The Korean Longitudinal Study of Ageing

KLOSA logo
Initiatives -
The purpose of KLoSA is to create the basic data needed to devise and implement effective social, economic policies to address the trends that emerge in the process of population ageing. The data will help identify and observe different dimensions of an aged society, build datasets that enable studies in different fields, and generate data comparable with similar panel studies in other countries (eg. U.S., Europe) that can provide the basis for policy-making and academic studies. Aims are: 1) to estimate the prevalence, incidence and progression of common geriatric diseases; 2) to determine the risk factors for common geriatric diseases and to develop preventive strategies by managing potentially modifiable determinants; 3) to investigate the influence of common geriatric diseases on the quality of life and general health status; 4) to evaluate the levels of health and functional status of Korean elderly persons.

Follow Up
KLoSA conducts two types of surveys, baseline and special. Baseline survey is conducted every even-numbered year starting from 2006 and uses the same survey categories. The surveys thereafter will also be held in the second half of the year. Special survey takes place in every odd-numbered year under special topics not included in baseline survey.
