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.

Figure 3: The number of patients, estimated population and prevalence of AD in children aged less than 24 months from 2003 through 2008.

Mentions: The prevalence of AD in Korean children and adolescents aged under 18 yr slightly decreased from 7.2% in 2003 to 6.9% in 2008. After the patients were divided into 3 different age groups (less than 24 months, 2-5 yr, 6-18 yr), we analyzed the prevalence change in each age group. The estimated populations aged less than 24 months were 1,025,850 in 2003, 973,142 in 2004, 932,113 in 2005, 893,334 in 2006, 888,667 in 2007 and 892,534 in 2008. The number of patients was 202,846, 206,568, 197,427, 186,187, 204,083, and 212,241, respectively, from 2003 through 2008. When comparing years 2003 and 2008, the estimated population aged less than 24 months decreased by 133,316 (13.0%), but the AD prevalence of this age group increased significantly from 19.8% to 23.8% (Fig. 3). In contrast, the prevalence was slightly decreased from 12.3% to 11.7% in children aged 2-5 yr (Fig. 4), and also slightly decreased from 4.2% to 4.0% in children and adolescents aged 6-18 yr old (Fig. 5).
