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.

Figure 1: The number of patients with AD by age and gender in Korea in 2008.

Mentions: The total number of AD patients in 2008 was 1,086,982 (516,785 [47.5%] males and 570,197 [52.5%] females). The number of female patients was more than male patients by 53,412 (4.9%). The number of patients aged less than 12 months was 94,253 (50,258 [53.3%] males and 43,995 [46.7%] females) and the number of male patients was more than female patients by 6,263 (6.6%). The number of patients aged 12-23 months was 117,988 (63,912 [54.2%] males and 54,076 [45.8%] females) and the number of male patients outnumbered female patients by 9,836 (8.3%). This age group accounted for the highest number of patients by age among all age groups. The number of patients at age 2, 3, 4 and 5 yr were 71,856, 51,879, 47,640, and 44,805, respectively and it decreased with age. The number of male patients at the age of 9 yr or younger was higher than for female patients, but by the age of 10 yr or older, female patients outnumbered male patients until middle age (Fig. 1). The number of patients aged 18 yr or younger was 764,569 and they accounted for 70.3% of the total number of patients with AD in 2008.
