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 aimed to measure the pooled estimate of willingness to use HIV pre-exposure prophylaxis (PrEP) (WTUP) among PrEP-naïve United States (U.S.)-based men who have sex with men (MSM). PubMed, Embase, Web of Science, CINAHL, and PsycINFO were searched. The search strategy contained the keyword willingness and interest and the MeSH terms for HIV and PrEP. Articles were included if they were published between January 2005 and May 2022, reported quantitative data on WTUP among PrEP-naïve US-based MSM, and were available as full text in English. Meta-analysis was conducted to assess the pooled effect size of WTUP prevalence using a random-effects model, heterogeneity in the pooled estimate was assessed, and subgroup analyzes were conducted. Fifteen studies were included based on the inclusion and exclusion criteria. Meta-analysis revealed a pooled prevalence proportion for WTUP of 0.58 (95% CI 0.54-0.61) (or 58 out of 100) among PrEP-naïve MSM. High inter-study heterogeneity (Q = 548.10, df = 19, p < 0.01, I2 = 96.53, τ2 = 0.09) was observed. Age of the study sample and region where the data were collected significantly moderated the pooled WTUP estimate. Age-appropriate PrEP related messaging and a focus on HIV priority areas of the U.S. would be important strategies to improve WTUP among MSM in the U.S. moving forward.

Abstract
BACKGROUND There is limited understanding of the pre-exposure prophylaxis (PrEP) care continuum specific to Latino/x gay, bisexual, and other sexual minority men (SMM) that encompasses the population residing outside of large metropolitan or urban areas. SETTING We examined trends and characteristics associated with the PrEP care continuum with data from the 2014-2020 cycles of the American Men's Internet Survey, an annual online cross-sectional behavioral survey of cisgender SMM in the United States. METHODS We calculated PrEP continuum outcomes overall and by year among Hispanic/Latino SMM (n = 9010). We used generalized estimating equations with Poisson links to examine (1) temporal trends (2014-2020) in each step of the PrEP continuum and PrEP use in the past year stratified by PrEP eligibility and (2) correlates of each step of the PrEP continuum in 2020 using multivariable models. RESULTS Among 2283 Latino SMM in 2020, 84% reported PrEP awareness, 30% discussed PrEP with a provider, 15% used PrEP in the past year, and 12% were currently using PrEP. PrEP awareness increased from 52% in 2014 to 84% in 2020; and PrEP use in the past year increased from 4% in 2014 to 15% in 2020. In the multivariable models, age and PrEP eligibility were associated with PrEP use in the past year, and urban-rural classification was associated with current PrEP use. CONCLUSIONS While most of the Latino SMM are aware of PrEP, significant gaps remain in this population in discussing PrEP with a provider and using PrEP that require tailored strategies to enhance access to HIV prevention services.

Abstract
BACKGROUND Miami, Florida is an epicenter of the HIV epidemic in the US, with 20% of new HIV infections occurring in women. Despite effectiveness of Pre-Exposure Prophylaxis (PrEP) in preventing HIV, only 10% of eligible women benefit from its use. SETTING This study evaluates PrEP awareness and use, and factors associated with PrEP awareness among sexually active women in Miami, Florida. METHODS Results reported in this study included cross-sectional data that were collected as part of a baseline visit from a parent study. Cis-gender, HIV-negative, 18-45-year-old, sexually active women were recruited as part of a study evaluating recurrent bacterial vaginosis and HIV risk. Participants completed questionnaires assessing socio-demographics, HIV risk factors, prior history of HIV testing and reproductive tract infections, PrEP awareness and use. Relationships between variables and PrEP awareness were analyzed and multivariable logistic regression identified variables strongly associated with PrEP awareness. RESULTS Among the 295 women enrolled, median age was 31 (24-38) years, 49% Black, 39% White, and 34% Hispanic. Of 63% who knew about PrEP, only 5% were on PrEP. Women with income below poverty line (OR = 2.00[1.04,3.87];p = 0.04), more male sexual partners in past month (OR = 1.30[1.01,1.68];p = 0.04), lifetime HIV testing (OR = 6.42[2.83,14.52];p<0.01), and current bacterial vaginosis (OR = 2.28[1.18,4.40];p = 0.01) were more likely to be aware of PrEP. Lower odds of PrEP awareness were associated with being Black (OR = 0.38[0.15,0.96];p = 0.04), Hispanic (OR = 0.18[0.08,0.39];p<0.01), heterosexual (OR = 0.29[0.11,0.77];p<0.01), and reporting inconsistent condom use during vaginal sex (OR = 0.21[0.08,0.56];p<0.01). CONCLUSION PrEP awareness is low among reproductive age women in a high-risk setting. Culturally tailored interventions are needed to increase PrEP awareness and uptake, especially among Black and Hispanic women with inconsistent condom use during vaginal sex with male partners.

Abstract
The amount and type of information individuals receive about HIV pre-exposure prophylaxis (PrEP) may influence PrEP uptake. We surveyed 331 HIV-negative sexual and gender minorities who have sex with men at a Midwestern Pride festival in 2018 (Mage = 32, 68% White, 87% cisgender men) to assess sources and perceived tone of PrEP information and associated outcomes. Most participants (88%) had heard about PrEP. The most common sources were the internet (70%), social media (59%), and friends (54%). Messages from health campaigns were perceived as most positive and those from religious institutions as least positive. Sources differed based on demographics. Controlling for indications for PrEP use, those who heard about PrEP from health campaigns and those who heard more positive messages reported lower levels of PrEP stigma, βs = -0.27--0.23, ps < .05. Non-users who heard about PrEP from the internet had stronger intentions to use PrEP, β = 0.28, p < .05. Those who heard about PrEP from sexual partners and health campaigns were more likely to discuss PrEP with providers, PRs = 1.60-1.80, ps < .01. Finally, those who heard about PrEP from friends and partners were more likely to use PrEP, PRs = 2.01-2.24, ps < .05. Leveraging sexual partners, social network members, and health campaigns are promising avenues to advance PrEP implementation.

Abstract
Men who have sex with men (MSM) are disproportionately impacted by HIV in the United States, and substance use and compulsive sexual behavior (CSB) are contributors to HIV risk behavior. This study sought to examine the direct and interactive effects of concurrent substance use and CSB on condomless anal sex (CAS) in a community sample of MSM (N = 200) utilizing a 90-day timeline follow-back assessment. Results indicated CSB did not directly increase risk for CAS when controlling for substance use and age. There was limited evidence for a direct effect of concurrent alcohol use on CAS, and no evidence for an interaction effect with CSB. The relationship between concurrent drug use and CAS was moderated by CSB, such that concurrent drug use was positively associated with CAS for those who screened positive for CSB, while the association was non-significant for those who screened negative. Implications and limitations of these findings are discussed.

Abstract
Despite the increasing availability of pre-exposure prophylaxis (PrEP), Latinx men who have sex with men (LMSM) are not receiving PrEP-related information. To understand the influence of LMSM sexual networks on PrEP-related conversations and encouragement to use PrEP, this cross-sectional egocentric network study characterized the PrEP-related communication of 130 LMSM egos with 507 sexual partners (alters). Participants were recruited using respondent-driven sampling methods from a Miami-Dade County community-health organization. Egocentric-level data were collected from 2018-2019 and analyzed using multilevel modeling. Of egos, 30% reported using PrEP. Closeness between participants and sexual partners played a role in PrEP conversation and encouragement. Participants believed they would have less success convincing sexual partners to use PrEP if partners were older. Participants perceived higher likelihood to talk about PrEP or success in encouraging alters to use PrEP if, relative to meeting sexual partners on Grindr, they met at a friend's party, gay-centric community event, or school/work. Given that increased closeness and in-person sexual partner meeting venues are associated with PrEP information dissemination and encouragement, social network-based interventions can capitalize on PrEP navigators who run network visualizations, and with this information develop a longitudinal plan to increase PrEP conversation and encouragement as needed for each network.

Abstract
OBJECTIVE To determine the feasibility, acceptability, and implementation of a HIV self-test (HIVST) program through PrEP clients' social and sexual networks. BACKGROUND HIV testing is critical for treatment and prevention engagement. HIVST kits can overcome barriers to testing. A negative result is an opportunity to provide PrEP information. We describe implementation factors associated with engaging current Mobile PrEP (MP) clients to distribute HIVST kits and PrEP information through their networks. SETTING Community venues in Miami-Dade County, Florida. METHODS A baseline survey collected network information and explored distribution plans for offering HIVST kits. A follow-up survey evaluated use and distribution. A logic model describes the process of implementation and evaluation. Up to 4 Ora-Quick HIV ST kits were offered to 81 MP clients. A brief training included resources for posttest engagement. RESULTS Forty-four percent of the kits were reported as distributed. Of 81 MP clients offered kits, 50 (62%) accepted. In a follow-up survey, 77% of MP clients distributed at least 1 kit. Fifty-six (86%) social network members were Latino, and 9 (14%) were Black. Three of 4 MP clients engaged in PrEP discussions (77%) with SN members. Reported reasons for HIVST kit use included convenience, confidentiality, privacy concerns, and discomfort with going to a testing site. MP clients reported that kit distribution was affected by the COVID-19 pandemic. CONCLUSION HIV ST kits allowed PrEP users to engage others in their social and sexual networks for HIV testing and information regarding PrEP. Work to scale-up this intervention is underway.

Abstract
Despite the wide availability of PrEP, Latino men who have sex with men (LMSM) continue to experience access barriers. Novel HIV prevention research strategies to increase PrEP uptake and adherence among the high incidence populations, such as LMSM who misuse drugs, include social network analyses. This study identified the associations of drug use homophily within LMSM friendship networks and PrEP promotion conversations and described the physical overlap between geographic drug risk areas with conversations of PrEP promotion. Respondent-driven sampling was used to recruit 10 sociocentric networks. Quadratic assignment procedure (QAP) correlations and multiple regression QAPs were used to identify influences of drug use homophily, and geocoding and visualizations to describe drug use polygons and PrEP conversations. Friendship relationships in which both friends used cocaine or marijuana were more likely to report PrEP-related conversations in the past six months. The likelihood of talking about PrEP in the next six months was higher among dyads with cocaine use homophily and ecstasy use homophily, while lower among dyads with marijuana use homophily. Participants reported using marijuana and cocaine throughout Miami-Dade County while ecstasy polygons were mostly in urban areas. The majority of drug polygons associated with PrEP conversations were located in north and central Miami. Future interventions can consider enrolling entire sociocentric friendship groups, configuring friendship networks to connect those without PrEP information to those with information, and incorporating peer leaders.

Abstract
BACKGROUND US Latino men who have sex with men (LMSM) are a group at highest risk for HIV. One driver of HIV among LMSM is inadequate access to pre-exposure prophylaxis (PrEP) information. The social network theory of homophily suggests that sharing similar sociodemographic factors could influence PrEP conversations within networks. This study aimed to determine how the effects of homophily across sociodemographic, immigration, cultural, and PrEP-related factors are associated with PrEP-related communication. SETTING This study was conducted in Miami-Dade County, FL. METHODS Data collected between August 2018 and October 2019 included 10 sociocentric friendship groups of 13 LMSM (N = 130). Participants were recruited using respondent-driven sampling by a community-based organization in Miami. We used the multiple regression quadratic assignment procedure to identify the effects of homophily and relationship characteristics on PrEP-related conversations using R software. RESULTS More frequent PrEP-related conversations were associated with dyadic friendships characterized by homophily on knowledge of PrEP effectiveness, heterophily on depressive symptom severity, home addresses proximity, friend closeness, and interaction frequency. Past PrEP-related conversation frequency also increased based on heterophily on the Latino cultural value of familism (ie, emotional support to family). Racial homophily, heterophily on severity of depressive symptoms, home addresses proximity, friendship closeness, and frequency of interactions increased likelihood to encourage a friend to use PrEP. DISCUSSION Social and spatial closeness and homophily play a role in PrEP-related conversations. Information from social networks contextualized in geographic settings can be elucidated to contribute toward the design of novel opportunities to end HIV.

PrEP Use and PrEP Use Disclosure are Associated with Condom Use During Sex: A Multilevel Analysis of Latino MSM Egocentric Sexual Networks. AIDS Behav 2021; 25:1636-1645.

Abstract
Pre-exposure prophylaxis (PrEP) is integral to HIV prevention; however, the influence of PrEP use and PrEP use disclosure on condom use is unclear among Latinx men who have sex with men (LMSM). This study explored associations of LMSM PrEP use and use disclosure on consistent dyadic condom use in the past 6 months. Participants were 130 HIV-negative PrEP and non-PrEP using LMSM ages 20-39 years. Two-level logistic regression models assessing individual- and dyadic-level predictors on condom use were fitted using R. Participants reported a mean of four sexual partners (n = 507 dyads). Participants who reported using PrEP or having more sexual partners were more likely to use condoms; however, participants who reported disclosing PrEP use were less likely to use condoms. Future longitudinal studies should characterize approaches to increase informed personal health choices and conversations about PrEP, condom use, and other HIV risk-reduction strategies using network methodologies.

Abstract
Despite increasing availability of pre-exposure prophylaxis (PrEP), HIV prevention efforts have stalled. It is important to study potential barriers to HIV prevention methods, such as pre-exposure prophylaxis stigma. This study aims to develop and validate the Community PrEP-related Stigma Scale (Community-PSS) to address gaps in the literature. Participants were 108 sexual and gender minority men recruited through virtual and community-posted advertisements in Florida. The authors assessed reliability using Cronbach's alpha analysis, determined scale components using principal component analysis, and assessed construct validity based on five a priori hypotheses. The scale had high internal consistency (α = 0.86) and four components (stigma of actions outside of sex, stigma of sexual actions, extreme stigma perceptions, and positive community perception). The Community-PSS was valid, supporting four out of five hypotheses and in the expected directions. The Community-PSS was a valid and reliable tool in the sample and correlates with a previously validated PrEP stigma scale, HIV knowledge, PrEP knowledge, and likelihood of condom use with a partner on PrEP.

Abstract
In 2017, Florida ranked 2nd nationally in prevalence and incidence rates of HIV infections in the United States. Due to the high burden of HIV and low viral suppression in Florida, it is of increased importance to study methods of HIV prevention such as preexposure prophylaxis(PrEP) in this state. Our study aimed to examine correlates of PrEP awareness among PLWH in Florida and describe patterns of PrEP awareness/information sources. Using data collected from the Florida Cohort study between 2014 and 2018, 530 PLWH answered items that were hypothesized to be correlated with PrEP awareness. Of our sample, 53.8% were aware of PrEP. Urban location of recruitment, sexual partner's use of PrEP, use of viral suppression as an HIV prevention strategy, and engagement in transactional sex were all significantly associated with higher odds of PrEP awareness. Care providers and HIV/AIDS support groups were the most frequently listed sources of PrEP awareness, sources of future PrEP information, and most trusted sources for PrEP information. Findings from this study could inform future interventions that aim to increase PrEP awareness among PLWH to increase PrEP awareness and uptake among their HIV-negative social and sexual networks.

Abstract
Despite its proven effectiveness in reducing HIV transmission, pre-exposure prophylaxis (PrEP) use remains low. This study used data from a 2017-2018 U.S. national cohort to investigate social influences on PrEP experience and future PrEP use among cisgender men who have sex with men. We used descriptive statistics and multivariable logistic analyses to examine social influences (e.g., how participants heard about PrEP and number of persons they knew taking PrEP) associated with each previous PrEP use and intentions to use PrEP. Among participants who knew of PrEP, commonly reported ways of first hearing about PrEP were through social media (27.4%) and friends (26.8%). These were also cited top influences on participants' current attitudes toward PrEP (friends 23.5%, social media 22.1%). Multivariable logistic regression analyses found that knowing more people taking PrEP was associated with increased odds of previously using PrEP and intending to use PrEP. Friends and social media were common and influential sources of information regarding PrEP. Results suggest that tapping into these social connections may effectively disseminate public health messaging about PrEP and encourage use among key populations to reduce HIV burden.
