  • HIVST in the presence of a partner among fishermen in Western Kenya

    Open AccessPeter Abade, Phoebe Olugo et al.ARTICLEAfrican Journal of AIDS Research2026

    BACKGROUND: HIV self-testing (HIVST) enables individuals to test privately and can serve as an important tool to mitigate stigma and fear of HIV testing and unintended disclosure, especially among men, who have lower voluntary testing rates than women. AIM: Within an intervention study involving distribution of HIVST kits by fishermen to their peers [NCT04772469], we explore the experiences and the motivations of men who chose to self-test for HI…

  • Exploring patients’ and healthcare providers’ knowledge and perceptions of benefits, challenges, and resource requirements in integrating telemedicine services into routine HIV care in western Kenya

    Zachary A Kwena, Francesca Odhiambo et al.ARTICLEAIDS Care2026

    Telemedicine offers a patient-centered approach to chronic care, including HIV. However, its uptake depends on the users' perceptions of its benefits and challenges. We explored patients' and providers' knowledge, perceptions, benefits, challenges, and resource needs for integrating telemedicine into routine HIV care. We conducted a qualitative study involving eight gender-stratified focus group discussions and 23 key informant interviews with pe…

  • Hazardous alcohol use is associated with sexual behaviors that increase risk for HIV acquisition among fishermen in a high HIV prevalence area of Kenya

    Open AccessSarah A Gutin, Holly Nishimura et al.ARTICLEAIDS Care2026

    Links between hazardous alcohol use and HIV acquisition are well documented, with less known about this relationship among fishermen, a priority group for HIV prevention. We examined associations between hazardous alcohol use and sexual risk behaviors among fishermen in Kenya using 2022 data from 733 fishermen in three Lake Victoria communities. Measures included the AUDIT-C and sexual relationship histories. Logistic regression models assessed a…

  • Household healthcare seeking patterns for emergent ill-health in Migori, Western Kenya

    Open AccessZachary A Kwena, Zachary Kwena et al.ARTICLEFrontiers in Public Health2025

    Background Healthcare-seeking decisions reflect personal assessments of illness etiology and severity to determine whether, how, and where to seek care. Understanding these contexts enables targeted interventions to address barriers and ensure timely access to quality services. We examined patterns of household healthcare seeking for emergent ill-health in Western Kenya. Methods As part of a multi-site mixed-methods study evaluating a patient-cen…

  • Misconceptions and limited experience with HIV pre-exposure prophylaxis (PrEP) among fishermen in Western Kenya

    Open AccessPhoebe Olugo, Holly Nishimura et al.ARTICLEAIDS Care2025

    Daily oral HIV pre-exposure prophylaxis (PrEP) is highly effective when taken consistently, but its uptake remains low among mobile fishermen in Kenya. This study explored barriers and facilitators to PrEP uptake in three Lake Victoria beach communities. In-depth interviews (IDIs) and focus group discussions (FGDs) were conducted with 65 fishermen, purposively sampled by community, age and study arm. IDIs and FGDs examined PrEP knowledge, percept…

  • There is no need to leave the beach to test”

    Open AccessJayne Lewis-Kulzer, Phoebe Olugo et al.ARTICLEBMC Public Health2025

    While few fishermen had ever used HIVST, this study found high awareness, positive perceptions, and substantial willingness to use and distribute HIVST to other men. The "promoter" model, with known peers engaged in disseminating HIVST information and test kits, shows promise for engaging men in testing

  • Gaps in Effective HIV Pre-exposure Prophylaxis Screening and Uptake Among Fishermen in Kenya

    Open AccessLila A Sheira, Benard Ayieko et al.ARTICLEAIDS and Behavior2025

    Despite oral daily HIV pre-exposure prophylaxis (PrEP) effectiveness, uptake remains a challenge. Awareness of one's HIV status and engagement in prevention is essential to interrupting transmission among populations at high risk of HIV. We explored gaps in HIV risk perception, screening, and PrEP uptake among high HIV-risk fishermen living and working along Lake Victoria, Kenya. Data are from the Owete study (NCT04772469), which evaluated the im…

  • Clinic presentation delay and tuberculosis treatment outcomes in the Lake Victoria region of East Africa

    Open AccessGrace E Mulholland, Michael E Herce et al.ARTICLEPLOS Global Public Health2023

    In the Lake Victoria region of East Africa, little is known about delays between tuberculosis (TB) symptom onset and presentation at a clinic. Associations between clinic presentation delay and TB treatment outcomes are also poorly understood. In 2019, we abstracted data from routine TB treatment records for all adults (n = 776) initiating TB treatment in a 6-month period across 12 health facilities near Lake Victoria. We interviewed 301 cohort m…

  • Geographic mobility and treatment outcomes among people in care for tuberculosis in the Lake Victoria region of East Africa

    Open AccessGrace E Mulholland, Michael E Herce et al.ARTICLEPLOS Global Public Health2023

    Geographic mobility may disrupt continuity of care and contribute to poor clinical outcomes among people receiving treatment for tuberculosis (TB). This may occur especially where health services are not well coordinated across international borders, particularly in lower and middle income country settings. In this work, we describe mobility and the relationship between mobility and unfavorable TB treatment outcomes (i.e., death, loss to follow-u…

  • Acceptability and Feasibility of Pharmacy-Based Delivery of Pre-Exposure Prophylaxis in Kenya

    Open AccessStephanie Roche, Njeri Wairimu et al.ARTICLEAIDS and Behavior2021

    As countries scale up pre-exposure prophylaxis (PrEP) for HIV prevention, diverse PrEP delivery models are needed to expand access to populations at HIV risk that are unwilling or unable to access clinic-based PrEP care. To identify factors that may influence implementation of retail pharmacy-based PrEP delivery in Kenya, we conducted in-depth interviews with 40 pharmacy clients, 16 pharmacy providers, 16 PrEP clients, and 10 PrEP providers from …

  • Effects of a Home-Based Intervention on HIV Prevention Health Behaviors in Pregnant/Postpartum Kenyan Women

    Open AccessJami L Anderson, Peng Li et al.ARTICLEAIDS and Behavior2020

  • Educating men about vaginal microbicides

    Serah Gitome, Serah W Gitome et al.ARTICLECulture Health & Sexuality2020

    Men desire to be involved in their partner's decision-making about vaginal microbicide use. This coincides with women's desire to inform male partners about their microbicide use. Educating men about microbicides may enhance acceptability and generate critical support for the female participants of microbicide trials. In this multiphase mixed-methods study, we adapted an educational intervention on vaginal microbicides and tested it among men (n …
