Black Rural and Urban Caregivers Mental Health/Functioning, Missouri, 1999-2002 (ICPSR 36349)

Released/updated on: 2019-01-28
Geographic coverage: United States, Missouri
Time period: 1999-01-01--2002-01-01

The Black Rural and Urban Caregivers Mental Health/Functioning data collection includes survey data collected in 2000-2002 from African American females age 65 and older, who provide unpaid care for older African American adults in the St. Louis Metropolitan area and seven rural Missouri counties (Butler, Dunklin, Mississippi, New Madrid, Pemiscot, Scott, and Stoddard).

Because of inadequate recruitment knowledge about rural African American caregivers and persistent reports of challenges when involving African Americans elders in research, this study focused on the involvement of African American rural elders and recruitment of their female informal caregivers in a study of caregivers' well-being and service use. African Americans comprise the largest group of ethnic and racial minority elders aged 65 and older in the U.S. population thus making up one half of all ethnic and racial minority elders. Numerical changes in population size and increasing longevity of older African Americans direct attention to African American informal female caregivers- persons most likely to assist African American elderly with daily living tasks, personal needs, and long-term care. More disabled and chronically ill African American elders portend continuing need from informal or unpaid caregivers for dependent care.

There are two datasets associated with this study, a public-use (da36349-0001) and restricted-use (da36349-0002) version of the same survey data. Both data files contain 521 cases and 1438 variables. However, the restricted file contains continuous as opposed to categorical values for age variables rounded to the nearest whole number.

Detroit Area Study, 1993: Health and Aging (ICPSR 2839)

Released/updated on: 2001-03-26
Geographic coverage: Detroit, United States, Michigan

The 1993 Detroit Area Study explored a variety of issues related to health, the effects of aging, living conditions, and participation in civic life in the Michigan tri-county area of Wayne, Oakland, and Macomb counties. A battery of questions probed respondents' perceptions of their health and mental state and those of their spouse, their ability to perform certain physical and mental activities, and the effect of their emotional state on their appetite and sleeping patterns. Other explored their feelings about neighborhood safety, means of transportation, relationships, accommodation, the portrayal of older people on television programs, and the treatment of older people by employers. The survey also sought respondents' opinions about government, their personal financial situation and problems, money management, savings and investments, and their life as a whole. Additional items questioned respondents about the frequency of their visits to the doctor, overnight hospitalization, chronic health conditions, smoking and drinking habits, and medical coverage, as well as electoral participation, political party preference, ideological leanings, class self-identification, assistance received from community organizations, family, and friends, personal regrets, and time spent watching television and engaging in pleasurable activities. Other questions gauged respondents' memory, vision, and motor skills. Respondents also provided demographic information on sex, age, marital status, race, ethnicity, religion, and education.

Health and Retirement Study (HRS) (ICPSR 6854)

Released/updated on: 2006-04-06
Geographic coverage: United States

The University of Michigan Health and Retirement Study (HRS) is a longitudinal panel study that surveys a representative sample of approximately 20,000 people in America, supported by the National Institute on Aging and the Social Security Administration.

The HRS aims to provide multidisciplinary data that researchers can use to address important questions about the challenges and opportunities of aging. The HRS includes the "original" HRS and the Asset and Health Dynamics Among the Oldest-Old (AHEAD) study. These studies were merged in 1998 and now represent the United States population over age 50. Two new cohorts were added in 1998: the Children of the Depression (born 1924-1930) and the War Babies (1942-1947). A fourth cohort, the Early Baby Boomers (1948-1953), was added in 2004; a fifth cohort, the Mid Baby Boomers (1954-1959), was added in 2010; and in 2016, the Late Baby Boomers cohort (1960-1965) became the sixth.

Questionnaire topics include physical and cognitive functioning, retirement plans, family structure and transfers, demographic characteristics, housing, employment status, income, disability, health insurance, pension plans, job history, and attitudes, preferences, and expectations for the future. The survey data are linked with administrative records from the Employer Pension Study (1993 and 1999), National Death Index, Social Security Administration earnings and projected benefits data and W-2 self-employment data, and Medicare files.

Hispanic Established Populations for Epidemiologic Studies of the Elderly (EPESE) Frailty Study: 2006-2009 (ICPSR 36321)

Released/updated on: 2016-03-29
Geographic coverage: United States, New Mexico, Texas, Colorado, California, Arizona
Time period: 2006-01-01--2009-01-01
The Hispanic Established Populations for Epidemiologic Studies of the Elderly (EPESE) Frailty Study sought to apply a standard definition of frailty in a well-defined sample of Mexican American older adults and to examine the impact of frailty on disability, health related quality of life, institutionalization, and mortality in this population over time. This project is a continuation of a prior study (the Hispanic EPESE) examining the enabling-disabling process in this same population of aging Mexican Americans; data were collected from 1,031 older adults who were participating in the Hispanic EPESE. Only subjects who were physically capable of safely completing the muscle strength measures were included. Baseline interviews were collected for this subsample in 2006/2007 during Wave 6 (ICPSR 29654) of the Hispanic EPESE study. This collection includes data about respondents' health status, activities of daily living and their ability to perform tasks. Two-year follow-up data were collected in 2008/2009 from 731 participants in Wave 1. Demographic and background information include age, relationship status, gender, marital status and household composition.

Marital Instability Over the Life Course [United States]: A Six-Wave Panel Study, 1980, 1983, 1988, 1992-1994, 1997, 2000 (ICPSR 3812)

Released/updated on: 2010-01-21
Geographic coverage: United States
Time period: 1992-01-01--1994-01-01
To examine the causes of marital instability throughout the life course, six waves of data were collected between 1980 and 2000 from married individuals who were between the ages of 18 and 55 in 1980. Information collected in 1980 (Wave I) focused on the effects of wives' participation in the labor force on marriage and marital instability. Measures predicting marital instability and divorce and assessing marital quality were developed. Variables include information on earnings, commitment to work, hours worked, and occupational status. The focus of Wave II, conducted in 1983, was to link changes in factors such as economic resources, wife's employment, presence of children, marital satisfaction, life goals, and health to actions intended to dissolve a marriage, such as divorce and permanent separation. Information on adjustment to marital dissolution, relationship with in-laws, size of home, parents' employment, use of free time, club membership, child-care arrangements, and responsibility for chores was gathered. Wave III, collected in 1988, further examined the impact of changes in employment, economics, and health on marital relationships. Questions were asked about divorce and remarriage, investment of energy and resource use in the care of aging parents and dependent offspring, asset value, awareness of aging, mental health issues, and history of disease. In 1992, Wave IV data were collected to look at changes in employment, economics, and health. Questions were asked about retirement issues, family structure, and the impact of caring for aging parents while at the same time caring for dependent offspring. Data were also collected in 1992 and 1994 from adult offspring who were living in the household in 1980 and had reached age 19 by 1992, thus providing parallel measures with their parents regarding the quality of parent-child relationships, attitudes, and support along with exploring the impact of childhood experiences on the transition to adult life. In 1997, the fifth wave was collected and interviews were conducted with a second sample of adult offspring (N=202) along with second interviews of offspring selected in 1992 (N=606). Wave V also examined the relationship between marital quality and stability and how it relates to changes in marital quality later in life. In 2000, Wave VI data were collected. Included with the adult panel was a panel obtained from the offspring who participated in 1992 or 1997, a replicate of the original cross-section study completed in 1980 (comprised of currently married persons between the ages of 19 and 55), along with a comparison sample made up of persons who were married in 1980 and were between 39 and 75 years old. The investigators examined whether there were changes in marital quality between 1980 and 2000, identified factors that might have accounted for these changes, and sought to determine their impact on the health and longevity of older persons. New questions included in Wave VI covered whether the respondent thought he/she had an organized lifestyle, alcohol and tobacco use, health problems, physical limitations, and mattering (the level of concern expressed for and received from spouse). Among the variables included in all six waves are age, sex, educational attainment, marital status and history, attitude toward divorce, number of children, religious affiliation, and income level. The Work and Family Life Study (ICPSR 26641) was conducted in 2000 as a follow-up to the Marital Instability Over the Life Course Study. Included in the Work and Family Life Study is a new cross-section of 2,100 married people 55 years of age and younger. Additionally, the Work and Family Life Study contains a Comparison Sample comprised of 1,600 additional respondents. The purpose of this Comparison Sample is to assess potential bias due to sample attrition in the panel study.

National Health and Nutrition Examination Survey (NHANES), 1999-2000 (ICPSR 25501)

Released/updated on: 2012-02-22
Geographic coverage: United States
Time period: 1999-01-01--2000-01-01
The National Health and Nutrition Examination Surveys (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The NHANES combines personal interviews and physical examinations, which focus on different population groups or health topics. These surveys have been conducted by the National Center for Health Statistics (NCHS) on a periodic basis from 1971 to 1994. In 1999 the NHANES became a continuous program with a changing focus on a variety of health and nutrition measurements which were designed to meet current and emerging concerns. The surveys examine a nationally representative sample of approximately 5,000 persons each year. These persons are located in counties across the United States, 15 of which are visited each year. The 1999-2000 NHANES contains data for 9,965 individuals (and MEC examined sample size of 9,282) of all ages. Many questions that were asked in NHANES II, 1976-1980, Hispanic HANES 1982-1984, and NHANES III, 1988-1994, were combined with new questions in the NHANES 1999-2000. The 1999-2000 NHANES collected data on the prevalence of selected chronic conditions and diseases in the population and estimates for previously undiagnosed conditions, as well as those known to and reported by respondents. Risk factors, those aspects of a person's lifestyle, constitution, heredity, or environment that may increase the chances of developing a certain disease or condition, were examined. Data on smoking, alcohol consumption, sexual practices, drug use, physical fitness and activity, weight, and dietary intake were collected. Information on certain aspects of reproductive health, such as use of oral contraceptives and breastfeeding practices, were also collected. The interview includes demographic, socioeconomic, dietary, and health-related questions. The examination component consists of medical, dental, and physiological measurements, as well as laboratory tests. Demographic data file variables are grouped into three broad categories: (1) Status Variables: Provide core information on the survey participant. Examples of the core variables include interview status, examination status, and sequence number. (Sequence number is a unique ID assigned to each sample person and is required to match the information on this demographic file to the rest of the NHANES 1999-2000 data). (2) Recoded Demographic Variables: The variables include age (age in months for persons through age 19 years, 11 months; age in years for 1-84 year olds, and a top-coded age group of 85+ years), gender, a race/ethnicity variable, an education variable (high school, and more than high school education), country of birth (United States, Mexico, or other foreign born), and pregnancy status variable. Some of the groupings were made due to limited sample sizes for the two-year dataset. (3) Interview and Examination Sample Weight Variables: Sample weights are available for analyzing NHANES 1999-2000 data.

The 2001-2002 NHANES contains data for 11,039 individuals (and MEC examined sample size of 10,477) of all ages. Many questions that were asked in NHANES II, 1976-1980, Hispanic HANES 1982-1984, and NHANES III, 1988-1994, were combined with new questions in the NHANES 2001-2002. As in past health examination surveys, data were collected on the prevalence of chronic conditions in the population. Estimates for previously undiagnosed conditions, as well as those known to and reported by survey respondents, are produced through the survey. Risk factors, those aspects of a person's lifestyle, constitution, heredity, or environment that may increase the chances of developing a certain disease or condition, were examined. Data on smoking, alcohol consumption, sexual practices, drug use, physical fitness and activity, weight, and dietary intake were collected. Information on certain aspects of reproductive health, such as use of oral contraceptives and breastfeeding practices, were also collected. The diseases, medical conditions, and health indicators that were studied include: anemia, cardiovascular disease, diabetes and lower extremity disease, environmental exposures, equilibrium, hearing loss, infectious diseases and immunization, kidney disease, mental health and cognitive functioning, nutrition, obesity, oral health, osteoporosis, physical fitness and physical functioning, reproductive history and sexual behavior, respiratory disease (asthma, chronic bronchitis, emphysema), sexually transmitted diseases, skin diseases, and vision. The sample for the survey was selected to represent the United States population of all ages. Special emphasis in the 2001-2002 NHANES was on adolescent health and the health of older Americans. To produce reliable statistics for these groups, adolescents aged 15-19 years and persons aged 60 years and older were over-sampled for the survey. African Americans and Mexican Americans were also over-sampled to enable accurate estimates for these groups. Several important areas in adolescent health, including nutrition and fitness and other aspects of growth and development, were addressed. Since the United States has experienced dramatic growth in the number of older people during the twentieth century, the aging population has major implications for health care needs, public policy, and research priorities. NCHS is working with public health agencies to increase the knowledge of the health status of older Americans. NHANES has a primary role in this endeavor. In the examination, all participants visit the physician who takes their pulse or blood pressure. Dietary interviews and body measurements are included for everyone. All but the very young have a blood sample taken and see the dentist. Depending upon the age of the participant, the rest of the examination includes tests and procedures to assess the various aspects of health listed above. Usually, the older the individual, the more extensive the examination. Some persons who are unable to come to the examination center may be given a less extensive examination in their homes. Demographic data file variables are grouped into three broad categories: (1) Status Variables: provide core information on the survey participant. Examples of the core variables include interview status, examination status, and sequence number. (Sequence number is a unique ID assigned to each sample person and is required to match the information on this demographic file to the rest of the NHANES 2001-2002 data).

The National Health and Nutrition Examination Surveys (NHANES) is a program of studies designed to assess the health and nutritional status of adults and children in the United States. The NHANES combines personal interviews and physical examinations, which focus on different population groups or health topics. These surveys have been conducted by the National Center for Health Statistics (NCHS) on a periodic basis from 1971 to 1994. In 1999 the NHANES became a continuous program with a changing focus on a variety of health and nutrition measurements which were designed to meet current and emerging concerns. The surveys examine a nationally representative sample of approximately 5,000 persons each year. These persons are located in counties across the United States, 15 of which are visited each year. For NHANES 2007-2008, there were 12,946 persons selected for the sample, 10,149 of those were interviewed (78.4 percent) and 9,762 (75.4 percent) were examined in the mobile examination centers (MEC). Many of the NHANES 2007-2008 questions were also asked in NHANES II 1976-1980, Hispanic HANES 1982-1984, NHANES III 1988-1994, and NHANES 1999-2006. New questions were added to the survey based on recommendations from survey collaborators, NCHS staff, and other interagency work groups. As in past health examination surveys, data were collected on the prevalence of chronic conditions in the population. Estimates for previously undiagnosed conditions, as well as those known to and reported by survey respondents, are produced through the survey. Risk factors, those aspects of a person's lifestyle, constitution, heredity, or environment that may increase the chances of developing a certain disease or condition, were examined. Data on smoking, alcohol consumption, sexual practices, drug use, physical fitness and activity, weight, and dietary intake were collected. Information on certain aspects of reproductive health, such as use of oral contraceptives and breastfeeding practices, were also collected. The diseases, medical conditions, and health indicators that were studied include: anemia, cardiovascular disease, diabetes and lower extremity disease, environmental exposures, equilibrium, hearing loss, infectious diseases and immunization, kidney disease, mental health and cognitive functioning, nutrition, obesity, oral health, osteoporosis, physical fitness and physical functioning, reproductive history and sexual behavior, respiratory disease (asthma, chronic bronchitis, emphysema), sexually transmitted diseases, skin diseases, and vision. The sample for the survey was selected to represent the United States population of all ages. The NHANES target population is the civilian, noninstitutionalized United States population. Beginning in 2007, some changes were made to the domains being oversampled. The primary change is the oversampling of the entire Hispanic population instead of just the Mexican American (MA) population, which has been oversampled since 1988. Sufficient numbers of MAs were retained in the sample design so that trends in the health of MAs can continue to be monitored. Persons 60 years of age and older, Blacks, and low income persons were also oversampled. In addition, for each of the race/ethnicity domains, the 12-15 and 16-19 year age domains were combined and the 40-59 year age minority domains were split into 10-year age domains of 40-49 and 50-59. This has led to an increase in the number of participants aged 40 and older and a decrease in 12- to 19-year-olds from previous cycles. The oversample of pregnant women and adolescents in the survey from 1999-2006 was discontinued to allow for the oversampling of the Hispanic population. NCHS is working with public health agencies to increase knowledge of the health status of older Americans. NHANES has a primary role in this endeavor. In the examination, all participants visit the physician who takes their pulse or blood pressure. Dietary interviews and body measurements are included for everyone. All but the very young have a blood sample taken and see the dentist. Depending upon the age of the participant, the rest of the examination includes tests and procedures to assess the various aspects of health listed above. Usually, the older the individual, the more extensive the examination. Demographic data file variables are grouped into three broad categories: (1) Status Variables: Provide core information on the survey participant. Examples of the core variables include interview status, examination status, and sequence number. (Sequence number [SEQN] is a unique ID number assigned to each sample person and is required to match the information on this demographic file to the rest of the NHANES 2007-2008 data.) (2) Recoded Demographic Variables: The variables include age (age in months for persons under age 80, age in years for 1 to 80-year-olds, and a top-coded age group of 80 years and older), gender, a race/ethnicity variable, an current or highest grade of education completed, (less than high school, high school, and more than high school education), country of birth (United States, Mexico, or other foreign born), ratio of family income to poverty threshold, income, and a pregnancy status variable (adjudicated from various pregnancy-related variables). Some of the groupings were made due to limited sample sizes for the two-year dataset. (3) Interview and Examination Sample Weight Variables: Sample weights are available for analyzing NHANES 2007-2008 data. Most data analyses require either the interviewed sample weight (variable name: WTINT2YR) or examined sample weight (variable name: WTMEC2YR). The two-year sample weights (WTINT2YR, WTMEC2YR) should be used for NHANES 2007-2008 analyses.

National Health Interview Survey: Longitudinal Study of Aging, 70 Years and Over, 1984-1990 (ICPSR 8719)

Released/updated on: 2011-08-18
Geographic coverage: United States
Time period: 1984-01-01--1990-01-01
This study, commonly known as the Longitudinal Study of Aging (LSOA), was conducted by the National Center for Health Statistics (NCHS) in collaboration with the National Institute on Aging (NIA) and designed to (1) provide mortality rates by demographic, social, economic, and health characteristics that are not available from the vital statistics system, (2) measure change in the functional status and living arrangements of older people, and (3) provide measures of health care use. It was also designed to describe the continuum from functionally independent living in the community through dependence, possible institutionalization, and finally death. The LSOA is an extension of the National Health Interview Survey (NHIS) of 1984, following its sample of 16,148 noninstitutionalized elderly people (55 years and over) living in the United States, with a special focus on those who were 70 years and over in 1984. This release of the LSOA contains data on those respondents who had been 70 years and older at the time of their 1984 interviews. The data include 1986, 1988, and 1990 reinterviews, National Death Index matches from 1984-1989, and 1987 interviews with contact persons named by decedents, as well as selected variables from the 1984 NHIS core questionnaire and its two supplements, Health Insurance and the Supplement on Aging (SOA). Two Medicare files are also included: Part 2, Medicare Hospital Records, and Part 3, Other Medicare Use Records (which covers home health care, hospice, and outpatient use). Links also are provided to allow merging of additional variables from the NATIONAL HEALTH INTERVIEW SURVEY, 1984 (ICPSR 8659).

National Survey of the Aged, 1975 (ICPSR 7945)

Released/updated on: 1992-02-16
Geographic coverage: United States
This survey was conducted during the spring and summer of 1975 under a grant from the Administration on Aging and with supplemental funding from the Social Security Administration. It surveyed noninstitutionalized Americans aged 65 and older with a special focus on developing national estimates of the economic needs and social concerns of the elderly. The survey attempted to describe the aged population and to indicate the degree of health, financial independence, and familial support of 2,143 older Americans. Also studied were the work status of respondents, their past and present attitudes toward work, their desire for gainful employment, their income and assets, their evaluation of their own financial status, and their reported use of health and welfare services. The data collection comprises three files. Part 1 contains the general survey, Part 2 is a survey of proxy respondents, and Part 3 supplies information on persons who could not complete an interview.

National Survey of the Aged [United States], 1957 (ICPSR 7686)

Released/updated on: 2006-03-30
Geographic coverage: United States
This survey, sponsored by the Health Information Foundation at the University of Chicago and conducted at the National Opinion Research Center, consists of three component parts. Part 1, the Health Needs of Older Persons, covers health, the use of medical facilities, the cost of medical care, the older person's sources of income, his/her social relationships, attitudes toward younger family members, work, religion, and a self-evaluation of health status for persons aged 60 and over. Part 2, Household Enumeration: Noninterviewed Individuals, contains information describing persons located during the enumeration process who were unable to complete an interview. For Part 3, Public Attitudes on Older People, a cross-section of adult Americans was surveyed. This survey was mainly concerned with the level of responsibility younger and middle-aged people assumed for older relatives, the kinds of plans they were making for their own maintenance in later years, and overall attitudes on the part of all age groups toward certain situations that are commmon in later life.

National Survey of the Aged [United States], 1962 (ICPSR 7687)

Released/updated on: 1992-02-16
Geographic coverage: United States
This data collection contains the results of a survey of the aged in the United States in 1962. The study gathered information on the health, economic status, living arrangements, and family relationships of persons aged 65 years and older. The emphasis of the survey was on the general physical capacity of older people, the relationship of physical capacity to economic conditions, employment and retirement patterns, housing, and family and social relationships. The survey was designed to produce national estimates of the needs of older persons. In particular, the services that facilitate continued independent living arrangements were examined. The survey was conducted by the National Opinion Research Center and was part of a three-nation study in Denmark, Great Britain, and the United States (see NATIONAL SURVEY OF THE AGED [UNITED STATES], 1957 [ICPSR 7686] and NATIONAL SURVEY OF THE AGED, 1975 [ICPSR 7945]). In personal interviews respondents who were currently employed (and those who were retired or housewives) were asked for employment details and occupational history, their attitudes about work and retirement, and descriptions of their physical health, with specific questions asked of both nonambulatory and housebound persons, (e.g., if they needed and/or received help with various personal care tasks, what specific illness kept them indoors, and who provided their in-home care). Respondents were also asked for information about their children and relatives (e.g., the amount of financial help received from them, the number of times each sibling and child visited, and the amount of time it would take each to make the trip to the respondent's dwelling) and their finances (e.g., living expenses, life insurance, value of property, amount of mortgage payment or rent, and amount and sources of income). Other questions concerned attitudes about aging (e.g., if respondents were satisfied with their life accomplishments, if they believed in an afterlife, and how often they experienced feelings of loneliness and isolation). The interviewers provided observational data about respondents (e.g., level of cooperation and alertness and ability to hear and see). Demographic data gathered include age, sex, marital status, relationship to head of household, number of persons in household, type of household, country of origin, age when arrived in the United States, last grade or year of school completed, religious preference, and if living on a farm.

New York City Health and Nutrition Examination Survey (NYC HANES), 2004 (ICPSR 31421)

Released/updated on: 2011-11-03
Geographic coverage: New York City, United States, New York (state)
Time period: 2004-06-02--2004-12-19
The New York City Department of Health and Mental Hygiene, with support from the National Center for Health Statistics, conducted the New York City Health and Nutrition Examination Survey (NYC HANES) to improve disease surveillance and establish citywide estimates for several previously unmeasured health conditions from which reduction targets could be set and incorporated into health policy planning initiatives. NYC HANES also provides important new information about the prevalence and control of chronic disease precursors, such as undiagnosed hypertension, hypercholesterolemia, and impaired fasting glucose, which allow chronic disease programs to monitor more proximate health events and rapidly evaluate primary intervention efforts. Study findings are used by the public health community in New York City, as well as by researchers and clinicians, to better target resources to the health needs of the population. The NYC HANES data consist of the following six datasets: (1) Study Participant File (SPfile), (2) Computer-Assisted Personal Interview (CAPI), (3) Audio Computer-Assisted Self-Interview (ACASI), (4) Composite International Diagnostic Interview(CIDI), (5) Examination Component, and (6) Laboratory Component. The Study Participant File contains variables necessary for all analyses, therefore, when using the other datasets, they should be merged to this file. Variable P_ID is the unique identifier used to merge all datasets. Merging information from multiple NYC HANES datasets using SP_ID ensures that the appropriate information for each SP is linked correctly. (SAS datasets must be sorted by SP_ID prior to merging.) Please note that NYC HANES datasets may not have the same number of records for each component because some participants did not complete each component. Demographic variables include race/ethnicity, Hispanic origin, age, body weight, gender, education level, marital status, and country of birth.

Old Age in the United States, 1880 (ICPSR 8427)

Released/updated on: 1992-10-31
Geographic coverage: United States
This data collection describes the social conditions of the older population of the United States in the late nineteenth century. Variables include personal characteristics such as age, sex, marital status, race, birthplace, number of children, and occupation of sampled older persons. Detailed information, extracted from the 1880 United States Census manuscript census schedules, is provided on household composition and family structure. In addition, occupational and ethnic characteristics of family heads appearing on the same sampled census page as the older person (on census pages grouped by street location) are reported. The data collection consists of three independent samples: (1) a national sample, (2) a Southern urban sample, and (3) a Southern Black sample. Older Blacks are over-represented in the Southern urban and Southern Black samples in order to focus on their family experiences in the urban and rural South.

Stroke Recovery in Underserved Populations 2005-2006 [United States] (ICPSR 36422)

Released/updated on: 2016-05-03
Geographic coverage: United States
Time period: 2005-01-01--2006-01-01

The Stroke Recovery in Underserved Populations 2005-2006 study was created to address the National Institute on Aging (NIA) Request For Application entitled "Research on Mind-Body Interactions and Health" (RFA OD-03-008). It addressed the NIA interest in "the impact of optimism, happiness, or a positive attitude on well-being and health; and social functioning and health." The study examined how positive emotion (e.g., joy, gratitude, love, contentment) and social networks independently and interactively contribute to recovery of functional status after stroke within two underserved groups. The specific study aims were to:

  1. Examine recovery of functional status (motor and cognitive function), for White, African American and Hispanic persons with stroke discharged from rehabilitation facilities
  2. Examine the contributions of positive emotion and social networks on recovery of functional status (motor and cognitive function), for White, African American, and Hispanic persons with stroke discharged from rehabilitation facilities; and
  3. Examine the interaction between positive emotion and social networks on recovery of functional status (motor and cognitive function) for White, African American, and Hispanic persons with stroke discharged from rehabilitation facilities.

The data were collected by the IT Health Track at four time points: at admission and discharge from rehabilitation facility, and 80-180 days and 365-425 days after discharge. These data emphasize recovery of motor and cognitive functional status, positive emotion, and social networks

The dataset contains 226 variables and 1219 cases from 11 rehabilitation facilities across the United States.

Work and Family Life Study [United States] (ICPSR 26641)

Released/updated on: 2010-01-26
Geographic coverage: United States
Time period: 1992-01-01--1994-01-01

Formerly titled Marital Instability Over the Life Course (MIOLC -- ICPSR 3812), the Work and Family Life Study (WFLS) is a follow-up to the MIOLC. The MIOLC examined the causes of marital instability throughout the life course, and contains 6 waves of data collected between 1980 and 2000, which were gathered from married respondents who were between the ages of 19 and 55.

The Work and Family Life Study provides data for use in assessing: changes in marital quality between 1980 and 2000; the effects of family-of-origin characteristics and marital history on the physical and psychological health of respondents; and evaluating sample attrition, factors which lead to attrition, and attrition bias.

The WFLS collected new cross-sectional information (Part 2 -- Public Use Cross Section, N = 2,189) on married people 55 years of age and younger, using the same sampling procedures and interview questions that were used in the 1980 wave of the MIOLC. The Work and Family Life Study's Public Use Cross Section is the latest addition to the data collections. This new Public Use Cross Section studies the effects of wives' participation in the labor force on marriage and marital instability.

Also provided in this collection are the Public Use All Waves (Part 1, N = 2,034) and the Public Use Panel Wave 6 (Part 3, N = 1,031). The Public Use All Waves contains information from Waves I through VI, which were collected in 1980, 1983, 1987, 1992-1994, 1997, and 2000. Among the variables included in all six waves are age, sex, educational attainment, marital status and history, attitude toward divorce, number of children, religious affiliation, and income level. The Public Use Panel Wave 6 contains data on persons who only responded to wave 6 of the study.

Unique to this data collection, the Public Use Comparison file (Part 4, N = 11,741) contains information on respondents who would have been between the ages of 19 and 55 in 1980, married, and living with their spouse. These data evaluate potential bias from sample attrition in the panel study. The Comparison Sample is a special purpose sample and does not generalize to a normally defined population of ever married persons.
