  • Characteristics of new and re-initiating antiretroviral therapy clients in Malawi

    Open AccessMarguerite Thorp, Kelvin Balakasi et al.ARTICLEGlobal Health Action2026

    New antiretroviral treatment (ART) initiates and re-initiators (returning after interruption in treatment [IIT], defined as ≥28 days late for refill) are at higher risk of future IIT compared to stable clients. Counseling is a core strategy to increase retention among new initiates, but little is known about whether re-initiators may have different counseling needs. We compared sociodemographic and psychosocial characteristics of new initiates an…

  • 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…

  • Motivations for testing and linkage to HIV services following HIV self-testing among fishermen in Kenya

    Open AccessHolly Nishimura, Kawango Agot et al.ARTICLEAIDS Care2026

    HIV self-testing (HIVST) is a promising strategy to expand testing access for hard-to-reach populations such as Kenyan fishermen. We examined motivations and barriers to HIVST use and linkage to HIV prevention and treatment services (including PrEP or ART), within a social network-based intervention (NCT04772469). We conducted interviews (N = 64) and focus group discussions (N = 4) with fishermen in Siaya County, including 30 “promoters” who dist…

  • 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…

  • Stakeholder priorities for ART initiation and early retention strategies in Malawi

    Open AccessSanthi Hariprasad, Khumbo Phiri et al.ARTICLEBMC Public Health2025

    New or returning antiretroviral therapy (ART) clients are largely ineligible for differentiated service delivery (DSD) models. These clients are at increased risk of treatment interruption and may benefit from flexible care models, but stakeholder buy-in may limit progress on interventions for this population. We qualitatively explored stakeholder perceptions and decision-making criteria for scaling DSD models for new or returning ART clients in …

  • 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

  • Men’s Satisfaction with General Health Services is Associated with Future Use of HIV Testing in Malawi

    Open AccessMarguerite Thorp, Kelvin Balakasi et al.ARTICLEAIDS and Behavior2024

    Across sub-Saharan Africa, men are less likely to know their HIV status than women, leading to later treatment initiation. Little is known about how experiences with general health services affect men's use of HIV testing. We used data from a 2019 community-representative survey of men in Malawi to understand frequency and cause of men's negative health service experiences (defined as men reporting they "would not recommend" a facility) and their…

  • Factors associated with men’s health facility attendance as clients and caregivers in Malawi

    Open AccessMarguerite Thorp, Kelvin Balakasi et al.ARTICLEBMC Public Health2022

    Quality of services offered at local health facilities and men's health status were the only variables associated with client facility visits among men, while harmful gender norms, not being married, and being younger were negatively associated with caregiver visits

  • Understanding the Unique Barriers and Facilitators that Affect Men’s Initiation and Retention in HIV Care

    Open AccessKate Coursey, Khumbo Phiri et al.ARTICLEAIDS and Behavior2022

    Men in sub-Saharan Africa are underrepresented in antiretroviral therapy (ART) programs. Our secondary analysis of 40 in-depth interviews with Malawian men living with HIV examined barriers and facilitators for ART initiation versus retention. Interviewees included men who never initiated or initiated ART late (initiation respondents, n = 19); and men who initiated ART but were late for an appointment (retention respondents, n = 21). Transcribed …
