ABSTRACT
The impact of ambient air pollution on the prevalence of main symptoms of asthma was analyzed in children. A total of 3,506 children were interviewed using the ISAAC questionnaire. The prevalence of the abnormality was studied via continuous questioning in children aged 7-8 and 13-14 years, who lived in areas with varying aerogenic loads. The higher rates of main asthma-like symptoms and clinically diagnosed asthma were ascertained in the children living in higher ambient air pollution areas.

The study of the predictors impacting the development of bronchial asthma in children was implemented. For each risk factor the chances ratio and its 95% confidence interval were calculated. The sample consisted of 280 children with bronchial asthma aged from 7 to 14 years and 210 healthy children of the same age. The risk factors having priority significance for the development of bronchial asthma in children are identified. The research data can be applied to calculate of the individual risks in population to forecast the development of bronchial asthma and its timely prevention.
