ABSTRACT
There is geographic variability in the prevalence of asthma. Since there is inadequate of study on asthma in Iran, this study was performed in order to determine the prevalence of asthma in Kurdistan province. This cross-sectional study was performed as part of Iranian national survey to determine the risk factors of non communicable disease. This study includes 500 men and 500 women. Prevalence of history of asthma was 2.3%. There was no statistically significant association between asthma and place of residence, smoking and body mass index. Asthma were found in 6 [1.8%] of men and 17 [5%] of women [p=0.02]. Prevalence of asthma increased with increasing age [p<0.001]. The prevalence of asthma in this study was similar with other studies in Iran and seems lower than similar countries
