Investigation on risk factors of adult allergic rhinitis in China

Abstract OBJECTIVE: To investigate the risk factors associated with allergic rhinitis in adults. METHODS: Using the 1:1 matching principle, 1096 cases of allergic rhinitis patients aged 18-65 years were selected as the observation group, and another group of healthy medical checkups were selected as the control group, and the data related to allergic rhinitis were collected by allergen testing and questionnaire survey, and univariate and multifactorial analyses were performed respectively. RESULTS: The univariate analysis showed that allergic rhinitis may be related to temperature changes, dryness and humidity, air pressure, wind speed, seasonal changes and exposure to allergens such as dust mites and house dust mites. After allergen testing of all patients in the observation group, it was found that dust mite and house dust mite were the highest percentage of allergens, accounting for 40.51%, indicating that environmental factors play a decisive role in allergic rhinitis. Multi-factor analysis showed that exposure to dust mites, house dust mites, Penicillium punctatum, Streptomyces crossatus and Aspergillus fumigatus were independent risk factors for allergic rhinitis when it was humid, when it was cold, when it was windy and when the air pressure was low. CONCLUSION: The epidemiological status of allergic rhinitis in adults in China was initially understood, and the main allergens were house dust mite and dust mite, which provided scientific epidemiological information for the standardized prevention and treatment of allergic rhinitis in this region.
