Adaptation Process of Cuban and Mexican Immigrants in the United States, 1972-1979 (ICPSR 9672)

Released/updated on: 2006-01-18
Geographic coverage: United States
Time period: 1972-01-01--1979-01-01
For this data collection, Cuban and Mexican male immigrants were interviewed upon their entry into the United States in 1973-1974, with follow-up interviews in 1976 and 1979. The project sought to explore the causes and results of changes that occur following immigration by examining the complex interrelationships between the effects of what immigrants "bring with them" and the social and economic context that receives them. The first interview elicited demographic information such as marital status, number of children, education, parental information, present and prior occupations, date and community of birth, prior residency in the United States, present residency, relatives and friends in the United States, religious practices, and association membership. Respondents were also asked about their reasons for coming to the United States, plans to change residency, perceptions of discrimination in the United States, and aspirations concerning future occupations, salaries, education, and opportunities to reach their goals. Subsequent interviews expanded upon or recorded changes in these areas and also added wife's information and items on perceptions of problems in the United States, ethnicity of social relationships and neighborhood, satisfaction with living in the United States, plans to return to their homeland, languages spoken, read, and listened to, whether residence was owned or rented, and whether respondent had become a United States citizen. The study also recorded Duncan Scores, Treiman Scores, and scores on the Kahl Modernity Index, Knowledge of English Index, and Knowledge of U.S. Index.

Daily In-Home Activity Metrics from the Intelligent Systems for Assessing Aging Changes (ISAAC), Portland, Oregon, 2011 (ICPSR 35063)

Released/updated on: 2014-06-18
Geographic coverage: Oregon, United States, Portland (Oregon)
The ISAAC study developed methods of continuously assessing behaviors of seniors living independently in the community, with the ultimate goal of identifying trends in behavior and activity measures that would be predictive of a later transition to Mild Cognitive Impairment. Homes of participants were instrumented with wireless motion and door sensors, which captured movements throughout the home as they occurred. Participants were monitored continuously for about three years. Participants were also evaluated annually with a full clinical and neuropsychological battery of tests. Algorithms were developed to derive measures of motor activity (median walking speed, number of walks along a chosen path in the home, time spent out of the home, number of room transitions), measures of computer use (number of computer sessions and total time spent on the computer), and measures of nighttime activity (sleep latency, total time in bed, number of bathroom visits at night, motion in bed at night, etc.).

Human Aging: A Biological and Behavioral Longitudinal Study of Healthy Aged Males, 1957-1968 (ICPSR 7678)

Released/updated on: 2006-01-12
Geographic coverage: United States
Time period: 1957-01-01--1968-01-01
This data collection contains data gathered in a longitudinal study of a sample of men aged 65 to 92 who were in good health during the first wave of the study in 1957. The chief aim of the study was to focus on the nature of the normal aging process in individuals of advanced age. The 47 study participants had not suffered from accidents, illnesses, severe emotional or personality problems, or environmental difficulties that might have led to premature aging, but 20 participants showed evidence of asymptomatic subclinical disease. This group represented the typical or "average" healthy aged individual with minimal degrees of physical pathology. Five years later, in 1962, a follow-up study was conducted with 29 of the 39 men still alive. The second follow-up, done in 1968, involved 19 of the surviving 23 men. The data are arranged in files by year: 1957, 1962, and 1968. Included are psychiatric data and medical evaluative data as well as various psychological and medical test scores (e.g., psychometric data, electroencephalographic data, audiological test data, responses to the Minnesota Multiphasic Personality Inventory (MMPI), Rorschach test results, personality test results, Inflund Selective Recall Test results, audiometric conduction findings, clinical psychology ratings, cerebral blood flow, and metabolism studies), and biographical and demographic data.

Midlife in the United States (MIDUS 2): Biomarker Project, 2004-2009 (ICPSR 29282)

Released/updated on: 2025-06-18
Geographic coverage: United States
Time period: 2004-07-30--2009-05-31

The Biomarker study is Project 4 of the Midlife in the United States (MIDUS) longitudinal study, a national survey of more than 7,000 Americans (aged 25 to 74) begun in 1994. The purpose of the larger study was to investigate the role of behavioral, psychological, and social factors in understanding age-related differences in physical and mental health. With support from the National Institute on Aging (NIA), a longitudinal follow-up of the original MIDUS samples [core sample (N = 3,487), metropolitan over-samples (N = 757), twins (N = 957 pairs), and siblings (N = 950)] was conducted in 2004-2006. Guiding hypotheses, at the most general level, were that behavioral and psychosocial factors are consequential for health (physical and mental). A description of the study and findings from it are available on the MIDUS website.

The Biomarker Project (Project 4) of MIDUS 2 contains data from 1,255 respondents. These respondents include two distinct subsamples, all of whom completed the Project 1 Survey: (1) longitudinal survey sample (n = 1,054) and (2) Milwaukee sample (n = 201). The Milwaukee group contained individuals who participated in the baseline MIDUS Milwaukee study, initiated in 2005. The purpose of the Biomarker Project (Project 4) was to add comprehensive biological assessments on a subsample of MIDUS respondents, thus facilitating analyses that integrate behavioral and psychosocial factors with biology. The broad aim is to identify biopsychosocial pathways that contribute to diverse health outcomes. A further theme is to investigate protective roles that behavioral and psychosocial factors have in delaying morbidity and mortality, or in fostering resilience and recovery from health challenges once they occur. The research was not disease-specific, given that psychosocial factors have relevance across multiple health endpoints.

Biomarker data collection was carried out at three General Clinical Research Centers (at UCLA, University of Wisconsin, and Georgetown University). The biomarkers reflect functioning of the hypothalamic-pituitary-adrenal axis, the autonomic nervous system, the immune system, cardiovascular system, musculoskeletal system, antioxidants, and metabolic processes. Our specimens (fasting blood draw, 12-hour urine, saliva) allow for assessment of multiple indicators within these major systems. The protocol also included assessments by clinicians or trained staff, including vital signs, morphology, functional capacities, bone densitometry, medication usage, and a physical exam. Project staff obtained indicators of heart-rate variability, beat to beat blood pressure, respiration, and salivary cortisol assessments during an experimental protocol that included both a cognitive and orthostatic challenge. Finally, to augment the self-reported data collected in Project 1, participants completed a medical history, self-administered questionnaire, and self-reported sleep assessments. For respondents at one site (UW-Madison), objective sleep assessments were also obtained with an Actiwatch(R) activity monitor.

Midlife in the United States (MIDUS Refresher 1): Biomarker Project, 2012-2016 (ICPSR 36901)

Released/updated on: 2019-11-18
Geographic coverage: United States
Time period: 2012-10-01--2016-08-01

The MIDUS Refresher study Survey (2011-2014 ICPSR 36532) recruited a national probability sample of 3,577 adults, aged 25 to 74, designed to replenish the original MIDUS 1 baseline cohort and paralleling the five decadal age groups of the MIDUS 1 baseline survey (ICPSR 2760). The MIDUS Refresher survey employed the same comprehensive assessments as those assembled on the core longitudinal MIDUS sample, but with additional questions about impacts of the economic recession of 2008-09. The MIDUS Refresher Biomarker study (2012-2016) obtained data from 863 respondents (n=746 Main sample, n=117 African Americans from Milwaukee) who completed the MIDUS Refresher Survey.

The purpose of the Refresher Biomarker Project (Project 4) parallels that of the MIDUS 2 Biomarker project (ICPSR 29282), which collected comprehensive biological assessments on a subsample of MIDUS respondents, thus facilitating analyses that integrate behavioral and psychosocial factors with biological regulation/dysregulation, broadly defined. The aim was to use such data to explicate biopsychosocial pathways that contributed to diverse health outcomes. A further theme was to examine period effects on health (mental and physical) related to the economic recession by comparing the pre-recession MIDUS sample with the post-recession MIDUS Refresher sample. A further objective of the MIDUS Refresher sample was to strengthen cross-project analyses by increasing the sample sizes available for testing hypotheses regarding the interplay of key factors (e.g., socioeconomic status, gender, psychosocial factors, biological factors) in mid- and later-life health.

Biomarker data collection was carried out at hypothalamic-pituitary-adrenal axis, the autonomic nervous system, the immune system, cardiovascular system, musculoskeletal system, antioxidants, and three General Clinical Research Centers (at UCLA, University of Wisconsin, and Georgetown University). The biomarkers reflect functioning of the metabolic processes. Our specimens (fasting blood draw, 12-hour urine, saliva) allowed for assessment of multiple indicators within these major systems. The protocol also included assessments by clinicians or trained staff, including vital signs, morphology, functional capacities including 3 dimensional gait analysis, bone densitometry, body composition, ankle brachial index, medication usage, and a physical exam. Project staff obtained indicators of heart-rate variability, beat to beat blood pressure, respiration, and salivary cortisol assessments during an experimental protocol that included both a cognitive and orthostatic challenge. Finally, to augment the self-reported data collected in Survey (Project 1), participants completed a medical history, self-administered questionnaire, and self-reported sleep assessments. For respondents at one site (UW-Madison), objective sleep assessments were also obtained with an Actiwatch(R) activity monitor.
