ABSTRACT

OBJECTIVE@#To investigate the epidemiological characteristics of allergic rhinitis (AR) in urban and rural areas of Ningbo and Yongzhou.@*METHOD@#Fifteen fields in the two cities from October 2006 to June 2007 were randomly selected. Cases suspected with symptoms of AR by a self-administered and interview questionnaire were recommended to special examinations for confirmed diagnosis.@*RESULT@#1. A total of 9969 individuals from 3803 families were surveyed, of whom 303 suffered with AR. 2. The prevalence rate was 4.10% in Ningbo and 1.65% in Yongzhou (the sex-adjusted rate was 4.10% and 1.64% respectively, and the age-adjusted rate was 4.33% and 1.58%); the population of island inhabitants had the lowest prevalence rate of 0.73%. 3. The prevalence rate in patients with asthma and that with family genetic history was 8% and 12% respectively.@*CONCLUSION@#It demonstrates that the prevalence rate is higher in Ningbo than in Yongzhou, in urban than in rural and in adolescent than in other ages. Allergic rhinitis may be associated with asthma and related to genetic factors. Allergic rhinitis may be curable.
