Abstract
Purpose
Allergic rhinitis (AR) is one of the most common childhood diseases in Korea. In this study, we aimed to investigate the prevalence and allergens of childhood AR in Gwangju.
Methods
From April 2013 to September 2013 in Gwangju, skin prick test and questionnaire survey were performed targeting 2,330 children in total (350 kindergartners, 930 elementary school students, 589 middle school students, and 461 high school students).
Results
The overall prevalence of AR was 23.5% (female 21.3%, male 26.1%). According to age groups, prevalence of AR was 14.9% (female 10.7%, male 19.8%) in kindergartners, 24.5% (female 18.8%, male 29.4%) in elementary school students, 23.3% (female 18.1%, male 27.6%) in middle school students, 26.2% (female 27.7%, male 23.2%) in high school students. The most common allergen was Dermatophagoides pteronyssinus (79.7%), followed by Dermatophagoides farina (72.2%), birch (14.0%), alder (12.0%), Japanese hop (9.2%), Alternaria (8.9%), cat fur (7.2%), Japanese cedar (6.9%), ryegrass (6.6%), willow (6.0%), pine (5.4%), oak (4.9%), mugwort (4.3%), orchard grass (4.0%), sheep fescue (3.7%), fat hen (3.4%), ragweed (3.4%), and maple (3.4%).
Figures and Tables
