Longitudinal Studies
Wisconsin Longitudinal Study (WLS)
The Wisconsin Longitudinal Study (WLS) is a long-term study of a random sample of 10,317 men and women who graduated from Wisconsin high schools in 1957. Wide-ranging survey data were collected from the graduates or their parents in 1957, 1964, 1975, 1992, 2004, and 2011; from a selected sibling in 1977, 1994, 2005, and 2011; from the spouse of the graduates in 2004; and from the spouse of the selected sibling in 2006. WLS has been in the field conducting cognitive assessments since 2020, with blood biomarker collection starting in 2024.
Midlife in the United States (MIDUS)
Midlife in the United States (MIDUS) is a national sample of continental U.S. residents, aged 25 to 74, who were first interviewed in 1995-96. The original study was conceived by a multidisciplinary team of investigators interested in the influence of psychological, behavioral, and social factors on health, broadly defined, as people age from early adulthood to later life. Longitudinal follow-up has added a comprehensive array of biological and neurological assessments for the original cohort as well as refresher samples.
Survey of the Health of Wisconsin (SHOW)
The Survey of the Health of Wisconsin (SHOW) is the only ongoing statewide-representative cohort, modeled after NHANES. SHOW has retrospective data and biospecimen available for use and offers prospective services to investigators to follow-up the cohort or recruit new participants. SHOW supports basic, clinical, and translational research, in addition to epidemiology studies and public health biomonitoring projects.
National Survey of Families and Households (NSFH)
The National Survey of Families and Households (NSFH) was designed to provide a broad range of information on family life to serve as a resource for research across disciplinary perspectives. A considerable amount of life-history information was collected, including: the respondent's family living arrangements in childhood, departures and returns to the parental home, and histories of marriage, cohabitation, education, fertility, and employment.
High School & Beyond (HS&B:80)
High School and Beyond (HS&B:80) is a panel study of a nationally representative sample of ~15,000 sophomores and ~12,000 seniors attending high schools in the United States in 1980. Resurveyed periodically since that time (most recently in 2021), the data include measures of social background, educational opportunities and achievements (including test scores and transcripts), labor market outcomes, family, and health (including saliva- and blood-based biomarkers in the 2021 data collection). HS&B:80 and NLS 72 are both a part of EdShare.
National Longitudinal Study of the High School Class of 1972 (NLS 72)
National Longitudinal Study of the High School Class of 1972 (NLS 72) is a large, diverse, nationally representative cohort study that began with a random sample of American high school seniors in 1972. Follow-up surveys were conducted between 1973 and 1986. The sixth follow-up survey will begin in 2024, with participants who will then be ~70 years old. NLS 72 and HS&B:80 are both a part of EdShare.
Latin American Mortality Database (LAMBdA)
The Latin American Mortality Database (LAMBdA) supports the study of mortality trends in Latin American countries from 1848 to 2014.
Survey on Health, Well-Being, and Aging in Latin America and the Caribbean (SABE)
Survey on Health, Well-Being, and Aging in Latin America and the Caribbean (SABE) is a cross-national survey on health and aging organized as a cooperative venture among researchers in Argentina, Barbados, Brazil, Chile, Cuba, Mexico and Uruguay. SABE has produced the first cross-national database for studying health and aging in these countries.
Puerto Rican Elderly: Health Conditions (PREHCO)
