This study aimed to (1) identify latent classes of stigma and discrimination experiences among men who have sex with men (MSM) living with HIV; (2) examine the associations between class membership and mental health outcomes, and (3) investigate the moderating effects of social support and resilience. The study used the baseline (N = 224) and six-month follow-up data (N = 118) from a longitudinal cohort study on HIV and hypertension among African American and Asian Pacific American MSM in Hawai'i and Philadelphia from 2019 to 2023. Latent class analysis was conducted to characterize the patterns of stigma and discrimination experience. Multivariable regression was conducted to examine the association between class membership and mental health outcomes. Interaction terms were added to examine the moderation effects of social support and resilience on the association between class memberships and mental health outcomes. A five-class model was identified: Class (1) high on internalized homophobia and low on all discrimination experiences; Class (2) high on racial discrimination; Class (3) high on sexual identity discrimination; Class (4) low on internalized homophobia and all discrimination experiences; Class (5) high on physical disability discrimination and internalized homophobia. Class 5 consistently predicted worse mental health outcomes, compared to Class 4. The association between Class 2 (high racial discrimination) and depression was moderated by perceived social support. The study reveals complex experiences of intersectional stigma and discrimination among MSM living with HIV, highlighting the need for further research on the intersecting effects of multiple disadvantages among aging sexual minorities.

Pregnant patients living with HIV are a priority group for the recruitment into the HIV healthcare cascade to prevent adverse maternal and neonatal health outcomes. Understanding the structural, interpersonal, and individual factors that are associated with detectable HIV viremia is of importance to guide outreach and intervention priorities. This was a retrospective cohort study of pregnant patients living with HIV who delivered from January 1, 2017, to December 31, 2023, at a tertiary-level hospital and referral institution for HIV care in Porto Alegre, Brazil. The socio-ecological model was used to guide hypothesis testing regarding associations with detectable viremia. In total, 549 patients were included, of whom 110 (20%) were found to have detectable viremia. Significant differences between detectable and undetectable viremia included prenatal care, homelessness, having a sero-different partner, and stimulant use. Multivariable associations included prenatal care (adjusted Risk Ratio [aRR] = 0.20, 95% Confidence Interval [95% CI] = 0.15-0.26), homelessness (aRR = 4.02, 95% CI = 2.74-0.26), stimulant use disorder (aRR = 3.30, 95% CI = 2.23-4.87), crack use (aRR = 2.82, 95% CI = 1.85-4.29), and cocaine use (aRR = 1.89, 95% CI = 1.17-3.06). Intervention research should focus on housing and mental health services, and how to mitigate their impact on HIV healthcare. Intervention research is greatly needed as current tools may not be sufficient to tackle the issue of stimulant use disorder and its effects on ART adherence.

In 2017, the Health Resources and Services Administration's HIV/AIDS Bureau funded an Evaluation Center (EC) to assess the rapid implementation of 11 evidence-informed interventions at 25 HIV care and treatment providers across the U.S. The EC conducted an implementation science-based evaluation, including longitudinal assessment of implementation outcomes as defined by Implementation Outcome Framework (IOF) of the Conceptual Model for Implementation Research. The EC adapted a measure originally designed for implementation readiness to capture seven implementation outcomes and administered the measure to site leadership every six months, from intervention launch through the end of the initiative. The adapted measure demonstrated adequate internal consistency within and across time periods. Individual outcomes changed over the course of implementation, with the greatest period of growth during the first six months. Longitudinal relationships between outcomes posited to be most relevant at early, mid- or late-implementation were not evident in these analyses; rather, relationships between the outcomes were significant within time periods. Finally, there were differences in the trajectory of outcomes based on characteristics of the site's larger context. The use of this adapted measure across multiple implementation settings, assessing multiple interventions, is an important step forward in the comparability of implementation outcomes more broadly.

Women who inject drugs (WWID) are disproportionately affected by HIV and experience multiple barriers to PrEP use. We conducted a mixed methods study to assess PrEP awareness, interest, and use, and determinants of PrEP utilization among WWID at three community sites in Seattle, Washington from March-May 2023. Participants were ≥ 18 years old, spoke English, identified as women, had a history of injecting drugs, and self-reported a negative or unknown HIV status. We describe survey participant characteristics (n = 30) by PrEP candidacy based on behaviors associated with HIV acquisition. We concurrently recruited 16 WWID for semi-structured interviews, which were analyzed using the Rapid Assessment Process. Survey and interview data were triangulated to enhance interpretations. Among 30 WWID, 25 (83%) were PrEP candidates, of whom 19 (76%) had heard about PrEP; only 2 (8%) were currently using PrEP. Among PrEP candidates, 13 (57%) reported interest in daily oral PrEP and almost half (n = 12, 48%) reported interest in injectable PrEP. Qualitative data revealed cursory PrEP knowledge and a strong interest in daily oral and injectable PrEP among those who perceived they were at risk for HIV. Several barriers to PrEP use were noted including housing instability, adherence challenges, limited perceived risk, and competing priorities like safety and substance use. While most WWID were aware of PrEP, qualitative data suggested significant misconceptions about PrEP, and many described complex, intersecting barriers to use. Our findings highlight the need for increased low-barrier, population-specific interventions to improve uptake and sustained use of PrEP among WWID.

More than half of adults with HIV in the United States are aged 50 or older. Older people with HIV (OPWH) are disproportionately affected by age-related health disparities and non-communicable diseases associated with inflammation. The current pilot randomized controlled trial (RCT) evaluated the feasibility and acceptability, while exploring signals of effects of a transdiagnostic cognitive behavioral therapy (CBT) modular group teaching skills to cope with distress, make positive health behavior changes, and ultimately reduce inflammation. Participants were 31 virally undetectable, and psychiatrically stable OPWH (age [Formula: see text]50 years). Participants were randomized 1:1 to enhanced usual care or CBT for HIV and Symptom Management (CHAMP). CHAMP consists of 12-weekly virtual group sessions led by two interventionists. Self-report questionnaires and intravenous blood draws were collected at baseline and follow-up. Intervention participants completed an exit interview. Of those screened eligible, 96.8% (30/31) were randomized (n = 15 per group), 86.7% (13/15) completed the intervention, and 87% (26/30) completed the follow-up. On acceptability questionnaires scaled 0-3, participants reported high satisfaction and the intervention to be of high quality (M(SD)=3.00(0.0) for both). They also indicated their needs were met (2.67(0.50)) and coping improved (2.60(0.52)). Intervention participants showed a mean decrease in anxiety (-1.07(6.08)) and depressive (-1.71(5.37)) symptoms on clinical screeners, and mean increase in quality of life (2.86(3.59)). CHAMP is both feasible and acceptable for OPWH. Exploratory analyses indicate favorable outcomes for improving psychological distress and health-related quality of life.

This study investigated regional differences in short-term mobility patterns among men who have sex with men (MSM) in Guangdong Province, and explored the associations with risky sexual behaviors. An online survey was conducted from June to August 2023, collecting socio-demographic information, intra-provincial mobility details and sexual behaviors. Among 1,808 participants, 60% reported moving within the province over the past six months, primarily for tourism, business/work, or visiting family and friends. Participants were categorized into Pearl River Delta (PRD) and Non-Pearl River Delta (Non-PRD) regions. Significant differences in education level and income were observed between mobile and non-mobile MSM in both areas (p < 0.05). Logistic regression revealed that mobile MSM, relative to non-mobile MSM, were more likely to engage in risky sexual behaviors, with adjusted odds ratios (aORs) for multiple partners, commercial sex, and sexualized drug use ranging from 1.44 to 2.96 in PRD and 2.67 to 4.44 in Non-PRD. Additionally, associations between mobility and behaviors such as having casual partners, group sex, and inconsistent condom use with casual partners were exclusively identified in Non-PRD. These findings indicate that mobility among MSM in Guangdong Province is substantial and follows similar patterns in both regions. Mobile MSM exhibit higher rates of risky sexual behaviors, with notable regional disparities. Addressing the impact of short-term mobility on risky sexual behaviors among MSM is crucial, considering regional variations.

Common mental disorders (CMDs) are prevalent among people living with HIV (PWH) and cause morbidity, jeopardize HIV care engagement, and worsen HIV outcomes. In Vietnam, PWH who inject drugs are at high risk for poor HIV and CMD outcomes. However, few evidence-based interventions are available to address this population. We conducted a three-arm individually randomized pilot trial assigning 75 PWH with opiate use disorder and a CMD from methadone maintenance treatment clinics to either FB by a professional counselor, FB by a peer counselor, or enhanced usual care. Primary outcomes were feasibility, acceptability, and fidelity of FB; we also assessed preliminary indicators of CMD improvement and HIV care engagement. Feasibility was high, with 99% retention at 6 weeks and 96% retention at 6 months. 100% of patients receiving FB attended all 6 weekly sessions. Acceptability of FB was high for participants in both the professional and peer counselor groups. Providers were highly satisfied with the FB experience. Fidelity was adequate: 72% of professional counselors met or exceeded fidelity expectations, while 44% of peer counselors did. Preliminary indicators of effectiveness for CMDs were promising. Participants in the professional counselor arm had the greatest improvement as measured by CMD symptom improvement and CMD response rates at most follow-up visits. The adapted FB intervention should be scaled up and evaluated in a larger, fully powered randomized controlled trial to evaluate its efficacy in improving CMDs and HIV engagement for PWH and CMDs at greatest risk of poor HIV and CMD outcomes.Clinical Trial Number: NCT04790201 registered 3/10/2021.

Disengagement from antiretroviral therapy (ART) is highest in the early treatment period (≤ 6 months after initiation/re-initiation), but low intensity models designed to increase retention generally exclude these clients. We describe client preferences for HIV service delivery in the early treatment period. From 9/2022 to 6/2023, we surveyed adult clients who were initiating or on ART for ≤ 6 months at primary health facilities in South Africa and Zambia. We collected data on experiences with and preferences for HIV treatment. We enrolled 1,098 participants in South Africa (72% female, median age 33) and 771 in Zambia (67% female, median age 32), 38% and 34% of whom were initiating/re-initiating ART in each country, respectively. While clients expressed varied preferences, most participants (94% in South Africa, 87% in Zambia) were not offered choices regarding service delivery. 82% of participants in South Africa and 36% in Zambia reported receiving a 1-month supply of medication at their most recent visit; however, South African participants preferred 2- or 3-month dispensing (69%), while Zambian participants preferred 3-or 6-month dispensing (85%). Many South African participants (65%) would prefer to collect medication in community settings, while Zambian participants (70%) preferred clinic-based collection. Half of participants desired more one-on-one counselling and health information. Most participants reported positive experiences with providers, but long waiting queues were reported by South African participants.During the first six months on ART, many clients would prefer less frequent clinic visits, longer dispensing intervals, and frequent, high-quality counselling. Care models for the early treatment period should reflect these preferences.Registration: Clinicaltrials.gov NCT05454839, Clinicaltrials.gov NCT05454852.

HIV testing and pre-exposure prophylaxis (PrEP) are recommended in Germany for individuals at increased HIV risk. However, data on HIV testing, PrEP use, and PrEP knowledge among trans and non-binary people are limited. We analysed data from the 'Sexuelle Gesundheit in trans und nicht-binären Communitys' (TASG) study, a participatory study on HIV/STI and sexual health among trans and non-binary people in Germany. The study was designed, promoted, and analysed with active involvement of community members. Participants were invited to complete an anonymous online survey between 1 March and 1 July 2022. The outcomes included HIV testing within the last 5 years, PrEP use, and PrEP-specific knowledge. Predictors for HIV testing were identified using a bootstrap stepwise selection procedure. Among 2468 HIV-negative participants with information on potential HIV risks, 21.5% had potential needs for HIV testing and PrEP. Of these, only 44.3% (208/470, missing: 60) reported testing for HIV within the last 5 years. Older participants, those living in larger cities, and those with higher education levels were more likely to have tested for HIV. Additionally, only 8.3% (38/459, missing: 71) reported ever using PrEP. Among 451 participants with potential PrEP needs (missing: 79), only 57.4% knew at least one of three key PrEP-related facts at the time of the survey. Our findings highlight substantial gaps in HIV testing and prevention among trans and non-binary individuals in Germany with potential needs for these services. Reducing barriers to testing and prevention is essential to enable broader access to these critical services.

This study assessed disparities in pre-exposure prophylaxis (PrEP) use among transgender and gender expansive youth and young adults (N = 477) between 15 and 24 years old in the CARES (ATN 149) and TechStep (ATN 160) study protocols within the National Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN). Structural equation modeling was used to test mediation pathways between gender identity and PrEP uptake among the full sample and stratified by sex assigned at birth. Lifetime PrEP uptake was higher among those assigned male at birth (26%) versus assigned female at birth (9%), explained by greater structural and behavioral risks and perceived need for PrEP, especially among trans women. Among those assigned female at birth, PrEP uptake was higher among trans men (12%) than nonbinary participants (6%). Our findings characterize key structural and behavioral drivers of PrEP use and highlight the need to reduce barriers to healthcare for trans youth, particularly in the South.
