Geriatric Disease Prevention and Management Cohort: The KURE (Korea urban and rural elderly cohort) cohort
The elderly population in Korea has been increasing and is expected to enter a super-aged society at an unprecedented speed. This accelerated aging of the population may cast a big burden to both individuals and the society. The Korean Urban Rural Elderly (KURE) study was developed to evaluate the epidemiological characteristics and establish the prevention and management of major disorders of the elderly in Korea. In addition, we plan to build a community-based cohort and follow-up more than 3,500 elderly Koreans over 10 years, to create disease prevention and management strategies. This research involves the following: (1) recruiting 1,000 elderly citizens and registering them into the cohort, (2) collecting clinical examination data and baseline specimens from participants, (3) building a management system to utilize data and resources, (4) estsablishing the basic characteristics and prevalence of major diseases, beginning with the first year of the cohort study. We selected two communities within Korea, and recruited and examined subjects aged > 65 years. We recruited 3,518 study subjects from 2012 to 2015 through several methods: establishing a community base, conducting a random population survey (recruiting people on the street), and promoting volunteer participation through a poster based advertising campaign. In 2015, we recruited 576 elderly people > 65 years, conducted health examinations and surveys, and collected blood samples. As a baseline, 2,354 females accounted for 66.91% of all participants. The average age was 71.89 years, and the major group, representing 38.57% of the total, was aged between 70–74 years. The first and second follow-up health examinations will be performed every 4 years. Every 2 years after each health examination, an inter-assessment interview will be conducted to improve participant retention.
