Nationwide Study for Epidemiological Change of Atopic Dermatitis in School Aged Children between 1995 and 2000 and Kindergarten Aged Children in 2003 in Korea / 소아알레르기및호흡기학회지

ABSTRACT

OBJECTIVE: Atopic dermatitis is a chronically relapsing inflammatory skin disease. However, little is known about the prevalence of atopic dermatitis outside of North America and Europe. We evaluated the nationwide prevalence of atopic dermatitis with the comparison of prevalence between 1995 and 2000, and between Seoul and provincial cities in Korea. We also evaluated the risk factors for atopic dermatitis. METHODS: A cross-sectional ISAAC based questionnaire survey was conducted on random samples of schoolchildren (6 to 15 year olds) in 1995 and 2000. And kindergarten children (5 year olds) were surveyed in 2003, throughout South Korea. RESULTS: The lifetime and last twelve months prevalence of atopic dermatitis in Korean school-aged children was increased from 1995 to 2000. The twelve-month prevalence of atopic dermatitis was higher in Seoul than in other provincial cities in 1995, but the prevalence of atopic dermatitis in Seoul and Provincial Centers became similar in 2000. CONCLUSION: The prevalence of atopic dermatitis in Korean school-aged children was increased from 1995 to 2000. The further evaluations that include objective examination are necessary to confirm these outcomes because the environmental and risk factors may be different among the countries according to their life styles.
