A Multicenter Study of Prevalence and Risk Factors for Allergic Rhinitis in Primary School Children in 5 Cities of Hubei Province, China

摘要

Background: Few data are available concerning the prevalence and risk factors for allergic rhinitis (AR) in school children in Hubei Province which is located in the central part of China. This study investigated the epidemiological features of AR among school children in Hubei Province. Methods: A cross-sectional questionnaire survey on AR in school children was carried out in 5 cities in Hubei Province by cluster sampling from June to September 2018. Questionnaires were filled out by children and their parents jointly. The diagnostic criteria of AR were according to the SFAR. Questions from the questionnaire were used to examine the pattern of AR. Logistic regression analysis was used to assess the risk factors for childhood allergies. Results: The total prevalence rate of AR was 16.16, with 24.31 (Wuhan), 4.34 (Xiangyang), 4.31 (Tianmen), 10.92 (Jingmen), and 11.42 (Huangshi), respectively. The prevalence of AR was positively correlated with gross domestic product per capita (p 8 h, siblings, and breastfeeding for >6 months reduced the risk significantly. Conclusion: We found the apparent geographic variation of children allergies in Hubei Province. Both genetic and environment factors had impacts on the prevalence of AR in school children. Public policies should specifically target at the local risk factors for different areas.
