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 The 1988 follow-up study to the California Survey of AIDS Knowledge, Attitudes and Behavior: 1987 has been archived as Sociometrics AIDS/STI Data Archive Dataset 02.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.

Clients of the Certified Nurse Midwifery Program of Maternal and Family Health Services in Wilkes-Barre, Pennsylvania, 1982-1986

Investigators: Charles LaJeunesse, Mary Louise Schaefer, and Connie McNunis

The AFL Demonstration Program was enacted to provide local communities and institutions with workable models of prevention programs that discourage premarital adolescent sexual relations and care programs that reduce the negative consequences of adolescent pregnancy. To develop these models, AFL authorized grants for three types of demonstrations: (1) projects which provide "care services" only (i.e., services for the provision of comprehensive services to pregnant adolescents, adolescent parents, and their families); (2) projects which provide "prevention services" only (i.e., services to promote abstinence from adolescent premarital sexual relations); and (3) projects which provide a combination of care and prevention services. The demonstration projects were multi-year projects (3 to 5 years), renewable annually. As of March 1988, 97 demonstration projects had been funded. Each demonstration project has an internal evaluation component designed to test hypotheses specific to that project's service delivery model. Projects were evaluated by an independent evaluator contracted by each grantee. Evaluators were usually affiliated with a college or university in the grantee's state. Data Set B9 was collected as an evaluation of the Certified Nursing Midwifery (CNM) Program of the Maternal & Family Health Services, Inc., in Wilkes-Barre, Pennsylvania. The project began in October 1982 with Adolescent Family Life care program funding. The project provides care services to a predominantly white population of pregnant and parenting adolescents. In this evaluation, the hospital-based outpatient care program with a Health Visitor component is compared with the hospital-based project clinic operation before the Health Visitor component was given a major role. The evaluation focuses on teen pregnancy outcomes and postnatal care. The data cover clients registered from April 1982 through May 1986 and have been divided into two periods. The pre-treatment, or comparison group, covers April 1982 through August 1983; the treatment, or study group, covers February 1984 through May 1986. In the comparison group, the role of the Health Visitor was minimal; usually the Health Visitor became involved only after the birth of the child. In the study group, the Health Visitor became involved early on in the pregnancy and had a much more comprehensive role. The project offers pregnancy testing, prenatal and postpartum health care, nutritional and social services counseling, as well as the Health Visitor program. Although services are provided to male partners and family members as well, the data contain information only regarding the pregnant or parenting female adolescent. The surveys included questions on respondent demographic characteristics, pregnancy and childbirth history, contraceptive methods and behaviors, medical complications, pregnancy risk factors, delivery complications, and program involvement at different follow-up periods. The actual intervention of the program is as follows. All new clients are given a pamphlet on adoption at their first prenatal visit (see Appendix D). The pamphlet was developed by the project to introduce adolescents to adoption and to invite their exploration of this option. A Health Visitor provided support and counseling through the baby's first birthday. The Health Visitor contacts included clinic and hospital visits, telephone calls, family planning and well-baby visits, and home visits. In the comparison group, the Health Visitor was to have contact with the client at least four times--in the hospital directly after delivery, 4 weeks after delivery, 6 months after delivery, and 12 months after delivery. In the study group, Health Visitors were to become involved with pregnant adolescents early in the pregnancy. The Health Visitor had contact with the client at her first visit to the clinic, when she was 5 months pregnant, at delivery, and at 6 weeks, 3 months, 6 months, and 12 months after delivery, as well as at any time the pregnant or parenting adolescent was in need of the Health Visitor's services. The role of Health Visitors is to encourage and assist young parents to remain in or return to school; make use of family planning methods; enroll in vocational classes or a job training program; learn about baby care, budgeting, and meal preparation; and secure housing, WIC, and financial assistance. By establishing a solid bond with the client prior to delivery, the Health Visitor lays the foundation for an ongoing relationship. An advisory committee, consisting in part of pregnant and parenting adolescents and their family members, meets regularly to provide feedback to the project on its services. As a result of the committee's recommendations, the project added parenting classes, which grandparents and fathers were also invited to attend, to its services.
