Abstract: Objective: To annalyze the allergens distribution of patients with allergic rhinitis in Nanchong of Sichuan,and to provide basic information for the prevention,diagnosis,treatment and epidemiological studies.Method: Skin prick tests with 36 kinds of standard allergens were used to 3 621 patients with allergic rhinitis.All the patients were divided into different group on the basis of gender,age and history of allergic disease.Result: Allergen positive rate prick test was 73.73% in all patients.There were no significant differences in allergen positive rate between different gender(P>0.05).The top five allergens were all inhaled allergens,such as House dust mites,dust mites,rape pollen,the French phoenix tree pollen,and cat hair.In different age groups,allergen positive rate of group A,was different from group B,group C and group D respectively(P<0.05).Group B was different from group C and group D respectively(P<0.05).There were no significant differences between group C and group D(P>0.05).The groups with family history of allergic rhinitis,bronchial asthma and hypersensitivity pneumonitis respectively were different from its counterpart(P<0.05).And there were no significant differences between group with urticaria and group with contact dermatitis(P>0.05).Conclusion: The main allergens were inhaled allergens in Nanchong of Sichuan,such as dust mites,pollen,dust mites,rape French phoenix tree pollen,cat hair.Allergen positive rate has nothing to do with gender.Allergen positive rate was connected with age,history of allergic diseases(family history of allergic rhinitis andbronchial asthma and a history of hypersensitivity pneumonitis).
