  • Multilevel factors influencing HIV care and management in the Deep South

    Open AccessIrvin Ong, Maeve Brin et al.ARTICLEAIDS Care2026

    The United States Deep South bears a disproportionate HIV burden, with low rates of retention in care and viral suppression among people living with HIV (PWH). Factors influencing HIV care engagement can be understood through the modified social ecological model (MSEM), which comprises five interconnected layers: individual, network, community, policy, and HIV epidemic stage. We interviewed thirty HIV care professionals from Alabama, Mississippi,…

  • An Evidence-Based Approach to Facilitating PrEP Initiation Among YMSM

    Rebecca Schnall, Shivani Kaw et al.ARTICLEAIDS Education2026

    Men who have sex with men (MSM) account for nearly 70% of new HIV infections annually. Although awareness of pre-exposure prophylaxis (PrEP) is growing, uptake remains low among young MSM. Peer navigators are well positioned to guide patients through PrEP care, provide psychosocial support, build trust, and demystify PrEP. Given strong evidence to support mobile health (mHealth) apps for enhancing HIV prevention knowledge, our team created MyPEEP…

  • Awareness and use of pre-exposure prophylaxis in a United States national sample of young sexual and gender minority men

    Sophia McInerney, Patrick Veihman et al.ARTICLEAIDS Care2026

    Young sexual and gender minority (SGM) men remain disproportionately affected by the HIV epidemic. Although pre-exposure prophylaxis (PrEP) is highly effective in preventing HIV acquisition, uptake among SGM men in the United States (US) remains suboptimal. To better understand disparities in PrEP awareness, use, and adherence, we examined baseline survey data from the Limited Interaction Targeted Epidemiology (LITE-2) cohort, which included 3,14…

  • Pre-Exposure prophylaxis knowledge, use and adherence among a US national sample of women

    Samira Gure, Jean Jimenez et al.ARTICLEAIDS Care2026

    Pre-exposure prophylaxis (PrEP) is a proven strategy for HIV prevention, yet uptake among women vulnerable to HIV remains low. This study draws on survey data and urine-based adherence testing from the American Women Assessing Risk Epidemiologically (AWARE) study to assess PrEP knowledge, use, and adherence in a behaviorally vulnerable sample. Despite high awareness of PrEP, actual use and willingness to consider PrEP were minimal. Objective adhe…

  • The Dual Burden of Weight in YMSM

    Open AccessChing‐Yu Wang, Dustin T Duncan et al.ARTICLEJournal of Racial and Ethnic…2026

    BACKGROUND/OBJECTIVES: Young men who have sex with men (YMSM) navigate a unique intersection of health risks characterized by structural drivers of obesity and intense sociocultural pressures for thinness. While Body Mass Index (BMI) differences are documented in the general population, less is known about how these patterns manifest within the specific appearance-potent subcultures of YMSM. This study describes BMI profiles across racial/ethnic …

This study investigates the roles of social support and substance use as mediators in the relationship between mental health and antiretroviral therapy (ART) adherence among PLHIV in a multisite, international context. Cross-sectional data fr…

  • Detailed HIV Self-Testing Patterns Derived from Paradata in the mLab App Clinical Trial

    Open AccessThomas F Scherr, Thomas Scherr et al.ARTICLEAIDS and Behavior2026

    Self-testing is a critical component of public health initiatives aimed at slowing and stopping the spread of HIV. It has the promise of accessibility, reliability, and convenience, and because of the benefits derived from its inherent privacy, self-testing may overcome the barriers associated with HIV screening with at-risk populations. Still, questions remain about whether and how self-testing can adequately link patients to care and engage the…

  • Understanding Patient Barriers and Facilitators Throughout the PrEP Care Continuum

    Open AccessTrinity Casimir, Maeve Brin et al.ARTICLEAIDS and Behavior2026

    Pre-exposure prophylaxis (PrEP) is a medication that significantly reduces the risk of HIV infection when taken as prescribed, however, less than 36% of the 1.2 million eligible-for-PrEP Americans are currently prescribed it. PrEP navigators can help reduce barriers to PrEP uptake and increase access to care for those vulnerable to HIV. As part of formative work for designing an e-peer navigation tool, MyPEEPS Mobile Plus, twenty PrEP navigators …

  • An Evaluation of Social Media and Geospatial Dating Apps for Recruitment of a National Sample of Young Men Who Have Sex with Men in the Lite-2 Study

    Open AccessIsabella Bonnewit, Rebecca Schnall et al.ARTICLEAIDS and Behavior2026

    In 2022, over two thirds of individuals diagnosed with HIV in the United States were people of color, half resided in the south, and 67% of new cases were attributed to male-to male sexual transmission (Centers For Disease Control, 2024). To combat these health disparities, the Ending the HIV Epidemic (EHE) initiative recommends that HIV prevention research focus on targeted populations and geographic regions with high rates of new HIV diagnosis.…
