Распространенность бронхиальной астмы в Свердловской области

The aim: to reveal bronchial asthma (BA) spread on the basis of different risk factors for the disease and of regional features, to develop an algorithm for determination of BA prevalence at a large industrial region. We asked 2045 citizens using the random method and the verifying questionnaire ECRHS . Answers were given by 1572 (76.9%) respondents, their mean age was 40.1±0.3 years, 837 females were among them. Air pollutants (N0 2 , S0 2 , CO) concentrations were detected. Bronchial hyperreactivity (BHR) and bronchial obstruction (BO) were estimated in 288 subjects. The most typical asthma-like symptom was "loaded or sibilant breathing during the last year" (31.3% of the positive answers). A dependence of asthma-like symptoms frequency on the air pollutants concentration and nose allergic diseases was determined. BO and BHR were revealed in 14.3% of the cases. The BA spread at the large industrial region was 6.2% in total (6.9% for males and 5.5% for females). An optimized method for BA prevalence detection at a large industrial region was developed.
