Korean Longitudinal Study of Aging (KLoSA)
KLoSA was designed to provide basic data on population ageing in Korea. At baseline, the KLoSA cohort comprised middle- to old individuals aged 45 years or older (born in 1961 or earlier) across South Korea (not including Jeju Island). Participants were selected randomly using a multistage, stratified probability sampling design to create a nationally representative sample of community-dwelling Koreans 45 years of age and older. The exact sample size at baseline was 6,171 households and 10,254 individuals. In 2014, KLoSA recruited a new cohort of 1,000 Korean Baby Boomers (born between 1962 and 1963) in the fifth baseline survey and has continued to keep track of this new cohort since its addition.
