• Purpose The proportion of elderly people aged ≥ 65 years is increasing worldwide. Although the reported prevalence of sinonasal disease can vary according to the diagnostic methods used, differences in allergic rhinitis prevalence in the elderly according to diagnostic method have not been reported. We thus aimed to evaluate allergic rhinitis prevalence in the elderly according to diagnostic criteria obtained from questionnaires, physician diagnoses, and allergy tests. Methods We compared the allergic rhinitis prevalence in the elderly aged ≥ 65 years with adults aged 19–64 years, using data from the Korean National Health and Nutrition Examination Survey 2008–2012. Total serum IgE and IgE levels specific to allergens of Dermatophagoides farina , cockroach, and dog dander were examined, and factors affecting specific IgE levels were investigated. Results Allergic rhinitis prevalence according to the questionnaire responses, physician diagnoses, and allergy test results was 35.02%, 14.89%, and 17.56%, respectively. The prevalence based on all diagnostic methods assessed was significantly lower in the elderly than in the general adult group ( p  < 0.001). Rhinorrhea incidence was significantly increased in the elderly ( p  = 0.018). Sensitization to Dermatophagoides farina was significantly decreased in the elderly ( p  = 0.006) and did not correlate with socioeconomic status and/or general health factors. Conclusions The elderly population has a distinct clinical presentation, including a low prevalence of allergic rhinitis, and an increased incidence of rhinorrhea symptoms, compared with the general adult population. The management of allergic rhinitis in elderly patients may therefore require a different therapeutic approach to improve rhinorrhea rather than nasal obstruction.
