Abstract

Aim. To study the prevalence of atopic dermatitis symptoms and its relation to bronchial asthma symptoms in children of 7-8 years of age. Methods. 8880 children aged 7-8 years were examined (3000 children - in 2002, 2865 children - in 2006, 3015 children - in 2010). A questionnaire survey for atopic dermatitis symptoms was conducted as a part of international unified program «International Study of Asthma and Allergy in childhood». Results. Significant differences in prevalence of atopic dermatitis symptoms according to the questionnaire survey and as documented in medical charts were determined. The prevalence of atopic dermatitis symptoms has raised from 12.5±0.4% in 2002 to 20.4±1.5% in 2010 (р <0.001). The prevalence of atopic dermatitis symptoms early onset (younger than 2 years of age) decreased from 7.6±1.0 to 4.9±0.8% (p <0.05). The prevalence of atopic dermatitis relapses during the past calendar year increased from 3.2±0.6 to 4.8±0.8% (p <0.05). Meanwhile, the diagnosis of atopic dermatitis was set up in preadolescent children 7-8 years of age fore frequently: to 4.0±0.7% in 2002 compared to 13.8±1.3% in 2010 (p <0.001). The prevalence of atopic dermatitis and bronchial asthma combination increased from 3.4±0.4 to 7.8±1.0% (p <0.001). A strong relation between presence of atopic dermatitis symptoms and bronchial asthma symptoms was discovered (from 0.76 to 1.00, p <0.05). Conclusion. The prevalence of atopic dermatitis symptoms and bronchial asthma symptoms is still growing in preadolescent children 7-8 years of age, a relation between presence of abovementioned diseases symptoms was discovered.
