description: 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. 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.
description: ICPSR data undergo a confidentiality review and are altered when necessary to limit the risk of disclosure. ICPSR also routinely creates ready-to-go data files along with setups in the major statistical software formats as well as standard codebooks to accompany the data. In addition to these procedures, ICPSR performed the following processing steps for this data collection: Created variable labels and/or value labels.; Checked for undocumented or out-of-range codes..
description: Response Rates: The response rate was 86% after excluding sampled individuals who had died or permanently out-migrated from the study site.

description: Participants were sampled from the existing framework of the Agincourt Health and Socio-Demographic Surveillance System (AHDSS) site in Mpumalanga province. Individuals 40 years and older as of July 1, 2014 and permanently living in the study site during the 12 months previous to 2013 census round were eligible for this study. Using the full 2013 Census data, a sampling frame of 8,974 women and 3,901 men aged 40 and older who met the residence criteria were identified. Based on power calculations for key health outcomes, the target sample size was approximately 5,000 completed interviews divided equally between women and men. In order to maximize the links to data collected in prior surveys, individuals who had participated in the WHO SAGE and prior Agincourt HIV/NCD studies with 100% probability were selected. The remainder of the sample was selected randomly to reach the target. Assuming an 80% response rate, we selected a total of 6,281 women and men for the main household study.
