    The purpose of this study is to investigate the downstream effects of anti-abortion legislation on the practice of obstetrics and gynecology in urban Texas. We conducted semi-structured interviews until saturation with eleven obstetricians/gynecologists (OBGYNs) to explore the effects of Texas’s abortion laws. Analysis consisted of inductive and deductive approaches. We identified three main themes regarding the downstream effects of Texas aborti…

  • A context-responsive health systems intervention improves the uptake of early infant HIV diagnosis

    Open AccessLeticia Chimwemwe Suwedi-Kapesa, Augustine Choko et al.ARTICLEPLOS Global Public Health2026

    Health system challenges limit uptake of early infant diagnosis of HIV (EID). Context-appropriate strategies are required to achieve global 95% six-week testing target. We evaluated a co-designed context-appropriate enhanced health system (EEHS) intervention to strengthen client identification, appointment booking systems, leadership, and facility-based training to improve enrolment of Infants Exposed to HIV (IEH) in HIV care and testing at six w…

  • Parenting under the triple burden of violence, depression, and poor diet quality

    Open AccessLuissa Vahedi, Ilana Seff et al.ARTICLEPLOS Global Public Health2026

    Parenting while experiencing intimate partner violence (IPV), depression, and poor diet quality can contribute to child health inequities. Syndemic theory offers a framework to understand how maternal conditions can lead to inequitable child health outcomes, such as diarrheal disease: a risk factor for childhood mortality and stunting. This study uses the 2022 Nepal Demographic and Health Survey to test an intergenerational syndemic model address…

  • Prevalence and factors associated with mental health problems among adolescents living with HIV as screened by youth peers in rural Uganda

    Open AccessMary Abwola Olwedo, Simon Eleku et al.ARTICLEPLOS Global Public Health2026

    Adolescents living with HIV face numerous psychosocial challenges that increase their vulnerability to mental health problems. However, limited evidence exists on the prevalence and contributing factors among this population in the Teso region of Uganda. This study assessed the prevalence of mental health problems and associated factors among adolescents living with HIV in the Teso region. A cross-sectional study was conducted among adolescents a…

  • Migration and its impact on universal HIV testing and treatment in the HPTN 071 (PopART) study communities

    Open AccessDavid Macleod, Sian Floyd et al.ARTICLEPLOS Global Public Health2026

    Migrants have been identified as a population left behind by the AIDS (Acquired Immune Deficiency Syndrome) response, with evidence showing poorer HIV (Human Immunodeficiency Virus) outcomes and reduced intervention effectiveness in mobile populations. We used data from the HPTN 071 (PopART) trial (ClinicalTrials.gov number, NCT01900977) to investigate migration and HIV-related indicators, assessing whether community migration influenced PopART t…

  • Prevalence, locations and predictors of attitudes accepting both intimate partner violence and additional forms of violence against women and girls in South Sudan

    Open AccessA I Lamadrid, Ignacio Leiva-Escobar et al.ARTICLEPLOS Global Public Health2025

    Most research on violence against women and girls (VAWG) in South Sudan has focused on intimate partner violence (IPV) neglecting other forms of VAWG. This research aims to determine the prevalence of attitudes accepting IPV and whether it overlaps with attitudes accepting additional forms of VAWG (child marriage, raiding villages for women during cattle rustling or other raids or female genital mutilation) in South Sudanese men and women, or are…

  • Women’s self-help group participation and discussion of reproductive coercion

    Open AccessJasmine Uysal, Nicole E Johns et al.ARTICLEPLOS Global Public Health2025

    Reproductive coercion (RC) and intimate partner violence (IPV) are prevalent in Kenya and undermine women’s reproductive agency; community-based women’s groups may offer an opportunity to address these issues. We quantitatively examined women’s participation in women-only self-help groups, described discussions of RC within these groups, and assessed differences based on prior experiences of RC and IPV among a clinic-based sample of Kenyan women …

  • Assessing the impact of Covid-19 on nurturing care in Nairobi slums

    Open AccessRobert C Hughes, Silas Onyango et al.ARTICLEPLOS Global Public Health2025

    The Covid-19 pandemic and mitigation measures had widespread societal impacts. Young children are particularly vulnerable yet the ways the pandemic affected children in informal settlements (slums) are not well described.

  • Building models, building capacity

    Open AccessMark Sendak, Meg Young et al.ARTICLEPLOS Global Public Health2025

    A growing number of researchers and practitioners are embracing a “participatory turn” in machine learning (ML) to improve model development, prevent harm, and provide communities more influence over systems that impact them. In this paper, we explore the intersection of participatory practices in healthcare and the emerging focus on responsible AI with a focus on human immunodeficiency virus (HIV) care. We review the historical context of partic…

  • Integrated health checks as a person-centred approach to systematic screening of household tuberculosis contacts

    Open AccessClaire Jacqueline Calderwood, Edson Marambire et al.ARTICLEPLOS Global Public Health2025

    Globally, tuberculosis incidence and mortality is driven by syndemic interactions of tuberculosis with other chronic conditions including HIV, diabetes and undernutrition in a deleterious social and structural context, often characterised by poverty. Systematic screening for tuberculosis among household contacts is a core element of the WHO tuberculosis strategy but is hampered in high-tuberculosis incidence settings by health system constraints …

  • “I’ve accepted it because at the end of the day there is nothing, I can do about it”

    Open AccessMpho Silima, Nicola Christofides et al.ARTICLEPLOS Global Public Health2024

    In South Africa, Mental Health (MH), HIV, and Intimate Partner Violence (IPV) form a syndemic, that disproportionately affects women. These challenges are often co-occurring and create complex adversities for women. Recognising these intersections and the broader socio-cultural dynamics at play is crucial to understanding the layered experiences of these women and developing effective interventions. This research explores the experiences of the w…

    Open AccessTara Tancred, Vincent Mubangizi et al.ARTICLEPLOS Global Public Health2024

    Anaemia is one of the most common conditions in low- and middle-income countries, with prevalence increasing during pregnancy. The highest burden is in Sub-Saharan Africa and South Asia, where the prevalence of anaemia in pregnancy is 41.7% and 40%, respectively. Anaemia in pregnancy can lead to complications such as prematurity, low birthweight, spontaneous abortion, and foetal death, as well as increasing the likelihood and severity of postpart…

    Open AccessDoreen Tuhebwe, Christine Adyedo et al.ARTICLEPLOS Global Public Health2024

    In Uganda, cervical cancer due to Human Papilloma Virus (HPV) is the most prevalent cancer among women. In 2015, the HPV vaccine was introduced into Uganda’s EPI program, targeting young girls in-and out-of-school. However, HPV vaccine uptake remains low at 44% for the second dose with disparities in vulnerable populations in urban poor settings. We piloted a peer-to-peer education approach in the urban slums of Kisenyi in Kampala, Uganda to addr…

  • The epidemiology of HIV infection among female sex workers in Nairobi, Kenya

    Open AccessTara Beattie, Wendy Adhiambo et al.ARTICLEPLOS Global Public Health2024
