Purpose: We aimed to investigate the prevalence of atopic dermatitis (AD) and its associated risk factors in Korean children in 2022, and to compare to our findings with previous results to identify changes or trends over time.
Methods: A nationwide, cross-sectional study of randomly selected schoolchildren aged 6-7, 9-10, and 12-13 years, respectively, was completed. Information was obtained through the International Study of Asthma and Allergies in Childhood questionnaire, and comparisons between the current and prior surveys performed in 1995, 2000, and 2010 were conducted using a trend test.
