WHO Study on global AGEing and adult health (SAGE)
The WHO Multi-Country Studies unit coordinates the Study on global AGEing and adult health (SAGE) as part of an ongoing program of work to compile comprehensive longitudinal information on the health and well-being of adult populations and the ageing process. The core SAGE collects data on adults aged 50 years and older, including a smaller comparison sample of younger adults aged 18–49 years, from nationally representative samples in six countries: China, Ghana, India, Mexico, Russian Federation and South Africa. The map here also indicates, with dots, other country research collaborations and SAGE sub-studies.
SAGE is supported by the US National Institute on Aging, Division of Behavioral and Social Research.
