  • A comparison of verbal autopsy assignment methods to obtain adult cause-specific mortality in two longitudinal studies in Rakai and Kalungu districts of South Central, Uganda

    Open AccessDorean Nabukalu, Tom Lutalo et al.ARTICLEPLOS Global Public Health2026

    Verbal Autopsy (VA) data determines cause of death (CoD) in settings where certification is lacking, using structured interviews on symptoms and circumstances before death. Various methods are used to interpret this information and assign a probable cause of death. Debate exists over replacing physician reviews with automated methods. We compared physician reviews with two computer algorithms in assigning adult CoD. We used adult (≥15 years) VA d…

  • Pathways between intimate partner violence and HIV care and treatment during pregnancy and postpartum

    Open AccessLeah Schrubbe, Catherine Makokha et al.ARTICLEPLOS Global Public Health2025

    Intimate partner violence (IPV) is associated with suboptimal HIV treatment behaviors and health outcomes among perinatal women. Less is known about the postpartum phase or how distinct types of perinatal IPV exposure may inhibit HIV-related care. We conducted a qualitative study nested within an ongoing trial among perinatal women in rural Kenya to explore the influence of IPV on adherence to HIV treatment during pregnancy and postpartum. In 202…

  • Association between breastfeeding duration and educational attainment in rural Southwest Uganda

    Open AccessShamsudeen Mohammed, Clara Calvert et al.ARTICLEGlobal Health Action2024

    BACKGROUND: Breastfeeding is important for early childhood nutrition and health. The positive effects on educational outcomes may be attributed to socioeconomic factors. Socioeconomic status is not a strong predictor of breastfeeding in sub-Saharan African countries. Yet, few studies have investigated the association between breastfeeding and educational outcomes in these countries. OBJECTIVE: This study investigated the association between breas…

  • Estimation of cause-specific mortality in Rakai, Uganda, using verbal autopsy 1999-2019

    Open AccessDorean Nabukalu, Júlia Almeida Calazans et al.ARTICLEGlobal Health Action2024

    BACKGROUND: There are scant data on the causes of adult deaths in sub-Saharan Africa. We estimated the level and trends in adult mortality, overall and by different causes, in rural Rakai, Uganda, by age, sex, and HIV status. OBJECTIVES: To estimate and analyse adult cause-specific mortality trends in Rakai, Uganda. METHODOLOGY: Mortality information by cause, age, sex, and HIV status was recorded in the Rakai Community Cohort study using verbal …

  • Changes in preterm birth and stillbirth during Covid-19 lockdowns in 26 countries

    Open AccessClara Calvert, Meredith Brockway et al.ARTICLENature Human Behaviour2023Cited by: 1References: 59

    Preterm birth (PTB) is the leading cause of infant mortality worldwide. Changes in PTB rates, ranging from −90% to +30%, were reported in many countries following early COVID-19 pandemic response measures ('lockdowns'). It is unclear whether this variation reflects real differences in lockdown impacts, or perhaps differences in stillbirth rates and/or study designs. Here we present interrupted time series and meta-analyses using harmonized data f…

  • Abortion metrics

    Open AccessVéronique Filippi, Mardieh Dennis et al.ARTICLEBMJ Global Health2021

    Consensus is lacking on the most appropriate indicators to document progress in safe abortion at programmatic and country level. We conducted a scoping review to provide an extensive summary of abortion indicators used over 10 years (2008–2018) to inform the debate on how progress in the provision and access to abortion care can be best captured. Documents were identified in PubMed and Popline and supplemented by materials identified on major non…

  • Retracted

    Open AccessDenna Michael, Chifundo Kanjala et al.ARTICLEGlobal Health Action2014

    INTRODUCTION: Spectrum epidemiological models are used by UNAIDS to provide global, regional and national HIV estimates and projections, which are then used for evidence-based health planning for HIV services. However, there are no validations of the Spectrum model against empirical serological and mortality data from populations in sub-Saharan Africa. METHODS: Serologic, demographic and verbal autopsy data have been regularly collected among ove…

  • Using HIV-attributable mortality to assess the impact of antiretroviral therapy on adult mortality in rural Tanzania

    Open AccessChifundo Kanjala, Denna Michael et al.ARTICLEGlobal Health Action2014

    BACKGROUND: The Tanzanian national HIV care and treatment programme has provided free antiretroviral therapy (ART) to HIV-positive persons since 2004. ART has been available to participants of the Kisesa open cohort study since 2005, but data to 2007 showed a slow uptake of ART and a modest impact on mortality. Additional data from the 2010 HIV serological survey provide an opportunity to update the estimated impact of ART in this setting. METHOD…

  • How have ART treatment programmes changed the patterns of excess mortality in people living with HIV? Estimates from four countries in East and Southern Africa

    Open AccessEmma Slaymaker, Jim Todd et al.ARTICLEGlobal Health Action2014

    BACKGROUND: Substantial falls in the mortality of people living with HIV (PLWH) have been observed since the introduction of antiretroviral therapy (ART) in sub-Saharan Africa. However, access and uptake of ART have been variable in many countries. We report the excess deaths observed in PLWH before and after the introduction of ART. We use data from five longitudinal studies in Malawi, South Africa, Tanzania, and Uganda, members of the network f…

  • Measuring causes of adult mortality in rural northern Malawi over a decade of change

    Open AccessJudith R Glynn, Clara Calvert et al.ARTICLEGlobal Health Action2014

    BACKGROUND: Verbal autopsy could be more widely used if interpretation by computer algorithm could be relied on. We assessed how InterVA-4 results compared with clinician review in diagnosing HIV/AIDS-related deaths over the period of antiretroviral (ART) roll-out. DESIGN: In the Karonga Prevention Study demographic surveillance site in northern Malawi, all deaths are followed by verbal autopsy using a semi-structured questionnaire. Cause of deat…

  • InterVA-4 as a public health tool for measuring HIV/Aids mortality

    Open AccessPeter Bya, Clara Calvert et al.ARTICLEGlobal Health Action2013

    BACKGROUND: Reliable population-based data on HIV infection and AIDS mortality in sub-Saharan Africa are scanty, even though that is the region where most of the world's AIDS deaths occur. There is therefore a great need for reliable and valid public health tools for assessing AIDS mortality. OBJECTIVE: The aim of this article is to validate the InterVA-4 verbal autopsy (VA) interpretative model within African populations where HIV sero-status is…
