to determine the association between air pollution and the number of asthma patients admitted to hospitals in Kermanshah, Iran.
Methods: In this cross-sectional and ecological study, the data on the number of asthma patients, the concentration levels of air pollutants and weather conditions were collected from the city of Kermanshah. To determine the association between asthma patients admitted to hospitals and air pollutants, Poisson regression was used (P<0.05).
Results: according to the statistical analysis, air pollutants had significant correlation with each other. Based on the results of multiple Poisson regression, among air pollutants CO and O3 were significantly correlated with the number of asthma patients referred to hospitals, with relative risk of 1.18 and 1.016, respectively, and based on the results of single Poisson regression, among air pollutants NOx, NO, NO2 and CO were significantly correlated with the number of asthma patients referred to hospitals with relative risk of 1.011, 1.012, 1.054 and 1.247, respectively.
Conclusion: according to the results of the present study, there was a significant association between air pollutants (mainly carbon monoxide and ozone) and the total number of asthma patients referred to the hospitals in Kermanshah.
