The Aging, Status, and Sense of Control (ASOC) was conducted during 1995, 1998 and 2001 and examined the relationship between age and changes in the sense of control over one's life. Part I contains data for Waves I and II. Respondents were queried about their physical health, including activities of daily living such as shopping, walking, and doing housework, along with medical conditions such as heart disease, high blood pressure, lung disease, breast cancer, diabetes, arthritis or rheumatism, osteoporosis, and allergies or asthma. Questions regarding mental health investigated difficulties staying focused, feelings of sadness or anxiety, and enjoyment of life. Respondents were also asked about their health behaviors, including use of tobacco and alcohol, frequency of exercise, use of medical services including insurance coverage, and the number of prescription medications used. Also examined was respondents' sense of control over their lives, including social support and participation, and history of adversity, which covered such topics as home or apartment break-ins or assaults, major natural disasters, unemployment longer than six months, and times without enough money for clothes, food, rent, bills, or other necessities. Demographic questions included age, sex, marital status, education, work status, marital and family relations, and socioeconomic status. Wave III (Part 2) was collected in 2001 and contains data on the same questions such as physical health, mental health and health behaviors.

These data constitute the second wave of a survey designed to study the influence of health practices and social relationships on the physical and mental health of a typical sample of the population. The first wave (HEALTH AND WAYS OF LIVING STUDY, 1965 PANEL [ALAMEDA COUNTY, CALIFORNIA] [ICPSR 6688]) collected information for 6,928 respondents (including approximately 500 women aged 65 years and older) on chronic health conditions, health behaviors, social involvements, and psychological characteristics. The 1974 questionnaire was sent to 6,246 living subjects who had responded in 1965, and were able to be located. A total of 4,864 individuals responded in 1974. Questions were asked on marital and life satisfaction, parenting, physical activities, employment, and childhood experiences. Demographic information on age, race, height, weight, education, income, and religion was also collected. Included with this dataset is a separate file (Part 2) containing mortality data for respondents who died between the 1965 and 1974 panels, and information on nonrespondents.

This collection provides a 30-year follow-up with respondents from Alameda County who were originally interviewed in 1965 for the first wave of the Health and Ways of Living Study. The purpose of the survey was to explore the influences of health practices and social relationships on the physical and mental health of a typical sample of the population. The first wave of the study, HEALTH AND WAYS OF LIVING STUDY, 1965 PANEL: [ALAMEDA COUNTY, CALIFORNIA] (ICPSR 6688), collected information for 6,928 respondents (including approximately 500 women aged 65 years and older) on chronic health conditions, health behaviors, social involvements, and psychological characteristics. The second wave, the 1974 panel (ALAMEDA COUNTY [CALIFORNIA] HEALTH AND WAYS OF LIVING STUDY, 1974 PANEL [ICPSR 6838]), collected information from 4,864 of the original respondents. The third and fourth waves (1994 and 1995 panels, respectively), provided in this collection, explore some new topics. The third wave provides a follow-up of 2,729 original 1965 and 1974 respondents and examines health behaviors such as alcohol consumption and smoking habits, along with social activities. Also included is information on health conditions such as diabetes, osteoporosis, hormone replacement, and mental illness. Another central topic investigated is activities of daily living (including self-care such as dressing, eating, and shopping), along with use of free time and level of involvement in social, recreational, religious, and environmental groups. The fourth wave is a follow-up to the 1994 panel, and contains 2,569 cases. This wave examines changes in functional abilities such as self-care activities, employment, involvement in community activities, visiting friends/family, and use of free time since 1994.

This fifth wave of data, collected in 1999, provides follow-up with 2,123 respondents from Alameda County who were originally interviewed in 1965 for the first wave of the Health and Ways of Living Study. The purpose of the survey was to explore the influences of health practices and social relationships on the physical and mental health of a typical sample of the population. Part 2 of this collection contains mortality data including cause and year of death. The first wave of the study, HEALTH AND WAYS OF LIVING STUDY, 1965 PANEL: [ALAMEDA COUNTY, CALIFORNIA] (ICPSR 6688), collected information for 6,928 respondents (including 360 men and 530 women aged 65 years and older) on chronic health conditions, health behaviors, social involvements, and psychological characteristics. The second wave, the 1974 panel, ALAMEDA COUNTY [CALIFORNIA] HEALTH AND WAYS OF LIVING STUDY, 1974 PANEL (ICPSR 6838), collected information from 4,864 of the original respondents. The third and fourth waves, ALAMEDA COUNTY [CALIFORNIA] HEALTH AND WAYS OF LIVING STUDY, 1994 and 1995 PANELS (ICPSR 3083), provided a follow-up of 2,729 original 1965 and 1974 respondents. The fourth wave is a follow-up to the 1994 panel and contains 2,569 cases.

The Americans' Changing Lives (ACL) survey series is an ongoing, nationally representative, longitudinal study focusing especially on differences between Black and White Americans in middle and late life. These data constitute the first, second, third, fourth, fifth, and sixth waves in a panel survey covering a wide range of sociological, psychological, mental, and physical health items. Wave I of the study began in 1986 with a nation face-to-face survey of 3,617 adults ages 25 and up, with Black Americans and people aged 60 and over over-sampled at twice the rate of the others. Wave II constitutes face-to-face re-interviews in 1989 of those still alive. Survivors have been re-interviewed by telephone, and when necessary face-to-face, in 1994 (Wave III), 2001/02 (Wave IV), 2011 (Wave V), and 2019/21 (Wave VI). Please note that for Wave VI, the majority of data collection occurred in 2019, with only a small subset (n=39) of participants surveyed in 2021. ACL was designed and sought to investigate the following: (1) The ways in which a wide range of activities and social relationships that people engage in are broadly "productive," (2) how individuals adapt to acute life events and chronic stresses that threaten the maintenance of health, effective functioning, and productive activity, and (3) sociocultural variations in the nature, meaning, determinants, and consequences of productive activity and relationships. Among the topics covered are interpersonal relationships (spouse/partner, children, parents, friends), sources and levels of satisfaction, social interactions and leisure activities, traumatic life events (physical assault, serious illness, divorce, death of a loved one, financial or legal problems), perceptions of retirement, health behaviors (smoking, alcohol consumption, overweight, rest), and utilization of health care services (doctor visits, hospitalization, nursing home institutionalization, bed days). Also included are measures of physical health, psychological well-being, and indices referring to cognitive functioning. Demographic information provided for individuals includes household composition, number of children and grandchildren, employment status, occupation and work history, income, family financial situation, religious beliefs and practices, ethnicity, race, education, sex, and region of residence.

The American Health Values Survey was conducted by the National Opinion Research Center (NORC) at the University of Chicago in order to develop a typology of Americans based on their health values and beliefs. The survey examined values and beliefs related to health at both the individual as well as societal levels. The survey assessed the importance of health in day-to-day personal life (i.e. the amount of effort spent on disease prevention as well as appropriate seeking of medical care); equity, the value placed on the opportunity to succeed generally in life as well as on health equity; social solidarity, the importance of taking into account the needs of others as well as personal needs; health care disparities, views about how easy/hard it is for African Americans, Latinos and low-income Americans to get quality health care; and, the importance of the social determinants of health. In addition, the survey also explored views about how active government should be in health; collective efficacy, the ease of affecting positive community change by working with others; and health-related civic engagement e.g. the support of health charities and organizations working on health issues.

The American Time Use Survey (ATUS) collects information on how people living in the United States spend their time. Data collected in this study measured the amount of time that people spent doing various activities in 2006, such as paid work, child care, religious activities, volunteering, and socializing. Respondents were interviewed only once about how they spent their time on the previous day, where they were, and whom they were with. An Eating and Health (EH) module was introduced in January 2006, which included questions related to eating, meal preparation, and health, all of which were asked after completion of the ATUS questions. Part 1, Respondent and Activity Summary File, contains demographic information about respondents and a summary of the total number of minutes they spent doing each activity that day. Part 2, Roster File, contains information about household members and nonhousehold children under the age of 18. Part 3, Activity File, includes additional information on activities in which respondents participated, including the location of each activity and the total time spent on secondary child care. Part 4, Who File, includes data on who was present during each activity. Part 5, ATUS-CPS 2006 File, contains data on respondents and members of their household collected during their participation in the Current Population Survey (CPS). Parts 6 and 7 correspond to the 2006 Eating and Health (EH) Module. Parts 8-12 contain supplemental data files that can be used for further analysis of the data. Part 8, Case History File, contains information about the interview process. Part 9, Call History File, gives information about each call attempt. Part 10, Trips File, provides information about the number, duration, and purpose of overnight trips away from home for two or more nights in a row in a given reference month. Parts 11 and 12 contain base weights, replicate base weights, and replicate final weights for each case that was selected to be interviewed for the ATUS. Demographic variables include sex, age, race, ethnicity, education level, income, employment status, occupation, citizenship status, country of origin, and household composition.

The main objective of this pragmatic randomized clinical trial (PCT) is to identify the optimal dose of aspirin for secondary prevention in atherosclerotic cardiovascular disease (ASCVD). A total of 15,076 high-risk patients with a history of a myocardial infarction (MI) or documented ASCVD were randomized in a 1:1 ratio to receive 81 mgs versus 325 mgs of aspirin every day. This trial addressed the following specific aims: To compare the effectiveness of two doses of aspirin (81 mg and 325 mg) in reducing a composite of all-cause mortality and hospitalization for nonfatal MI, or nonfatal stroke, and the primary safety endpoint of major bleeding. Secondary endpoints include the components of the primary endpoint and hospitalization for transient ischemic attack, unstable angina, or coronary revascularization procedures. To compare the effects of aspirin in selected subgroups of patients by sex, age, race, Internet users vs. non-users, and those with diabetes or advanced chronic kidney disease (CKD). To develop and refine the infrastructure for PCORnet to conduct multiple comparative effectiveness trials in the future. To explore biological mediators of heterogeneity of response to aspirin and of impact on clinical events.

The Behavioral Risk Factor Surveillance System (BRFSS) is a system of health-related telephone surveys that collect state data about U.S. residents regarding their health-related risk behaviors, chronic health conditions, and use of preventive services. Established in 1984 with 15 states, BRFSS now collects data in all 50 states as well as the District of Columbia and three U.S. territories. BRFSS completes more than 400,000 adult interviews each year.

This collection includes a combined dataset of the Generations study wave 1 (baseline) survey and the TransPop study transgender survey. The two studies have many overlapping variables, and they examined topics such as respondents' health outcomes and behaviors, experiences with discrimination, identity, and transition-related experiences. Data from these studies were merged to allow for analysis of the combined LGBT populations. This dataset has also been reweighted to be representative of these populations. The complete Generations study data (baseline, wave 2, and wave 3 survey data) can be found under study number 37166, and the complete TransPop study data (transgender and cisgender survey data) can be found under study number 37938. For detailed information on the Generations and TransPop studies, including related publications, please refer to their respective DSDR/ICPSR study pages.

The Common Cold Project began in 2011 with the aim of creating, documenting, and archiving a database that combines final research data from 5 prospective viral-challenge studies that were conducted over the preceding 25 years. The data collection includes the British Cold Study (BCS), which focused on psychological stress; the Pittsburgh Cold Study 1 (PCS1), which built on the BCS; the Pittsburgh Cold Study 2 (PCS2), which examined childhood socioeconomic status and personality; the Pittsburgh Mind-Body Center Cold Study (PMBC), which recorded detailed mood and behavior data over 14 days; the Pittsburgh Cold Study 3, which focused on childhood environment; the Pittsburg Cold Study 3 Social Rhythm Data (PCS3-SRM), which recorded daily interview data of mood, health behavior, and social interaction; and finally the 5 Study Aggregate, which was designed to facilitate analysis across studies. These studies assessed predictor (and hypothesized mediating) variables in healthy adults aged 18 to 55 years, experimentally exposed them to a virus that causes the common cold, and then monitored them for development of infection and signs and symptoms of illness. Standard control variables (covariates) included age, sex, socioeconomic status (SES), race/ethnicity, body mass index (BMI), season of the year, and specific antibody (Ab) titer to the challenge virus (specific immunity). Three of the studies also include daily evening interviews (conducted for 6 or 14 days before exposure to a virus and assessing daily social interactions, mood, health behaviors, and physical symptoms; and daily diaries collected during the quarantine period (1 day before and 5-6 days after viral exposure), including cold-specific and nonspecific symptoms, mood, and health behaviors. These data accompany datasets four, five, and seven. Many common variables were collected across 2 or more studies, and all 5 studies include measures of upper respiratory infectious illness (URI) (e.g., infection, signs and symptoms of a cold, local [nasal mucosa] release of pro- and anti-inflammatory cytokines). Data were also collected on a broad assortment of health-related outcomes not specific to URI including anthropomorphic measures (such as body mass index and waist circumference), complete blood cell counts and differentials, measures of functional immunity, self-reported and objectively assessed health behaviors (smoking, alcohol consumption, physical activity, diet, and sleep), measures of functional physiology across several biological systems (such as pulmonary function, resting cardiovascular function, endocrine, and metabolic activity), and self-reported assessments of physical and psychological health and well-being. In addition, the 5 studies collected data on an extensive range of demographic, health behavior, psychological and social variables including adult SES and subjective social standing, childhood SES, major stressful life events and perceived stress, personality, psychological expectations and beliefs, social relationships, and state and trait affect.

This collection contains data and documentation for the fourth round of the Community Tracking Study (CTS) Household Survey. Sponsored by the Robert Wood Johnson Foundation, the CTS is a national study designed to track changes in the United States' health care system and their effects. The fourth round was administered to households in the 60 CTS sites: 51 metropolitan areas and nine nonmetropolitan areas which were randomly selected to form the core of the CTS and to be representative of the nation as a whole. The first round of the CTS Household Survey was conducted in 1996-1997 (ICPSR 2524), the second round in 1998-1999 (ICPSR 3199), and the third in 2000-2001 (ICPSR 3764). Respondents to the fourth round provided information about health insurance coverage, use of health services, unmet needs for health care, children's special health care needs, out-of-pocket medical costs, patient trust in physicians, sources of health information, attitudes about medical care, and satisfaction with health care and health plans. Health status, chronic conditions, and risk attitudes and smoking behavior were additional topics covered by the fourth round questionnaire. The data include variables on height and weight, employment, income, ethnicity, race, United States citizenship, household composition, and demographic characteristics.

The purpose of this study was to pilot test the potential for improvement in antiretroviral medication adherence of an adapted group-based, multi-session, community-based Antiretroviral Therapy (ART) adherence and risk reduction intervention, Project ADHerence Education and Risk Evaluation (ADHERE). Project ADHERE was compared to a single-session group-based medication adherence intervention, Medication Adherence and Care Engagement (MACE). A secondary aim was to examine the impact of Project ADHERE on HIV risk behaviors (i.e., illicit drug use and unprotected sexual behavior). Formerly incarcerated Black drug offenders are at an elevated risk for HIV infection. Despite substantial research expressing the need for HIV prevention services for ex-offenders postrelease, this population has limited access to quality programming and services related to HIV risk reduction. This study seeks to inform and adapt an HIV risk reduction intervention to address the needs of formerly incarcerated Black drug offenders who are being released from prisons in the New York City metropolitan area. The study utilizes qualitative and quantitative methods to inform and adapt an HIV prevention intervention for this study population.

This data collection is part of the 1985 Continuing Survey of Food Intakes by Individuals (CSFII) and provides information on 1-day dietary intakes of men 19 to 50 years of age living in the United States in 1985. Two separate population groups of men were surveyed: (1) a sample of men of all incomes drawn from all private households, and (2) a smaller sample of men drawn from households with reported incomes at or below 130 percent of the poverty guidelines. Part 1, Respondent Demographics and Nutrient Intake File, contains demographic information on each respondent in the household selected to be interviewed, as well as the respondent's use of special diets, vitamin and mineral supplements, and a summary of the nutrient content of the foods eaten by that individual. Part 2, Household File, contains information on basic characteristics of the respondent's household, including participation in food welfare programs. Part 3, Detailed Food Intake File, includes information on the type and amount of each food item eaten at home or away, the time of day the food was eaten, and the use of salt and fat in the food preparation. A Food Instruction Booklet, included with the data collection instrument, was used to help respondents describe foods and amounts eaten. Demographic information on respondents include age, race, education level, employment status, occupation, height, weight, and health status. Household characteristics include the age, education level, occupation, and employment status of the male head of the household, the sex and age of household members, household income, tenancy status of the residence, and type of residential area (e.g., urban or rural).

The Costa Rican Longevity and Healthy Aging Study (CRELES, or Costa Rica Estudio de Longevidad y Envejecimiento Saludable) is a nationally representative longitudinal survey of health and lifecourse experiences of 2,827 Costa Ricans ages 60 and over in 2005, the baseline collection. CRELES-2 refers to the second wave of visits in this longitudinal study, and includes the results from these visits. The first wave of interviews, or baseline, of CRELES is also available at http://doi.org/10.3886/ICPSR26681. The second wave fieldwork was conducted from October 2006 to July 2008, with 2,364 surviving and contacted participants. The original sample was drawn from Costa Rican residents in the 2000 population census who were born in 1945 or before, with an over-sample of the oldest-old (ages 95 and over). Vital statistics indicate that Costa Rica has an unusually high life expectancy for a middle-income country, even higher than that of the United States, but CRELES is the first nationally representative survey to investigate adult health levels in Costa Rica. CRELES public use data files contain information on a broad range of topics including self-reported physical health, psychological health, living conditions, health behaviors, health care utilization, social support, and socioeconomic status. Objective health indicators include anthropometrics, observed mobility, and biomarkers from fasting blood samples (such as cholesterol, glycosylated hemoglobin, and C-reactive protein). Mortality events are tracked and conditions surrounding death are measured in a surviving family interview.

The Costa Rican Longevity and Healthy Aging Study (CRELES, or Costa Rica Estudio de Longevidad y Envejecimiento Saludable) is a nationally representative longitudinal survey of health and lifecourse experiences. CRELES-3 refers to the third wave of visits in this longitudinal study. The first two waves are available as ICPSR 26681 and ICPSR 31263. The original sample (Wave 1) was drawn from Costa Rican residents in the 2000 population census who were born in 1945 or before, with an over-sample of the oldest age range (ages 95 and over). A total of 2,827 Costa Ricans ages 60 and over participated in 2005. The second wave revisited the same participant group. The data presented here represent the third wave of fieldwork that was conducted from February 2009 to January 2010, with 1,855 surviving and contacted participants. CRELES data include factors contributing to older adults' length and quality of life. Among these data are self-reported physical health, psychological health, living conditions, health behaviors, health care utilization, social support, and socioeconomic status. Objective health indicators typically included in this series are anthropometrics, observed mobility, and biomarkers from fasting blood (such as cholesterol, glycosylated hemoglobin, and C-reactive protein). However, the third wave did not collect blood. Data regarding participants' deaths and conditions surrounding death were collected from interviews of surviving family members and are included in Wave 2 and Wave 3 data files. The collection includes a tracking file (Dataset 13) which links participants across the three waves and includes sampling weights. Demographic data included in the study include age during each wave, sex, marital status, education, number of children, type of housing, and geographic region in Costa Rica. Some elements of the demographic data are found only in Wave 1 and require linking the CRELES-3 data files with ICPSR 26681.

This survey explored the ways in which social influences, such as stress and racism, affected health, and the impact these influences had on the respondents' outlook on life. Respondents were questioned about their health status and their exercise, smoking, sleeping, and dieting habits, as well as about diagnosed health problems and depression and their effects on daily activities. Respondents were also asked a series of questions regarding their employment status, type of job and whether it was a supervisory position, the racial makeup of their workgroup, their perceptions of their position and job, the likelihood of their finding another job, hassles experienced while at work, and whether they had any trouble balancing family and work. Another series of questions asked respondents whether they had been a victim of a serious physical attack or assault, robbery, or home burglary, if they had ever been unfairly searched, stopped, or questioned by police, why they felt they had been treated this way, and if they felt they had ever been treated unfairly by a teacher, landlord, or neighbor. Opinions were also solicited on the respondents' experience with depression and anxiety. Respondents were asked whether they felt it was possible to reach their goals, how satisfied they were with their present situation, how often they felt depressed and how long this feeling lasted, whether they lost weight or sleep due to this feeling, how this feeling of depression made them view themselves, how often and how long they were worried about things that were not likely to happen, how often they worried about non-serious things, and how they felt physically when they were anxious or depressed. Another set of questions queried respondents on alcohol and drug use. Respondents were asked how often they drank alcohol, the most they had to drink at one time, whether they had experienced any addiction to alcohol or experienced any emotional or psychological problems associated with drinking, whether they had any problem controlling their drinking, whether they had used drugs outside of a doctor's order, what types of drugs they had used, how often and in what type of situations they had used these drugs, and whether they had any addiction to the drugs. Respondents were also asked whether they had a regular doctor, whether they went to a doctor's office or clinic to seek medical attention, the last time they had gone for a checkup, how they were treated by staff at the visit, whether they trusted their doctor, the reasons why they did or did not receive medical attention, and whether they had health insurance. Respondents were also asked for their perceptions of differences between Blacks and whites, attitudes toward affirmative action with regard to employment, and their attitude toward interracial relationships. Another battery of questions queried respondents on any fears or phobias they had, such as a fear of animals, water, or visiting a doctor or dentist. Questions focused on the severity of these fears, how long they had had these fears, and how much these fears interfered in daily activities. A final set of questions gathered demographic information on respondents such as highest level of education completed, political affiliation, religious affiliation, level of religious participation, importance of religion, birth date, whether they owned their own home or rented, how much they spent on food each week, total family income for the year 1994, and the, height and weight of respondents.

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents aged 18 and older. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households in 2016 and has since been refreshed through additional address-based sampling annually. Between November 3 and December 15, 2021, 2,662 previously-enrolled panelists were invited to participate in a self-administered online or interviewer-administered telephone survey. A total of 1,900 Detroit residents completed the survey, yielding an overall response rate of 72% (using AAPOR Response Rate 1). Topics include experience with COVID-19; COVID-19 vaccine receipt, attitudes and trust; employment and economic precarity; neighborhood satisfaction; neighborhood change; as well as healthcare usage; the Child Tax Credit; and Digital Inclusion.

The Drug Abuse Warning Network (DAWN) survey is designed to capture data on emergency department (ED) episodes that are induced by or related to the use of an illicit, prescription, or over-the-counter drug. For purposes of this collection, a drug "episode" is an ED visit that was induced by or related to the use of an illegal drug or the nonmedical use of a legal drug for patients aged six years and older. A drug "mention" refers to a substance that was mentioned during a drug-related ED episode. Because up to four drugs can be reported for each drug abuse episode, there are more mentions than episodes in the data. Individual persons may also be included more than once in the data. Within each facility participating in DAWN, a designated reporter, usually a member of the emergency department or medical records staff, was responsible for identifying drug-related episodes and recording and submitting data on each case. An episode report was submitted for each patient visiting a DAWN emergency department whose presenting problem(s) was/were related to their own drug use. DAWN produces estimates of drug-related emergency department visits for 50 specific drugs, drug categories, or combinations of drugs, including the following: acetaminophen, alcohol in combination with other drugs, alprazolam, amitriptyline, amphetamines, aspirin, cocaine, codeine, diazepam, diphenhydramine, fluoxetine, heroin/morphine, inhalants/solvents/aerosols, LSD, lorazepam, marijuana/hashish, methadone, methamphetamine, and PCP/PCP in combination with other drugs. The use of alcohol alone is not reported. The route of administration and form of drug used (e.g., powder, tablet, liquid) are included for each drug. Data collected for DAWN also include drug use motive and total drug mentions in the episode, as well as race, age, patient disposition, reason for ED visit, and day of the week, quarter, and year of episode.

The East Asian Social Survey (EASS) is a biennial social survey project that serves as a cross-national network of the following four General Social Survey type surveys in East Asia: Chinese General Social Survey (CGSS), Japanese General Social Survey (JGSS), Korean General Social Survey (KGSS), Taiwan Social Change Survey (TSCS), and comparatively examines diverse aspects of social life in these regions. Survey information in this module focused on issues that affected overall health, such as specific conditions, physical functioning, aid received from family members or friends when needed, and lifestyle choices. Topics included activities respondents were able to perform and how they were affected socially in light of specific physical and mental health conditions. Respondents were asked to provide health conditions they were suffering from, such as hypertension, diabetes, heart disease, and how these conditions were limiting with respect to general health, physical functioning, emotional and mental health, as well as social functioning. Other topics included participation and frequency of lifestyle habits that affected overall health, as well as how often respondents visited the doctor. Respondents were also queried on whether they sought out alternative, non-traditional homeopathic care and whether family, friends, or co-workers listened to their personal problems and provided support financially. Additional topics include the environment and pollution, neighborhood amenities, fear of aging, addiction, and body image. Demographic information specific to the respondent and their spouse includes age, sex, marital status, education, employment status and hours worked, occupation, earnings and income, religion, class, size of community, and region.

Please note that as of June 2023, Sarah D. Gunnery, PhD is the current Principal Investigator of this data collection. The Emergence and Evolution of Social Self-Management of Parkinson's Disease study (SocM-PD) is a mixed-method (quantitative-qualitative) prospective cohort study of how people with Parkinson's disease and their primary caregiver (as available) naturalistically manage chronic disease, wellness and social life in their home and community. Researchers define social self-management as the practices and experiences that ensure personal social comfort while supporting mental and physical well-being. Articulating this model will guide research to identify social factors that are deleterious to or protective of quality of life when living with chronic disease. Parkinson's Disease offers a model for studying the effect of physical disease on the social self management of daily life when physical symptoms affect fundamental social capacities. The overall objective is to understand the emergence and evolution of the trajectories of the self-management of the social lives of people living with Parkinson's disease. The central hypothesis is that expressive capacity predicts systematic change in the pattern of social self-management and quality of life outcomes. Demographic variables include age, gender, ethnicity, income, marital status, education, and employment.

The Enhanced Services for the Hard-to-Employ (HtE) Demonstration and Evaluation Project was a 10-year study (taken on by the MDRC) that evaluated innovative strategies aimed at improving employment and other outcomes for groups who faced serious barriers to employment. The Enhanced Services for the Hard-to-Employ is the first comprehensive attempt to understand the diverse low-income population and to test interventions aimed at the most common barriers that are encountered in this population's employment. The HtE demonstration was designed to evaluate a variety of innovative ways to boost employment, reduce welfare receipt, and promote well-being in low-income populations. This study evaluated the effectiveness of the Enhanced Early Head Start (EHS) program on addressing the developmental needs of young children living in poverty by offering enhanced services aimed at proactively addressing the employment and educational needs of their parents. This program included the addition of on-site self-sufficiency specialists to work with program staff and families on topics such as, formalized employment, self-sufficiency services and community partnerships with local employment-focused and educational agencies. The Early Head Start full research sample consists of 610 individuals randomly assigned between August 2004 and December 2006 (305 members in the program group and 305 in the control group). The research team followed the two groups for over three years, using surveys and administrative data. All 610 sample members completed a baseline survey at random assignment, providing basic demographic information, employment and child care history prior to the study. Two follow-up surveys were collected at the 18-month and 42-month mark. At 42-months, respondents who responded to the 18-month survey were asked about child care activities since their earlier survey interview date, while respondents who responded only to the 42-month survey were asked about child care activities since random assignment. Data were collected on receipt of EHS services and assistance programs, TANF history, type and amount of child care used, child immunization records, parenting, child behavior, child social-emotional skills, as well as child reading and math skills. Demographic information includes age, race, marital status, education, source of income, employment status, and public assistance information.

This study analyzed the effectiveness of the Rhode Island "Working toward Wellness" (WTW) program, a one-year program that provided telephonic care management to depressed parents receiving Medicaid in Rhode Island. The Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR) questionnaire was administered to parents in order to identify those with major depression. All consenting parents who were found to have major depression were then assigned to the study. The Working Toward Wellness full research sample consisted of 499 individuals randomly assigned between November 2004 and October 2006 (245 members in the program group and 254 in the control group). The research team followed the two groups for three years using surveys. All 400 sample members completed a baseline survey at random assignment, providing basic demographic information, data on depression, other health outcomes, employment, participation in outreach programs, receipt of behavioral health services, and material hardship prior to enrollment in the study. Three follow up surveys were collected at the sixth month, eighteenth month, and thirty-sixth month marks. The WTW 6, 18, and 36 month reports include data from surveys administered to parents and children; however, only measures used in the adult/parent analysis are included due to restrictions. Care managers recorded information on attempted and completed calls with 230 members in the program group. Data was collected on respondent's general health, depression scores and treatments, substance abuse, work performance and attendance, as well as wages and income. Demographic information includes age, race, marital status, education, employment status, individual and household monthly income, as well as social security and disability status.

The Filipino American Community Epidemiological Study (FACES) is a research project of Asian American Recovery Services, Inc. of San Francisco, California. The four-year study, whose formal title is Alcohol-Related Problems among Filipino Americans, was concluded in 1999. It provides information and data about the health of Filipino Americans of the San Francisco Bay Area and the City and County of Honolulu. The interview asked randomly chosen Filipino American respondents in these two geographic areas about their health, alcohol consumption, mood state, physical symptoms, cultural background and sociodemographic information. The purpose of FACES was to study alcohol and stress-related behaviors of Filipino Americans. Demographic variables include gender, age, race, education level, marital status, household income, military service, and religious preference.

The primary purpose of this project was to harmonize a scale of behavioral health, the Behavior Problems Index (BPI), within and across two publicly-available datasets, the National Longitudinal Survey of Youth Children and Young Adults 1979 (NLSY79) and the Child Development Supplements of the Panel Study of Income Dynamics (PSID-CDS). Each of the original studies followed children longitudinally and their mothers completed the BPI about their behaviors, generally when the children were ages 4 to 14. The analysis generated Stata-formatted datasets which include the children's ages, genders, race/ethnicities; their mothers' age, highest grade completed, and region and urbanicity of residence; their family size, income, income-to-needs ratio, and poverty status; and the BPI item responses and study-created BPI summary scores. Researchers used naming conventions and recodings to conceptually harmonize these variables. For researchers who want to review and modify the codings, the archive includes the Stata code that was used to create the analysis datasets as well as the "raw" data that was extracted from the NLSY79 and PSID-CDS websites. Researchers also analytically harmonized the BPI scale scores using psychometric models. Here, they provide Mplus code that was used to test for measurement invariance and to run the alignment model to link scores as well as R code using user-written harmony package to read the alignment model output. Research reported in this publication was supported by the Eunice Kennedy Shriver National Institute of Child Health and Human Development (NICHD) of the National Institutes of Health.

The Health and Life Study of Koreans (HLSK) was conducted as a part of the study, "Empirical Assessment of Respondent Driven Sampling from Total Survey Error Perspectives" supported by the National Science Foundation. The larger study aimed to examine the operational and inferential properties of respondent driven sampling (RDS). HLSK applied RDS using a web survey, to examine the health of foreign-born Korean-American adults living in Los Angeles County or the State of Michigan. It should be noted that the literature on analysis of RDS data is not fully established, and there is less than clear empirical evidence illustrating the fit of using RDS for population-level inferences. Hence, data users are advised to exercise extreme caution in making population-level inferences. This study uses existing questions from established surveys such as the American Community Survey (ACS), Kessler survey of psychological distress, and the California Health Interview Survey (CHIS). The Main Survey covers topics like socio-demographics, physical and mental health, healthcare utilization, religiosity, political engagement, psychosocial traits, and racial/ethnic identity. The Follow-up Survey and Restricted Data focuses on RDS sampling questions and allows users to examine the relationships between recruiters and their recruits. Additionally, the Follow-up Survey and Restricted Data includes variables that contain sensitive information such as multi-racial identity, citizenship status, and physical health characteristics.

Since 1982, the World Health Organization (WHO) Regional Office for Europe has sponsored a cross-national, school-based study of health-related attitudes and behaviors of young people. These studies, generally known as Health Behavior in School-Aged Children (HBSC), are based on nationally independent surveys of school-aged children in as many as 30 participating countries. The HBSC studies were conducted every four years since the 1985-1986 school year. The United States was one of three countries chosen to implement the survey out of cycle. The data available here are the results of the United States study from the 1995-1996 school year. The study results can be used as stand-alone data, or to compare to the other countries involved in the international HBSC. The HBSC study has two main objectives. The first objective is to monitor health-risk behaviors and attitudes in youth over time to provide background and identify targets for health promotion initiatives. The second objective is to provide researchers with relevant information to understand and explain the development of health attitudes and behaviors through early adolescence. The study contains variables dealing with many types of drugs such as tobacco, alcohol, marijuana, cocaine, inhalants, hallucinogens, and over-the-counter medications. The study also examines a person's health and health behaviors such as eating habits, depression, injuries, anti-social behavior including questions concerning bullying, fighting, using weapons, and how one deals with anger. There are also questions concerning problems with attention span at school and opinions about school itself.

The second objective is to provide researchers with relevant information in order to understand and explain the development of health attitudes and behaviors through early adolescence. The study contains variables dealing with many types of drugs such as tobacco, alcohol, marijuana, inhalants, and any other substances. The study examines the first time these substances were used and the frequency of their use. Other topics include questions about the person's health and other health behaviors. Some of these topics include eating habits, body image, health problems, family make-up, personal injuries, bullying, fighting, and bringing weapons to school. A school administrator and the lead health education teacher also completed individual surveys concerning school programs and policies that affect students' health and the content of various health courses.

The Hispanic Established Populations for the Epidemiologic Studies of the Elderly (Hispanic EPESE) was modeled after the design of the ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1981-1993: [EAST BOSTON, MASSACHUSETTS, IOWA AND WASHINGTON COUNTIES, IOWA, NEW HAVEN, CONNECTICUT, AND NORTH CENTRAL NORTH CAROLINA] (ICPSR 9915) and ESTABLISHED POPULATIONS FOR EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1996-1997: PIEDMONT HEALTH SURVEY OF THE ELDERLY, FOURTH IN-PERSON SURVEY [DURHAM, WARREN, VANCE, GRANVILLE, AND FRANKLIN COUNTIES, NORTH CAROLINA] (ICPSR 2744). The Hispanic EPESE collected baseline data beginning in September 1993 through June 1994 on a representative sample of community-dwelling Mexican-American elderly, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the study was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE attempted to determine whether certain risk factors for mortality and morbidity operate differently in Mexican Americans than in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public use baseline data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression.

This dataset comprises the fifth follow-up of the baseline Hispanic EPESE (HISPANIC ESTABLISHED POPULATIONS FOR THE EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1993-1994: [ARIZONA, CALIFORNIA, COLORADO, NEW MEXICO, AND TEXAS] [ICPSR 2851]). The baseline Hispanic EPESE collected data on a representative sample of community-dwelling Mexican Americans, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The primary purpose of the series was to provide estimates of the prevalence of key physical health conditions, mental health conditions, and functional impairments in older Mexican Americans and to compare these estimates with those for other populations. The Hispanic EPESE provides data on risk factors for mortality and morbidity in Mexican Americans in order to contrast how these factors operate differently in non-Hispanic White Americans, African Americans, and other major ethnic groups. The public-use data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression. Subsequent follow-ups provide a cross-sectional examination of the predictors of mortality, changes in health outcomes, and institutionalization, and other changes in living arrangements, as well as changes in life situations and quality of life issues. During this 6th Wave, 2006-2007, reinterviews were conducted either in person or by proxy, with 921 of the original respondents. This fifth follow-up includes an additional sample of 621 Mexican Americans aged 75 years and over with higher average-levels of education than those of the surviving cohort, increasing the total number of respondents to 1,542. By diversifying the cohort of those aged 75 and older, a better understanding can be gained of the influence of socioeconomic and cultural variations on the lives and health of older Mexican Americans.

The Hispanic EPESE provides data on risk factors for mortality and morbidity in Mexican Americans in order to contrast how these factors operate differently in non-Hispanic White Americans, African Americans, and other major ethnic groups. The Wave 7 dataset comprises the sixth follow-up of the baseline Hispanic EPESE (HISPANIC ESTABLISHED POPULATIONS FOR THE EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1993-1994: [ARIZONA, CALIFORNIA, COLORADO, NEW MEXICO, AND TEXAS] [ICPSR 2851]). The baseline Hispanic EPESE collected data on a representative sample of community-dwelling Mexican Americans, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The public-use data cover demographic characteristics (age, sex, type of Hispanic race, income, education, marital status, number of children, employment, and religion), height, weight, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of dental, hospital, and nursing home services, and depression. Subsequent follow-ups provide a cross-sectional examination of the predictors of mortality, changes in health outcomes, and institutionalization, and other changes in living arrangements, as well as changes in life situations and quality of life issues. During this 7th Wave (dataset 1), 2010-2011, re-interviews were conducted either in person or by proxy, with 659 of the original respondents. This Wave also includes 419 re-interviews from the additional sample of Mexican Americans aged 75 years and over with higher average-levels of education than those of the surviving cohort who were added in Wave 5, increasing the total number of respondents to 1,078. The Wave 7 Informant Interviews dataset (dataset 2) includes data which corresponds to the sixth follow-up of the baseline Hispanic EPESE Wave 7 and included re-interviews with 1,078 Mexican Americans aged 80 years and older. During these interviews, participants were asked to provide the name and contact information of the person they are "closer to" or they "depend on the most for help." These INFORMANTS were contacted and interviewed regarding the health, function, social situation, finances, and general well-being of the ongoing Hispanic EPESE respondents. Information was also collected on the informant's health, function, and caregiver responsibilities and burden. This dataset includes information from 925 informants, more than two-thirds of whom were children of the respective respondents.

The Hispanic EPESE provides data on risk factors for mortality and morbidity in Mexican Americans in order to contrast how these factors operate differently in non-Hispanic White Americans, African Americans, and other major ethnic groups. The Wave 8 dataset comprises the seventh follow-up of the baseline Hispanic EPESE (HISPANIC ESTABLISHED POPULATIONS FOR THE EPIDEMIOLOGIC STUDIES OF THE ELDERLY, 1993-1994: [ARIZONA, CALIFORNIA, COLORADO, NEW MEXICO, AND TEXAS] [ICPSR 2851]). The baseline Hispanic EPESE collected data on a representative sample of community-dwelling Mexican Americans, aged 65 years and older, residing in the five southwestern states of Arizona, California, Colorado, New Mexico, and Texas. The public-use data cover demographic characteristics (age, sex, marital status), height, weight, BMI, social and physical functioning, chronic conditions, related health problems, health habits, self-reported use of hospital and nursing home services, and depression. Subsequent follow-ups provide a cross-sectional examination of the predictors of mortality, changes in health outcomes, and institutionalization, and other changes in living arrangements, as well as changes in life situations and quality of life issues. During this 8th Wave, 2012-2013, re-interviews were conducted either in person or by proxy, with 452 of the original respondents. This Wave also includes 292 re-interviews from the additional sample of Mexican Americans aged 75 years and over with higher average-levels of education than those of the surviving cohort who were added in Wave 5, increasing the total number of respondents to 744.

The purpose of this project was to establish a collection of datasets that could be used (1) to analyze the influence of partnership networks on the transmission of sexually transmitted and blood-borne infections, and (2) to examine the influence of study design on estimation of network properties and impacts. Eight studies contributed datasets to the collection. They include: Colorado Springs Project 90, 1988-1992 Bushwick [Brooklyn, NY] Social Factors and HIV Risk (SFHR) Study, 1991-1993 Atlanta Urban Networks Project, 1996-1999 Flagstaff Rural Network Study, 1996-1998 Atlanta Antiretroviral Adherence Study, 1998-2001 Houston Risk Networks Study, 1997-1998 Baltimore SHIELD (Self-Help in Eliminating Life-Threatening Diseases), 1997-1999 Manitoba Chlamydia Study, 1997-1998 Each study contains information on sexual, needle sharing, and/or social networks. Each dataset was harmonized to permit comparative analysis. Almost all of the studies were research projects funded by federal agency sources (e.g., United States Centers for Disease Control and the National Institutes of Health); one was funded by Canadian sources. These studies, all closed for further enrollment, provide a range of designs and study types as well as a range of transmitted diseases. This allows researchers to investigate the relative effect of personal behavior and network connections on the dynamics of disease transmission, and to explore the impact of sampling design on estimation of network properties. Respondents were asked questions about different test results such as HIV, chlamydia, syphilis and hepatitis. Demographic variables include race, ethnicity, marital status, age, and gender.

Using a pragmatic trial design to limit exclusions, the investigators conducted a 36-month multi-center randomized effectiveness trial to compare the impact of an enhanced usual care (control) intervention, with exercise coaching (exercise), on fragility fractures and serious fall-related injuries (FF/SFRI) in patients with a previous fragility fracture. Specifically, the investigators examined the impact of the intervention on social loneliness, physical function, and bone strength. 1,139 individuals over 65 with a history of fragility fractures and/or osteoporosis were recruited over two years across three regions of Pennsylvania and randomized into either the enhanced usual care control group or exercise with coaching treatment group, where in-person exercise activities were led by trained volunteers. Dataset (DS) 1 contains the following data used for analysis: participant characteristics at baseline by study group (referred to as Table 5 in the documentation), intervention participant characteristics at baseline based on exercise session type (referred to as Table 6), cumulative incidences of first serious fall-related injury compared by study group (referred to as Figure 3), cumulative incidence for first serious fall-related injury by age, gender, race, and osteoporosis medication (referred to as Table 8 and Figure 4), and cumulative incidence for first series fall-related injury by tertile of average intervention sessions per month (referred to as Figure 5). Other datasets used for analysis are fall injury data (DS2), monthly workout sessions data (DS3), secondary outcomes data (DS4, referred to as Table 7), and adverse events data (DS5, referred to as Table 9). DS6 includes markers designating before and after the start of the COVID-19 pandemic (March 11, 2020), allowing for analyses of participants who experienced fall-related injuries relative to COVID-19. Datasets labeled "Miscellaneous" were not used in any analysis. These datasets contain extra measures from screening (DS7), baseline assessments (DS8), 4-month check-in visits (DS9), participant's distance to study site (DS10), coaching check-ins for weeks 1-12 (DS11), exercise sessions by month (DS12), adverse events (DS13), and end of study information (DS14).

The Japanese General Social Surveys (JGSS) Project is a Japanese version of the General Social Survey (GSS) project closely replicating the original GSS of the National Opinion Research Center at the University of Chicago. It provides data for analyses of Japanese society, attitudes, and behaviors, which makes possible international comparisons. Respondents were asked about employment, family and household composition, education, entertainment, technology and Internet usage, status and opinions on mental and physical health, alcohol and tobacco use, life satisfaction, addiction, proficiency with English, voting behavior, opinions on political and social issues, taxes and government expenditure, views on burial, family beliefs and issues, trust in people and institutions, membership in organizations, volunteering, perception of their personal appearance, receiving help from others, and their neighborhood environment. Demographic questions included age, sex, marital status, household income, and religious orientation and behavior.

The Korean General Social Survey (KGSS) is the South Korean version of the General Social Survey (GSS), closely replicating the original GSS of the National Opinion Research Center at the University of Chicago. Each round of the KGSS typically includes the topical module surveys of the International Social Survey Programme (ISSP), and/or the East Asian Social Survey (EASS), an international survey network of four GSS-type surveys from countries in East Asia (including China, Japan, Taiwan, and South Korea). Respondents were asked about their trust of people and institutions, government performance, health behaviors, chronic conditions, obstacles to obtaining health care, and physical pain. Additional questions were asked regarding family support, local issues, attitudes toward aging, addictive behaviors, environmental issues, and international migration. Demographic information includes age, sex, education level, household income, employment status, religious preference, political party affiliation, and political philosophy.

The Long Beach Longitudinal Study (LBLS) was created in 1978 to obtain normative data for the Schaie-Thurston Adult Mental Abilities Test (STAMAT). From 1994 to 2003 it was extended under the guiding principle that cognitive aging is a largely contextual phenomenon. Individual differences in abilities and change in those abilities over adulthood are associated not only with cognitive mechanisms, but with sociodemographic phenomena such as birth cohort, or gender, and within-individual characteristics, including health, affect, self-efficacy, personality, and other variables that impact health. This principle is reflected in the testing measures added to the original panel. Besides the original ability measures used by Schaie, the Life Complexity Inventory, has been included in all testing. Because these measures were included in the later generations of testing, independent and direct comparisons can be made with Seattle Longitudinal Study (ICPSR 00158) to replicate findings and to generalize longitudinal samples. Panel 1 The initial panel was sampled in 1978 and consisted of 65 adults aged 28-33 and 518 adults aged 55-84. This sample was tested using the STAMAT, as well as a 20-item list of common English nouns for testing free recall, and a brief essay to test text recall. In 1981, 264 participants from this sample were retested, 106 were again retested from 1994-1995, and 42 in 1997. Finally, 15 participants of the original sample were tested from 2000-2002 using additional tests adopted for the creation of a second panel, described below, as well as a test for measuring executive function. Panel 2 In 1994, a second panel of 630 participants aged 30-97, a third of which were over 80, was added to the study. The testing for this sample included multiple indices of list recall, text recall, working memory, perceptual speed, and vocabulary for structural equation modeling. Assessment of language, autobiographical memory, personality, depression, health, health behaviors and other measures were also incorporated into the study. In 1997, 352 members of this second panel were retested. From 2000-2002, 179 participants of this second panel completed the 1994-1995 measures, as well as several tests extending the battery to indices of executive function. In 2003, 133 participants were retested. Panel 3 A third sample was recruited during the 2000-2002 time frame consisting of 911 participants aged 30-98, again approximately a third of which were over the age of 80. In 2003, 513 members of this third panel were retested. Datasets The data are provided in 6 datasets. Panel 1 and 2 1978 - 2003 Longitudinal File Dataset 1 is a longitudinal file of data from Panel 1 for tests performed in 1978, 1981, 1994, 1997, and 2000-2002, and data from Panel 2 for tests performed in 1994, 1997, 2000-2002 and 2003. Panels 1 and 2 1994 STAMAT File Dataset 2 contains the STAMAT test variables for Panels 1 and 2. Panel 1 and 2 1994-2000 Master Data Longitudinal File Dataset 3 is a second longitudinal file containing the complete catalog of variables from Panels 1 and 2 for test performed in 1994, 1997 and 2000. Panel 2 Wave 1 1994 Cross File Dataset 4 contains variables for the first wave of Panel 2 which took place in 1,994. Panel 2 Wave 2 1997 Cross File Dataset 5 contains variables for the second wave of Panel 2 which took place in 1997. Panel 3 Wave 1 2000 Master File Dataset 6 contains variables from the first wave of Panel 3 which took place in 2000.

The Los Angeles Metropolitan Area Surveys [LAMAS] 8, 1974 collection reflects data gathered in 1974 as part of the Los Angeles Metropolitan Area Surveys (LAMAS). The LAMAS, beginning in the spring of 1970, are a shared-time omnibus survey of Los Angeles County community members, usually repeated twice annually. The LAMAS were conducted ten times between 1970 and 1976 in an effort to develop a set of standard community profile measures appropriate for use in the planning and evaluation of public policy. The LAMAS instruments, indexes, and scales were used to track the development and course of social indicators (including social, psychological, health, and economic variables) and the impact of public policy on the community. Questions in this survey cover respondents' attitudes toward the following topics: commute times, means of transportation, and trust in government. In addition, participating researchers were given the option of submitting questions to be asked in addition to the core items. These additional topics include: mental health and psychological factors, access to medical care, alcoholism, the energy crisis, and attitudes towards black-owned businesses. Demographic variables in this dataset include age, sex, marital status, ethnicity, education, income, occupation, political party affiliation, and language.

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.

The National Institute on Drug Abuse (NIDA) funded RADAR in 2014 to collect multilevel, longitudinal data and biospecimens from an ethnically and racially diverse cohort of young, sexual and gender minorities (SGM; e.g., men who have sex with men (MSM), transgender women, gender non-conforming individuals) who were assigned male at birth (AMAB) (current core cohort n=1,113). The primary objective of this study is to apply a multilevel perspective to a syndemic of health issues associated with human immunodeficiency virus (HIV) in this population. The multilevel design focuses on individual, dyadic (i.e., sexual and romantic relationships), network (i.e., social, drug, and sexual connections) and biologic factors that may be associated with HIV. The cohort contains both HIV-negative and HIV-positive individuals, which allows for the development of a repository of biospecimens and HIV sequence data from both pre-infection and post-infection visits that will help facilitate future projects evaluating substance use, HIV risk, and pathogenesis. A multiple cohort, accelerated longitudinal design was utilized by initially enrolling two existing SGM cohorts and then expanded through the use of convenience and snowball sampling methods. Enrollment criteria varied slightly based on the recruitment method, but overall inclusion criteria required participants to be AMAB, between 16 and 29 years of age, report having had sex with a man in the prior year or identify as a SGM, live in the Chicago metropolitan area, and be an English speaker. Study recruitment opened in February 2015. Participants are followed through the developmental period of late adolescence to early adulthood, which is a critical period of initiation and acceleration of sexual behavior and substance use. Study visits occur every six months.
