Center for Research on Social Reality [Spain] Survey, May 1995: Old Age (ICPSR 6969)

Released/updated on: 1998-01-13

Geographic coverage: Europe, Global, Spain

Time period: 1995-05-15--1995-05-20

This data collection is part of a series of nationwide surveys conducted from October 1990 to June 1996 in Spain. The questionnaires for each of these surveys consisted of three sections. The first section collected information on respondents' attitudes regarding personal, national, and international issues, and included questions on respondents' level of life satisfaction and frequency of visits with relatives, neighbors, and friends. The second section contained a topical module of questions that varied from survey to survey, with this survey's topic focusing on old age. The survey gauged attitudes regarding old age and the elderly, and investigated actual circumstances of elderly life in Spain, such as living arrangements, daily levels of physical activity, amount of health problems experienced during the past two weeks, consumption of tobacco and alcohol, frequency of sexual relations, retirement status and age at retirement, leisure activities, and use of social services. Questions in the third section of the questionnaire elicited socioeconomic information, such as respondent's sex, age, marital status, size of household, occupation, education, religion, religiosity, place of birth, and income.

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

Released/updated on: 2001-03-26

Geographic coverage: Detroit, United States, Michigan

Time period: 1993-01-01--1993-12-31

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.

Euro-barometer 34.1: Health Problems, Fall 1990 (ICPSR 9577)

Released/updated on: 2001-02-01

Geographic coverage: Europe, United Kingdom, Portugal, Global, Spain, Greece, Netherlands, Belgium, Luxembourg, Ireland, Denmark, Italy, France, Germany

Time period: 1990-10-16--1990-11-27

This round of Euro-Barometer surveys queried respondents on standard Euro-Barometer measures, such as how satisfied they were with their present life, whether they attempted to persuade others close to them to share their views on subjects they held strong opinions about, whether they discussed political matters, what their country's goals should be for the next ten or fifteen years, and how they viewed the need for societal change. The surveys also focused on health problems. Questions about smoking examined whether the respondent had heard of the European Code Against Cancer and whether the respondent smoked. Smokers were asked what tobacco products they used, how many cigarettes they smoked in a day, and whether they planned to cut down on their tobacco consumption. Queries focusing on other health issues included respondents' subjective ratings of their health and diet, the basis for their foodstuff selections, the extent and impact of alcohol consumption on their driving, the extent of the problem of drinking and driving, how the problem of drinking and driving would be best addressed, and respondents' own use of alcohol. Opinions on alcohol and drug abuse were elicited through questions such as what type of problem the respondent considered alcohol and drug use to be, whether current measures were enough to solve abuse, what measures should be taken to solve the problems, the respondent's knowledge of drugs and the use of drugs, drug use among acquaintances, and how drug testing should be implemented. AIDS-related items focused on how the respondent thought AIDS could be contracted and which manner of transmission the respondent most feared, which interventions should be used to eliminate or to slow the spread of AIDS, which interventions should be undertaken by the European Community, how best to handle those who had AIDS or were HIV-positive, whether the respondent personally knew anyone with AIDS/HIV+, how the emergence and spread of AIDS had changed the respondent's personal habits, and what precautions were effective against contracting AIDS. Questions concerning the respondent's work history asked whether there had been periods without work lasting more than a year. A series of items focused on the longest period without pay: how long the period was, the age of the respondent during this period, the main reason for leaving the previous job, what the previous occupation was and whether it was part-time, what the new occupation was and whether it was part-time, and how the level of the new occupation compared to the previous occupation. The interaction of raising children and pursuing a career was investigated through questions including how many children the respondent had, what effect changes in family life had on working life, whether the respondent worked full- or part-time while raising children, and whether the respondent would prefer to care for children full-time, care for children part-time and work part-time, or work full-time. A series of questions pertained to the period prior to the respondent's first three children attending school: whether the respondent worked during this period, what the respondent's occupation was, the attributes of the occupation that concerned the family, the attributes of the partner's occupation that concerned the family, who the primary caregivers were, whether the partner was the primary caregiver, and whether there were difficulties making last-minute arrangements for child care. Additional information was gathered on family income, number of people residing in the home, size of locality, home ownership, region of residence, occupation of the head of household, and the respondent's age, sex, occupation, education, religion, religiosity, subjective social class standing, political party and union membership, and left-right political self-placement.

Released/updated on: 2000-09-25

Geographic coverage: Europe, United Kingdom, Portugal, Global, Spain, Greece, Netherlands, Belgium, Luxembourg, Ireland, Denmark, Italy, France, Germany

Time period: 1992-03-01--1992-05-31

This dataset merges the responses to identical questions from two waves of Euro-Barometer surveys, EURO-BAROMETER 37.0: AWARENESS AND IMPORTANCE OF MAASTRICHT AND THE FUTURE OF THE EUROPEAN COMMUNITY, MARCH-APRIL 1992 (ICPSR 9847), and EURO-BAROMETER 37.1: CONSUMER GOODS AND SOCIAL SECURITY, APRIL-MAY 1992 (ICPSR 9957). These surveys queried respondents on standard Euro-Barometer measures such as public awareness of and attitudes toward the Common Market and the European Community (EC), and also focused on alcohol and drug use. Items covered the use of beer, wine, spirits, and other forms of alcohol, age at which the respondent began drinking, familiarity with major forms of drugs, age at which drugs were first offered, how difficult it was to get drugs, and the means available for getting drugs. Additional questions focused on how the respondent viewed the drug problem, the top priority in eliminating the drug problem, diminishing the effects of drug use, and whether drug use leads to AIDS, prostitution, health problems, social problems, violence, suicide, personality breakdowns, and problems with the law. Respondents were also asked for their opinions on several measures used to combat the effects of drug use and the major reasons for alcohol and drug use. Demographic and other background information was gathered on the number of people residing in the home, size of locality, home ownership, trade union membership, region of residence, and occupation of the head of household, as well as the respondent's age, sex, marital status, education, occupation, work sector, religiosity, subjective social class, left-right political self-placement, and opinion leadership.

Euro-barometer 37.1: Consumer Goods and Social Security, April-May 1992 (ICPSR 9957)

Released/updated on: 2000-09-25

Geographic coverage: United Kingdom, Portugal, Global, Spain, Greece, Netherlands, Belgium, Luxembourg, Ireland, Denmark, Italy, France, Germany

Time period: 1992-04-20--1992-05-24

This round of Euro-Barometer surveys queried respondents on standard Euro-Barometer measures such as public awareness of and attitudes toward the Common Market and the European Community (EC), and also focused on consumer goods, Social Security, health care and health care benefits, the elderly, retirement, and alcohol and drug use. Questions concerning consumer goods asked whether respondents read product information before purchasing, what additional product information they would like to see, what three things other than price were most important in deciding whether to purchase an item, and whether it was necessary to have the same type of product information available for all members of the European Community (EC). Respondents' attitudes and opinions on Social Security were probed with questions that asked whether they agreed that Social Security properly protects the unemployed, the elderly, the sick or disabled, those with work-related injuries or illness, and the poor. Respondents were also asked whether policies on pensions, minimum income, and unemployment should be decided by national governments or by the EC, and whether foreigners should have the same Social Security benefits as citizens. The general health of respondents and their health care benefits were assessed through questions that asked whether they had a long-standing illness, disability, or infirmity, whether they had cut down their activity due to illness or injury, and whether they had taken medicine or talked to a doctor within the last 30 days. Respondents were also queried about which conditions they would see a doctor for and what type of examinations they had had in the past three years. Respondents were asked to rate what they paid for various medical services, the general quality of their health care, and the nature and availability of health insurance. The main problems facing the elderly and the role the elderly play in society were also topics of investigation in this survey. Questions elicited respondents' views toward possible changes in pension terms, whether retirement should occur at a fixed age, what types of discrimination affect the elderly who are working, whether the government should introduce laws to try to stop age discrimination, whether a minimum level of income should be provided to the elderly, and whether the elderly needing personal care should go into residential/nursing homes or should have social services help them remain in their homes for as long as possible. Respondents were also asked whether they provided long-term care to anyone either living with them or not living with them, who was in the best position to decide which services are most important for the elderly, what the best method of financing long-term care for the elderly was, and whether the EC was doing enough with regard to the elderly. Questions on retirement dealt with what ages respondents retired/planned to retire, whether the retired felt their pensions to be adequate, whether working people looked forward to retiring, whether pensions should be extended to widows and dependent children, whether pensions should be reduced for those who work for earned income beyond retirement, and whether pensions should be provided through government taxation, employer/employee contributions, or private contracts between workers and pension companies. Queries about alcohol and drug usage probed the use of beer, wine, spirits, and other forms of alcohol, age at which the respondent began drinking, familiarity with major forms of drugs, age at which drugs were first offered, how difficult it was to get drugs, and the means available for getting drugs. Additional questions focused on how the respondent viewed the drug problem, the top priority in eliminating the drug problem, diminishing the effects of drug use, whether drug use leads to AIDS, prostitution, health problems, social problems, violence, suicide, personality breakdowns, and problems with the law, and the major reasons for alcohol and drug use. Demographic and other background information was gathered on life satisfaction, number of people residing in the home, size of locality, home ownership, trade union membership, region of residence, and occupation of the head of household, as well as the respondent's age, sex, marital status, education, occupation, work sector, religiosity, subjective social class, use of media, left-right political self-placement, and opinion leadership.

High School and Beyond, 1980: Sophomore and Senior Cohort Third Follow-up (1986) (ICPSR 8896)

Released/updated on: 2014-01-21

Geographic coverage: United States

Time period: 1986-01-01--1986-12-31

This data collection represents the fourth wave of the High School and Beyond series. The base-year data (ICPSR 7896) were collected in 1980, and the first and second follow-ups (ICPSR 8297 and ICPSR 8443) were conducted in 1982 and 1984. The High School and Beyond series is a longitudinal study of students who were high school sophomores and seniors in 1980. As with the first and second follow-ups, the structure and documentation of High School and Beyond Third Follow-Up data files represent a departure from base-year (1980) practices. While the base-year student file contains data from both the senior and sophomore cohorts, the three follow-up surveys provide separate student files for the two cohorts. Each of the cohort files for this collection merges the base year and first and second follow-up data with the third follow-up data. To maintain comparability with prior waves, many questions from previous follow-up surveys were repeated on the third follow-up questionnaire. Respondents were asked to update background information and to provide information about their work experience, unemployment history, education and other training, family information, income, and other experiences and opinions. Event history formats were used for obtaining responses about jobs held, schools attended, periods of unemployment, and marriage patterns. New items were added on respondents' interest in graduate degree programs and on alcohol consumption habits. The transcript files, which present data taken from official records of academic and vocational schools, include information on program enrollments, periods of study, fields of study pursued, specific courses taken, and credentials earned.

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: 1980-01-01--1980-12-31, 1983-01-01--1983-12-31, 1988-01-01--1988-12-31, 1992-01-01--1994-12-31, 1997-01-01--1997-12-31, 2000-01-01--2000-12-31

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.

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 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). (2) Recoded Demographic Variables: these 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 of age and older), gender, a race/ethnicity variable, 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), Poverty Income Ratio (PIR), 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 data set. (3) Interview and Examination Sample Weight Variables: sample weights are available for analyzing NHANES 2001-2002 data.

For NHANES 2003-2004, there were 12,761 persons selected for the sample, 10,122 of those were interviewed (79.3 percent) and 9,643 (75.6 percent) were examined in the mobile examination centers (MEC). Many of the NHANES 2003-2004 questions were also asked in NHANES II 1976-1980, Hispanic HANES 1982-1984, NHANES III 1988-1994, and NHANES 1999-2002. New questions were added to the survey based on recommendations from survey collaborators, NCHS staff, and other interagency work groups.

For NHANES 2005-2006, there were 10,348 persons selected for the sample, 10,122 of those were interviewed (79.3 percent) and 9,643 (75.6 percent) were examined in the mobile examination centers (MEC). Many of the NHANES 2005-2006 questions were also asked in NHANES II 1976-1980, Hispanic HANES 1982-1984, NHANES III 1988-1994, and NHANES 1999-2004. 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. Special emphasis in the 2005-2006 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 or unwilling 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 2005-2006 data). (2) Recoded Demographic Variables: these variables include age (age in months for persons through age 19 years, 11 months; age in years for 1- to 84-year-olds, and a top-coded age group of 85 years of age and older), gender, a race/ethnicity variable, 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), Poverty Income Ratio (PIR), 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 2005-2006 data.

National Health and Nutrition Examination Survey (NHANES), 2007-2008 (ICPSR 25505)

Released/updated on: 2012-02-22

Geographic coverage: United States

Time period: 2007-01-01--2008-12-31

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.

Geographic coverage: United States

Time period: 1985-01-01--1985-12-31

The basic purpose of the National Health Interview Survey is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. There are five types of records in the core survey, each in a separate data file. The variables in the Household File (Part 1) include type of living quarters, size of family, number of families in household, and geographic region. The variables in the Person File (Part 2) include sex, age, race, marital status, veteran status, education, income, industry and occupation codes, and limits on activity. These variables are found in the Condition, Doctor Visit, and Hospital Episode Files as well. The Person File also supplies data on height, weight, bed days, doctor visits, hospital stays, years at residence, and region variables. The Condition (Part 3), Doctor Visit (Part 4), and the Hospital Episode (Part 5) Files contain information on each reported condition, two-week doctor visit, or hospitalization (twelve-month recall), respectively. A sixth, seventh, and eighth file have been added along with the five core files. The Health Promotions and Disease Prevention Supplement is separated into three categories as follows: Child Safety/Infant Feeding (Part 6), Sample Person (Part 7), and Smoking (Part 8). These data files include questions on health and fitness awareness, general health habits, injury control, child safety and health, high blood pressure, stress, exercise, smoking, alcohol use, dental care, and occupational safety and health.

The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. In 1985, the NHIS questionnaire included a special section, the Health Promotions and Disease Prevention (HPDP) supplement, that queried female respondents aged 18 through 44 who had had live births in the past five years about smoking during pregnancy. Their responses to the supplement are recorded in this dataset, along with other information about them derived from the HPDP and the 1985 core questionnaire (see HEALTH INTERVIEW SURVEY, 1985 [ICPSR 8668]). Questions on smoking history during pregnancy included current pregnancy status, whether the respondent had ever smoked 100 cigarettes, whether she currently smoked, time elapsed since the respondent last smoked regularly, number of cigarettes the respondent smoked per day, whether the respondent smoked during pregnancy, number of cigarettes smoked before learning of pregnancy, number of cigarettes smoked after learning of pregnancy, whether the respondent smoked during most of last pregnancy, and whether the respondent was ever advised by a doctor to quit smoking. Other variables in the HPDP focus on health and fitness awareness, general health habits, injury control, child safety and health, high blood pressure, stress, exercise, smoking, alcohol use, dental care, and occupational safety and health. Variables from the core questionnaire include height, weight, age, race, sex, Hispanic origin, type of living quarters, region and metropolitan status of residence, marital status, veteran status, education, family income, health status, industry, occupation, activity limitation status, medical conditions, restricted activity days in the past two weeks, bed days in the past two weeks and past 12 months, time interval since the last doctor visit, and the number of doctor visits and short-stay hospital episodes in the past 12 months.

The purpose of the National Health Interview Survey (NHIS) is to obtain information about the amount and distribution of illness, its effects in terms of disability and chronic impairments, and the kinds of health services people receive. Implementation of a redesigned NHIS (ICPSR 2954), consisting of a basic module, a periodic module, and a topical module, began in 1997. The present collection consists of the basic module and topical modules on prevention, which contain pregnancy and smoking components along with information on prevention of illness and injury for adults and children. Each record in the Household-Level File (Part 1) of the basic module contains data on the type of living quarters, number of families in the household responding and not responding, and the month and year of the interview for each eligible sampling unit. The Family-Level File (Part 2) is made up of reconstructed variables from the person-level data of the basic module and includes information on sex, age, race, marital status, Hispanic origin, education, veteran status, family income, family size, major activities, health status, activity limits, and employment status, along with industry and occupation. As part of the basic module, the Person-Level File (Part 3) provides information on all family members with respect to health status, limitation of daily activities, cognitive impairment, and health conditions. Also included are data on years at current residence, region variables, height, weight, bed days, doctor visits, hospital stays, and health care access and utilization. A randomly-selected adult in each family was interviewed for the Sample Adult File (Part 4) regarding respiratory conditions, renal conditions, AIDS, joint symptoms, health status, limitation of daily activities, and behaviors such as smoking, alcohol consumption, and physical activity. The Sample Child File (Part 5) provides information from a knowledgeable adult in the household on medical conditions of one child in the household, such as respiratory problems, seizures, allergies, and use of special equipment such as hearing aids, braces, or wheelchairs. Also included are questions regarding child behavior and the use of mental health services. The Child Immunization File (Part 6) presents information from shot records and supplies vaccination status, along with the number and dates of shots, and information about the chicken pox vaccine. Episode-based information is found in the Injury Episode File (Part 7), while information in the Injury Verbatim File (Part 8) is comprised of narrative text describing injuries, including type of injury, how the injury occurred, and the body part injured. The Poison Episode File (Part 9) examines the cause and date of injury or poisoning, loss of time from work or school, and whether the poisoning resulted in hospitalization. The prevention modules are being examined to determine the "Healthy People Objectives for 2010," which have the aim of reducing or preventing illness and disease among Americans. The Pregnancy and Smoking Prevention Module (Part 10) contains a record for every woman 18-49 years of age and provides information on tobacco use and smoking during pregnancy. The Sample Adult Prevention Module (Part 11) examines injury prevention, environmental health issues, tobacco use, nutrition, workplace health promotion, heart disease, stroke, chronic diseases, clinical services used, preventive services used, cancer, oral health, physical activity, mental health, family discussions, and firearm safety. The Sample Child Prevention Module (Part 12) provides information on health conditions, dental care, and injury prevention, along with use of seat belts and safety equipment during participation in sports.

Geographic coverage: United States

Time period: 1994-01-01--2025-12-31

Downloads of Add Health require submission of the following information, which is shared with the original producer of Add Health: supervisor name, supervisor email, and reason for download. A Data Guide for this study is available as a web page and for download.

The National Longitudinal Study of Adolescent to Adult Health (Add Health), 1994-2018 [Public Use] is a longitudinal study of a nationally representative sample of U.S. adolescents in grades 7 through 12 during the 1994-1995 school year. The Add Health cohort was followed into young adulthood with four in-home interviews, the most recent conducted in 2008 when the sample was aged 24-32. Add Health combines longitudinal survey data on respondents' social, economic, psychological, and physical well-being with contextual data on the family, neighborhood, community, school, friendships, peer groups, and romantic relationships.

Add Health Wave I data collection took place between September 1994 and December 1995, and included both an in-school questionnaire and in-home interview. The in-school questionnaire was administered to more than 90,000 students in grades 7 through 12, and gathered information on social and demographic characteristics of adolescent respondents, education and occupation of parents, household structure, expectations for the future, self-esteem, health status, risk behaviors, friendships, and school-year extracurricular activities. All students listed on a sample school's roster were eligible for selection into the core in-home interview sample. In-home interviews included topics such as health status, health-facility utilization, nutrition, peer networks, decision-making processes, family composition and dynamics, educational aspirations and expectations, employment experience, romantic and sexual partnerships, substance use, and criminal activities. A parent, preferably the resident mother, of each adolescent respondent interviewed in Wave I was also asked to complete an interviewer-assisted questionnaire covering topics such as inheritable health conditions, marriages and marriage-like relationships, neighborhood characteristics, involvement in volunteer, civic, and school activities, health-affecting behaviors, education and employment, household income and economic assistance, parent-adolescent communication and interaction, parent's familiarity with the adolescent's friends and friends' parents.

Add Health data collection recommenced for Wave II from April to August 1996, and included almost 15,000 follow-up in-home interviews with adolescents from Wave I. Interview questions were generally similar to Wave I, but also included questions about sun exposure and more detailed nutrition questions. Respondents were asked to report their height and weight during the course of the interview, and were also weighed and measured by the interviewer.

From August 2001 to April 2002, Wave III data were collected through in-home interviews with 15,170 Wave I respondents (now 18 to 26 years old), as well as interviews with their partners. Respondents were administered survey questions designed to obtain information about family, relationships, sexual experiences, childbearing, and educational histories, labor force involvement, civic participation, religion and spirituality, mental health, health insurance, illness, delinquency and violence, gambling, substance abuse, and involvement with the criminal justice system. High School Transcript Release Forms were also collected at Wave III, and these data comprise the Education Data component of the Add Health study.

Wave IV in-home interviews were conducted in 2008 and 2009 when the original Wave I respondents were 24 to 32 years old. Longitudinal survey data were collected on the social, economic, psychological, and health circumstances of respondents, as well as longitudinal geographic data. Survey questions were expanded on educational transitions, economic status and financial resources and strains, sleep patterns and sleep quality, eating habits and nutrition, illnesses and medications, physical activities, emotional content and quality of current or most recent romantic/cohabiting/marriage relationships, and maltreatment during childhood by caregivers. Dates and circumstances of key life events occurring in young adulthood were also recorded, including a complete marriage and cohabitation history, full pregnancy and fertility histories from both men and women, an educational history of dates of degrees and school attendance, contact with the criminal justice system, military service, and various employment events, including the date of first and current jobs, with respective information on occupation, industry, wages, hours, and benefits. Finally, physical measurements and biospecimens were also collected at Wave IV, and included anthropometric measures of weight, height and waist circumference, cardiovascular measures such as systolic blood pressure, diastolic blood pressure, and pulse, metabolic measures from dried blood spots assayed for lipids, glucose, and glycosylated hemoglobin (HbA1c), measures of inflammation and immune function, including High sensitivity C-reactive protein (hsCRP) and Epstein-Barr virus (EBV).

Wave V data collection took place from 2016 to 2018, when the original Wave I respondents were 33 to 43 years old. For the first time, a mixed mode survey design was used. In addition, several experiments were embedded in early phases of the data collection to test response to various treatments. A similar range of data was collected on social, environmental, economic, behavioral, and health circumstances of respondents, with the addition of retrospective child health and socio-economic status questions. Physical measurements and biospecimens were again collected at Wave V, and included most of the same measures as at Wave IV.

The overall goal of Wave VI was to better understand life course trajectories, determinants, and consequences of critical dimensions of aging, health, and health disparities among U.S. early midlife adults. Data collection took place from 2022 to 2025, with participants between the ages of 39 and 51, with an average age of 44. Beyond longitudinal survey measures, newly added questions included those on cumulative stress, discrimination, despair, work-life balance, memory, physical limitations, and caregiving. Continuing from previous waves, home exams collected physical measurements and biospecimens with most of the same measures as Wave V.

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.

SATSA began in 1984, and six additional waves were conducted in 1987, 1990, 1993, 2004, 2007, and 2010. The questionnaire was initially sent to all twins from the Swedish Twin Registry who were separated at an early age and raised apart; the survey was also administered to a control sample of twins who were raised together. The respondents were surveyed on items that included health status, how they were raised, work environment, alcohol consumption, and dietary and smoking habits, as well as questions about personality and attitudes; this information comprised the first component. The second component was collected from a subsample composed of 150 pairs of twins raised apart and 150 pairs of twins raised together. This subsample participated in seven waves of in-person testing, which included a health examination, structured interviews, and tests on functional capacity, cognitive abilities, and memory. The data are represented according to questionnaire and time number, and correspond to each wave/year: Questionnaire 1 and In-Person Testing Time 1 were in 1984; Questionnaire 2 and In-Person Testing Time 2 were in 1987; Questionnaire 3 and In-Person Testing Time 3 were in 1990; Questionnaire 4 and In-Person Testing Time 4 were in 1993; Questionnaire 5 was in 2003; In-Person Testing Time 5 was in 2004; Questionnaire 6 and In-Person Testing Time 6 were in 2007; In-Person Testing Time 7 was in 2010. The Administrative and Cognitive datasets include data from all years/waves. The Smell Survey dataset only includes data from 1990. No years were specified for the Contact measures and Separation measures datasets. Demographic and background information includes age, sex, education, family history, household composition and employment.

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

Geographic coverage: United States

Time period: 1980-01-01--1980-12-31, 1983-01-01--1983-12-31, 1988-01-01--1988-12-31, 1992-01-01--1994-12-31, 1997-01-01--1997-12-31, 2000-01-01--2000-12-31

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.
