Aim. To study the prevalence of bronchial asthma (BA) symptoms among elementary schoolchildren in the Udmurt Republic in the dynamics over 20 years.
Materials and methods. A comparative study of the prevalence of BA was carried out. A questionnaire was administered to 2899 parents of first-graders, using the international standardized ISAAC program.
Results. The prevalence of BA symptoms on the ISAAC program among elementary schoolchildren in the Udmurt Republic in 2020 was 7.70.2%, being significantly lower than in the previous studies of 2002 and 2009 (p0.001).
Conclusion. There was a further downward trend in the prevalence of AD symptoms in younger schoolchildren. The difference between the current symptoms of the disease and the established diagnosis remained rather significant. Reliable (p10.001) increase in the number of children with dry cough, not related to cold, and children with bronchospasm connected with physical load was revealed.
