WHS/SAGE Wave 0 (2002-04)

Survey instruments are available here . Data are in the public domain for Ghana, China, India, Mexico, Russian Federation, South Africa and 64 other countries participating in the WHS and are available through WHO at no cost. Wave 0 meta- and micro-data are available on request at no cost. Complete and send a Users Agreement (see top of page to download form) via email with the subject line, "WHS/SAGE Wave 0 - Users Agreement"). A password will be forwarded to legitimate researchers to access the data via the WHO World Health Survey results.

SAGE Pilot study (2005)

The survey instrument for SAGE was based on surveys created as part of the World Health Organization's World Health Survey programme , comparisons to 16 other cross-sectional or longitudinal studies on ageing (including the US Health and Retirement Survey and the English Longitudinal Study on Ageing), recommendations from an expert Advisory Group, and cognitive testing of a draft instrument in two countries (South Africa and Viet Nam in 2004). The resulting survey instrument was piloted in Ghana, India and Tanzania in April through July 2005. The individual questionnaire was implemented in five rotations to decrease respondent and interviewer burden - with the Sections 2000 and 7000 differing (see box).

The micro-data are in the public domain and available through WHO at no cost on request. Complete and send a Users Agreement (available at top of page) via email with subject line, "SAGE Pilot - Users Agreement"). A password will be forwarded to legitimate researchers to access the data.

SAGE Wave 1 (2007-09)

A FIRST RELEASE of partially cleaned, unweighted micro-data, SAGE 1.0.0, are now in the public domain and available through WHO at no cost on request for Ghana, India, Russian Federation and South Africa. A first release for China and Mexico data will be ready in early 2010. Requests should include a completed Users Agreement form (see top of page to download form) and send via email. with subject line, "SAGE Wave 1 first release - Users Agreement"). A password and web link will be forwarded to legitimate researchers to access the data. Users are requested to use the following acknowledgement: “This paper uses data from WHO SAGE version 1.0.0. SAGE was supported by the US National Institute on Aging, Division of Behavioral and Social Research through an Inter-Agency Agreement.” SAGE version 1.1.0, cleaned and weighted, will be available after April 2010.

The SAGE survey instruments assessed health status and health systems from a household and individual perspective. SAGE also evaluated perceptions of well-being and more objective measures of health, including measured performance tests: 4m timed walk; spirometry; cognitive battery (verbal fluency, immediate and delayed recall, digit span forward and backward); near and distance vision; and, grip strength; and biomarkers: blood pressure and pulse rate; height and weight; hip and waist circumference; and, blood spot from fingerprick.

Standardized SAGE survey instruments were used in all countries consisting of five main parts: 1) household questionnaire; 2) individual questionnaire; 3) proxy questionnaire; 4) verbal autopsy questionnaire; and, 5) appendices including showcards. A VAQ was completed for deaths in the household over the last 24 months. 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.

OTHER KEY ISSUES FOR SAGE

• Adapting the instruments to address local concerns / addressing methodological issues through focused studies, for example: caregiving burden in sub-Saharan Africa; nutritional assessment in older adults; culture-fair cognitive assessments;
• Addressing problems of accuracy in age-reporting;
• Planning effective follow-up strategies – taking into account migration and attrition issues;
• Improving cross-national comparability of data through additional validation studies of survey methodologies;
• Testing and validating new, novel methods – such as the Day Reconstruction Method as part of the Subjective well-being and quality of life module; and,
• Developing linkages with national and local data collection efforts (for example, HRS, ELSA, SHARE, INDEPTH, CHARLs, LASI, SABE, NFHS, ALSWH and others).
