RESUMEN
Case representative selective study of children from 1 to 15 years old age in Batumi, with 2110 children population has been carried out. Risk factors were studied by interviewing method, using two step estimation (on the basis of primary and secondary questionnaire) of the disease developing risk. For statistical analysis of the data SPSS v. 12 was used. Study findings confirm causal connection (with high relative risk) and significant probability of the disease (with high attributive risk), with "major risk factors": allergic diseases and atopic dermatitis in relatives and with "minor risk factors": allergic rhinitis. Relatively weak risk factors (with low relative risk), but with high prevalence in child population in Batumi were found: respiratory infections and bottle-feeding. Revealing individual and population risk phenomenology of bronchial asthma in children population in Batumi, on the basis of that the most of risk factors can be monitored, will promote asthma prevention and population health care, which is more rational and cost-effective.
