AB  - Background: The study of the asthma epidemiology according to the ISAAC program (Phase Three) was over in 2002. Afterwards the studies with the use of standardized methods have not been carried out in the world.Aim: To study the dynamics of asthma prevalence among the 6-7 years old children in the Novosibirsk.Methods: According to the ISAAC 3249 children were examined in 2002 and about 3000 children aged 6-7 years old were examined in the years of 2011-12. This abstract introduce the preliminary results based on the questioning of 970 parents in the years of 2011-12.Results: There decreased the prevalence of wheezing from 24,1% to 17,3% (p<0,0001), the prevalence of current asthma symptoms from 10,8% to 6,3% (p<0,0001), the number of exacerbations over 12 times a year from 0,5% to 0,2% (p=0,001). The prevalence of nocturnal asthma symptoms decreased from 4,3% to 2,2% (p=0,001), the number of symptoms limiting speech decreased from 0,9% to 0,1% (p=0,012). The diagnose of asthma was established in 2,4% of children in 2002. In 2011-12 this percentage increased up to 3,4% (p=0,07), this indicates the improvement in the diagnostics and the better level of knowledge of physicians about the asthma. The prevalence of asthma symptoms associated with the physical exertion was not significantly changed (3,6% in 2002 and 3,3% in 2011-12, p=0,4). The registration of nocturnal cough not associated with the infection of the respiratory tract decreased from 8,6% to 7,6% (p=0,2).Conclusion: The obvious trend in the first decade of the XXI century is the decrease in the prevalence of the asthma symptoms among 6-7 years old children in the Novosibirsk with some improvement in the disease diagnostics.
