Abstract:ObjectiveTo investigate the main allergens in children with allergic rhinitis(AR) in Kunming.MethodsThirteen kinds of common allergens in Kunming were used for performing skin prick test(SPT) in 567 children suffering from suspected AR. All the children were divided into 9 age groups and 2 gender groups. And the distributions of different allergens in all the groups were analyzed.Results①The positive rates of SPT for Dermatophagoides farinae (Der f), Dermatophagoides pteronyssinus (Der p), Mugwort, Platanus in female group were significantly higher than those in male group (t=2.701, P=0.012). ②The differences of allergens distributions among different age groups were statistically insignificant（P>0.05）. ③The total positive rate was 93.5%, including 2.1% with single positive allergen and 91.4% with multiple allergens. As for Der f and Der p, the rates with single positive allergen and dual positive allergens were 5.46% and 85.4% respectively. ④ The average numbers of positive allergens were increasing with increasing age (F=8.738, P=0.012), while the differences between different genders were insignificant in each age group (F=1.873, P=0.400).ConclusionsDust mites, Mugwort and Platanus are identified as the most common allergens among pediatric patients with AR in Kunming. The average numbers of positive allergens are increased with increased age.
