Asthma in childhood is a chronic disease and, when unadorned, often results in augmented morbidity for the enduring and indirect economic fatalities for the community. Geographical location, environmental, ethnicity, as well as dynamics related to behaviours and lifestyles are allied with the disease. 1 Asthma is a syndrome characterized by airflow obstruction that differs strikingly, both instinctively and with treatment. Asthmatics anchorages a distinct type of inflammation in the airways that makes them more receptive than nonasthmatics to a wide assortment of triggers, leading to excessive narrowing with consequent reduced airflow and symptomatic wheezing and dyspnea. 3-6 Narrowing of the airways is usually reversible, but in some patients with chronic asthma there may be an ABSTRACT Background: Asthma in childhood is a chronic disease and, when unadorned, often results in augmented morbidity for the enduring and indirect economic fatalities for the community. The predominance of childhood bronchial asthma being amplified in developing countries like India due to rapid urbanization is imposing a challenge to health sector. This study aims to determine the prevalence of bronchial asthma and socio-demographic factors influencing the bronchial asthma among the school children in the field practice area. Methods: A cross-sectional study was conducted in secondary schools in Davangere district, by utilizing International Study of Asthma and Allergies in Children (ISAAC) questionnaire tool for period of two months. Total of 550 school students were examined from the four schools of Davangere, two belonging to rural field practice area and two belonging to urban field practice area of J.J.M medical college, Davangere by using simple random selection. Results: On the basis of ISAAC scoring, 25 (4.5%) were found to be the cases of asthma. Boys had a higher prevalence (5.14%) than girls (3.77%). Maximum numbers of positive cases were found at the age of 15 years, 10 (5.37 %) cases. Out of the 25 positive cases, 8 (32%) had wheezing or whistling in the chest in the past 12 months. Among 25 positive cases, from last 12 months, 6 children (24%) had attack of wheezing, maximum number of children had 4-12 times (67%) attack of wheezing. Conclusions: Our data suggest that the actual prevalence of asthma and other 'wheezy' illnesses may be higher than that previously documented. Further studies are needed to confirm the difference in prevalence between urban and rural children and also to identify possible causes that could account for the higher urban prevalence in Davangere
