  • Collecting data on HIV/Aids mortality during household surveys

    Open AccessAlbert Dube, Abena Amoah et al.ARTICLEDemographic Research2026

    BACKGROUNDIn countries with limited civil registration, household surveys do not include questions on HIV-related mortality. OBJECTIVEWe aim to test whether accurate data on the HIV status of the deceased siblings of survey respondents could be collected during household surveys conducted in low-and middleincome countries. METHODSWe added HIV questions to the standard module on adult and maternal mortality used in household surveys.We compared th…

  • All-cause and cause-specific mortality trends among people with and without HIV in the Siaya health and demographic surveillance system, Kenya, 2011–2018

    Open AccessJulie Ambia, Adam Trickey et al.ARTICLEGlobal Health Action2026

    BACKGROUND: All-cause mortality among people with HIV (PWH) in sub-Saharan Africa declined after antiretroviral therapy's introduction, but data in rural settings on evolving causes of death as this population age remain limited. OBJECTIVES: To compare all-cause and cause-specific mortality trends among PWH and people without HIV (PWOH) in western Kenya using a prospective cohort study. METHODS: Data from the Siaya Health and Demographic Surveill…

  • Estimates of Under-Five Mortality From a Mobile Phone Survey During the Covid-19 Outbreak

    Open AccessJulio Romero-Prieto, Julio E Romero-Prieto et al.ARTICLEDemography2026

    Under-five mortality estimates for low- and middle-income countries are primarily derived from detailed birth or pregnancy histories collected through in-person household surveys. Such surveys are, however, resource intensive and vulnerable to interruption during epidemic outbreaks and other crises. Remotely deployed mobile phone surveys can circumvent these disadvantages, but their suitability for measuring population-level mortality has not bee…

  • Measuring adult mortality from mobile phone surveys in Burkina Faso, Malawi and the Democratic Republic of the Congo

    Open AccessKassoum Dianou, Bruno Masquelier et al.ARTICLEBMJ Global Health2025

    In many low and middle-income countries, adult mortality estimates are derived from surveys and censuses conducted through face-to-face interviews. These interviews can be time-intensive and are often impractical during health crises or humanitarian emergencies. The expansion in cellphone ownership and network coverage has created new opportunities for collecting demographic data through mobile phone surveys, but our understanding of selection bi…

  • 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…

  • The use of mobile phone surveys for rapid mortality monitoring

    Open AccessDianou Kassoum, Abdramane Soura et al.ARTICLEDemographic Research2025Referências: 47

    BACKGROUND: In low- and middle-income countries, death registration remains low, and mortality estimation is heavily based on surveys and censuses conducted through face-to-face interviews. These operations are costly and time-consuming, and are difficult to conduct during health and security crises. Taking advantage of the rapid increase in cell phone network coverage, mobile phone surveys (MPS) have recently started to be used to collect mortal…

  • Moving towards a person-centred HIV care cascade

    Open AccessDavid Etoori, Alison Wringe et al.ARTICLEPLOS Global Public Health2024

    In 2022, in recognition of lags in data infrastructure, the World Health Organisation (WHO) recommended the use of routinely linked individual patient data to monitor HIV programmes. The WHO also recommended a move to person-centred care to better reflect the experiences of people living with HIV. The switch from aggregated service level data to person-centred data will likely introduce some biases and errors. However, little is understood about …

  • Controlling the first wave of the Covid–19 pandemic in Malawi

    Open AccessJethro Banda, Albert Dube et al.ARTICLEPLOS Global Public Health2024

    We investigated behavioral responses to COVID–19 in Malawi, where a first wave of the pandemic occurred between June and August 2020. Contrary to many countries on the African continent, the Government of Malawi did not impose a lockdown or a stay-at-home order in response to the initial spread of SARS-CoV-2. We hypothesized that, in the absence of such requirements to restrict social interactions, individuals would primarily seek to reduce the r…

  • Interrogating the quality and completion of mortality mobile phone interviews conducted in Malawi during Covid-19

    Open AccessEmmanuel Souza, Emmanuel F Souza et al.ARTICLEDemographic Research2024Referências: 12

    BACKGROUNDMobile phone surveys (MPSs) have gained traction as a tool for gathering survey data, especially following the emergency of COVID-19.However, our understanding of MPS data quality in contexts with limited mobile phone penetration is still modest. OBJECTIVEThis study evaluates (1) the circumstances under which mobile phone survey interviews were conducted and how these might influence the completion and quality of interviews, and (2) whe…

  • Sample selection bias in adult mortality estimates from mobile phone surveys

    Open AccessSahar Ahmed, Julio Romero-Prieto et al.ARTICLEDemographic Research2024Referências: 13

    BACKGROUNDMobile phone surveys are gaining traction in low-and middle-income countries, but mobile phone ownership (MPO) is not universal, potentially introducing sample selection bias in ensuing estimates. OBJECTIVETo evaluate MPO-associated sample selection bias in adult mortality estimates from sibling survival histories (SSH) administered to women of reproductive age. METHODSUsing data from 25 Demographic and Health Surveys, we (1) used logis…

  • Revisiting the Recommended Duration of Interviews Conducted by Mobile Phone in Low- and Middle-income Countries

    Open AccessOrsola Torrisi, Jethro Banda et al.ARTICLECAM2024Referências: 42

    Guidelines for conducting surveys by mobile phone calls in low- and middle-income countries suggest keeping interviews short (<20 minutes). The evidence supporting this recommendation is scant, even though limiting interview duration might reduce the amount of data generated by such surveys. We recruited nearly 2,500 mobile phone users in Malawi and randomly allocated them to 10-, 20-, or 30-minute phone interviews, all ending with questions on p…

  • Increased Age Heaping in Mobile Phone Surveys Conducted in Low-Income and Middle-Income Countries

    Open AccessHelleringer, Samantha W Lau et al.ARTICLESocius Sociological Research for…2023Citada por: 3Referências: 6

    Since the beginning of the coronavirus disease 2019 pandemic, the number of surveys conducted remotely by mobile phone in low-income and middle-income countries has increased rapidly. This shift has helped sustain data collection despite restrictions on mobility and interactions. It might also allow collecting data more frequently on important demographic and socioeconomic topics. However, conducting interviews by mobile phone might affect the ac…

  • Collecting mortality data via mobile phone surveys

    Open AccessMichael Chasukwa, Augustine Choko et al.ARTICLEPLOS Global Public Health2022

    Despite the urgent need for timely mortality data in low-income and lower-middle-income countries, mobile phone surveys rarely include questions about recent deaths. Such questions might a) be too sensitive, b) take too long to ask and/or c) generate unreliable data. We assessed the feasibility of mortality data collection using mobile phone surveys in Malawi. We conducted a non-inferiority trial among a random sample of mobile phone users. Parti…

  • 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…

  • Patterns of engagement in HIV care during pregnancy and breastfeeding

    Open AccessDavid Etoori, Brian Rice et al.ARTICLEBMC Public Health2021

    Almost half of all pregnant women did not have optimal ART coverage during the MTCT risk period. Programmes need to focus on improving retention, and leveraging new pregnancies to re-engage HIV-positive women on ART

    Open AccessJethro Banda, Albert Dube et al.ARTICLEDemographic Research2021Citada por: 1Referências: 23

    Behavioral changes are needed to limit the spread and mitigate the impact of the COVID-19 pandemic

  • Age patterns of under-5 mortality in sub-Saharan Africa during 1990-2018

    Open AccessHallie Eilerts, Hallie Eilerts-Spinelli et al.ARTICLEDemographic Research2021Citada por: 2Referências: 18

    BACKGROUND: Estimates of under-5 mortality (U5M) for sub-Saharan African populations often rely heavily on full birth histories (FBHs) collected in surveys and model age patterns of mortality calibrated against vital statistics from other populations. Health and Demographic Surveillance Systems (HDSSs) are alternate sources of population-based data in much of sub-Saharan Africa, which are less formally utilized in estimation. OBJECTIVE: In this s…

  • Misreporting of Patient Outcomes in the South African National HIV Treatment Database

    Open AccessDavid Etoori, Alison Wringe et al.ARTICLEFrontiers in Public Health2020

    Background: Monitoring progress toward global treatment targets using HIV programme data in sub-Saharan Africa has proved challenging. Constraints in routine data collection and reporting can lead to biased estimates of treatment outcomes. In 2010, South Africa introduced an electronic patient monitoring system for HIV patient visits, TIER.Net. We compare treatment status and outcomes recorded in TIER.Net to outcomes ascertained through detailed …

  • The impact of HIV status on the distance traveled to health facilities and adherence to care. A record-linkage study from rural South Africa

    Open AccessPaul Mee, Brian Rice et al.ARTICLEJournal of Global Health2020

    BACKGROUND: For people living with HIV (PLWH), the burden of travelling to a clinic outside of one's home community in order to reduce the level of stigma experienced, may impact adherence to treatment and accelerate disease progression. METHODS: This study is set in the Agincourt Health and Demographic Surveillance System (HDSS) in South Africa. Probabilistic and interactive methods were used to individually link HDSS data with medical records. …

  • Challenges with tracing patients on antiretroviral therapy who are late for clinic appointments in rural South Africa and recommendations for future practice

    Open AccessDavid Etoori, Alison Wringe et al.ARTICLEGlobal Health Action2020

    Background: It is common practice for HIV programmes to routinely trace patients who are late for a scheduled clinic visit to ensure continued care engagement. In South Africa, patients who are late for a scheduled visit are identified from clinic registers, and called by telephone up to three times by designated clinic staff, with home visits conducted for those who are unreachable by phone. It is important to understand outcomes among late pati…

  • If the results are negative, they motivate us’. Experiences of early infant diagnosis of HIV and engagement in Option B

    Open AccessDavid Etoori, Jenny Renju et al.ARTICLEGlobal Public Health2020

    Few studies have explored the relationship between early infant diagnosis (EID) of HIV and mothers' engagement in care under Option B+. We conducted in-depth interviews with 20 women who initiated antiretroviral therapy (ART) under Option B+ in rural South Africa to explore the interactions between EID and maternal care engagement. Drawing on practice theory, we identified themes relating to Option B+ care engagement and EID. Women's practice of …

  • Population-level adult mortality following the expansion of antiretroviral therapy in Rakai, Uganda

    Open AccessDorean Nabukalu, Georges Reniers et al.ARTICLEPopulation Studies2020Referências: 30

    There are limited data on the impact of antiretroviral therapy (ART) on population-level adult mortality in sub-Saharan Africa. We analysed data for 2000-14 from the Rakai Community Cohort Study (RCCS) in Uganda, where free ART was scaled up after 2004. Using non-parametric and parametric (Weibull) survival analysis, we estimated trends in average person-years lived between exact ages 15 and 50, per capita life-years lost to HIV, and the mortalit…

  • Non-disclosure of HIV testing history in population-based surveys

    Open AccessChristopher T Rentsch, Georges Reniers et al.ARTICLEGlobal Health Action2018

    Background: HIV/AIDS programmes and organisations around the world use routinely updated estimates of the UNAIDS 90-90-90 targets to track progress and prioritise further programme implementation. Any bias in these estimates has the potential to mislead organisations on where gaps exist in HIV testing and treatment programmes. Objective: To measure the extent of undisclosed HIV testing history and its impact on estimating the proportion of people…

  • Identifying gaps in HIV policy and practice along the HIV care continuum

    Open AccessCaoimhe Cawley, Ellen McRobie et al.ARTICLEHealth Policy and Planning2017

    The last decade has seen rapid evolution in guidance from the WHO concerning the provision of HIV services along the diagnosis-to-treatment continuum, but the extent to which these recommendations are adopted as national policies in Kenya, and subsequently implemented in health facilities, is not well understood. Identifying gaps in policy coverage and implementation is important for highlighting areas for improving service delivery, leading to b…
