Best Practices to Reduce COVID-19 in Group Homes for Individuals with Serious Mental Illness and Intellectual and Developmental Disabilities, Massachusetts, 2021-2022 (ICPSR 39404)

Released/updated on: 2025-09-18

Geographic coverage: United States, Massachusetts

Time period: 2021-01-01--2022-01-01

The overall goal for this project was to reduce the incidence of COVID-19, hospitalization, and mortality among adults with serious mental illness (SMI) and intellectual disabilities/developmental disabilities (IDD) in congregate living settings (i.e., group homes) in Massachusetts, as well as to reduce COVID-19 incidence among staff who work in these settings. The research team was guided by two comparative effectiveness questions:

With the goal of prioritizing and making actionable best practices available as resources, what is the comparative effectiveness of various types and intensities of preventative interventions (e.g., screening, isolation, contact tracing, hand hygiene, physical distancing, use of face masks) in reducing rates of COVID-19, related hospitalizations, and related mortality in this population?
With the goal of effectively implementing best practices, what is the most effective implementation strategy to reduce rates of COVID-19 in this population: using tailored best practices (TBP) with SMI/IDD residents and staff of group homes in mind, or general best practices (GBP) from state and federal standard guidelines for all congregate care settings?

The specific aims of this study were as follows:

Aim 1a. Synthesize existing baseline data collected by 6 state behavioral health agencies on COVID-19 rates, hospitalization, mortality, and use of infection prevention practices.

Aim 1b. Collect stakeholder input via surveys and virtual focus groups on staff and resident experiences and on barriers/facilitators to implementing recommended preventative practices.

Aims 2a and 2b. Determine the comparative effectiveness of various COVID-19 preventative practices by (Aim 2a) using a validated simulation model to estimate COVID-19 spread in group homes and (Aim 2b) obtaining stakeholder input on prioritizing and defining tailored best practices for implementation.

Aim 3. Compare the effectiveness of TBPs with GBPs by using a hybrid effectiveness-implementation cluster randomized controlled trial.

Data collected to answer Aims 1 and 2 served as the foundation for designing the Aim 3 trial. Data for the trial were collected in 3-month intervals beginning January 2021 (baseline) until October 2022 (15-month follow-up). Residents and staff were sampled from approximately 400 group homes. Primary implementation outcome measures were COVID-19 vaccination rates and fidelity scores. The primary effectiveness outcome measure was COVID-19 infection.

Notes: This collection contains only data from Aim 1a and Aim 3. Throughout the data and documentation, "intellectual and/or developmental disabilities" is abbreviated as both IDD and ID/DD.

CBS News/60 Minutes/Vanity Fair National Poll, November #2, 2011 (ICPSR 34475)

Released/updated on: 2013-01-10

Geographic coverage: United States

This poll, fielded November, 2011, and the second of three, is part of a continuing series of monthly surveys that solicits public opinion on a range of political and social issues. Respondents were asked about whether the country was moving in the right direction, the importance of buying products made in the United States, and United States business practices. A variety of social questions sought opinions about what chore respondents' most disliked, Apple Inc., the danger of vaccinations, email etiquette, whether they would go back to school if it was free, and the most important phrase to learn before traveling. Supplementary questions asked respondents to guess Mitt Romney's first name and how many people they thought lived in the United States, whether there should be a global religion, whether they supported the Tea Party movement and/or the Occupy Wall Street movement, and whether they opposed the reinstatement of the military draft. Finally, respondents were asked about their personal finances and holiday shopping, as well as other holiday related questions. Demographic information includes sex, age, race, marital status, education level, household income, employment status, religious preference and participation, whether respondents thought of themselves as born-again Christians, type of residential area (e.g., urban or rural), political party affiliation, political philosophy, voter registration status, voting behavior, whether they served in the armed forces, household composition, and the number of phones in their household.

Census of Juveniles in Residential Placement and Juvenile Residential Facility Census, 1997-2010 -- Concatenated Matched Data [United States] (ICPSR 27543)

Released/updated on: 2013-03-08

Geographic coverage: North Carolina, Indiana, Wyoming, Utah, Arizona, Montana, Kentucky, California, Kansas, Florida, Delaware, Pennsylvania, Mississippi, Iowa, Illinois, Texas, Connecticut, Georgia, Virginia, Maryland, Idaho, Oregon, Vermont, United States, Oklahoma, Tennessee, Maine, Alabama, Arkansas, Washington, South Carolina, Nebraska, West Virginia, Massachusetts, Colorado, Missouri, Alaska, North Dakota, Wisconsin, Nevada, District of Columbia, Rhode Island, South Dakota, Hawaii, Minnesota, New York (state), New Jersey, Michigan, New Mexico, New Hampshire, Louisiana, Ohio

This collection includes data from the CENSUS OF JUVENILES IN RESIDENTIAL PLACEMENT (CJRP), 1997-2010 -- CONCATENATED DATA [UNITED STATES] (ICPSR 27541) and the JUVENILE RESIDENTIAL FACILITY CENSUS (JRFC), 2000-2010 -- CONCATENATED DATA [UNITED STATES] (ICPSR 27542) that were matched on the facility identifier to create one data file. The CJRP asked juvenile residential custody facilities in the United States to describe each youth assigned a bed in the facility on a specified reference date. For 1997, the reference date was the fifth Wednesday in October. For 1999-2003 and 2007, the reference date was the fourth Wednesday in October. For 2006 and 2010, the reference date was the fourth Wednesday in February. Characteristics of the facility, treatment services, and facility population were also collected in the CJRP. The JRFC collected information on facility characteristics, including size, structure, security arrangements, ownership, and use of bed space in the facility. The JRFC used four modules to collect information on the physical health services, educational services, substance abuse treatment, and mental health treatment provided to youth in these facilities. These four modules were not always collected each year. The JRFC also identified the type of facility, which was complemented with a series of questions about other residential services provided by the facility, such as independent living, foster care, or other arrangements. The JRFC has been administered biennially since 2000, in even-numbered years. The JRFC census reference date is the fourth Wednesday in October. Each record in the concatenated matched data file provides information about the juvenile and also includes the characteristics of the facility in which the juvenile was held from both the CJRP and JRFC collections. Therefore, these data can be analyzed at the juvenile or facility level. Only facilities that held at least one juvenile for an offense on the CJRP census reference date are included in this file, i.e., all facilities in the biennial JRFC data may not be included in this concatenated matched file. Data were harmonized so that variables present across years are identically named to facilitate analysis.

COEP Replication package for "Indoor Vaccine Mandates in U.S. Cities, Vaccination Behavior, and COVID-19 Outcomes" (ICPSR 238877)

Released/updated on: 2025-10-15

Geographic coverage: United States

Time period: 2020-12-21--2022-04-18

Many U.S. cities introduced indoor vaccine mandates in 2021–2022 to increase COVID-19 vaccination and curb transmission. While national mandates abroad boosted uptake, the effects of city-level mandates in the U.S. remain unclear. Using the synthetic difference-in-differences methodology, we estimate the impact of mandates in nine major cities on first-dose uptake, cases, and deaths. We find no consistent pattern of significant effects, and results are robust across estimators, outcome definitions, lag structures, and donor pool choice. The contrast with international findings suggests localized mandates may be less effective in settings with high baseline coverage, mobility across jurisdictions, and vaccine hesitancy.

Comparing Patient-reported Impact of COVID-19 Shelter-in-place Policies and Access to Containment and Mitigation Strategies Overall and in Vulnerable Populations, United States, 2020-2022 (ICPSR 39218)

Released/updated on: 2025-08-05

Geographic coverage: United States

Time period: 2020-04-22--2021-12-31, 2020-03-26--2023-10-26

The COVID-19 Citizen Science (CCS) Study was launched early in the pandemic to collect patient-reported information about exposures, risk behaviors and outcomes relevant to the pandemic. The Patient-Centered Outcomes Research Institute (PCORI) funded the research team to expand recruitment into CCS using PCORnet, the National Patient-Centered Clinical Research Network, and to use the resulting data to compare the patient-reported impact of pandemic associated policies. The research team systematically collected pandemic-associated policies enacted by counties across the United States (focusing in areas where there were many CCS participants), and to do so on a weekly basis from the beginning of the pandemic using publicly available sources.

Researchers combined data from various sources to answer two primary research questions (RQ):

What is the comparative impact of different shelter-in-place/reopening policies, overall and in vulnerable populations, on patient-reported financial insecurity, mental health, and other subjective outcomes important to patients?
What is the comparative effectiveness of county-level containment and mitigation strategies at achieving timely access to COVID-19 vaccination, testing, healthcare, information and contact tracing?

The research team collected patient-reported data from the CCS study and policy data from the U.S COVID-19 County Policy (UCCP) database. Electronic health record (EHR) data were also available from some participants recruited from health systems located across 7 U.S. states who consented and authorized use of these data for the study. Data for these participants were extracted from the PCORnet Common Data Model (CDM). Additional county-level contextual variables were included in analysis.

This collection contains CCS survey data on patient-reported anxiety with county-level policies data (DS1), respondent demographics (DS2), baseline survey results (DS3), daily (DS4) and weekly (DS5) COVID-19 symptoms reports, COVID-19 vaccination surveys repeated monthly (DS6) as well as a one-time vaccination survey (DS7), and pandemic impacts check-in surveys (DS8). CDM datasets include logistic regression model outcomes to predict study enrollment among all invited participants (DS9), codes for immunizations (DS10), laboratory tests (DS11), and procedures (DS12). County-level variables are also available for years 2021 (DS13) and 2023 (DS14).

COVID-19 Trends and Impact Survey (CTIS), Global, 2020-2022 (ICPSR 39206)

Released/updated on: 2025-06-03

Geographic coverage: Global

Time period: 2020-01-01--2022-01-01

The COVID-19 Trends and Impact Survey (CTIS) was conducted by the Delphi Group at Carnegie Mellon University (CMU) in the United States (US) and by the University of Maryland (UMD) Social Data Science Center (SoDa) globally, in partnership with Meta. CTIS was a daily repeated cross-sectional survey that ran continuously starting April 6, 2020 in the US and starting April 23, 2020 globally. Both surveys concluded data collection on June 25, 2022. CTIS collected data in 200+ countries and territories, including 114 where Meta provided survey weights. The sampling frame was Facebook users aged 18 years or older who have been active on the platform in the last month. Sampled Facebook users saw the invitation at the top of their Feed, but the surveys were collected by the universities using Qualtrics. Meta neither collected nor received survey responses. The sample was stratified by subnational regions. Respondents were sampled as frequently as every month and as infrequently as every six months, depending on the population density of the subnational region in which they lived. Due to the minimum sampling frequency, pooled analyses should not combine more than a month of data. There were 12 versions of the survey questionnaires. The Delphi US CTIS was translated into 8 languages. The UMD Global CTIS was translated into 66 languages.

This collection is comprised of three categories of data:

a. Individual-level microdata files, which will be available to eligible academic and nonprofit researchers with fully executed Data Use Agreements (DUAs).

b. Daily aggregate estimates at the country and subnational region levels disseminated via public APIs at CMU and UMD.

c. Weekly and monthly aggregate estimates broken out by respondent characteristics (e.g., age, gender, vaccination status) at the country and subnational administrative level-1 region-level disseminated via publicly available CSV-formatted contingency tables.

This collection currently only contains the aggregate data, contingency tables and associated documentation. The microdata are forthcoming.

Time period: 2020-04-01--2022-06-01

The United States COVID-19 Trends and Impact Survey (CTIS) was a voluntary survey of Facebook users in the United States conducted from April 2020 to June 2022. CTIS was intended to aid in pandemic forecasting and response at fine spatiotemporal detail. Through collaboration with Meta, it randomly sampled Facebook active users at a rate sufficient to provide roughly 35,000 responses per day, on average. Survey questions covered topics including COVID-like symptoms, behavior (such as social distancing), COVID testing, mental health, health-related beliefs, trust in officials and information sources, schooling, vaccination acceptance and hesitancy, and related subjects. Respondents provided their ZIP code. Demographic variables include age, gender, education, race/ethnicity, and occupation. Meta generated survey weights to correct for non-response and to match the US adult population age and gender distribution.

The 27 datasets make up the microdata. Users should see the Microdata User Guide for documentation on the use and interpretation of the microdata files.

Two zip files are available for public download: a monthly data zip file and a weekly data zip file. These include the aggregate data. To access these files, go to the "Download" tab and select "Other." Ensure you have enough storage space before proceeding, as the files are large.

Geographic coverage: Detroit, United States, Michigan

Time period: 2021-01-06--2021-03-05

The Detroit Metro Area Communities Study (DMACS) is a panel survey of Detroit residents launched in 2016. The original panel of respondents was drawn from an address-based probability sample of all occupied Detroit households. In subsequent years, the panel has been refreshed through additional address-based sampling. The 12th survey wave, collected between January 6, 2021 and March 5, 2021 included a sample refresh using multiple recruitment modes (mail, email, text, and phone). The researchers sent a total of 11,655 invitations to the survey: 1,766 to existing DMACS panelists who had already responded to at least one prior survey and 9,889 to residents of a randomly-selected address-based refreshment sample of Detroit households. This refreshment included an oversample of households in Census block groups that were at least 70% Hispanic and households in Strategic Neighborhood Fund (SNF) neighborhoods. Surveys were self-administered online or interviewer-administered via telephone. Adaptive design was used to increase response rates amongst hard-to-reach subgroups. The researchers report results for the 2,238 Detroit residents who completed the survey. The researchers obtained an overall response rate of 20.22% (using American Association for Public Opinion Research (AAPOR) Response Rate 1); 72.6% for existing panelists and 10.4% for new panelists.

Time period: 1989-10-12--1989-11-22

This round of Euro-Barometer surveys had for its major focus issues involving drugs, alcohol, cancer, and the single European market. Respondents were asked to consider the influence of the environment, the anticipated effects of the Single Market of 1992, and the repercussions of an aging population on public health. Moreover, respondents were asked to identify and prioritize the most serious health problems facing the European Community, and also to evaluate the various efforts being made to combat these problems. Health topics addressed included drugs and drug addiction, cancer, smoking, alcoholism, AIDS, cardiovascular disease, education, diet, and vaccinations. Other major questions involved additional effects of the Single European Market of 1992, and whether certain issues of public policy should be decided by national governments or jointly within the European Community. Also, the survey gauged respondents' perceptions of the European Parliament and the Commission of the European Communities, along with categorizing opinions on the Soviet Union and President Gorbachev, the United States and President Bush, the role and relevance of NATO, U.S. military presence in Western Europe, and the possibility of economic cooperation with Poland and Hungary. Respondents were also asked to give examples of why they felt the United Nations was doing either a good or a poor job in solving the problems it had to face, to name various agencies and institutions that were part of the United Nations, and to identify the Secretary General of the United Nations. Respondents were queried regarding their source of information and education on the United Nations, and were asked to indicate their level of interest in receiving more information on pertinent United Nations issues. As in previous Euro-Barometers, questions on political party preference asked respondents which party they felt the closest to, how they voted in their country's last general election, how they would vote if a general election were held tomorrow, and, if not sure, which party they would be most inclined to vote for. Respondents were also asked to comment on the ideal number of children a family should have, factors influencing the number of children parents decide to have, the role of the family in society, and what government can do to improve life for families. Other items included life satisfaction, use of and attitudes toward dairy products, interest in politics, priority of national goals, political party membership, and union membership. Additional information was gathered on family income, number of people residing in the home, size of locality, region of residence, occupation of the head of household, and the respondent's age, sex, occupation, education, religion, religiosity, subjective social class standing, socio-professional status, and left-right political self-placement.

To study the impact of COVID-19 pandemic on frontline healthcare workers in the United States over time, the Healthcare Worker Exposure Response and Outcomes (HERO) Registry was created in 2020 to form a virtual research community of healthcare workers (and later, their family members and community members). The registry was intended for healthcare workers interested in completing research studies related to the COVID-19 pandemic and its impacts on their lives. Observational data were collected at various timepoints between April 2020 and September 2022 via web-based questionnaires available on the HERO Registry online portal.

This collection contains 39 sets of data from over 50,000 HERO Registry members. Datasets represent separate surveys with distinct survey designs and sampling criteria. Surveys focused on health history, workplace experiences, COVID-19 exposure, social support, mental health, and the respondents' willingness to remain in or leave the healthcare field. Datasets 24 through 39 represent "hot topics" such as vaccines, vaccine willingness and uptake, childcare and school arrangements, and staffing shortages. Datasets for registry administration, respondent demographics, and survey eligibility criteria are also included.

Influence of the COVID-19 Pandemic on New York City Public School Children's Longitudinal Health and Education Outcomes, 2020-2022 (ICPSR 38856)

Released/updated on: 2025-02-25

Geographic coverage: New York City, United States, New York (state)

Time period: 2020-01-01--2022-01-01

This study examines how significant disruptions to children's health, education, and overall well-being during the COVID-19 pandemic created lasting influence on health, development, and social trajectories through the lifecourse, and the risk for long-term health outcomes. The research leverages the New York City (NYC) Student Population Health Registry (SPHR), a uniquely inclusive, longitudinal database of all NYC public school students created jointly by the NYC Department of Health and Mental Hygiene and NYC Department of Education, along with other publicly available data sources.

Research to date has focused on racial and geographic disparities in school-level vaccination rates, and on racial and ethnic group differences in New York City schoolchildren becoming fully vaccinated (two doses) within 6 months of vaccine eligibility. Future research is expected to focus on outcomes such as increased incidence and exacerbation of chronic diseases like obesity, asthma, and diabetes; stress and anxiety; and educational consequences such as declines in academic achievement (test scores), increases in chronic absenteeism, repeating grades, or high school dropout. Also of interest are the mitigating effects of child-, classroom-, and school-level vaccination rates, and neighborhood and school characteristics such as income, vaccination sites, emergency food resources, and open space.

The ICPSR provides variable-level metadata for the data associated with this study. The actual data may only be available from the Principal Investigator directly. The variable descriptions available through ICPSR also include information regarding the source of each variable listed, as does the Data Source field of these metadata.

Juvenile Residential Facility Census, 2000-2010 -- Concatenated Data [United States] (ICPSR 27542)

Released/updated on: 2013-03-08

The Juvenile Residential Facility Census (JRFC) collected basic information on facility characteristics, including size, structure, security arrangements, and ownership. It also collected information on the use of bedspace in the facility to indicate whether the facility was experiencing crowding. The JRFC included questions about the type of facility, such as detention center, training school, ranch, or group home. This information was complemented by a series of questions about other residential services provided by the facility, such as independent living, foster care, or other arrangements. JRFC used four modules to collect information on the physical health services, educational services, substance abuse treatment, and mental health treatment provided to youth in these facilities. These four modules were not always collected each year. While not evaluating the effectiveness or quality of these services, the JRFC gathered important information about the youth the services were directed toward and how the services were provided. The census indicated the use of screenings or tests conducted to determine counseling, education, health, or substance abuse needs, and also examined prominent issues about conditions of confinement, including the restraint of youth and improper absences from the facility. The JRFC has been administered biennially since 2000, in even-numbered years. The census reference date is the fourth Wednesday in October.

Time period: 2001-01-01--2002-01-01

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 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.

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.

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.

This supplement includes variables from the NHIS core Person File (see NATIONAL HEALTH INTERVIEW SURVEY, 1993 [ICPSR 6534]), including sex, age, race, education, family income, limitation of school activities, family relationship, and relationship to reference person. For this supplement, information was collected on vaccines received by children under 6 years old for diphtheria/tetanus/pertussis (DPT), polio, measles or MMR, hemophilus type B or HIB, and hepatitis B, the number of shots the child received for each type of vaccine, and other types of shots received. Interviews were conducted with adult respondents, and vaccine information was gathered, when possible, from records maintained by the family.

National Immunization Survey (NIS), 1995 (ICPSR 3875)

Released/updated on: 2004-04-07

Geographic coverage: United States

This survey is the first in a series that was designed to track the rates of proper vaccination of children in the United States. The target age range for the children was 19 to 35 months. Respondents were queried on the number of children present in the household between the ages of 12 months and 3 years, those children's dates of birth, their sex, whether there were vaccination records for the children, whether those records were accessible, whether the respondent was the adult in the household most knowledgeable about the vaccinations, and whether the respondent accompanied the children to more than 50 percent of their vaccinations. For each child in the household, information was gathered on whether each child had received all of the recommended vaccinations, and the number of the diphtheria-tetanus-pertussis shots (DTP or DT), polio vaccinations, measles vaccinations, meningitis or Haemophilus Influenzae type B (HIB) shots, and hepatitis B (Hep B) shots each child had received. Further information was obtained about additional vaccinations the child may have received to combat diseases such as tuberculosis, typhoid, yellow fever, and malaria, the child's health care providers, the number of doctors that had performed vaccinations, and whether the measles vaccination was strictly for measles or for the measles-mumps-rubella (MMR) combination. Once parental consent was obtained, health care providers were queried on the vaccination records for each child whose vaccination information was gathered from parents. Health care providers were queried on the type and the level of detail of the vaccination records for each child, the dates and types of vaccinations administered, the date of each child's first visit to that provider regardless of reason, the date of the child's most recent visit to that provider regardless of reason, and the type of care the provider gave to the child. Health care provider respondents were asked to describe their facility, to give their position within the facility, the child's date of birth according to their records and whether the child was known by another last name, and to provide a list of any additional health care providers for that child. Demographic information provided by the parents or guardians includes the number of people living in the household, the number of people over and under 18 in the household, ethnicity of the child and respondent, marital status of the respondent, respondent's relationship to the child, respondent's education level or that of the child's mother, household income, and whether the child was living at the same address as when he or she was born.

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.

These data were collected as part of an assessment of in-person and webinar AFIX consultations on best practices for adolescent HPV immunization. AFIX (which stands for Assessment, Feedback, Incentives, and eXchange) is a program of the Center for Disease Control and Prevention aimed at increasing vaccination of children and adolescents by reducing missed opportunities to vaccinate and improving immunization delivery practices at the provider level.

High-volume primary care clinics serving over 370,000 patients ages 11-17 in three states were randomly assigned to receive no consultation or an in-person or webinar AFIX consultation focused on improving adolescent HPV immunization. Immunization specialists from participating state health departments delivered the consultations. Physicians, nurses and other clinic staff in the in-person and webinar arms who participated in the consultation sessions completed web-based surveys pre-consultation (pre-visit survey), post-consultation (post-visit survey) and at six-month follow up (follow-up survey). Topics covered by the surveys include participation in and satisfaction with the assigned consultation delivery mode; strategies for improving HPV vaccination coverage used by the respondents' clinics; opinions about the level of HPV vaccination coverage in the respondents' clinics; and the respondents' self-efficacy for improving HPV vaccination coverage.

Project Migrante: Health Status and Access to Health Care Among Migrants on Mexico's Northern Border, 2020-2021 (ICPSR 38601)

Released/updated on: 2023-06-07

Geographic coverage: Tijuana, Matamoros, Mexico, Ciudad Juárez

Time period: 2020-01-01--2021-01-01

The Migrante Project is a binational study that examines health status and access to health care among Mexican migrants. Since 2007, Migrante investigators have implemented a series of cross-sectional probability-based surveys on Mexico's northern border. The current phase of Migrante includes three survey waves (N=1,200 each), each focused on a specific topic area. Data for the Wave I survey focused on HIV and sexual/reproductive health. Wave II is focused on non-communicable disease. Data collection for this wave is ongoing. Wave III (data to be collected in 2023) will focus on mental health and substance use. All surveys contain additional questions on socio-demographics, health status, health care access, migration history, and contextual factors related to migration stage. All waves also include biometric testing (for example, rapid HIV testing). Participants are sampled from four different migrant flows:

Northbound flow: Migrants traveling north and arriving at the border from other regions in Mexico
Southbound flow - Border: Migrants traveling from the Mexico side of the Mexico-US border to points farther south
Southbound flow - U.S.: Migrants returning to Mexico from the U.S. voluntarily
Deported flow: Migrants returning to Mexico from the U.S via deportation

The data herein come from the Wave I survey and were collected in Tijuana, Matamoros, and Ciudad Juárez, Mexico between August 2020 and September 2021. The study employed a multistage sampling design, with a combination of geographic and temporal sampling units, modeled after the Encuesta sobre Migración en la Frontera Norte de México (EMIF Norte). Migrante sampling sites for Wave I included bus stations, airports, and deportation stations in each of the three cities.

Eligible individuals were at least 18 years old, born in Mexico or other Latin American countries, fluent in Spanish, not residents of the city where the survey is being conducted (except for deported migrants), and traveling for labor reasons or change of residence. In total, there were 1,398 observations (northbound flow N=347, southbound flow N=703, and deported flow N=348) in Wave I, with 1,257 individuals completing the Wave I survey. Three hundred and six of these individuals belonged to the deported flow, 306 to the northbound flow, 336 to the southbound border flow, and 309 to the southbound U.S. flow. Consent rates ranged from 13% to 98% depending on the flow and survey city. Migrante surveys can be used to produce population-level estimates of health outcomes and health care access, investigate variations across migration phases, and explore the impact of health care and immigration policies on migrants' health outcomes, healthcare access, and individual and environmental health determinants.
