Twin epidemics: the effects of HIV and systolic blood pressure on mortality risk in rural South Africa, 2010-2019. BMC Public Health 22 (1):387. DOI: 10.1186\/s12889-022-12791-z. PMID: 35209881; PMCID: PMC8866551.\n\nThe HIVafter40_Twin_Epidemics_HIV_NCD data was created as part of the HIVafter40 project, the successor to the Ha Nakekela Project, both nested within the Agincourt Health and socio-Demographic System (AHDSS) located in Northeastern South Africa.The projects use mixed methods to measure prevalence and incidence of HIV and NCDs, investigate health and sexual behaviours, and study how people have coped with the abrupt introduction of a new and deadly health threat and efforts to prevent and ameliorate it. The overall goal of HIVafter40 is to examine life course and contextual variation in HIV risk and protective behaviors and mortality in a rural sub-Saharan African population.\nThe AHDSS has, since 1992, collected an annual census from households in a defined geographic area of Mpumalanga Province. The 2009 census served as the sampling frame for the 2011 Ha Nakekela Project. The AHDSS provides rapid measures of vital statistics and is the basis of a wide range of more detailed studies. As of June 2018, the study site consisted of 31 villages with a population of 116,549 people, living in 22,721 households. Further information is available at <https:\/\/www.agincourt.co.za\/> and specifically for census data collection, at <https:\/\/www.agincourt.co.za\/?page_id=1805>\n\nThe Ha Nakekela project undertook two data collection efforts:\n1. The Ha Nakekela Survey\nThis survey  is based on an age\/sex stratified sample of respondents in the 2009 AHDSS Census. Carried out in 2010-11, the cross-sectional survey included 5,080 respondents, of whom 2,080 are aged 40 - 93. It has 3 parts:\nBehavioral Risk Assessment (based on BERIS Sexual Behavior Questionnaire)\nChronic Disease Risk Factor Surveillance (based on STEPS Health Risk Questionnaire)\nHIV and Non-Communicable Disease (NCD) biometric data\n2. The Izindaba za Badala (Matters that Concern Older People) \nThis Study (IZB) is nested within the Ha Nakekela Survey. It consisted of three related interview studies carried out in 2013:\n IZB Life History Interviews: 60 life history interviews with people with and without HIV aged 40-84 who participated in the Ha Nakekela Survey\nIZB Community Focus Group Interviews: 9 community focus group interviews with a total of 77 respondents \nIZB Key informant Interviews: 9 health workers interviews in 3 local health clinics\n\nThe HIVafter40 project added two follow-up data files:\na. AHDSS_Ha_Nakekela_HIV_Hyp_Sample.dta \nThis data file contains information on the Ha Nakekela sample in which individuals were linked to their location\/outcome reports in successive AHDSS censuses through 2020. This dataset permits examination of mortality in the nine years subsequent to participation in the Ha Nakekela Survey. HIVafter40_Twin_Epidemics_HIV_NCD.dta is a subset of this dataset.\nb. Izindaba za Badala Round 2\nIZB Life History Interviews: 25 in-depth follow-up interviews in 2018 \nIZB Community Focus Group Interviews: 10 community focus group interviews with a total of 84 participants in 2018 \nIZB Key informant Interviews (cancelled due to the COVID-19 epidemic):10 community focus group interviews with a total of 84 participants planned for 2020. \n\nThe website https:\/\/hivafter40.princeton.edu\/ is regularly updated and contains the most complete information on the projects.","coll_dates":[{"start":"2010","end":"2019","cycle":""}],"nation":[{"name":"South Africa","abbreviation":""}],"geog_coverage":"The study was conducted in the Agincourt Health and socio-Demographic System (AHDSS) site located in Mpumulanga Province, Northeastern South Africa.","geog_unit":"The data is at the level of Village.","analysis_unit":"Individuals","data_kind":"Survey data","notes":"The projects measured prevalence and incidence of HIV and NCDs, and investigated health and sexual behaviours, as well as how people have coped with the abrupt introduction of a new and deadly health threat and efforts to prevent and ameliorate it.
