World Health Organization Study on Global Aging and Adult Health (SAGE)

Thursday, August 26, 2004 to Friday, August 27, 2004

The World Health Organization’s Multi-Country Studies Team developed the Study on Global Ageing and Adult Health (SAGE) to collect a range of valid, reliable, and comparable information on the health and well-being of older persons in low and middle income countries that could be used by national health information systems to fill critical information gaps. Data modules included self-reported health assessments linked to anchoring vignettes and traditional measures of functioning combined with measured performance testing in various health domains. The first technical consultation sought expert advice on the content of the survey instrument, the design and implementation of the longitudinal follow-up, and validation methods to improve comparability. The second advisory group meeting recommended final content and study design.
