我们研究了韩国学校中与过敏原污染有关的呼吸道症状、哮喘和特应性过敏的报告，并与之前在8所小学进行的瑞典研究的数据进行了比较。韩国学生（n = 2365）在12所小学，首先完成了问卷调查。然后从34间教室收集空气和沉降灰尘，用ELISA法分析过敏原。在这两个国家，男孩报告的症状更多。喘鸣的患病率相似，而韩国学生的日间[比值比（OR）= 14.0，95%置信区间（CI）= 9.0-21.9]和夜间呼吸困难（OR = 3.1，95% CI = 1.5-6.4）要高得多。在韩国学校，狗过敏原（Can f 1）是最常见的，其次是螨过敏原（Der f 1），而猫（Fel d 1），狗和马过敏原（Equ cx）在瑞典丰富。此外，大多数韩国学校的二氧化碳水平很高（907-4113 ppm）。灰尘和空气样本中的过敏原水平与教室里养宠物的人数有关。总之，韩国学校的过敏原污染可能是一个重要的公共问题。
We studied reports on respiratory symptoms, asthma and atopic sensitisation in relation to allergen contamination in Korean schools and compared with data from a previous Swedish study performed in eight primary schools. Korean pupils (n = 2365) in 12 primary schools first completed a questionnaire. Then airborne and settled dust were collected from 34 classrooms and analyzed for allergens by ELISA. In both countries, boys reported more symptoms. The prevalence of wheeze was similar, while daytime [odds ratio (OR) = 14.0, 95% confidence interval (CI) = 9.0-21.9] and nocturnal breathlessness (OR = 3.1, 95% CI = 1.5-6.4) were much higher among Korean students. In Korean schools, dog allergen (Can f 1) was the most common followed by mite allergen (Der f 1), while cat (Fel d 1), dog, and horse allergen (Equ cx) were abundant in Sweden. Moreover, CO2 levels were high in most Korean schools (range 907-4113 ppm). There was an association between allergen levels in dust and air samples, and number of pet-keepers in the classrooms. In conclusion, allergen contamination in Korean schools may be an important public issue.
