Objectives: This study tries to reveal the aeroallergen sensitization rates and their connection on allergic diseases. The people in this study were the inhabitants on Udo Isle, one of the small isles near Jeju Island. Methods: The survey was performed from June to July, 2012. The target was the inhabitants residing on Udo Isle and their age ranged from 5 to 69. The questionnaire survey was applied, using International Study of Asthma and Allergies in Childhood(ISAAC). Skin prick tests were also conducted, using 16 types of aeroallergens. For the questionnaire survey, the interviewers visited every family. With regard to children(5-19 years old), their parents` responses were collected. For adults, their self reports and face-to-face interviews were enrolled This analysis included 176 effective responses(79.6%) among the 221 examinees who consented the questionnaire survey and skin prick tests. Results: With regard to asthma, the prevalence of “wheeze, last 12 months” was 7.4%, 21.3% for “allergic rhinitis, last 12 months”, and 12.6% for “itchy eczema, last 12 months”. The sensitization rate of aeroallergens was 22.2%. Children`s sensitization rate(38.1%) was higher than that of adults(17.2%). The aeroallergens representing higher sensitization rate was listed as the following order: D. pteronyssinus, D. farinae, citrus red mite, and mould mixtureⅠ. This survey revealed that house dust mite such as D. pteronyssinus or D. farinae was the one of the major allergens for allergic rhinitis. Conclusion: Like the inhabitants of many other regions, the residents on the Udo Isle were highly sensitized to house dust mite, with the major connection on allergic rhinitis. Compared to the Jeju Island, the sensitization rate of Citrus red mite and Japanese cedar was very low. The further systematic study regarding time trends in the prevalence and cause of allergic disease in relation to the environmental changes, might be needed.
