Objective : This study is to discover the trends and changes related to aeroallergen as they relate to the residential environment of school children in Jeju Province, using a cross-sectional study with a span of 6 years,
from 2010 to 2016.
Methods : The same study method employed 6 years ago was applied to the students from 13 elementary, middle and high schools in the Jeju Province. The skin prick test was performed for 18 types of aeroallergen under the approval of Institutional Review Board (IRB) and the consent of the subjects and their parents. The subjects for the effective final analysis were 1,549 in 2010 and 1,087 in 2016.
Results : The results indicate that the sensitization rates of aeroallergen were on a sharp increase: from 43.7% in 2010 to 51.8% in 2016. As for the sensitization rate, the risk degree for Japanese cedars showed 2.97 times in 2016, compared to 2.61 times in 2010. That for Alternaria showed 2.12 times in 2016 to 3.45 times in 2010. The allergens of the high sensitization rate were listed in the order of D. pteronyssinus, D. farinae, Japanese cedar, Timothy grass, and Alternaria.
Conclusions : The residential environment makes meaningful significances in the sensitization rates of aeroallergen,
showing high increase in sensitization rates. This suggests that allergic disease prevention and care programs should be implemented in order to cope with each residential environment.
