Purpose: Atopic dermatitis (AD) has increased in worldwide and nationwide. However, we do not have well designed randomized national epidemiologic studies, but only some selected data about prevalence of AD. We investigated the prevalence of AD and risk factors in nationwide random children and adolescents of Korea.

Methods: We conducted a questionnaires survey with 1,820 children, aged 6 to 19 years old, nationwide in Korea from 2012 to 2013. The subjects were selected by a stratifying sampling method by school grade and five regions. The population was composed of 914 elementary school, 445 middle school, and 461 high school students. Current AD was defined as having recent AD symptoms within 12 months and diagnosed as AD from physicians ever. Atopic sensitization was described by skin prick test for 18 common allergens.

Results:The prevalence of current AD and recent AD treatment within 12 months in elementary school, middle school, and high school was 18.8%, 14.6%, and 13.4%, and 12.3%, 8.6%, and 9.5%, respectively. Risk factors, based on multivariate analysis, for current AD from merged data included household pet keeping (aOR, 1.35; 95% CI, 0.95-1.89) as well as parental allergic disease (aOR, 1.87; 95% CI, 1.44-2.44), mold exposure during infancy (aOR, 1.42; 95% CI, 1.06-1.89), recent mold exposure within 12 months (aOR, 1.54; 95% CI, 1.16-2.03), and atopic sensitization (aOR, 1.47; 95% CI, 1.12-1.93).

Conclusion: The nationwide prevalence of current AD in elementary school, middle school, and high school students were 18.8%, 14.6%, and 13.4%, respectively. The risk factors for current AD included parental allergic disease, mold exposure during infancy, recent mold exposure within 12 months, atopic sensitization, and household pet keeping.
