  • 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…

  • 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…

  • Displacements in reported date of birth and differences in age at death in surveys of child mortality

    Open AccessAndreas Møller Jensen, Sanne Marie Thysen et al.ARTICLEJournal of Population Research2025

    Child mortality data in low- and middle-income countries are often derived from survey data prone to imprecision due to recall. Such imprecisions can affect the accuracy of date of birth (DOB) and age at death (AAD). Bandim Health Project runs two Health and Demographic Surveillance Systems (HDSSs) collecting prospective information on pregnancies, births, and deaths in Guinea-Bissau. In a survey, HDSS resident women were interviewed on their bir…

  • Gender disparities in death registration during the Covid-19 pandemic in an urban African setting

    Open AccessOrsola Torrisi, Amabelia Rodrigues et al.ARTICLEDemographic Research2025Referências: 22

    BACKGROUND In many low- and middle-income countries (LMICs), the completeness of death registration is lower among women, hampering accurate monitoring of health and mortality, gender equality, and rights. OBJECTIVE We quantify the gender gap in death registration and examine its determinants in Guinea-Bissau, a data-scarce West African context during 2020–2023, a period of potentially high mortality. METHODS We collected survey data from 477 urb…

  • 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…

  • Estimer la mortalité aux âges élevés dans les pays à données incomplètes

    Open AccessAshira Menashe‐oren, Ashira Menashe-Oren et al.ARTICLEPopulation2024Citada por: 2Referências: 40

    La mortalité aux âges élevés reste peu documentée dans les pays où les systèmes d'enregistrement et les statistiques de l'état civil sont incomplets. Les enquêtes comportant des questions sur la survie des parents peuvent contribuer à combler cette lacune en fournissant des estimations de la mortalité des plus de 50 ans. Notre article évalue si des biais de sélection pourrait altérer la qualité de ces estimations. Nous analysons les données de tr…

  • 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…

  • Improving old-age mortality estimation with parental survival histories in surveys

    Open AccessBruno Masquelier, Ashira Menashe‐oren et al.ARTICLEDemographic Research2024Citada por: 1Referências: 36

    BACKGROUND: In many low- and middle-income countries, the mortality of adults over 50 years of age is poorly monitored because death registration systems are deficient. Nationally representative surveys currently focus on the survival of children or adults aged 15 to 49 years. OBJECTIVE: We propose to measure adult survival beyond age 50 via parental survival histories, in which survey respondents provide data on their parents’ ages at the time o…

  • Excess mortality associated with HIV

    Open AccessShannon Farley, Shannon M Farley et al.ARTICLEDemographic Research2024Referências: 21

    BACKGROUND: Incomplete vital statistics systems in resource-limited countries hinder accurate HIV epidemic assessments. Population-based survey data combined with HIV infection biomarkers may partially address this gap, providing excess mortality estimates in households where people living with HIV (PLWH) reside. OBJECTIVE: Examine household-level excess HIV mortality in households with PLWH using population-based survey data, including mortality…

  • 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…

  • A Web-Based Tool for Quantification of Potential Gains in Life Expectancy by Preventing Cause-Specific Mortality

    Open AccessAruna Chandran, Churong Xu et al.ARTICLEFrontiers in Public Health2021

    Introduction: Local health departments are currently limited in their ability to use life expectancy (LE) as a benchmark for improving community health. In collaboration with the Baltimore City Health Department, our aim was to develop a web-based tool to estimate the potential lives saved and gains in LE in specific neighborhoods following interventions targeting achievable reductions in preventable deaths. Methods: The PROLONGER (Im PRO ved LON…

  • Errors in reported ages and dates in surveys of adult mortality

    Bruno Masquelier, Mufaro Kanyangarara et al.ARTICLEPopulation Studies2021Citada por: 4Referências: 28

    Sibling survival histories are a major source of adult mortality estimates in countries with incomplete death registration. We evaluate age and date reporting errors in sibling histories collected during a validation study in the Niakhar Health and Demographic Surveillance System (Senegal). Participants were randomly assigned to either the Demographic and Health Survey questionnaire or a questionnaire incorporating an event history calendar, reca…

    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

  • Improving the demand for birth registration

    Open AccessMahari Yihdego, Ayanaw Amogne et al.ARTICLEBMJ Global Health2020

    INTRODUCTION: Birth registration remains limited in most low and middle-income countries. We investigated which characteristics of birth registration facilities might determine caregivers' decisions to register children in Ethiopia. METHODS: We conducted a discrete choice experiment in randomly selected households in Addis Ababa and the Southern Nations, Nationalities, and People's Region. We interviewed caregivers of children 0-5 years old. We a…

  • Biases in Survey Estimates of Neonatal Mortality

    Open AccessHelleringer, Stephane Helleringer et al.ARTICLEDemography2020Citada por: 5Referências: 37

    Neonatal deaths (occurring within 28 days of birth) account for close to one-half of all deaths among children under age 5 worldwide. In most low- and middle-income countries, data on neonatal deaths come primarily from household surveys. We conducted a validation study of survey data on neonatal mortality in Guinea-Bissau (West Africa). We used records from an urban health and demographic surveillance system (HDSS) that monitors child survival p…

  • Tracing Long- and Short-term Migrants for Participation in Demographic and Epidemiological Studies

    Open AccessMufaro Kanyangarara, Laetitia Douillot et al.ARTICLECAM2020Citada por: 1Referências: 31

    Migration of participants in demographic and epidemiological studies results in missing data. One approach to reduce resulting losses in statistical power and potential biases is to follow up migrants at their new residence. We describe the follow-up of migrants who were eligible for participation in a trial of a new questionnaire to measure adult mortality in Niakhar, Senegal. We conducted a short inquiry in the migrant's last known household to…

  • Improving age measurement in low- and middle-income countries through computer vision

    Open AccessHelleringer, Stephane Helleringer et al.ARTICLEDemographic Research2019Citada por: 4Referências: 78

    Age misreporting is pervasive in most low- and middle-income countries (LMIC). It may bias estimates of key demographic indicators, such as those required to track progress towards sustainable development goals. Existing methods to improve age data are oft

  • Estimating mortality from external causes using data from retrospective surveys

    Open AccessGilles Pison, Bruno Masquelier et al.ARTICLEDemographic Research2018Referências: 33

    In low- and middle-income countries (LMICs), data on causes of death is often inaccurate or incomplete. In this paper, we test whether adding a few questions about injuries and accidents to mortality questionnaires used in representative household surveys

  • Spillover effects of HIV testing policies

    Open AccessJemima A Frimpong, Thomas D’Aunno et al.ARTICLEBMC Public Health2016

    Our findings highlight potential positive spillover effects of HIV testing policies on HCV testing practices. They also suggest that maximizing the benefits of HIV policies may require other initiatives, including resources and programmatic efforts that support systematic integration with other services and effective implementation

  • Understanding the Adolescent Gap in HIV Testing Among Clients of Antenatal Care Services in West and Central African Countries

  • Childhood Illness Prevalence and Health Seeking Behavior Patterns in Rural Tanzania

    Open AccessAlmamy Malick Kante, Hialy Gutierrez et al.ARTICLEBMC Public Health2015

    Our results suggest that child age, caregiver education attainment, and household wealth and location may be associated with childhood illness and care seeking behavior patterns. Interventions should be explored that target children and caregivers according to these factors, thereby better addressing barriers and optimizing health outcomes especially for children at risk of dying before the age of five

  • Rewards and challenges of providing HIV testing and counselling services

    Open AccessShannon Bott, Sarah Bott et al.ARTICLEHealth Policy and Planning2015Referências: 40

    The rapid scale-up of human immunodeficiency virus (HIV) testing, counselling and treatment throughout sub-Saharan Africa has raised questions about how to protect patients' rights to consent, confidentiality, counselling and care in resource-constrained settings. The Multi-country African Testing and Counselling for HIV (MATCH) study investigated client and provider experiences with different modes of testing in sub-Saharan Africa. One component…
