The objective of this study was to estimate the association between ambient ozone levels and hospitalization for asthma/atopic dermatitis among children younger than 15 years old living in Seoul and Ulsan, Korea, in the years 2004-2005. Estimated relative risks of hospital admissions associated with an interquartile range (IQR) increase in ozone concentration were calculated using a generalized additive Poisson model. For childhood asthma, the effect of an ozone increase on the relative risks in Ulsan [1.21 (95% CI, 1.10-1.34)] was higher than that in Seoul [1.05 (95% CI, 0.99-1.11)]. The relative risks for childhood atopic dermatitis were also found to be higher in Ulsan [1.38 (95% CI, 0.80-2.36)] than in Seoul [1.28 (95% CI, 1.04-1.58)]. These results support previously reported findings and also indicate that ozone concentrations at levels below the standards in the Republic of Korea can be correlated with asthma hospital admissions in children.
本研究旨在估计 2004-2005 年期间，居住在韩国首尔和蔚山的 15 岁以下儿童因环境臭氧水平而住院治疗哮喘/特应性皮炎的相关性。使用广义加性泊松模型计算与臭氧浓度四分位距（IQR）增加相关的住院相对风险。对于儿童哮喘，臭氧增加对蔚山的相对风险的影响[1.21（95%CI，1.10-1.34）]高于首尔[1.05（95%CI，0.99-1.11）]。还发现儿童特应性皮炎的相对风险在蔚山[1.38（95%CI，0.80-2.36）]也高于首尔[1.28（95%CI，1.04-1.58）]。这些结果支持了之前的报告结果，并表明韩国标准以下的臭氧浓度与儿童哮喘住院治疗相关。
