Abstract
The purpose of this study was to investigate the prevalence rate of atopic dermatitis (AD) and indoor risk factors of AD in school-aged children living in Changwon, which is one of the largest industrial cities in Korean. Data were collected from 2,118 children in 12 elementary schools in Changwon city. A cross-sectional questionnaire based on the Korean Version of the ISAAC (International Study of Allergy and Asthma in Childhood) was employed to survey the <TEX>$1^{st}$</TEX> and <TEX>$4^{th}$</TEX> year elementary students from the 12 elementary schools in Changwon. The life time and last 12-month prevalence of itchy eczema were 20.6%; 70.5% in the elementary children. The life time and last 12-month prevalence of AD diagnosis were 28.8%; 12.6% in the elementary children. There was only one elementary school that was abnormal in the levels of particulate matters (PM), and <TEX>$Co_2$</TEX>. Multivariate logistic regression analysis revealed that risk factors for AD were BMI, the levels of PM, <TEX>$Co_2$</TEX>, CO, <TEX>$No_2$</TEX>, <TEX>$O_3$</TEX>, Ethylebenzene, and Xylene. This study could be used to manage possible risk factors that are related to the prevalence of AD and develop the strategies for prevention of AD.
