Abstract: Objective To analyze the distribution of allergens and the influencing factors in patients with allergic rhinitis. Methods Employees of a science and technology park who underwent physical examinations at Beijing Aerospace General Hospital from January to December 2022 were selected for the study. Allergic rhinitis was diagnosed by questionnaire, physical examination, and allergen-specific IgE antibody testing. Descriptive methods were used to analyze the prevalence of allergic rhinitis and distribution characteristics of allergens. The influencing factors of allergic rhinitis were analyzed by univariate and multivariate analysis methods. Results A total of 11 541 employees were surveyed, among whom 1 849 were diagnosed with allergic rhinitis, with a prevalence rate of 16.02%. After allergen testing, there were 1 610 patients with inhaled allergens, for a positive rate of 87.07%; 484 patients with food allergens, for a positive rate of 26.18%. The top five inhaled allergens were dust mites （52.68%）, house dust （40.51%）, tree pollen （27.69%）, mugwort （13.90%）, and ragweed （11.52%）. The top five food allergens were cod/lobster/scallop （6.65%）, soybean （5.84%）, freshwater fish （4.98%）, crab （3.52%）, and shrimp （3.14%）. Among them, 736 patients were single allergens, accounting for 39.26%, and 1 113 patients had two allergens and over, accounting for 60.74%. Multivariate Logistic regression analysis showed that aged 18-29 years （OR=2.159）, aged 30-39 years （OR = 2.115）, BMI≥28.0 kg/m² （OR=1.717）, management position （OR= 1.358）, previous allergic history （OR=1.765）, parental allergic rhinitis （OR=1.444）, smoking or passive smoking （OR=1.513） were the influencing factors for allergic rhinitis. Conclusions The prevalence of allergic rhinitis among the occupational population in Beijing is high, and the main allergens are inhaled allergens. Age, BMI≥28 kg/m², employee in management position, previous allergic history, parental allergic rhinitis, and smoking or passive smoking were the influencing factors for allergic rhinitis.
