Background: As elderly people increasing, prevalence of diabetes will increase but there was paucity of data on the epidemiology of diabetes in Korean elderly population. In this study (Southwest Seoul, SWS study) we investigated the change of prevalence of diabetes mellitus for two points in time (the years 1999 and 2002) and 3-year incidence of diabetes in elderly Korean population of southwest area of Seoul.
Methods: A sampling of 1,652 subjects in 1999 and 1,214 subjects in 2002 who are over 60 years old in southwest area of Seoul were investigated. All subjects underwent a 75 g oral glucose tolerance test (OGTT), biochemical study and anthropometric measurements. Among the 1,652 subjects in 1999, 350 subjects were followed up for 3 years and 294 subjects without diabetes at baseline examination participated in retrospective cohort study.
Results: Prevalence of diabetes in 1999 was 20.5% [previous diagnosed people (11.9%), newly diagnosed people (8.6%)] and in 2002 was 22.1% [previous diagnosed people (15.2%), newly diagnosed people (6.9%)]. Prevalence of impaired fasting glucose (IFG) or impaired glucose intolerance (IGT) was 22.8% in 1999 and 27.8% in 2002. In 350 subjects were followed up for 3 years, prevalence of diabetes was 16.0% in 1999 and increased to 23.4% in 2002 (p=0.014). In retrospective cohort study, the annual incidence rate of diabetes was 2.9% (age and sex adjusted rate 2.5%).
Conclusion: Prevalence of diabetes in elderly Korean population of southwest area of Seoul was 20.5% in 1999 and increased to 22.1% in 2002. Prevalence of IFG or IGT was 22.8% in 1999 and increased to 27.8% in 2002. This report supports that impaired glucose regulations and diabetes mellitus of elderly Korean population will increase in the future as aged Korean population increases.
