Title

Asthma and Climatic factors in Kermanshah

English Abstract

Background:asthma is considered as one of thesignificant challenges of public health.In this study,the association between climatic factors, with increasing the number of hospitalization of asthmatic patients in Kermanshah was examined. Methods: This study isboth a cross-sectional and ecological analysis. A number of asthma hospital admissions were collected during 2008-2009 from 7 major hospitalsof Kermanshah. At this time, data of meteorological data (temperature, air pressure, relative humidity and rainfall) were obtained from Meteorological Organizationof Kermanshah.In order to measure the correlation between the parameters, Pearson'sbivariate correlation was used and to determine the relationship ofhospital admission of asthmatic patientswith climatic factors, GLM (Generalized Linear Model) and Poisson regression at a significance level (P value = 0.05) were applied. Results:Bivariate correlation showed that climatic factors have mutually a significant correlation with each other.Temperature with pressure and humidity were correlated by a factor of -061 and -0.8,respectively;also,pressure and humidity by a factor of 0.51 have a significant positive correlation.TheResults of Poisson regression showedthe relative risk of asthma hospitalization was (95% CI: 0.953-0.994) fortemperature. Conclusion: Based on the results among climatic factors,low temperature and cold weather were significantly associated with asthma exacerbations. However, due to the multi-factorial nature of asthma, there are other factors that also play a major role in the development and exacerbation of asthma hospitalization.
