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.
我们试图通过使用国家统计数据来调查韩国特应性皮炎（AD）的患病率。从 2003 年至 2008 年，从国家健康保险公司健康保险研究小组收集了至少每年接受一次医疗服务的 AD 患者的数据。同期估计人口数据来自韩国统计局。2008 年，12-23 个月龄儿童 AD 的患病率为 26.5%，降至 6 岁时的 7.6%、12 岁时的 3.4%和 18 岁时的 2.4%。在男性中，AD 的患病率一直高于女性，直到 2 岁，而在 2 岁以上的儿童中则相反。在年龄小于 24 个月的儿童中，AD 的患病率在 2003 年至 2008 年间从 19.8%增加到 23.8%，而在年龄较大的组中则没有增加。总之，2008 年 AD 的患病率在婴儿期达到峰值，达 26.5%，此后逐渐下降。我们的研究结果还表明，24 个月以下儿童 AD 患病率的增加可能是导致韩国儿童 AD 患病率近期增加的原因。
