Study on Global Ageing and Adult Health

SAGE baseline data (Wave 0, 2002–04) was collected as part of WHO's World Health Survey (WHS).

A second round of data collection (Wave 1, 2007–10) is completed, expanding the sample sizes in each participating country (China, Ghana, India, Mexico, the Russian Federation and South Africa).

Weighted data for China, Ghana, India, Mexico, Russian Federation and South Africa are in the public domain (see Study on global AGEing and Adult Health).

SAGE's first full round of data collection included both follow-up and new respondents in four participating countries.

The procedures for including country-specific adaptations to the standardized questionnaire and translations into local languages from English follow those developed by and used for the World Health Survey.

(NIA grant R21AG034263) SAGE-like surveys have been conducted as the World Health Survey Plus (WHS+) in the Gulf Cooperation Council countries, as a short version of SAGE in eight demographic surveillance fieldsites INDEPTH; as a full SAGE in three INDEPTH fieldsites; and, as COURAGE in Europe in three European countries.

A goal of this sub-study is to monitor change in cardiovascular outcomes associated with salt reduction, including blood pressure, and examine tobacco consumption levels and patterns.

These data include the SAGE health state descriptions, WHO Disability Assessment Schedule version 2 (WHODAS-II) and the WHO Quality of Life (WHOQoL) 8-item version as measures of health and subjective well-being, linked to selected sociodemographic data from the demographic surveillance fieldsites in eight countries (Bangladesh, Ghana, India, Indonesia, Kenya, South Africa, Tanzania and Viet Nam).

SAGE and SAGE sub-studies are supported by the World Health Organization and the Division of Behavioral and Social Research at the National Institute on Aging (NIA BSR), US National Institutes of Health, through Interagency Agreements (OGHA 04034785; YA1323-08-CN-0020; Y1-AG-1005-01) with WHO and a Research Project Grant R01 AG034479.

NIA BSR has facilitated forums for in-depth discussions about study content, design and implementation.

The NIA BSR has been instrumental in promoting linkages between longitudinal studies on ageing and adult health around the world.

Governments in three countries, China, Mexico and South Africa, provided financial support for SAGE Wave 1.
