By mobile APP the questionnaires were distributed and filled online by parents and children together. By the Score for Allergic rhinitis, AR was diagnosed. For the assessment of the risk factors for AR, the Logistic regression analysis was performed.
5550 valid questionnaires were returned for evaluation. The prevalence of AR among 6-12-year-old children in the urban area of Wuhan was 28.6%. Multivariate analysis revealed that male, family history of atopy, previous food allergies, air purifier, exposure to dust, maternal exposure to smoke during pregnancy, living in towns or metropolis before 2 years old, frequent application of antibiotics are risk factors for AR, while the daily outdoor time for more than 1 hour and breastfeeding for more than 6 months reduced the risk significantly.
