Abstract
Despite the availability of pre-exposure prophylaxis (PrEP), Latino sexual minority men (LSMM) continue to experience disparities in PrEP uptake and subsequently, HIV vulnerability. Social network norms are an underutilized solution to increase PrEP uptake. We used a peer influence model (network autocorrelation model) to examine the role of social network descriptive norms (i.e., actual behaviors) surrounding PrEP use. A total of 11 sociocentric networks of 13 friends (n = 143 LSMM) were recruited into our study from 2018 to 2019 in South Florida. Most participants were in PrEP pre-contemplation (n = 44), and almost one-third of our sample were using PrEP (n = 38). Three network autocorrelation models were estimated using an empirically informed Bayesian analysis. We found a positive association between participants' Motivational PrEP Cascade (MPC) position and their network members' (friends') cascade position based on three different measures of connection even when accounting for PrEP knowledge: friendship (ρ = 0.22; 95% CIa = 0.01-0.42), emotional closeness (ρ = 0.24; 95% CI = 0.03-0.44), and frequency of interaction (ρ = 0.22; CI = 0.03-0.42). Our findings highlight that an individual's progress in the MPC may be influenced by their network members' progress in the MPC, suggesting that LSMM using PrEP may serve as role models to their peers for PrEP use due to descriptive norms. Our findings further suggest that PrEP interventions for LSMM along the MPC can be implemented at the social network level.

Abstract
This study measures changes in condomless anal sex (CAS) among HIV-negative men who have sex with men (MSM) who are not taking pre-exposure prophylaxis (PrEP). It considers the 2014-2019 cycles of the American Men's Internet Survey, a serial, cross-sectional web-based survey of US cisgender MSM aged ≥ 15 years, in which ~ 10% of each year's sample is drawn from the previous year. Among those surveyed for 2 years who remained HIV-negative and off PrEP, reports of having any CAS and of CAS partner number were compared across years. We disaggregated by partner HIV status, and considered demographic predictors. The overall population saw a significant 2.2 percentage-point (pp) increase in reports of any CAS year-over-year. Sub-populations with the largest year-on-year increases were 15-24-year-olds (5.0-pp) and Hispanic respondents (5.1-pp), with interaction (young Hispanic respondents = 12.8-pp). On the relative scale, these numbers correspond to 3.2%, 7.2%, 7.3% and 18.7%, respectively. Absolute increases were concentrated among partners reported as HIV-negative. Multivariable analyses for CAS initiation found effects concentrated among Hispanic and White youth and residents of fringe counties of large metropolitan areas. CAS partner number increases were similarly predicted by Hispanic identity and young age. Although condom use remains more common than PrEP use, increasing CAS among MSM not on PrEP suggests potential new HIV transmission pathways. Concentration of increases among 18-24-year-old MSM portends future increases in the proportion of newly diagnosed HIV that occur among youth. Concentration among young Hispanic MSM will likely expand existing disparities. Although reducing barriers to PrEP remains vital, condom promotion for MSM remains a key public health practice and appears to be missing key audiences. LGBTQ+-inclusive sex education is one avenue for enhancing these efforts.

HIV/Pre-Exposure Prophylaxis Knowledge and Acceptability of Rapid HIV Testing Among Transgender Adolescents in a Multidisciplinary Gender Clinic. Transgend Health 2024; 9:128-135.

Abstract
Purpose The objectives of this study were to assess the knowledge of HIV and pre-exposure prophylaxis (PrEP) in transgender adolescents and young adults (AYAs) and to test the acceptability of rapid HIV testing among transgender adolescents in a multidisciplinary gender clinic. Methods Participants enrolled on the same day as their mental health or medical appointment in a multidisciplinary gender clinic. They completed survey questions regarding HIV and PrEP knowledge and were also offered an optional same-day, rapid, fourth-generation HIV test. Participants who had an HIV test answered additional questions about their testing experience. Results We enrolled 61 participants; just over half (n=31) were assigned female at birth. Less than a third (n=20, 32.8%) scored 80% or above regarding HIV knowledge. Nearly half of the participants (n=29, 47.5%) were not interested in PrEP. Forty-one percent of participants chose to have a rapid HIV test; all were "satisfied" with the testing experience. There were no positive HIV results. Conclusions Transgender AYAs have gaps in their understanding of HIV acquisition and transmission. Rapid HIV testing in the setting of gender care is well received by those who desire testing and may be a way to increase knowledge of transgender AYA HIV status.

Abstract
Low HIV risk perception is a barrier to PrEP uptake, but few studies have examined risk perception and PrEP uptake among young men who have sex with men (YMSM). We performed a secondary analysis of data collected in 2016 from YMSM ages 16-25 in the Washington, DC metropolitan area who participated in a cross-sectional online survey that aimed to identify strategies for engaging YMSM in PrEP services. Of 188 participants, 115 (61%) were considered eligible for PrEP. Among PrEP-eligible participants who had never used PrEP, 53%, 71%, and 100% with low, moderate, and high risk perception, respectively, were willing to use PrEP (Fisher's exact test p = 0.01). Odds of PrEP willingness were greater among those with moderate/high versus low risk perception (adjusted odds ratio [OR] = 5.62, 95% CI = 1.73-18.34). HIV risk perception was not significantly associated with self-reported PrEP use. These findings suggest the importance of risk perception as a correlate of willingness to use PrEP, which is a key step in existing frameworks of PrEP uptake.

Randomized Controlled Trial of Automated Directly Observed Therapy for Measurement and Support of PrEP Adherence Among Young Men Who have Sex with Men. AIDS Behav 2023; 27:719-732.

Abstract
Measurement of adherence to oral pre-exposure prophylaxis (PrEP) in real-time has been challenging. We developed DOT Diary, a smartphone application that combines automated directly observed therapy with a PrEP adherence visualization toolkit, and tested its ability to measure PrEP adherence and to increase adherence among a diverse cohort of young men who have sex with men (MSM). We enrolled 100 MSM in San Francisco and Atlanta and randomly assigned them 2:1 to DOT Diary versus standard of care. Concordance between DOT Diary measurement and drug levels in dried blood spots was substantial, with 91.0% and 85.3% concordance between DOT Diary and emtricitabine-triphosphate and tenofovir-diphosphate, respectively. There was no significant difference in the proportion of participants with detectable PrEP drug levels at 24 weeks between study arms. These results suggest DOT Diary is substantially better than self-reported measures of adherence, but additional interventions are needed to improve PrEP adherence over time.
