@entity1 @entity7025
There have been a few studies reporting the epidemiology of @entity7025 in Korea. Previous studies revealed relatively high prevalence and incidence of @entity7025 in Korea and Japan. This study was designed to provide the latest epidemiologic information of @entity7025 in Korea. We analyzed a database comprising of 50 million @entity1 covered in Korea by the National Health Insurance Service to calculate the prevalence. The incidence was estimated by eliminating the duplicated records of previous 3 years. We summarized the prevalence and incidence according to age, sex, and local distribution. In addition, the chronological changes were demonstrated with direct standardization using the 2010 population structure information. The standardized prevalence was 6.5 per 100000 @entity1 in 2005, which was increased to 18.1 in 2013. In the same period, standardized incidence was increased from 2.7 to 4.3 per 100000 @entity1 . The prevalence for @entity1 was 4.9 and 8.3 for @entity1 in 2005. In 2013, the prevalence had increased for @entity1 and @entity1 to 13.8 and 25.3, respectively. The incidence for @entity1 and @entity1 was 2.2 and 3.2, respectively, in 2005. It had increased to 3.5 and 5.7, respectively. The mean age of @entity1 was 33.5 in 2005 and increased to 42.5 in 2013. The peak prevalent age group had shifted slightly to the older age groups, with chronologically consistent female predominance. The prevalence was highest in Jeollabuk province and lowest in Ulsan city.
