Abstract: The Study of Global Ageing and Adult Health (SAGE) is a longitudinal study launched by the World Health Organization (WHO). It covers six countries (China, Ghana, India, Mexico, Russia and South Africa) and builds upon prior data from the World Health Survey (WHS) 2002-2004. SAGE is designed to follow cohorts of individuals over age 50 to examine changes in health status and well-being and determine predictors of change, such as economic activity, transitions in life situations and social cohesion. In 2005 a SAGE questionnaire was piloted in over 1500 respondents in three countries, Ghana, India and Tanzania. It collected data about income, expenditures and transfers; work history; self-reported assessments of health linked to anchoring vignettes; risk factors; health care utilization; measured performance tests on a range of different domains of health; well-being, happiness and quality of life; and biomarkers. A full followup was conducted between 2007 and 2009 in the six base wave countries. This wave 1 sampling design was to obtain a nationally representative cohort of persons aged 50 years and older, with a smaller cohort of persons aged 18 to 49 for comparison purposes. The target sample size was 5000 households with at least one person aged 50+ years and 1000 households with an 18 to 49 year old respondent. In the older households, all persons aged 50+ years (for example, spouses and siblings) were invited to participate. Proxy respondents were identified for respondents who were unable to respond for themselves (using the IQ Code).
