Objective : This is a follow-up study of the surveys conducted in 1998 and 2008, to find change in the prevalence of sensitization to aeroallergen for children residing in the same communities.
Methods : For this purpose, skin prick tests for 16 types of aeroallergen were applied to 738 students from 2 elementary schools, 1 middle school and 2 high schools. The tests were performed for one month, in November, 2013. The data were analyzed by a statistical program, “SPSS ver. 18.0(SPSS Inc., Chicago, IL, USA).”
Results : Their age ranged from 7 to 18, with the average age of 13.1±3.26. The analysis of the 698 children effective for the skin prick tests showed the positive reaction to more than one among the 16 types of antigens in 59.2%. As for the sensitization rate, it showed increasing trends by their ageing (p=.001). The allergens of high sensitization rate were Dermatophagoides pteronyssinus (38.0%), Dermatophagoides farinae (33.8%), Japanese cedar (24.4%), Citrus red mite (23.8%), and Tyrophagus putrescentiae (14.7%). The sensitization rates in the 13 major aeroallergen showed a significantly increasing trend(p=.017): 37.6% (1998), 51.2% (2008), and 57.3% (2013). Aeroallergen with the significantly increasing trends in the sensitization rates included Japanese cedar, citrus red mites, cockroaches, animal hairs Ⅰ, and trees pollen mixture Ⅰ, etc. Conversely, ragweed showed a significantly decreasing trend.
Conclusion : It can be concluded that the aeroallergen sensitization rate of the children in Jeju Province has been on the increase, compared to that of the past. Therefore, continuous and regular study of variation in sensitization rate to aeroallergen is required, with the further efforts to reveal the unique allergens in Jeju Province
