Harmonization Study Design
A harmonised dataset can be created for each wave and population according to the ATHLOS DataSchema and the harmonisation codes located on Github:
DataSchema: https://athlos.pssjd.org/ws/file-dl/network/athlos/DataSchema_ATHLOS.xlsx
Harmonisation codes: https://github.com/athlosproject/athlos-project.github.io/tree/master/KLOSA
Please contact us if anyone is interested in harmonising KLOSA study data via the ATHLOS DataSchema.
KLOSA population
The population is composed of middle-aged and senior citizens over the age of 45 in all regions of Korea except for Jeju Island in 2005. Computer Assisted Personal Interviewing (CAPI) was adopted as its interview method.
