Objective To investigate the common inhalant allergens causing allergic rhinitis in underage patients, and provide references for clinical prevention of allergic rhinitis. Methods Underage patients with allergic rhinitis admitted to our hospital between January 2010 and June 2013 were screened and skin prick test (SPT) was applied to investigate the response intensity to 22 kinds of common inhalant allergens and analyze the correlation of the positive rates and grades of allergens with age and sex. Results A total of 402 patients were included, and 77.6% (312/402) of them reported positive reaction of SPT; and the top five allergens were dust mites (242/402, 60.2%), house dust (235/402, 58.5%), housefly (142/402, 35.3%), spring pollen Ⅲ (133/402, 33.1%) and mulberry silk (121/402, 30.1%), respectively. Compared with patients whose age was younger than 5 years, both the positive rates and grades of SPT were significantly higher in patients above 5 years old. Additionally, the higher positive rates and grades of SPT were also observed much more in male patients than female patients. Conclusion The most common inhalant allergens causing allergic rhinitis in underage patients are dust mites and house dust. And the SPT response intensity of inhalant allergens can be affected by age and gender.
