Abstract
Background: Although the prevalence of chronic allergic diseases has increased worldwide for several decades, some developed countries recently have shown a slowdown in the incidence of allergic diseases. The aim of this study was to evaluate the recent trends in the prevalence of asthma and other chronic allergic diseases in Korea.
Methods: From a database of approximately 50 million beneficiaries in the Korean National Health Insurance (NHI) and Health Insurance Review and Assessment Service (HIRA), data-sets of patients with diagnoses of atopic dermatitis, allergic rhinitis, and asthma were extracted. We analyzed the annual prevalence of asthma, allergic rhinitis, and atopic dermatitis in Korea from 2009 to 2013.
Results: The prevalence per 1,000 people of atopic dermatitis, allergic rhinitis, and asthma in 2013 was 20.3, 127.3, and 39.4, respectively. When divided into 10-year age groups, the prevalence of all three diseases was highest in the age group under 10. The prevalence of atopic dermatitis and allergic rhinitis had a decreasing pattern with older age, but for asthma, it showed an increasing pattern for the age group 30-39 and another peak for the age group 70-79. During the study period from 2009 to 2013, the prevalence of allergic rhinitis steadily increased in all age groups including the fastest growth in the age group under 10 with an annual average growth rate of 3.2%. In contrast, the prevalence of asthma and atopic dermatitis did not increase during the same period and instead showed a decrease in the age group under 10.
Conclusion: We analyzed the prevalence of chronic allergic diseases in Korea based on nationwide health insurance data. While the prevalence of allergic rhinitis increased for the past 5 years, the prevalence of asthma and atopic dermatitis did not show an increase. These results suggest that the prevalence of chronic allergic diseases in Korea might have plateaued currently.
