Background: Widespread, medical and social consequences, impact on quality of life and the significant cost of allergic diseases justify a number of measures for the prevention of diseases. What is clear is that official statistics may not match the true prevalence of allergic diseases in general, especially asthma. Aim of the study: Estimate the prevalence of asthma and allergic diseases, the main symptoms of allergic and respiratory among urban and rural children aged 6–7 years and 13–14 years in the Grodno region carried out in accordance with internationally recognized research methodology. Material and methods: The survey questionnaire (based on a survey ISAAC) 2187 was attended by parents of children 6–7 years and 13–14 years of Grodno and region (1091 children from the city, and in 1096 from the village). 955 children aged 6–7 years, 1232 at the age of 13–14 years. Knowing this with asthma may be suspected in patients, who feel shortness of breath accompanied by wheezing, tightness in the chest or cough and allergic diseases (allergic rhinitis and atopic dermatitis), analyzed the incidence of these symptoms and diseases among children.Results: Demonstrated a low incidence of asthma among children in the age group of standardized. Parents of 30 children (1.37% respondents) confirms the existence of disease in children under physician diagnose disease. Prevalence of asthma among urban children was 1.74% (19 people) and rural – 1.0% (11 children). With a deeper analysis of responses established with 60 children (2.74%) had in the last 12 months wheezing in the chest and coughing. The incidence of allergic rhinitis and atopic dermatitis is about 4% and 10%. These diseases often found only among children with asthma. Conclusions: Since the identification of asthma in children based on the diagnosis by the doctor is not high, can’t be excluded that this reflects a failure to recognize the disease. Noted marked differences in the prevalence of respiratory symptoms, manifesting linking asthma and asthma with allergic diseases. It seems necessary to continuously monitor these phenomena through the continuation of epidemiolog-ical studies as a basis for the development of information and implementation of prevention programs and epidemiological evaluation of the effectiveness of prevention at regional and international.
