Abstract
The prevalence of bronchial asthma (BA) in recent years has been steadily increasing in many countries of the world. Among allergic diseases and respiratory diseases, asthma occupies a leading position. In order to study the prevalence of asthma, we performed questionnaire survey of 6326 schoolchildren, including 3125 cases aged of 7-8 years and children of 13-14 years according to the «ISAAC» program. The prevalence of bronchial asthma in children in the mountain climate is about 8.43 per 1,000 children, which is almost two times lower than in the low-lying zone, in urban children the prevalence of bronchial asthma is 25 per 1000 children. Among the risk factors for the formation of bronchial asthma in children the leading place is occupied by hereditary, occupy antenatal and social sanitary risk factors.
