AB  - Background: We previously reported a high prevalence of allergic rhinitis in young adults in Western Sweden in 2008.Aims: The aims were to analyse the prevalence of allergic rhinitis among young adults in Western Sweden in 2016 compared with 2008 and to analyse the risk factors for allergic rhinitis in 2016.Methods: A postal questionnaire was mailed to 30,000 randomly selected subjects aged 16-75 years in Western Sweden in 2008 and to 50,000 in 2016. The analyses presented here were based on responders aged 16-25 in the two cohorts: 2008, n=2,143, 56.6% women, mean age 21.0 years and 2016, n=2,484, 56.9% women, mean age 21.2 years.Results: The prevalence of allergic rhinitis increased from 28% in 2008 to 32% in 2016, p=0.003. The increase from 2008 to 2016 was significant among men, 27.0% vs 33.0%, p=0.003, but did not reach significance in women, 28.8% vs 31.2%, p=0.186.In 2008 the prevalence of allergic rhinitis in women was 28.8% compared with 27.0% in men, p=0.362, while in 2016 the prevalence was 31.2% in women and 33.0% in men, p=0.362.In a multivariate analysis the risk of allergic rhinitis in young adults in 2016 was increased by a family history of allergy, adjusted OR 6.5, 95% CI 5.1-8.2, and a family history of both asthma and allergy, aOR 6.3, 4.9-8.3. Women had a reduced risk of allergic rhinitis compared with men, aOR 0.8, 0.6-0.9.Conclusion: The prevalence of allergic rhinitis increased from 2008 to 2016 in young adults aged 16-25 in Western Sweden. The increase was seen mainly among men. A family history of allergy increased, while female gender reduced the risk of allergic rhinitis in the cohort of 2016.FootnotesCite this article as: European Respiratory Journal 2018 52: Suppl. 62, PA3906.This is an ERS International Congress abstract.
