Yu JS, Lee CJ, Lee HS, Kim J, Han Y, Ahn K, Lee SI - J. Korean Med. Sci. (2012)

Bottom Line: In 2008, the prevalence of AD was 26.5% in aged 12-23 months and decreased substantially to 7.6% at age 6 yr, 3.4% at age 12 yr and to 2.4% at age 18 yr.In conclusion, the prevalence of AD in 2008 peaked during infancy up to 26.5% and decreased thereafter.Our findings also suggest that increasing prevalence of AD in children less than 24 months might be responsible for the recent increase in the prevalence of AD in Korean children.

ABSTRACT
We attempted to investigate the prevalence of atopic dermatitis (AD) in Korea by using national statistics. Data on AD patients who received medical service at least once a year from 2003 through 2008 were collected from health insurance research team of National Health Insurance Corporation. Data of estimated populations during the same period were obtained from the Statistics Korea. In 2008, the prevalence of AD was 26.5% in aged 12-23 months and decreased substantially to 7.6% at age 6 yr, 3.4% at age 12 yr and to 2.4% at age 18 yr. In males, the prevalence was higher than females until 2 yr of age, while the opposite was shown in children aged 2 yr or older. In children aged less than 24 months, the prevalence of AD has increased from 19.8% to 23.8% between the years 2003 and 2008, while the prevalence showed no increase in the older age group. In conclusion, the prevalence of AD in 2008 peaked during infancy up to 26.5% and decreased thereafter. Our findings also suggest that increasing prevalence of AD in children less than 24 months might be responsible for the recent increase in the prevalence of AD in Korean children.

Mentions: The total prevalence of AD in Korean children and adults in 2008 was 2.2% (males, 2.1%; females, 2.4%). The prevalence of children and adolescents was 6.9% and the prevalence among females (7.2%) was higher than that of males (6.6%). The prevalence of AD aged less than 12 months was 21.1%. The highest prevalence of AD by age was 26.5% in the age group of 12-23 months. The cumulative prevalence of AD aged less than 24 months was 23.8%. Thereafter, the prevalence decreased substantially to 7.6% at age 6 yr, 3.4% at age 12 yr and to 2.4% at age 18 (Fig. 2).
