Boston City Hospital Maternal Health Habits Project, 1984-87
Investigators: Barry Zuckerman, Ralph Hingson, Deborah Frank and Hortensia Amaro
The 1984-87 Boston City Hospital Maternal Health Habits Project was conducted as part of an ongoing study of maternal health behaviors, psychosocial characteristics, and pregnancy outcomes. The study was designed to investigate the effects on infants of various prenatal factors, including the use of alcohol, cigarettes, and illicit drugs; violence; emotional well-being; social support; and life experiences. Subjects were continuously recruited from the Women's and Adolescent Prenatal Clinics of Boston City Hospital from July 1984 through June 1987. English- and Spanish-speaking women who were willing to give informed consent and who gave birth by December 31, 1987 were eligible to participate in the study. Participants were interviewed at least twice — once during the prenatal period at the time of registration in the study and again during the immediate postpartum period. A subset of the participants were also interviewed at 32 to 36 weeks into the pregnancy. Prenatal and postpartum interviews obtained information on patterns of use of cigarettes, alcohol, marijuana, cocaine, and psychoactive drugs; participants' demographic and psychosocial characteristics; and participants' reproductive and general medical histories. Also, at the time of interviews, participants submitted urine samples to be used for drug testing. After delivery, information documenting reproductive and medical histories, prenatal and intrapartum risk factors, and weight gain during pregnancy was abstracted from mothers' medical records. Infants were examined within 8 to 72 hours of delivery by a physician who was blinded to the mothers' prenatal histories.
Boston City Hospital Study on Neonatal Outcome, 1977-1979
Investigators: Barry Zuckerman & Suzette Levenson
A study of maternal health and fetal development at Boston City Hospital provided an opportunity to explore whether infants born to adolescents exhibit poorer outcomes at birth than infants born to nonadolescents, and if the outcomes are poorer, whether adolescent status or other health habits or life situations are more predictive of those outcomes. This study was set up to assess whether adolescent and nonadolescent mothers varied on numerous maternal characteristics, labor and delivery events, and neonatal outcome measures. Outcome variables examined included length of gestation, infant size at delivery, and Apgar scores. The independent variables were: drug use (never, prepregnancy, or during pregnancy), prepregnancy weight, number of previous pregnancies, religious affiliation, race, history of prior maternal illnesses (e.g., hypertension, diabetes), number of miscarriages and abortions, risk factors (e.g., toxemia, epilepsy, anemia, accidents) during pregnancy, weight change during pregnancy, time of first prenatal visit (first, second, or third trimesters, or no prenatal care), daily coffee consumption, x-ray exposure during pregnancy, number of cigarettes smoked per day during pregnancy, marijuana use (never, prepregnancy, pre- and during pregnancy), education, number of meals per day, sex of infant, alcohol consumption (average daily drinks) prior to pregnancy and during pregnancy separately, and iron use. Additional variables include: whether the mother had premature rupture of the membrane, a Cesarian section, meconiumstained fluid, oxytocin (Pitocin)-induced labor, medications during labor, use and route of anesthesia, maternal fever, whether the infant had an abnormal presentation, or abnormal placenta, nuchal cord, decelerations, intubation, and forceps extraction. Further data on infant status, including congenital malformations and weight at birth, were also added.
California Adolescent Health Data Set 2013
Investigators: California Adolescent Health Collaborative
The California Adolescent Health Data Set is a collection of California-wide and county-specific data about the health status of adolescents. Data for each variable was extracted and compiled from public access databases, including vital and hospital records, administrative data, and statewide surveys. Some of the primary sources were the California Department of Finance, California Department of Public Health, California Department of Education, California Health Interview Survey (CHIS), and California Healthy Kids Survey (CHKS). The raw data from these sources were collected and calculated in different ways. Data may be derived from population surveys (e.g., demographic numbers from the Census), medical records (e.g., injury data from hospital records), or representative sample surveys (e.g., measures of risk behaviors). To be included, data had to be available at the county level, collected over time and available for individuals within the age range of 10-24. In addition, data on each indicator had to provide a statistically stable population level estimate. For example, there may not be a sufficient number of survey respondents to calculate an accurate measure for the adolescent population in counties with small populations. In such cases, counties are grouped together. Where applicable, 95% confidence intervals are included for data points. The confidence intervals take into account error in measurement to provide a statistically accurate estimate of the possible range of values for a specific indicator. Adolescent health providers and professionals need data to inform their work, but data on adolescent health can be difficult or time consuming to retrieve. Therefore, the California Adolescent Health Data Set is designed to be accessible, practical, and easy to use for health department staff, providers, policy makers, community leaders, educators, and advocates. The California Adolescent Health Data Set is a resource for education, assessment and evaluation, program development or implementation, and advocacy.
California Perinatal Substance Exposure Study, 1992
Investigators: William A. Vega
This epidemiologic cross-sectional survey was conducted in order to obtain a 1992 estimate of prevalence of prenatal drug exposure by specific drug type for both the State of California as a whole and for the major regions within the state. Several other goals of the research included contrasting perinatal substance exposure prevalence for a variety of subgroups, including geographic region, socioeconomic level, race/ethnicity, and other sociodemographic factors. There was also interest in conducting a risk factor analysis to identify profiles of risk for individual-level perinatal substance exposure in California. It was hoped that data produced by this study would provide an accurate population-based estimates of the number of substance-exposed infants born in California, and thereby provide a basis for future studies, program evaluations, and clinical- and community-based interventions. Urine specimens and demographic information were collected anonymously from 29,494 pregnant women admitted for delivery in 202 maternity hospitals throughout the state between March and October, 1992. This study, which represents the largest survey of perinatal substance exposure reported to date, assessed 46 variables across 29,494 cases.
California Survey of AIDS Knowledge, Attitudes & Behavior 1987
Investigators: State of California, Dept. of Health Services, Office of AIDS
The California Survey of AIDS Knowledge, Attitudes and Behavior: 1987 gathered data through a survey of California adults for the purpose of forecasting the course of the AIDS epidemic and planning risk reduction programs in the State of California. Augmented data collection was employed for three risk-groups: (1) gay-identifying men, (2) multiple/high-risk partner heterosexuals, and (3) recreational drug users. Interviews were conducted from October 4, 1987 through December 20, 1987. The 1988 follow-up study to the California Survey of AIDS Knowledge, Attitudes and Behavior: 1987 has been archived as Sociometrics AIDS/STI Data Archive Dataset 02. The 1987 data collection program had eight major objectives: To gather population-based data bearing on the size of the three primary AIDS risk groups in the State of California: homosexual/bisexual men, IV drug users, and multiple/high-risk partner heterosexuals; To determine the basic socioeconomic and other demographic characteristics of these risk groups in order to both enhance general understanding and allow for sufficient audience analysis to develop effective risk reduction interventions; To ascertain AIDS awareness and information levels among risk groups, as well as determining the impact of the epidemic to date on sexual and other risk behaviors; To determine the incidence of specific risk behaviors among the risk groups, including unsafe sex practices, IV drug usage, and needle-sharing; and collect baseline information that would enable behavior change over time to be monitored; To measure the degree to which existing risk reduction programs have penetrated risk group audiences in the State of California, which will be useful in evaluating the effectiveness of such programs; To collect data bearing on the design of future risk reduction programs, including questions related to message definition and the selection of appropriate communication channels; To determine AIDS awareness and knowledge levels among the general (low-risk) population of the state of California; and To gather population based data on utilization of the health care delivery system in California. Interviews were conducted from October 4, 1987 through December 20, 1987. The completion rate for interviews was 71%. Interviews were conducted in two stages. An initial 15-minute interview determined whether a respondent was a member of one or more of three AIDS high-risk groups: gay-identifying men, multiple/high-risk partner heterosexuals, or recreational drug users (not limited to intravenous drug use). If a respondent qualified as high-risk, an additional battery of questions, lasting about 20 minutes, was administered.
California Survey of AIDS Knowledge, Attitudes & Behavior: 1988
Investigators: State of California, Dept. of Health Services, Office of AIDS
The California Survey of AIDS Knowledge, Attitudes and Behavior: 1988 gathered data on 311 variables through a telephone survey of California adults for the purpose of forecasting the course of the AIDS epidemic and planning risk reduction programs in the State of California. The study consisted of 4,661 telephone interviews with a household probability sample of California adults aged 18 and over. Data collection employed stratified random sampling with over-sampling in geographic areas with identified high risk-group populations. Augmented data collection was employed for three risk-groups: (1) gay-identifying men, (2) multiple/high-risk partner heterosexuals, and (3) recreational drug users. Interviews were conducted from September 30, 1988 through December 13, 1988. Data collected in this survey permit comparisons to the California Survey of AIDS Knowledge, Attitudes and Behavior, (KABB), conducted in 1987, which has been archived as Sociometrics AIDS/STI Data Archive Dataset 01. However, the population stratification design employed in 1987 differed from that utilized in 1988, and some differences in results between the surveys may be attributable to this variation in methodology. The 1988 data collection program had four major objectives: To increase the number of risk group cases on whom reliable survey data existed in order to facilitate more detailed analysis of attitudinal and behavioral trends; To assess change or continuity in the incidence and distribution of AIDS risk behaviors over the year between the 1987 KABB survey and the 1988 KABB survey; To assess change or continuity in knowledge levels and attitudes of high-risk individuals between the two surveys; To measure the effectiveness of recent educational initiatives in California, including the national household mailing conducted by the Surgeon General of the United States.
Cambridge City over-75s Cohort Study (CC75C): 1985 - 2007, Version 3.0
Investigators: Department of Public Health and Primary Care, University of Cambridge
The Cambridge City over-75s Cohort Study (CC75C), a longitudinal population-based study of cognition and function in advanced old age, began in 1985 from a survey of over 2,000 men and women aged 75 years and older in Cambridge, United Kingdom (UK). It is one of the largest and longest-running observational studies of aging, as well as one of the first and largest prevalence studies of dementia and its sub-types to be conducted in the UK. The CC75C study originated in the mid-1980s as a survey of dementia prevalence called the Hughes Hall Project for Later Life. This initial study comprised 2,610 men and women aged 75 years and older at enrolment (1985-1987) who were registered with a selection of geographically and socially representative general practices in Cambridge, UK. The sample.s age specific gender distribution and residential status closely matched national population data for that period. From this initial survey of 2,610 people, a baseline sample of 2,166 individuals was selected for the longitudinal cohort. To date, a total of seven interview waves have been completed with survivors and proxy informants. The population has been followed-up to a very advanced age, and the study plans to follow-up individuals until the cohort has no living members. Sociometrics has archived a subset of variables collected from the seven interview waves (data set version 3.0). These variables include demographic variables (age, sex, marital status, education level, type of accommodation), social contacts, service contacts, physical conditions that interfere with day-to-day tasks, activities of daily living (ADL) and instrumental activities of daily living (IADL). This User.s Guide contains detailed information about 127 distinct variables administered to the 2,610 respondents in the full original sample 2,610 respondents and to the 2,166 respondents followed through interview waves 1 through 7.
Census Tracts/BNAs, 1970, 1980, 1990
Investigators: National Opinion Research Center & the Urban Institute, Washington, DC
Census Tracts and BNAs are small, relatively permanent statistical subdivisions of a county. . Census tracts are delineated for all metropolitan areas and other densely populated counties by local census statistical areas committees following Census Bureau guidelines. Census tracts usually have between 2,500 and 8,000 persons and when first delineated, were designed to be homogeneous with respect to population and characteristics, economic status, and living conditions. Census tracts do not cross state or county boundaries. In all but a very small number of cases in New England, census tracts do not cross metropolitan area boundaries. Census tracts are the basic statistical reporting unit in metropolitan areas: block numbering areas (or BNAs) are analogues to census tracts in non-metropolitan area counties and remote rural areas. It is an area that has been "blocked" by the census but is not tracted, and the Census Bureau in most respects treats the tract and BNA data as a single level of aggregation. BNAs are drawn using guidelines similar to those for the delineation of census tracts. As with census tracts, BNAs do not cross county or state boundaries. This dataset includes socio-economic and demographic data for all census tracts/BNAs in the US. B1 consists of data from the 1970 Census, and has 36,312 cases and 680 variables. B2 covers data from the 1980 Census, and includes 878 variables for 46,520 cases. B3-B4 covers data from the 1990 Census and includes 1,021 variables for 61,258 cases.
Chicago Urban League 1979 Young Chicagoans Survey
Investigators: Dennis Hogan and Evelyn Kitagawa
This study examined the demographic, social, economic and fertility characteristics of black teenage girls residing in the City of Chicago in 1979. The study sample consisted of 1,078 black female respondents aged 13-19 selected to comprise two randomly drawn two-stage area probability samples of Chicago households. The two independent samples included 388 respondents from Chicago, and 690 respondents from surrounding poor areas. The survey non-response rate was less than 10%. All data were collected through personal interviews by female interviewers. Information was obtained regarding age at first coital experience, marriage, pregnancy and childbirth, as well as basic background information (e.g., marital status, religion, education, employment status, and family income). Note for users of DAAPPP Data Sets #01-B1DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only. Most of these datasets contain SPSS syntax files that use Job Control Language (JCL) from 1980s versions of SPSS-X. Because the syntax is old, the syntax files require editing to conform to the current syntax standards used by SPSS/Windows or SPSS/Unix.

Child Health Supplement to the National Health Interview Survey, 1981
Investigators: National Center for Health Statistics
The National Health Interview Survey (NHIS) was designed to provide national data on the incidence of acute illness and accidental injuries, chronic conditions and impairments, disabilities, the utilization of health care services, and other health-related topics. In 1981, after several years of planning and preparation, a comprehensive supplement on children was included with the survey. One child from each eligible household was randomly selected, and data collected on a nationwide probability sample of 15,416 children 17 years of age and under. Questionnaire topics included family structure, child care arrangements, breastfeeding, motor and social development, medications, birth and prenatal events, lifetime hospitalizations and surgery, chronic conditions, weight, eyes and teeth, school attendance and performance, behavior problems, social effects of ill health, and sleep habits. Additional data about health and medical care were also collected as part of the core NHIS questionnaire. In all there are 1,416 variables in the Data Set. This Data Set should prove particularly useful as a baseline national sample for comparisons with smaller or more specialized samples. The microcomputer version of the raw data is an extract of 1,028 cases. Note for users of DAAPPP Data Sets #01-B1DAAPPP data sets 01 through B1 are comprised of a User's Guide, SPSS syntax files (*.SPS or *.SPX) and raw data files only.
