  • The implementation of tuberculosis preventive therapy in HIV care clinics in Africa, Asia and Latin America

    Open AccessRemo Schmutz, Nicolas Banholzer et al.ARTICLEBMJ Global Health2026

    INTRODUCTION: Towards the 'End TB Strategy' targets, the WHO recommends the provision of tuberculosis (TB) preventive therapy (TPT) for high-risk groups including people living with HIV (PLWH). 3 years after the release of the updated 2020 WHO guidelines, we investigated the implementation of TPT services at HIV clinics in low-income and middle-income countries (LMICs), focusing on TB screening, populations eligible for TPT and available TPT regi…

  • Record linkage without patient identifiers

    Open AccessKhumbo Shumba, Joep Bor et al.ARTICLEPLOS Global Public Health2025

    Linkage between health databases typically requires patient identifiers such as names and personal identification numbers. We developed and validated a record linkage strategy to combine administrative health databases without identifiers for South Africa’s public sector HIV program. We linked CD4 counts and HIV viral loads from South Africa’s TIER.Net with the National Health Laboratory Service (NHLS) database for patients receiving care between…

  • Within-country heterogeneity in patterns of social contact relevant for tuberculosis infection transmission, prevention, and care

    Open AccessKate E Legrand, Anita Edwards et al.ARTICLEPLOS Global Public Health2025

    Mycobacterium tuberculosis ( Mtb ) transmission is driven by variable social, environmental, and biological factors, including the number and duration of indoor contacts. Social contact data can provide information on potential transmission patterns, but is underutilised outside the field of mathematical modelling. We explore three contexts where contact data can provide valuable insights: 1) household contact tracing; 2) infection prevention and…

  • Pregnancy reporting and biases in under-five mortality in three African HDSSs

    Open AccessHallie Eilerts-Spinelli, Julio E Romero-Prieto et al.ARTICLEPopulation Studies2025Referências: 48

    In the absence of complete civil registration and vital statistics, Health and Demographic Surveillance Systems (HDSSs) are important sources of population-based data throughout sub-Saharan Africa. However, HDSS data on the vital status of newborns are often unreliable due to omission of those who were born and died between two rounds of data collection and are therefore never enumerated. This study investigates whether pregnancy registration imp…

  • Worldwide trends in underweight and obesity from 1990 to 2022

    Open AccessNowell H Phelps, Rosie Singleton et al.ARTICLEThe Lancet2024

    BACKGROUND: Underweight and obesity are associated with adverse health outcomes throughout the life course. We estimated the individual and combined prevalence of underweight or thinness and obesity, and their changes, from 1990 to 2022 for adults and school-aged children and adolescents in 200 countries and territories. METHODS: ). For school-aged children and adolescents, we report thinness (BMI 2 SD above the median). FINDINGS: From 1990 to 20…

  • 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…

  • Increasing HIV testing and linkage to care among men in rural South Africa using conditional financial incentives and a decision support app

    Open AccessThulile Mathenjwa, Luchuo Engelbert Bain et al.ARTICLEPLOS Global Public Health2024

    Men in sub-Saharan Africa are less likely to accept HIV testing and link to HIV care than women. We conducted a trial to investigate the impact of conditional financial incentives and a decision support application, called EPIC-HIV, on HIV testing and linkage to care. We report the findings of the trial process evaluation to explore whether the interventions were delivered as intended, identify mechanisms of impact and any contextual factors that…

  • Effect of a Male-Targeted Digital Decision Support Application Aimed at Increasing Linkage to HIV Care Among Men

  • Covid-19 vaccine uptake, confidence and hesitancy in rural KwaZulu-Natal, South Africa between April 2021 and April 2022

    Open AccessRachael Piltch-Loeb, Lusanda Mazibuko et al.ARTICLEPLOS Global Public Health2023

    High COVID-19 vaccine hesitancy in South Africa limits protection against future epidemic waves. We evaluated how vaccine hesitancy and its correlates evolved April 2021-April 2022 in a well-characterized rural KwaZulu-Natal setting. All residents aged >15 in the Africa Health Research Institute’s surveillance area were invited to complete a home-based, in-person interview. We described vaccine uptake and hesitancy trends, then evaluated associat…

  • Linkage to HIV care and hypertension and diabetes control in rural South Africa

    Open AccessItai M Magodoro, Stephen Olivier et al.ARTICLEPLOS Global Public Health2022

    Non-communicable diseases (NCDs) account for half of all deaths in South Africa, partly reflecting unmet NCDs healthcare needs. Leveraging existing HIV infrastructure is touted as a strategy to alleviate this chronic care gap. We evaluated whether HIV care platforms are associated with improved NCDs care. We conducted a community-based screening of adults in rural KwaZulu-Natal, collecting BP, HbA1c, and health services utilization data. Care cas…

  • Worldwide trends in hypertension prevalence and progress in treatment and control from 1990 to 2019

    Open AccessBin Zhou, Rodrigo M Carrillo-Larco et al.ARTICLEThe Lancet2021

    BACKGROUND: Hypertension can be detected at the primary health-care level and low-cost treatments can effectively control hypertension. We aimed to measure the prevalence of hypertension and progress in its detection, treatment, and control from 1990 to 2019 for 200 countries and territories. METHODS: We used data from 1990 to 2019 on people aged 30-79 years from population-representative studies with measurement of blood pressure and data on blo…

  • Height and body-mass index trajectories of school-aged children and adolescents from 1985 to 2019 in 200 countries and territories

    Open AccessAndrea Rodriguez-Martinez, Andrea Rodriguez‐Martinez et al.ARTICLEThe Lancet2020

    BACKGROUND: Comparable global data on health and nutrition of school-aged children and adolescents are scarce. We aimed to estimate age trajectories and time trends in mean height and mean body-mass index (BMI), which measures weight gain beyond what is expected from height gain, for school-aged children and adolescents. METHODS: For this pooled analysis, we used a database of cardiometabolic risk factors collated by the Non-Communicable Disease …

    Anita Edwards, Mark J Siedner et al.ARTICLEAfrican Journal of AIDS Research2020

    Objective : We compared the prevalence of frailty by HIV serostatus and related biomarkers to the modified frailty phenotype among older individuals in a rural population in South Africa. Methods : Questionnaire data were from a cohort of people living with HIV (PWH) on antiretroviral therapy (ART) and HIV-uninfected people aged 50 years and older sampled from the Africa Health Research Institute Demographic Health and Surveillance area in northe…

  • Rising rural body-mass index is the main driver of the global obesity epidemic in adults

    Open AccessNCD Risk Factor Collaboration, Honor Bixby et al.ARTICLENature2019

    Body-mass index (BMI) has increased steadily in most countries in parallel with a rise in the proportion of the population who live in cities 1,2 . This has led to a widely reported view that urbanization is one of the most important drivers of the global rise in obesity 3–6 . Here we use 2,009 population-based studies, with measurements of height and weight in more than 112 million adults, to report national, regional and global trends in mean B…
