Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa [HAALSI]: Agincourt, South Africa, 2015-2022 (ICPSR 36633)

Released/updated on: 2023-03-13

Geographic coverage: Africa, South Africa, Global

Time period: 2014-01-01--2015-01-01, 2018-01-01--2019-01-01, 2021-01-01--2022-01-01

The Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa (HAALSI) study is a population-based survey that aims to examine and characterize a population of older men and women in rural South Africa with respect to health, physical and cognitive function, aging, and well-being, in harmonization with other Health and Retirement Studies.

The baseline survey was conducted among 5,059 men and women aged 40 years or older, who were sampled from within the existing framework of the Agincourt health and socio-demographic surveillance system (AHDSS), in rural Mpumalanga province, South Africa. Survey data were collected on cognitive and physical functioning, social networks, cardiometabolic disease and risk factors, HIV and HIV risk, and economic well-being. The survey also included anthropometric measures and point-of-care blood tests for hemoglobin, glucose and lipids. Dried bloodspots (DBS) were collected at the survey and later tested for HIV, HIV viral load, glucose and CRP. A sub-sample had more extensive laboratory follow-up testing, which will be available in future data releases. A second wave of the survey was administered in 2018 through 2019, and a third wave of the survey was administered in 2021 through 2022.

Demographic information includes age, sex, income, education, marital status, number of children, and employment.

Harvard dataverse hosts an additional restricted-use dataset which compliments this collection, the HAALSI Baseline HIV Biomarker Data; users interested in obtaining these data must request access based on the terms outlined in the data use agreement.

HIV Transmission Network Metastudy Project: An Archive of Data From Eight Network Studies, 1988--2001 (ICPSR 22140)

Released/updated on: 2011-08-09

Geographic coverage: Manitoba, United States, Brooklyn, Flagstaff, New York (state), Global, Canada, Baltimore, Atlanta, Texas, Colorado, Georgia, Maryland, Colorado Springs, Arizona, Houston

Time period: 1988-01-01--2001-01-01

The purpose of this project was to establish a collection of datasets that could be used (1) to analyze the influence of partnership networks on the transmission of sexually transmitted and blood-borne infections, and (2) to examine the influence of study design on estimation of network properties and impacts. Eight studies contributed datasets to the collection.

They include:

Colorado Springs Project 90, 1988-1992
Bushwick [Brooklyn, NY] Social Factors and HIV Risk (SFHR) Study, 1991-1993
Atlanta Urban Networks Project, 1996-1999
Flagstaff Rural Network Study, 1996-1998
Atlanta Antiretroviral Adherence Study, 1998-2001
Houston Risk Networks Study, 1997-1998
Baltimore SHIELD (Self-Help in Eliminating Life-Threatening Diseases), 1997-1999
Manitoba Chlamydia Study, 1997-1998

Each study contains information on sexual, needle sharing, and/or social networks. Each dataset was harmonized to permit comparative analysis. Almost all of the studies were research projects funded by federal agency sources (e.g., United States Centers for Disease Control and the National Institutes of Health); one was funded by Canadian sources. These studies, all closed for further enrollment, provide a range of designs and study types as well as a range of transmitted diseases. This allows researchers to investigate the relative effect of personal behavior and network connections on the dynamics of disease transmission, and to explore the impact of sampling design on estimation of network properties. Respondents were asked questions about different test results such as HIV, chlamydia, syphilis and hepatitis. Demographic variables include race, ethnicity, marital status, age, and gender.

Kenya Democratization Survey Project, 2006 (ICPSR 32041)

Released/updated on: 2011-10-13

Geographic coverage: Africa, Kenya, Global

Time period: 2006-05-29--2006-07-04

The Kenya Democratization Survey Project was designed to measure societal support for various constitutional reform proposals, support for the government under President Mwai Kibaki, and trust in the government more generally. The project attempts to measure the attitudes of Kenyan citizens on the democratization process during 2005-2006 period and assess the interplay between ethnicity, attitudes on constitutional reform, the economy, and foreign influence in Kenya. The survey consisted of three parts, Part I: Demographic Information, Part II: Political Perceptions, and Part III: Economic Perceptions and Land Reform. Part I provides variables including gender, marital status, number of wives if married, whether they live in an urban or rural area, native language, ethnicity, religion, highest level of education, and occupation. Part II includes questions pertaining to respondents interest in public affairs, satisfaction with Kenya's democracy, party identification, view of the current constitution's reflection of the values of the Kenyan people, how often the President ignores the constitution, trust in government institutions, perception of public officials' involvement in corruption, the level of respondent approval regarding the government's performance, respondent's view on the government's power, their opinion on changing or keeping the current constitution and on political reform, and the degree of their satisfaction with the current government's constitutional reform process. Part III contains questions concerning the respondent's rating of economic conditions (present and past), their rating of living conditions (present, past, and future), their level of occurrence having gone without basic necessities (such as food, water, medicines or medical treatment, fuel, and cash income), their view on land ownership by foreigners and women, and land seizure and arbitration by the government, their opinion of women holding political office, their stance on the local court's authority to protect local religious practices, their opinion on local religious courts ruling on issues such as marriage and divorce, and whether respondents or family members are HIV positive. In addition, respondents were asked whether they read the newly proposed constitution, and if and how they voted in the November 21, 2005 referendum.

Perception and Memory Experiments Using Drug Names [2010, Canada] (ICPSR 34122)

Released/updated on: 2013-04-30

Geographic coverage: Canada, Ontario, Global

Time period: 2012-03-28--2012-03-29, 2012-07-05--2012-07-06

Drug names that look and sound alike are a leading cause of medication errors (e.g., diazepam and diltiazem, hydroxyzine and hydralazine, Paxil and Taxol, fomepizole and omeprazole, Foradil and Toradol). Observational studies of dispensing in outpatient pharmacies suggest that the rate of wrong drug errors -- the type most likely to be the result of name confusion -- is roughly 0.13 percent. With 3.9 billion prescriptions dispensed in 2009, that translates to 5 million wrong drug errors per year in the United States. The purpose of this overall project was to develop, demonstrate, and disseminate a standard protocol for pre-approval testing of drug names, including a standard battery of psycholinguistic tests and data analytic methods, all with comparison to control names and to refine and demonstrate analytic methods by conducting a series of visual perception, auditory perception, and short term memory experiments using drug names as stimuli. The achievement of this aim will provide both regulators and pharmaceutical manufacturers with a scientifically validated, step-by-step method for testing new drug names for confusability. The data for this collection come from four experiments. In each experiment, participants are tested on their ability to correctly identify drug names under four conditions (see study design). Variables include participant reaction time to identify drug names and the percent participants correctly or incorrectly identified drug names. Study participants include medical doctors, nurse practitioners, pharmacists, and pharmacy technicians. Other variables include participant gender, education degree held, primary language spoken, and employment location.

SABE - Survey on Health, Well-Being, and Aging in Latin America and the Caribbean, 2000 (ICPSR 3546)

Released/updated on: 2006-02-17

Geographic coverage: Cuba, Argentina, Barbados, Uruguay, Brazil, Mexico, Chile, Global

Time period: 1999-01-01--2000-01-01

The Survey on Health, Well-Being, and Aging in Latin America and the Caribbean (Project SABE) was conducted during 1999 and 2000 to examine health conditions and functional limitations of persons aged 60 and older in the countries of Argentina, Barbados, Brazil, Chile, Cuba, Mexico, and Uruguay, with special focus on persons over 80 years of age. Project SABE was administered in the official language of each country: Spanish in Buenos Aires (Argentina), Mexico City (Mexico), Santiago (Chile), Havana (Cuba), and Montevideo (Uruguay), English in Bridgetown (Barbados), and Portuguese in Sao Paulo (Brazil). Goals of the project were to (a) describe the health conditions of older adults (aged 60 and older with special focus on persons over 80) with regard to chronic and acute diseases, disability, and physical and mental impairment, (b) evaluate the extent to which older adults used and had access to health care services, including services that are outside the formal system (local healers, traditional medicine), (c) evaluate the proportional contribution by principal sources of support -- relatives and family networks, public assistance, and private resources (income, assets) -- towards meeting the health-related needs of older adults, (d) evaluate access to health insurance offered by private organizations, governmental institutions, and mixed systems, as well as the extent to which that insurance was actually used, (e) analyze the differentials in the self-evaluation of health conditions, access to health care, and sources of support with regard to socioeconomic group, gender, and birth cohort, (f) evaluate the relationships between strategic factors -- health-related behavior, occupational background, socioeconomic status, gender, and cohort -- and health conditions, according to the health evaluation at the time of the survey, and (g) carry out comparative analyses in countries that share similar characteristics but that differ with regard to such factors as the role of family support, public assistance, access to health services, and health-related behavior and exposure to risk. Demographic variables include age, sex, race, level of education, birthplace, religion, ethnic group, marital status, and income. Also examined were cognitive status, health status, functional status, nutritional status, and use and accessibility of services

WHO Study on Global AGEing and Adult Health (SAGE): Wave 0, 2002-2004 (ICPSR 28502)

Released/updated on: 2013-11-15

Geographic coverage: China (Peoples Republic), South Africa, Mexico, Ghana, Global, India, Russia

Time period: 2002-01-01--2004-01-01

The World Health Organization (WHO)'s Study on Global Ageing and Adult Health (SAGE) is a longitudinal follow-up of a cohort of ageing and older adults. SAGE has been built on the experience and standardized instruments of WHO's 2000/2001 Multi-country Survey Study (MCSS) and the 2002/2004 World Health Surveys (WHS). These surveys focused on health and health-related outcomes and their determinants and impacts in nationally representative samples. These data aim to address data gaps on ageing, adult health and well-being in lower and middle income countries, whilst being comparable to surveys conducted in higher income countries (such as the Health and Retirement Study (HRS), English Longitudinal Study of Ageing (ELSA), and the Survey of Health, Ageing and Retirement in Europe (SHARE)). One of the major drivers of this effort has been the lack of comparability of self-reported health status in international health surveys due to systematic biases in reporting, despite using similar instruments and attempts at making questions conceptually equivalent in translation. SAGE uses standard instruments developed over the last decade, a common design and training approach with explicit strategies for making data comparable to cover a wide range of issues that directly and indirectly impact health and well-being. The survey methodology and research design has included a number of methods to address methods for detecting and correcting for systematic reporting biases in health interview surveys, including vignette methodologies, objective performance tests and biomarkers. A number of techniques have also been employed to improve data comparability, including using common definitions of concepts, common methods of data collection and translations, rigorous sample design and post hoc harmonization. The 2002-2004 WHS data from six countries (China, Ghana, India, Mexico, Russia, and South Africa) constitute Wave 0 of WHO's Study on Global Ageing and Adult Health (SAGE). A sample of these respondents were included in the follow-up 2007-2010 SAGE Wave 1 in these six countries, with new respondents added to ensure a nationally representative sample.
