Prevalence of Atopic Dermatitis in Korean Children Based on Data From the 2008-2011 Korean National Health and Nutrition Examination Survey.

The mean age of the AD group was 9.45, which was significantly younger than that of the non-AD group, which was consistent with previous studies showing a decreasing trend of AD with age. 17 , 18 Our results also showed that there was no difference in the prevalence of AD between females and males, which was different from a previous report showing a female preponderance for AD, with an overall female/male ratio of 1.3:1.0. 19 Several previous reports have shown that there is no significant relationship between AD and demographic data, such as gender, BMI, and height. 13 , 20 , 21 , 22 Likewise, in our study, BMI, height, weight, and waist circumference were not associated with AD in Korean children after adjusting for age.
