Background: Asthma is one of the most common chronic disease affecting children. The recent rise in prevalence of asthma was associated with environmental pollution, urbanization, and the change in demography. The present study was undertaken to determine the prevalence of asthma in Tumakuru urban school children and to study its association with different epidemiological factors. Our study is a questionnaire-based study [International Study of Asthma and Allergies in Childhood (ISAAC)-Questionnaire] carried out in four randomly selected rural schools of Tumakuru district.
