National Survey of the Japanese Elderly: Wave 3, 1993

Investigators: Institute of Gerontology Tokyo Metropolitan Institute of Gerontology

The National Survey of the Japanese Elderly (NSJE) is a longitudinal study conducted in Japan by the Institute of Gerontology at the University of Michigan (IoG) and the Tokyo Metropolitan Institute of Gerontology (TMIG). The first wave of the study was conducted in 1987 and collected data on a nationally representative sample of non- institutionalized Japanese aged 60 years and older. Subsequent Waves 2, 3, and 4 have followed in 1990, 1993, 1996 respectively. The original Wave 1 survey was designed to create a panel dataset for use in cross-cultural analyses of aging in Japan and the United States. The subsequent waves were created to match Wave 1 as closely as possible, while also allowing for growth in specific areas of interest. In addition, the surveys were designed to be partially comparable in content with Americans' Changing Lives: Waves 1, 2, 3, and 4, 1986, 1989, 1994, and 1996 and the National Health Interview Survey, 1984: Supplement on Aging. The survey has nine sections: demographics (age, gender, marital status, education, employment), social integration (interpersonal contacts, social supports), health status (limitations on daily life and activities, health conditions, level of physical activity), subjective well-being and mental health status (life satisfaction, morale), psychological indicators (life events, locus of control, self-esteem), financial situation (financial status), memory (measures of cognitive functioning), and interviewer observations (assessments of respondents).

Second Longitudinal Study of Aging: Baseline (Second Supplement on Aging, 1994-1996)

Investigators: National Center for Health Statistics

The Second Longitudinal Study of Aging (LSOA II) is a collaborative effort of the National Center for Health Statistics (NCHS) and the National Institute on Aging (NIA). Conducted ten years after the original LSOA, it is a prospective study with a nationally representative sample comprised of 9,447 civilian non-institutionalized persons 70 years of age and over in 1995. The specific aims of the study include: To provide a replication of the first SOA in order to determine whether there have been changes in the disability and impairment process among older persons between the 1980's and 1990's; To provide information on the sequence and consequences of health events, including utilization of health care and services for assisted community living, on the physiological consequences of disability such as pain and fatigue, on social consequences such as changes in social activities, living arrangements, social support, and use of community services, and on the deployment of assisted living strategies and accessibility of technological and environmental adaptations; To provide information on the causes and correlates of changes in health and functioning of older Americans, including social and demographic characteristics, preexisting and emerging physical illnesses, cognitive and emotional status, and social and environmental support; and To provide information on individual health risks and behaviors in the elderly including alcohol and cigarette use, use of hormone replacement therapy, receipt of important health screenings such as mammography and prostate exams, body mass and weight loss, physical activity, and diet and nutrition. The Second Supplement on Aging (SOA II), conducted as a supplement to the 1994 National Health Institute Survey (NHIS), served as the baseline for the LSOA II. Follow-up interviews were conducted in 1997–98 (Wave 2) and 1999–2000 (Wave 3). The baseline interview was administered face-to-face in the home by U.S. Census Bureau interviewers. The Wave 2 and Wave 3 follow-up interviews were administered using Computer Assisted Telephone Interviews (CATI) by the National Opinion Research Center at the University of Chicago. The interview data may be augmented by linkage to Medicare records, the National Death Index, and multiple cause-of-death records.

Study on Global Ageing and Adult Health, Pilot Study, 2005

Investigators: World Health Organization

The World Health Organization (WHO) Multi-Country Studies unit developed the Study on Global Ageing and Adult Health (SAGE) as part of a Longitudinal Survey Program to compile comprehensive longitudinal information on the health and well being of adult populations. The primary objectives of the SAGE survey program are: To 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; To 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; To 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; and To collect health examination and biomarker data that improves reliability of morbidity and risk factor data and to objectively monitor the effect of interventions. Additional objectives include: To 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; To develop a mechanism to link survey data to demographic surveillance site data; To build linkages with other national and multi-country ageing studies; To improve the methodologies to enhance the reliability and validity of health outcomes and determinants data; and To 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. The SAGE study collects data on respondents aged 18+ years, with an emphasis on populations aged 50+ years, from nationally representative samples in six countries: China, Ghana, India, Mexico, Russian Federation and South Africa. The SAGE questionnaire was piloted in over 1500 respondents in Ghana, India and Tanzania in 2005.
