This data collection, Aging of Veterans of the Union Army: Surgeons' Certificates, United States, 1862-1940, constitutes a portion of the historical data collected by the project "Early Indicators of Later Work Levels, Disease, and Death." With the goal of constructing datasets suitable for longitudinal analyses of factors affecting the aging process, the project collects military, medical, and socioeconomic data on a sample of white males mustered into the Union Army during the Civil War. The surgeons' certificates contain information from examining physicians to determine eligibility for pension benefits. Also included are questions regarding the age, occupation, residence, and military experience of the veterans. These data can be linked to "Aging of Veterans of the Union Army: Military, Pension, and Medical Records, 1820-1940" (ICPSR 6837) and "Aging of Veterans of the Union Army: United States Federal Census Records, 1850, 1860, 1900, 1910" (ICPSR 6836) using the variable "recidnum."

The Analysis of Longitudinal Claims Databases (R1 Part A): Aging Trajectories of Chronic Disease, Psychological Morbidity, and Mortality, United States is the first of a three-part project that examined claims data from Medicare, Medicaid, and/or Optum databases to explore aging trajectories, use of preventative services, and healthcare outcomes for individuals with several types of physical disabilities.

There is a well-established interrelationship between access to healthcare and the age-related co-occurrence of two or more chronic conditions, adverse health events, and cost of care among people with a physical disability (PWPD). However, the extent to which health outcomes and healthcare costs interact with a wide range of social factors, including type and depth of insurance coverage, has received little attention. There is also scarce evidence regarding the aging trajectories of chronic diseases and psychological conditions among PWPD, as well as how these factors contribute to healthcare costs and adverse health events, including early mortality. Three specific aims guide this research investigation:

1. Determine the longitudinal trends of cardiometabolic diseases, the age-related co-occurrence of two or more chronic conditions (or multimorbidity), diagnosed physiological conditions, and musculoskeletal diseases common among individuals diagnosed with a physical disability ordered by type of insurance (public vs. private).
2. Identify the independent and joint contributions of medical factors (e.g., age, multimorbidity, disease severity, etc.) and social and environmental factors (e.g., income, education, and insurance) on adverse health events (including mortality), healthcare use, and costs.
3. Quantify how changes in medical and social factors predict or facilitate adverse health events and healthcare costs among individuals with specific diagnoses of physical disabilities.

This is a collection of 2,888 clinical MRIs of patients admitted at a National Stroke Center, over ten years, with clinical diagnosis of acute or early subacute stroke. The collection includes diverse MRI modalities and protocols. The infarct core was manually defined in the diffusion weighted images; the images are provided in native subject space and in standard space (MNI), in Neuroimaging Informatics Technology Initiative (NIfTI) format. The data format and organization follows Brain Imaging Data Structure (BIDS) guidelines. The collection includes diverse metadata, comprised of demographic information, basic clinical profile (NIH Stroke Scale/Score (NIHSS), hospitalization duration, blood pressure at admission, BMI, and associated health conditions), and expert description of the acute lesion. This resource provides high quality, large scale, human-supervised knowledge to feed artificial intelligence models and enable further development of tools to automate several tasks that currently rely on human labor, such as lesion segmentation, labeling, calculation of disease-relevant scores, and lesion-based studies relating function to frequency lesion maps.

The dataset is divided in folders with 60-70 subjects. Each folder contains the "raw data" (multimodal MRIs, in native space), "DWI-mask" (manually-defined lesion masks, brain masks, and 3D DWI, b0, and recalculated ADC), "DWI-MNI-IntensityNormalized" (DWI and lesion masks in MNI coordinates), and "phenotype" (individual ".tsv" files with metadata of each subject). The "templates" folder contains images averages and lesion frequency maps. The "documentation" contains comprehensive data documentation, the phenotypes of the whole dataset, and the data dictionary.

The Annual Health Survey (AHS), conducted by the Government of India between July 2010 and May 2013, investigates maternal and child health in nine states: Assam, Bihar, Chhattisgarh, Jharkhand, Madhya Pradesh, Orissa, Rajasthan, Uttarakhand, and Uttar Pradesh. These states constitute about 70 percent of neonatal deaths in India and about one-in-five neonatal deaths globally. The AHS consists of a three-round panel that interviewed over 4 million households in each round, as well as a one-time Clinical, Anthropometric, and Bio-Chemical Survey (CAB). The data were originally released to the public in 2015 as a set of 45 .csv files. The .csv files are included in a restricted-use zipped package as part of the ICPSR release (see dataset 21).

The survey focused on topics such as household composition, caste, fertility, family planning, pre- and post-natal care, breastfeeding, infant mortality, illness, disease, disability, and health care practices. Demographic information includes sex, age, education, occupation, marital status, household size, and religion. The CAB files contain biometric data including but not limited to height, weight, blood pressure, hemoglobin, pulse, and blood glucose.

Potential data users should note that the public-use and restricted-use versions of the datasets are the same except for the masking of day component variables for certain dates in the public-use versions of the files (please see the Description of Variables section for full details). Therefore, only researchers with a limited set of research questions that require full birth, marriage, and death dates will need to apply for the restricted-use versions of the data files.

Additionally, because the final data files are very large and potentially very time consuming to analyze on personal computers, researchers have the option to download ten-percent samples of each file (see datasets 3, 4, 7, 8, 11, 12, 15, 16, 19, and 20). These samples contain the same variables as the original files but only ten percent of the records. The samples were determined by taking a randomly selected ten percent of households in each district. P.I. codebooks were not produced for these samples. Please note that the ten-percent samples for each dataset were selected independently, so it is not advised to merge across datasets within the AHS using these samples, as the match rates will be very low.

This study evaluated the impact of atypical work hours on physiological indicators of health and chronic disease among law enforcement officers enrolled in the Buffalo Cardio-Metabolic Occupational Police Stress (BCOPS) study. Atypical work hours were defined as: work outside of a standard daytime work shift, the number of shift changes that occur over an extended period, the effect of cumulative overtime hours, and/or secondary employment. The data in this release include measures of global DNA methylation, which is an indicator of genomic instability and risk factor for several types of cancer; food logs documenting wake, sleep, and meal times during workdays and off-duty days; and survey data about psychosocial adaptive and maladaptive behaviors associated with atypical work hours.

Asthma is one of the nation's most common and costly chronic conditions, affecting over 38 million Americans at some time in their lives. Managing asthma requires a long term, multifaceted approach, including patient education, behavior changes, asthma trigger avoidance, pharmacological therapy, and frequent medical follow-up. This study provides asthma data available at the state and local level to direct and evaluate interventions undertaken by asthma control programs located in the state health departments. Improved tracking for asthma is critical for planning and evaluating efforts to reduce the health burden from the disease.

The Behavioral Risk Factor Surveillance System (BRFSS) is a state-based system of health surveys that collects information on health risk behaviors, preventive health practices, and health care access primarily related to chronic disease and injury. For many states, the BRFSS is the only available source of timely, accurate data on health-related behaviors. BRFSS was established in 1984 by the Centers for Disease Control and Prevention (CDC); currently data are collected monthly in all 50 states, the District of Columbia, Puerto Rico, the United States Virgin Islands, and Guam. More than 350,000 adults are interviewed each year, making the BRFSS the largest telephone health survey in the world. States use BRFSS data to identify emerging health problems, establish and track health objectives, and develop and evaluate public health policies and programs. The BRFSS is a cross-sectional telephone survey conducted by state health departments with technical and methodological assistance provided by CDC. States conduct monthly telephone surveillance using a standardized questionnaire to determine the distribution of risk behaviors and health practices among adults. Responses are forwarded to CDC, where the monthly data are aggregated for each state, returned with standard tabulations, and published at the year's end by each state. The BRFSS questionnaire was developed jointly by CDC's Behavioral Surveillance Branch (BSB) and the states. Data derived from the questionnaire provide health departments, public health officials, and policymakers with necessary behavioral information. When combined with mortality and morbidity statistics, these data enable public health officials to establish policies and priorities and to initiate and assess health promotion strategies. Demographic variables include race, age, sex, education level, marital status, employment status, and income level.

Overview: The goal of the project was to develop a unique database linking chronic disease clinical data from an electronic medical record (EMR) of a large academic healthcare system to multi-payer claims data. The longitudinal relational database can be used to study clinical effectiveness of many diagnostic and treatment interventions. The population of patients used consisted of those patients who were attributed to the University of Michigan Health System (UMHS) as continuing care patients, who are also in adjudicated and validated chronic disease registries.

Data Access: These data are not available from ICPSR. The data are restricted to use by the principal investigator and cannot be shared.

The COMBINE study was a longitudinal examination of pediatric Crohn's Disease (CD) patients in the United States with data collected from 2015-2022. This study was a randomized, double blind, placebo controlled pragmatic trial to compare low dose oral methotrexate versus a placebo in children with Crohn's disease initiating anti-TNF (tumor necrosis factor) therapy with Infliximab or Adalimumab. Eligible participants were randomized with a 1:1 allocation and followed for a minimum of 12 months and maximum of 36 months in the context of routine clinical care. The primary outcome was a composite of indicators of treatment failure and/or toxicity. Secondary outcomes included patient reported outcomes of pain interference and fatigue.

Crohn's disease (CD) is a chronic inflammatory bowel disease (IBD) that affects approximately 600,000 Americans with estimated direct costs of $3.6 billion annually. Typical symptoms (e.g., abdominal pain, bloody diarrhea) result in substantial morbidity, including hospitalization and surgery, missed work and school, and diminished quality of life. The primary treatment goals for all CD patients are to induce remission by eradicating intestinal inflammation and related symptoms and maintain remission by preventing disease flares and progression. Additional treatment goals for pediatric CD include restoring physical and emotional development.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the August 2006 basic CPS questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in May 2006 (ICPSR 24781) and January 2007 (ICPSR 24783). These three supplements comprise the 2006-2007 waves of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

The TUS, like most CPS supplements, was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the August 2006 supplement items. Beginning in August 2006, 15-17 year old respondents were phased out of the TUS and they were entirely omitted from the January 2007 sample due to Census Bureau budget constraints.

The TUS consisted of items PEA1 through SINTTP. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEAJ1A1-PEAJ1A4 and PEJ2A1-PEJSA4).

In addition to these smoking and other tobacco use status questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state of purchase

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Awareness of 1-800-QUIT-NOW

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2006-2007 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, use of quitlines, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

Demographic information collected include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

Additionally, self-respondents were asked various questions depending on their smoking status -- former, everyday, or occasional (items PES36-PES46 and PES55-PES61). Current everyday and occasional smokers were then asked whether the medical community had advised them to quit smoking or if they were planning to quit in the near future (items PES47-PES54). Self-respondents were further queried on smoking policies in their work place (items PES67-PES71), smoking rules in the home (item PES73) and questions on opinions about smoking (items PES72, PES75-PES77).

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected includes age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

This data collection is comprised of responses from two sets of survey questionnaires, the basic Current Population Survey (CPS) and a survey administered as a supplement to the November 2003 questionnaire on the topic of tobacco use in the United States. The Tobacco Use Supplement (TUS), sponsored by the National Cancer Institute and the Centers for Disease Control and Prevention, was also administered in February 2003 (ICPSR 4526) and June 2003 (ICPSR 4527). These three supplements comprise the 2003 wave of TUS data.

The basic CPS, administered monthly, collects labor force data about the civilian noninstitutional population living in the United States. Moreover, the CPS provides current estimates of the economic status and activities of this population which includes estimates of total employment (both farm and nonfarm), nonfarm self-employed persons, domestics, and unpaid helpers in nonfarm family enterprises, wage and salaried employees, and estimates of total unemployment. Data from the CPS are provided for the week prior to the administration of the survey.

The TUS, like most CPS supplements, was designed to be a proxy response supplement, meaning a single respondent could provide answers for all eligible household members, provided the respondent was a household member 15 years of age or older. Unique to the TUS design were also a set of self-respondent supplement questions. All household members age 15 years and older who had completed the basic CPS core items were eligible for the November 2003 supplement items.

The TUS consisted of items PEA1 through PEK5. Self-respondents were eligible for the entire supplement, whereas proxy respondents were only eligible for certain items. Information was collected from proxies on topics such as smoking status (items PEA1-PEA3) and the use of other tobacco-related products, such as pipes, cigars, chewing tobacco, and snuff (items PEJ1a-PEJ2a).

In addition to these smoking status and other tobacco use questions, self-respondents were queried on the following topics depending on their smoking/tobacco use status (i.e., every day, some days, or former cigarette smokers and/or users of other non-cigarette tobacco products):

• Smoking history

• Current cigarette smoking prevalence and consumption

• Type of cigarettes smoked

• Price of last pack/carton of cigarettes purchased and state where purchased

• Medical and dental advice to quit smoking

• Attempts and intentions to quit smoking cigarettes and/or other forms of tobacco use

• Workplace smoking policies and smoking rules in the home

• Attitudes toward smoking in public places

Another generally unique feature to the 2003 TUS-CPS was the administration of questions to former smokers on their previous level of addiction, products/resources/methods used to quit smoking, and advice from health professionals. This feature enables comparisons between characteristics of former smokers (or successful quitters) and current smokers attempting to quit.

Administrative information was collected on who the proxy respondents were, the language in which the interview was conducted, and the survey method (telephone vs. personal-visit interviews; Computer Assisted Telephone Interviewing (CATI) vs. Computer Assisted Personal Interviewing (CAPI)). Demographic information collected include age, sex, race, Hispanic origin, marital status, veteran status, educational attainment, family relationship, occupation, and income.

A rare disease is one that affects fewer than 200,000 people in the United States. Because few people have these diseases, clinical studies on treatments can be hard to conduct. One way to study rare disease treatments is with an snSMART study.

snSMART studies have two stages. In the first stage, researchers assign patients to a treatment by chance. In the second stage, patients may stay with the same treatment or switch treatments. Patients stay on the same treatment if it's working well. If the treatment isn't working, researchers assign patients by chance to a new treatment.

snSMARTs can help researchers learn more from a smaller number of patients than a standard clinical study. But most current methods for analyzing snSMARTs use data only from the first stage, which can lead to inefficient results.

In this project, the research team developed and tested new methods that use data from both stages to analyze snSMARTs. The team compared results from the new methods to actual treatment effectiveness to see Bias, or whether results are too high or too low effficiency, or how big the difference is between the results and actual treatment effectiveness

Clinical practice guidelines help doctors decide on treatments to recommend for their patients. Guidelines are based on research that looks at the benefits and harms of different treatments. Patient and caregiver input can improve the usefulness of guidelines. But guideline developers often rely on the input of only a few patients and caregivers.

In this study, the research team created a process for getting feedback on guidelines from larger groups of patients and caregivers. This process is called the RAND/PPMD Patient-Centeredness Method, or RPM. The team tested RPM with guidelines for Duchenne muscular dystrophy, or DMD. DMD is a severe form of muscle loss that mostly affects young boys.

The Eurobarometer series is a unique cross-national and cross-temporal survey program conducted on behalf of the European Commission. These surveys regularly monitor public opinion in the European Union (EU) member countries and consist of standard modules and special topic modules. The standard modules address attitudes towards European unification, institutions and policies, measurements for general socio-political orientations, as well as respondent and household demographics. The special topic modules address such topics as agriculture, education, natural environment and resources, public health, public safety and crime, and science and technology.

This round of Eurobarometer surveys diverged from the Standard Eurobarometer measures and queried respondents on the following major areas of focus: (1) the European Parliament (EP), (2) energy supply, (3) data protection and electronic identity, (4) chemical labeling, and (5) rare diseases. For the first major area of focus, the European Parliament, respondents were asked about their knowledge and opinion of the EP, whether the EP should play a more important or less important role, which policies should be given priority by the EP, and which values should be defended by the EP. For the second major area of focus, energy supply, respondents were queried about what goals should be prioritized in energy policies, what energy policies should be adopted, and whether or not there should be a communal European Union (EU) energy policy. Additionally, respondents were asked whether they believed it was in their country's energy security interest to assist other EU member states facing energy supply problems, as well as whether they believed it was desirable that their country provide assistance to other EU member states in the name of European solidarity. For the third major area of focus, questions address activities one performs on the Internet, opinions about types of information and data considered to be personal, types of information disclosed on social networking and online shopping sites and the risks, and measures taken to protect one's identity. Opinions were also collected on how personal information and data are acquired, treated, stored and protected by public and private organizations. For the fourth major area of focus, chemical labeling, respondents were asked about their use and perception of chemical products in various circumstances, how they determine whether or not a chemical product is hazardous, what the proper handling of chemical products is, where respondents find information about the potential dangers of chemical products, who to trust for information about chemical product safety, and whether or not they could correctly identify chemical product warning labels. For the fifth major area of focus, rare diseases, respondents were interviewed about what they believe rare diseases are, whether or not they knew or heard of someone with a rare disease, what society should do about rare diseases, what specific policy responses to rare diseases should be implemented by national health services and the EU as a whole, as well as whether or not they had heard of certain rare diseases.

Demographic and other background information collected includes age, gender, nationality, marital status and parental relations, left-right political self-placement, occupation, age when stopped full-time education, household composition, ownership of a fixed or a mobile telephone, difficulties in paying bills, level in society, and Internet use. In addition, country-specific data includes type and size of locality, region of residence, and language of interview (select countries).

The Great Smoky Mountain Study (GSMS) is a longitudinal epidemiological study of 1,420 children begun in 1992 in 11 rural counties in western North Carolina. Originally, the study had three aims: 1) to estimate the prevalence of common psychiatric disorders; 2) to study their development over time; and 3) to determine the level of mental health service use. The study expanded over time to include correlates and predictors of substance abuse and psychiatric problems. The study continued for over 20 years, with the original participants assessed up to 11 times from ages 9 to 30 (over 11,000 assessments total).

This collection includes data from study modules related to alcohol, cannabis, and depressive disorders in addition to core data on participants. This core data includes demographic variables related to age, sex, socioeconomic status, and race.
