SAGE is part of the unit's Longitudinal Study Programme which is compiling longitudinal data on the health and well-being of adult populations, and the ageing process, through primary data collection and secondary data analysis.  INDEPTH SAGE Wave 1 (2006\/7) provides data on the health and well-being of adults in: Ghana, India and South Africa.\nObjectives: \nTo obtain reliable, valid and comparable health, health-related and well-being data over a range of key domains for adult and older adult populations in nationally representative samples \nTo examine patterns and dynamics of age-related changes in health and well-being using longitudinal follow-up of a cohort as they age, and to investigate socio-economic consequences of these health changes \nTo supplement and cross-validate self-reported measures of health and the anchoring vignette approach to improving comparability of self-reported measures, through measured performance tests for selected health domains \nTo collect health examination and biomarker data that improves reliability of morbidity and risk factor data and to objectively monitor the effect of interventions \n\nAdditional Objectives:\nTo generate large cohorts of older adult populations and comparison cohorts of younger populations for following-up intermediate outcomes, monitoring trends, examining transitions and life events, and addressing relationships between determinants and health, well-being and health-related outcomes \nTo develop a mechanism to link survey data to demographic surveillance site data \nTo build linkages with other national and multi-country ageing studies \nTo improve the methodologies to enhance the reliability and validity of health outcomes and determinants data \nTo provide a public-access information base to engage all stakeholders, including national policy makers and health systems planners, in planning and decision-making processes about the health and well-being of older adults \n\nMethods: \nINDEPTH SAGE's first full round of data collection included persons aged 50 years and older in the health and demographic surveillance sites. All persons aged 50+ years (for example, spouses and siblings) were invited to participate.  Standardized SAGE survey instruments were used in all countries consisting of  two main parts: 1) household questionnaire; 2) individual questionnaire. 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.\n\nContent\n\nHousehold questionnaire\n0000 Coversheet \n0100 Sampling Information \n0200 Geocoding and GPS Information \n0300 Recontact Information \n0350 Contact Record \n0400 Household Roster \n0450 Kish Tables and Household Consent \n0500 Housing \n0600 Household and Family Support Networks and Transfers \n0700 Assets and Household Income \n0800 Household Expenditures \n0900 Interviewer Observations \n\nIndividual questionnaire\n1000 Socio-Demographic Characteristics \n1500 Work History and Benefits \n2000 Health State Descriptions and Vignettes \n2500 Anthropometrics, Performance Tests and Biomarkers \n3000 Risk Factors and Preventive Health Behaviours \n4000 Chronic Conditions and Health Services Coverage \n5000 Health Care Utilization \n6000 Social Cohesion \n7000 Subjective Well-Being and Quality of Life (WHOQoL-8 and Day Reconstruction Method) \n8000 Impact of Caregiving \n9000 Interviewer Assessment","coll_dates":[{"start":"2007-03","end":"2007-07","cycle":""}],"nation":[{"name":"Ghana","abbreviation":"GHA"}],"geog_coverage":"Kassena-Nankana District of the Upper East region of Ghana.","analysis_unit":"households and individuals","universe":"Navrongo Health and Demographic Surveillance Site fifty plus population","data_kind":"Sample survey data [ssd]","notes":"The scope of the INDEPTH Study on Global Ageing and Adult Health includes:\nHOUSEHOLD: household characteristics, housing, household and family support, assets and household income, household expenditure.\nINDIVIDUAL: socio demographic characteristics, work history, health state, anthropometrics, performance tests and biomarkers, risk factors, chronic conditions and health service coverage, health care utilisation, social cohesion, subjective well-being and quality of life, caregiving."},"method":{"data_collection":{"data_collectors":[{"name":"Navrongo Health Research Centre","abbreviation":"NHRC","affiliation":"Ghana Health Service"}],"sampling_procedure":"Single random sample of individuals 50+ years.

Training of interviewers took place from 12 February to 9 March, 2007. A pre-test of the survey instruments was included as part of the training. At the end of the training, thirteen individuals were selected to conduct the data collection. Eleven persons conducted the face-to-face interviews while two persons performed the measured tests. The interview team visited selected respondents in their houses, explained the study to them and invited them to participate in the survey. Written informed consent was obtained before individuals were interviewed in their local language. The measurement team visited respondents a few days after the interview to administer various tests and take measurements. Data collection took place from 12 March to 5 July, 2007. Two supervisors visited interviewers daily to observe the fieldwork and address any problems interviewers experienced.","act_min":"A research assistant reviewed all completed questionnaires for consistency, missed items and other errors.
