  • Mortality differentials between self-settled refugees and South Africans in rural South Africa

    Open AccessWonder Agbemavi, Chodziwadziwa Kabudula et al.ARTICLEConflict and Health2026

    Low- and middle-income countries (LMICs) host most of the world’s refugees but often have limited mortality information systems. Consequently, evidence on the long-term mortality trajectories of self-settled refugees and the contribution of socioeconomic disadvantage to mortality inequalities remains scarce. To examine long-term mortality patterns, cause-specific mortality and the contribution of socioeconomic status (SES) to mortality differenti…

  • The economic cost of outpatient primary care of adults with multimorbidity (HIV, diabetes, and hypertension) in rural South Africa

    Open AccessCeleste Claire Holden, Winfrida Mdewa et al.ARTICLEHealth Policy and Planning2026Referências: 34

    Sub-Saharan Africa (SSA) is experiencing an epidemiological transition where non-communicable diseases are becoming the leading cause of disability and mortality alongside infectious diseases such as HIV/AIDS. Multimorbidity, the coexistence of two or more long-term conditions, is increasing in SSA. However, the cost of managing multimorbidity is largely unknown. This study aimed to estimate the economic cost of public outpatient primary care for…

  • Cohort Prevalence Estimates Are Sensitive to Prebaseline Mortality

    Open AccessMolly Rosenberg, Erika T Beidelman et al.ARTICLEDemography2026Referências: 39

    All cohorts are conditioned on survival to a study's baseline. The validity of estimates drawn from these cohorts of survivors may be compromised if those who die prior to enrollment have different covariate structures than survivors. In this research note, we used data from the “HAALSI Cohort” (Health and Aging in Africa: A Longitudinal Study of an INDEPTH Community in South Africa) of older adults in rural South Africa and a “Mortality Cohort” …

  • Viral load dynamics among adults receiving HIV care in rural North-Eastern South Africa, 2015–2020

    Open AccessArmstrong Dzomba, Francesc Xavier Gómez-Olivé et al.ARTICLEFrontiers in Public Health2025

    Introduction: The Joint United Nations Programme on HIV/AIDS set ambitious-but-reachable targets to have 95% of HIV-positive people diagnosed, 95% on ART, and 95% virally suppressed by 2030. To address the latter, post-2016, South Africa's HIV treatment guidelines aimed to deliver maximal and durable viral load (VL) suppression through extensive antiretroviral therapy (ART) scale-up. Yet, standard suppression one-off measurement conceals viral re…

  • Changes in the provision and utilisation of health care services for chronic health conditions during the Covid-19 pandemic in rural northeast South Africa

    Open AccessChodziwadziwa Kabudula, Chodziwadziwa W Kabudula et al.ARTICLEJournal of Global Health2025

    Background: The COVID-19 pandemic has impacted the provision and utilisation of health care services with varying magnitude across settings due to spatial temporal variation in the burden of COVID-19 cases and the roll-out of local COVID-19 response policies. This study assesses changes in the provision and utilisation of health care services for three major chronic health conditions (HIV/AIDS, hypertension, and diabetes) over the pre-COVID-19 an…

  • Trajectories and predictors of HIV care retention among individuals receiving ART in rural South Africa

    Open AccessAimée Julien, Jean Juste Harrisson Bashingwa et al.ARTICLEJournal of Global Health2025

    Background: Successful retention in care of people living with HIV remains a challenge and a cornerstone of ending the epidemic. A better understanding of retention predictors could guide an evidence-based approach to target interventions. We sought to characterise HIV care retention trajectories among individuals receiving antiretroviral therapy (ART) in a rural South Africa setting, and to determine factors associated with those trajectories. M…

  • Expanded child support grant eligibility and later-life mortality among mothers in rural South Africa

    Open AccessRishika Chakraborty, Erika T Beidelman et al.ARTICLEGlobal Public Health2025

    The South African Child Support Grant (CSG) may be associated with mother's mortality via pathways linked to CSG spending, however, this relationship remains uncertain. To identify the association between CSG eligibility and mortality among mothers, we exploited exogenous variation in CSG-eligibility due to iterative age-eligibility expansions. Data were obtained from the Agincourt Health and Socio-Demographic Surveillance System. Mothers contrib…

  • The Strength of Long-Distance Ties for Aging Healthy With HIV

    Open AccessShao-Tzu Yu, Brian Houle et al.ARTICLEThe Journals of Gerontology…2025Referências: 9

    Objectives In lower-income settings with limited government-funded care, personal social networks are often the primary means by which older persons access resources and support. We tested the association between long-distance ties—ties that span greater geographical and network distances—and HIV treatment outcomes in a rural South African community with one of the largest aging populations with HIV. Methods We used data from the “Health and Agin…

  • Mortality variability and differentials by age and causes of death in rural South Africa, 1994–2018

    Open AccessBrian Houle, Chodziwadziwa Kabudula et al.ARTICLEBMJ Global Health2024

    INTRODUCTION: Understanding mortality variability by age and cause is critical to identifying intervention and prevention actions to support disadvantaged populations. We assessed mortality changes in two rural South African populations over 25 years covering pre-AIDS and peak AIDS epidemic and subsequent antiretroviral therapy (ART) availability. METHODS: Using population surveillance data from the Agincourt Health and Socio-Demographic Surveill…

  • Social support receipt as a predictor of mortality

    Open AccessDavid Kapaon, Carlos Riumallo-Herl et al.ARTICLEPLOS Global Public Health2024

    The mechanisms connecting various types of social support to mortality have been well-studied in high-income countries. However, less is known about how these relationships function in different socioeconomic contexts. We examined how four domains of social support—emotional, physical, financial, and informational—impact mortality within a sample of older adults living in a rural and resource-constrained setting. Using baseline survey and longitu…

  • Leadership, cohesion, and stress in primary care facilities and retention in chronic care in rural northeast South Africa before and during the Covid-19 pandemic

    Open AccessHannah H Leslie, Morelearnings Sibanda et al.ARTICLEJournal of Global Health2024

    Background: Human immunodeficiency virus (HIV) and hypertension are major contributors to morbidity and mortality in South Africa. Effective management of these conditions is critical to population health, yet patient management and retention varies by facility for reasons that are not fully understood. We assessed whether measures of clinic leadership, cohesion, and stress were associated with retention for HIV and hypertension in a cohort of pa…

  • Can verbal autopsies be used on a national scale? Key findings and lessons from South Africa's national cause-of-death validation study

    Open AccessMonique Maqungo, Nadine Nannan et al.ARTICLEGlobal Health Action2024

    BACKGROUND: Verbal autopsy (VA), though imperfect, serves as a vital tool to determine cause-of-death, particularly for out-of-facility deaths, but challenges persist in integrating VA into Civil Registration and Vital Statistics systems. OBJECTIVE: To describe the challenges and successes of collecting a national sample of verbal autopsy interviews in South Africa to obtain the cause of death profile in 2017/18. METHODS: We recruited next of kin…

  • Socio-Behavioural Barriers to Viral Suppression in the Older Adult Population in Rural South Africa

    Open AccessChido Chinogurei, J Manne-Goehler et al.ARTICLEAIDS and Behavior2024

    South Africa has the largest share of people living with HIV in the world and this population is ageing. The social context in which people seek HIV care is often ignored. Apart from clinical interventions, socio-behavioural factors impact successful HIV care outcomes for older adults living with HIV. We use cross-sectional data linked with demographic household surveillance data, consisting of HIV positive adults aged above 40, to identify socio…

  • Understanding Household Dynamics From the Ground Up

    Open AccessShao-Tzu Yu, Brian Houle et al.ARTICLEDemography2024Citada por: 1Referências: 73

    Investigations into household structure in low- and middle-income countries (LMICs) provide important insight into how families manage domestic life in response to resource allocation and caregiving needs during periods of rapid sociopolitical and health-related challenges. Recent evidence on household structure in many LMICs contrasts with long-standing viewpoints of worldwide convergence to a Western nuclearized household model. Here, we adopt …

    Open AccessEvelyn Thsehla, Adam Balusik et al.ARTICLEGlobal Health Action2023

    BACKGROUND: The unfinished burden of poor maternal and child health contributes to the quadruple burden of disease in South Africa with the direct and indirect effects of the COVID-19 pandemic yet to be fully documented. OBJECTIVE: To investigate the indirect effects of COVID-19 on maternal and child health in different geographical regions and relative wealth quintiles. METHODS: We estimated the effects of COVID-19 on maternal and child health f…

  • Agreement between cause of death assignment by computer-coded verbal autopsy methods and physician coding of verbal autopsy interviews in South Africa

    Open AccessPam Groenewald, Jason R Thomas et al.ARTICLEGlobal Health Action2023

    BACKGROUND: The South African national cause of death validation (NCODV 2017/18) project collected a national sample of verbal autopsies (VA) with cause of death (COD) assignment by physician-coded VA (PCVA) and computer-coded VA (CCVA). OBJECTIVE: The performance of three CCVA algorithms (InterVA-5, InSilicoVA and Tariff 2.0) in assigning a COD was compared with PCVA (reference standard). METHODS: Seven performance metrics assessed individual an…

  • Exploring the relationship between anticipated stigma and community shared concerns about HIV on defaulting from HIV care in rural South Africa

    Open AccessErica N Browne, Marie C D Stoner et al.ARTICLEStigma and Health2023

    In this sample, we found limited impact of reducing anticipated stigma and increasing shared concern about HIV on retention in care. Future studies should consider the limitations of this study by examining the influence of other sources of stigma in more detail and assessing how perceptions of stigma and concern impact the full HIV testing and care cascade

  • Understanding the effects of universal test and treat on longitudinal HIV care outcomes among South African youth

    Open AccessLindsey M Filiatreau, Jessie K Edwards et al.ARTICLEBMC Public Health2023

    Implementation of UTT yielded modest improvements in time spent on ART and virally suppressed among South African YLHIV- however, meeting UNAIDS' 95-95-95 targets remains a challenge. Retention in care and re-engagement interventions that can be implemented between diagnosis and linkage to care and between ART initiation and viral suppression (e.g., longitudinal counseling) may be particularly important to improving care outcomes among South Afri…

  • Performance evaluation of machine learning and Computer Coded Verbal Autopsy (CCVA) algorithms for cause of death determination

    Open AccessMichael Tonderai Mapundu, Chodziwadziwa Kabudula et al.ARTICLEFrontiers in Public Health2022

    Computer Coded Verbal Autopsy (CCVA) algorithms are commonly used to determine the cause of death (CoD) from questionnaire responses extracted from verbal autopsies (VAs). However, they can only operate on structured data and cannot effectively harness information from unstructured VA narratives. Machine Learning (ML) algorithms have also been applied successfully in determining the CoD from VA narratives, allowing the use of auxiliary informatio…

  • Investigating clinic transfers among HIV patients considered lost to follow-up to improve understanding of the HIV care cascade

    Open AccessDavid Etoori, Chodziwadziwa Kabudula et al.ARTICLEPLOS Global Public Health2022

    Investigating clinical transfers of HIV patients is important for accurate estimates of retention and informing interventions to support patients. We investigate transfers for adults reported as lost to follow-up (LTFU) from eight HIV care facilities in the Agincourt health and demographic surveillance system (HDSS), South Africa. Using linked clinic and HDSS records, outcomes of adults more than 90 days late for their last scheduled clinic visit…

  • Long-term household material socioeconomic resources and cognitive health in a population-based cohort of older adults in rural northeast South Africa, 2001–2015

    Open AccessLindsay C Kobayashi, Chodziwadziwa Kabudula et al.ARTICLESSM - Population Health2022

    Material resources owned by households that affect daily living conditions may be salient for cognitive health during aging, especially in low-income settings, but there is scarce evidence on this topic. We investigated relationships between long-term trends in household material resources and cognitive function among older adults in a population-representative study in rural South Africa. Data were from baseline interviews with 4580 adults aged …

  • Twin epidemics

    Open AccessBrian Houle, Chodziwadziwa Kabudula et al.ARTICLEBMC Public Health2022

    Our results indicate that HIV and elevated blood pressure are acting as separate, non-interacting epidemics affecting high proportions of the older adult population. PLWH with unsuppressed viral load were at higher mortality risk compared to those uninfected. Systolic blood pressure was a mortality risk factor independent of HIV status. As antiretroviral therapy becomes more widespread, further longitudinal follow-up is needed to understand how t…
