Pre-exposure prophylaxis (PrEP) reduces sexual risk for HIV transmission by 99% when used appropriately, but remains underutilized among gay, bisexual, and other men who have sex with men (MSM). In this mixed-method study, we describe reasons for PrEP refusal associated with low self-perceived need for PrEP among MSM who recently declined daily oral PrEP when offered by a provider. Data are from a quantitative behavioral survey of MSM (N = 93) living in Atlanta, Chicago, and Raleigh-Durham, who also either responded to an in-depth interview (n = 51) or participated in one of 12 focus groups (n = 42). Themes of low self-perceived need for PrEP were: low self-perceived risk for HIV acquisition (33% of respondents); confidence in remaining HIV-negative (35%); using condoms (81%); limiting number of partners and choosing partners carefully (48%); asking partners about their HIV status before having sex (45%); engaging in safer sexual positions or oral sex (28%); being in a monogamous relationship or exclusivity with one partner (26%); and regular HIV testing (18%). Low self-perceived risk for HIV acquisition and high confidence in other prevention strategies were important factors related to low self-perceived need in MSM refusing daily oral PrEP when offered. Providers should continue to discuss the benefits of PrEP as a safe and highly effective option for HIV prevention.

OBJECTIVES: Effective health communication can increase intent to vaccinate. We compared 8 messages that may influence parents' intent to vaccinate their children against COVID-19. METHODS: In a cross-sectional survey of adults in the United States administered online in August 2021, 1837 parents and legal guardians were exposed to 8 messages (individual choice, gain/practical benefits, nonexpert, health care provider recommendation, altruism/community good, safety/effectiveness, safety, and effectiveness) to determine message reception and influence on intent to vaccinate their children. Parents responded to 10 questions using a Likert scale. We computed odds ratios (ORs) for each message, with an OR >1.0 indicating greater observed odds of participant agreement with the follow-up statement as compared with a reference message. We compared outcomes individually across messages with ordinal logistic regression fit using generalized estimating equations. RESULTS: The individual choice message had the highest odds of agreement for understanding intent (OR = 2.10; 95% CI, 1.94-2.27), followed by the health care provider recommendation message (OR = 1.58; 95% CI, 1.46-1.71). The individual choice message had the highest odds of memorability, relatability, and trustworthiness. The altruism/community good message was at or near second best. The altruism/community good message had the highest or near-highest odds of increasing parents' intent to vaccinate their children, asking friends and family for their thoughts, and searching for additional information. The message that most motivated parents to vaccinate their children depended on parental intent to vaccinate prior to being exposed to the tested messages. CONCLUSIONS: Messages with themes of individual choice, health care provider recommendation, and altruism/community good may be used in future message campaigns. Further research is needed to refine message concepts related to altruism/community good.

OBJECTIVE: Public health agencies have a critical role in providing effective messaging about mitigation strategies during a public health emergency. The objectives of this study were (1) to understand perceptions of COVID-19 vaccines, including concerns about side effects, safety, and effectiveness and how these perceptions influence vaccine decision-making among US adults and (2) to learn what messages might motivate vaccine uptake. METHODS: In April and May 2021, we conducted 14 online focus groups with non-Hispanic English-speaking and English- and Spanish-speaking Hispanic adults (N = 99) not vaccinated against COVID-19. We oversampled adults aged 18-39 years and rural residents and systematically assessed 10 test messages. Researchers used a standardized guide and an a priori codebook for focus group discussions, coding transcripts, and thematic analysis. RESULTS: Vaccine hesitancy factors included fear of the unknown; long-term side effects, including infertility; and beliefs that the vaccines were developed too quickly and were not sufficiently effective. Motivating factors for receiving vaccination included the ability to safely socialize and travel. Health care providers were considered important trusted messengers. Participants were critical of most messages tested. Messages that came across as "honest" about what is not yet known about COVID-19 vaccines were perceived more positively than other messages tested. Messages were seen as ineffective if perceived as vague or lacking in data and specificity. CONCLUSIONS: Messages that were simple and transparent about what is unknown about vaccines relative to emerging science were viewed most favorably. Health care providers, friends, and family were considered influential in vaccination decision-making. Findings underscore the benefits of research-informed strategies for developing and disseminating effective messages addressing critical issues in a public health emergency.

INTRODUCTION: The United States Centers for Disease Control and Prevention currently recommends HIV screening at least annually among sexually active gay, bisexual and other men who have sex with men (MSM), but only half report being tested in the past year in the United States. As HIV self-test kits are becoming more available around the United States via web and app-based interventions, it is important to understand who is willing and able to order them. This analysis sought to better understand predictors of free HIV self-test kit utilization among MSM in M-cubed, an HIV prevention mobile app intervention trial in Atlanta, Detroit and New York City. METHODS: We conducted an exploratory secondary analysis of self-report and in-app data collected from the intervention arm of the M-Cubed study from 24 January 2018 to 31 October 2019. Behavioural, demographic and other potential predictors of HIV self-test ordering were identified from Social Cognitive Theoretical underpinnings of the app, and from the literature. Significant predictor variables in bivariate analyses were considered for inclusion in the empiric multivariable model. Demographic variables chosen a priori were then added to a final model estimating adjusted prevalence ratios (aPR). RESULTS: Over half of the 417 intervention participants ordered an HIV self-test kit during the study. In bivariate analyses, ordering a kit was associated with HIV testing history, plans to get tested and reported likelihood of getting tested. In the final model, participants were more likely to order a kit if they reported plans to get tested in the next 3 months (aPR = 1.58, 95% CI: 1.18-2.11) or had not tested for HIV in the past 3 months (aPR = 1.38, 95% CI: 1.13-1.70). There was no difference in HIV self-test kit ordering by income, race/ethnicity or age. CONCLUSIONS: HIV testing is an important tool in ending the HIV epidemic and must be accessible and frequent for key populations. This study demonstrates the effectiveness of HIV self-test kits in reaching populations with suboptimal testing rates and shows that self-testing may supplement community-based and clinical testing while helping overcome some of the structural barriers that limit access to annual HIV prevention services for MSM.

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) continue to be overrepresented in human immunodeficiency virus (HIV) infection in the United States. HIV prevention and care interventions that are tailored to an individual's serostatus have the potential to lower the rate of new infections among GBMSM. Mobile technology is a critical tool for disseminating targeted messaging and increasing uptake of basic prevention services including HIV testing, sexually transmitted infection (STI) testing, and pre-exposure prophylaxis (PrEP). Mobile Messaging for Men (M-Cubed) is a mobile health HIV prevention intervention designed to deliver video- and text-based prevention messages, provide STI and HIV information, and link GBMSM to prevention and healthcare resources. The current report describes an iterative process of identifying and selecting publicly available videos to be used as part of the M-Cubed intervention. We also conducted interviews with GBMSM to assess the acceptability, comprehension, and potential audience reach of the selected video messages. METHODS: The selection of videos included balancing of specific criteria [e.g., accuracy of scientific information, video length, prevention domains: HIV/STI testing, antiretroviral therapy (ART), PrEP, engagement in care, and condom use] to ensure that they were intended for our GBMSM audiences: HIV-negative men who engage in condomless anal sex, HIV-negative men who do not engage in condomless anal sex, and men living with HIV. This formative study included in-person interviews with 26 GBMSM from three U.S. cities heavily impacted by the HIV epidemic-New York City, Detroit, and Atlanta. RESULTS: Following a qualitative content analysis, the study team identified five themes across the interviews: participant reactions to the video messages, message comprehension, PrEP concerns, targeting of video messaging, and prompted action. CONCLUSIONS: Study results informed a final selection of 12 video messages for inclusion in a randomized controlled trial of M-Cubed. Findings may serve as a guide for researchers who plan to develop HIV prevention interventions that utilize publicly available videos to promote behavioral change. Further, the findings presented here suggest the importance of developing videos with broad age and gender diversity for use in interventions such as M-Cubed, and in other health promotion settings.

Expanding on previous work, we present an HIV Prevention Cycle of Care model to facilitate understanding of the complexity of issues involved in pre-exposure prophylaxis implementation for gay, bisexual, and other men who have sex with men (MSM) in the USA, including individual, client-provider, and overarching issues such as health equity, stigma, and prevention nomenclature. The HIV prevention cycle of care applies to MSM who test negative for HIV. The Prevention Cycle of Care model includes seven steps: prevention knowledge, prevention self-awareness and preferences, prevention motivation, health-care access and cost, provider issues, adherence and persistence, and periodic reassessment and adjustment. HIV prevention is complex in an era of emerging multiple modalities, and more research is needed to successfully implement pre-exposure prophylaxis options over time and across diverse communities of MSM who are sexually active.

BACKGROUND: An important subgroup of gay, bisexual, and other men who have sex with men (MSM) with behavioral indications refuse daily oral pre-exposure prophylaxis (PrEP) when recommended by a provider. Emerging HIV prophylaxis products (eg, injectable, event-driven) offer more options to MSM who refuse daily PrEP. In this article, we assess reasons for refusal and likelihood to use various products among MSM who refused PrEP. METHODS: MSM who reported anal sex without condoms or PrEP and refused daily oral PrEP in the past 6 months were recruited through clinics, community venues, and online in Atlanta, Chicago, and Raleigh-Durham. Men were asked their main reason for recently refusing daily PrEP and likelihood of using various PrEP options in the future. Bivariate and multivariable regression models were used to estimate associations. RESULTS: MSM (n = 93; 70% Black, 48% age 18-29 years) reported their main reason for refusing daily PrEP were potential side effects (35%), a daily pill regimen (22%), and not having enough information (18%). Reported likelihood of using PrEP products was 58% for penile gel, 54% for event-driven oral, 52% for injectable, and 50% for daily PrEP. MSM who reported daily regimen as the main reason for refusing PrEP had greater odds of likelihood to use an injectable [adjusted odds ratio (AOR) = 5.21, 95% confidence interval (CI): 1.32 to 20.52]. Younger men (18-29 vs 30+ years) had greater odds of likelihood to use condoms (AOR = 3.40, 95% CI: 1.15 to 10.04) and daily PrEP (AOR = 2.76, 95% CI: 1.06 to 7.16); there were no product preference differences by race. CONCLUSION: Most men who refused daily PrEP indicated likelihood of using some form of PrEP in the future.

While there is strong evidence that the experience of intimate partner violence (IPV) shapes PrEP use among heterosexual women, evidence for similar relationships among gay, bisexual and other men who have sex with men (GBMSM) is scant. In this paper we analyze baseline data from a large randomized controlled trial (RCT) of an HIV prevention intervention for GBMSM recruited from three cities (Atlanta, Detroit and New York City) to examine how the recent experience of IPV shapes their rankings of PrEP delivery options. Men were asked to rank from 1 to 8 PrEP taken by daily pill, event-based pill, injection, anal suppository (before sex), suppository (after sex), gel (penile or rectal) (before sex), and gel (after sex) and condoms. The analysis sample is 694 HIV-negative, sexually active GBMSM. Analysis considers an ordinal outcome measuring participant's ranked preferences for their future use of eight HIV prevention options. Men who experienced physical IPV preferred PrEP in pill form, while men who experienced partners monitoring their behaviors (monitoring IPV) preferred PrEP by injection. Men who experienced emotional IPV ranked PrEP by pill lower than other methods. Sexual and controlling IPV were not significantly associated with PrEP modality ranking. As more modes of PrEP delivery become available, providers should be encouraged to screen GBMSM seeking PrEP for IPV, and to provide men with the necessary information to facilitate an informed choice when deciding on a PrEP modality that will work for them and their relationship context.

BACKGROUND: Gay, bisexual, and other men who have sex with men (GBMSM) face the highest burden of HIV in the United States, and there is a paucity of efficacious mobile health (mHealth) HIV prevention and care interventions tailored specifically for GBMSM. We tested a mobile app combining prevention messages and access to core prevention services for GBMSM. OBJECTIVE: To measure the efficacy of the Mobile Messaging for Men (M-cubed) app and related service to increase HIV prevention and care behaviors in diverse US GBMSM. METHODS: We conducted a randomized open label study with a waitlist control group among GBMSM (in three groups: lower-risk HIV-negative, higher-risk HIV negative, and living with HIV) recruited online and in venues in Atlanta, Detroit and New York. Participants were randomly assigned to receive access to the app immediately or at 9 months after randomization. The app provided prevention messages in six domains of sexual health and offered ordering of at-home HIV and STI test kits, receiving PrEP evaluations and navigation, and service locators. Serostatus- and risk-specific prevention outcomes were evaluated at baseline, at the end of the intervention period, and at 3, 6 and 9 months after the intervention period. RESULTS: 1226 GBMSM were enrolled and randomized; 611 were assigned to and 608 were analyzed in the intervention group, and 615 were assigned to and 611 were analyzed in the control group. For higher-risk GBMSM, allocation to the intervention arm was associated with a higher odds of HIV testing during the intervention period (aOR 2.02, 95% CI 1.11-3.66) and with a higher odds of using PrEP in the 3 months after the intervention period (aOR 2.41, CI:1.00-5.76, p<0.05). No changes in HIV prevention or care were associated with allocation to the intervention arm for the lower-risk HIV-negative or living with HIV groups. CONCLUSIONS: Access to the M-cubed app was associated with increased HIV testing and PrEP use among higher-risk HIV-negative GBMSM in three US cities. The app could be made available through funded HIV prevention providers; additional efforts are needed to understand optimal strategies to implement the app outside of the research setting.

Disparities in antiretroviral treatment (ART) access by race for men who have sex with men (MSM) with HIV persist. We assessed whether race-based medical mistrust and HIV stigma impact ART adherence among MSM with HIV. Longitudinal data were drawn from a RCT of a messaging intervention to promote sexual health among MSM. Regression models tested associations between baseline race-based medical mistrust, HIV stigma, and ART adherence at follow-up. In multivariable models with the overall sample of MSM with HIV (n = 383), baseline medical mistrust was negatively associated with ART adherence 3-months post-baseline. Among participants of color (i.e., Black/African American, Hispanic/Latino, or another race; n = 301), HIV stigma was negatively associated with optimal ART adherence 6-months post-baseline. Medical mistrust was longitudinally associated with reduced ART adherence among racially and ethnically diverse MSM with HIV. HIV-related services might prioritize patients reporting medical mistrust for additional supports.

HIV pre-exposure prophylaxis (PrEP) is a preventive medication that could reduce new infections among men who have sex with men (MSM). There are limited data on differing reasons for PrEP nonuse by condomless anal sex (CAS). We examined demographic and behavioral variables associated with PrEP use and reasons for PrEP nonuse by CAS. Data are from the M-cubed Study, collected in a 2018 baseline assessment of MSM (n = 798) in Atlanta, Detroit, and New York City. Participants reported current PrEP use (31%), previous use (8%), and never use (61%). MSM reporting CAS (adjusted odds ratio [aOR] = 2.60, confidence interval [95% CI] = 1.73-3.91), age 18-29 (aOR = 2.11, 95% CI = 1.26-3.52), 30-39 (aOR = 2.12, 95% CI = 1.25-3.59), with a college degree (aOR = 1.96, 95% CI = 1.20-3.21), or postgraduate education (aOR = 2.58, 95% CI = 1.51-4.40) had greater odds of current (vs. never) use; uninsured (aOR = 0.30, 95% CI = 0.16-0.57) men had lower odds of current (vs. never) use. For never use, more MSM who reported CAS (vs. did not) endorsed the following reasons (p's < 0.05): Insurance wouldn't cover PrEP (20% vs. 12%), Didn't know where to get it (33% vs. 24%) and fewer reported Didn't need PrEP (23% vs. 39%) and Started a committed relationship (7% vs. 25%). For discontinuation, more MSM who reported CAS (vs. did not) endorsed Worry about the safety of PrEP (19% vs. 3%). Efforts are needed to enhance PrEP as an option among older, less educated, and uninsured MSM. These findings may inform how providers can facilitate PrEP use by messaging on access and safety for MSM who reported CAS.

BACKGROUND: Daily oral pre-exposure prophylaxis (PrEP) is available and recommended for men who have sex with men (MSM) at risk for HIV infection. Other HIV prevention products are being developed, including long-acting injectable (LAI) and event-based oral and topical formulations. Understanding preferences for potential products by MSM can help direct further development of prevention messaging. METHODS: We present baseline data from HIV-negative participants enrolled in the US Mobile Messaging for Men (M-cubed) Study. Participants were asked their likelihood of and rank order preference for using daily oral PrEP and various potential prevention products (one- to -three-month injections, 2-1-1 sexual event oral dosing, anal or penile gel, or anal suppository), and their sociodemographic characteristics. Bivariate and multivariable logistics regression assessed demographic associations with likelihood of use and rank order preference. RESULTS: Overall, most MSM reported a likelihood of using LAI (74%), sexual event-based pills (67%) and penile gel (64%). Men who reported recent unprotected (condomless and PrEPless) anal sex most preferred a penile gel formulation (74%), followed closely by LAI and event-based pills (73% each). Current PrEP users (vs. non-users) had greater odds of reporting likelihood to use LAI (AOR = 3.29, 95% CI = 2.12 to 5.11), whereas men reporting recent unprotected anal sex had a greater odds of likelihood to use a penile gel (AOR = 1.79, 95% CI = 1.27 to 2.52) and an anal suppository (AOR = 1.48, 95% CI = 1.08 to 2.02). Hispanic/Latino (vs. White) MSM (AOR = 2.29, 95% CI = 1.40 to 3.73) and, marginally, Black MSM (AOR = 1.54, 95% CI = 1.00 to 2.38) had greater odds of reporting likelihood to use penile gel. Similar patterns were found for rank ordering preference of products, including condoms. CONCLUSIONS: Most MSM were interested in using various potential future HIV prevention products, especially LAI. However, two typologies of potential users emerged: men who prefer sexual event-based methods (condoms, event-based pill, sexual gels and suppositories) and men who prefer non-sexual event-based methods (daily pill, LAI). Men who reported recent unprotected anal sex preferred a penile gel product most, followed closely by sexual event-based pills and LAI. Racial/ethnic differences were noted as well. These findings on product preferences can help in formulation development and messaging.

This cross-sectional study used data from the M-Cubed randomized clinical trial to assess the prevalence of pre-exposure prophylaxis (PrEP) medication sharing among HIV-negative men who have sex with men.

In an era of effective1 and increasingly accessible2 daily oral HIV pre-exposure prophylaxis (PrEP) in the United States, the understanding of sexual risk and protected behavior among men who have sex with men (MSM) is changing.3 Before PrEP, condoms were the only primary HIV prevention product available; sexual risk was defined as lack of condom use during anal sex, with encounter-specific behavior being most useful for understanding contextual risk (eg, substance use).4 Furthermore, decades of research have documented evidence of associations between substance use and condomless sex among MSM,4–7 with only sex-linked methamphetamine (stimulant) and binge alcohol use consistently associated with condomless anal sex in a prior review of the literature on sexual event-level substance use and HIV risk behavior.4 This association of risk is generally thought of as a direct relation between cognitive-behavioral state of substance-using sex (for some substances), and risk because of impaired judgement, limited physical coordination, competing emotional priorities, and other contextual explanations in the “hot” moment of a sexual encounter.8 As use of daily PrEP increases in MSM populations,2 a more complex assessment is possible and needed to measure “protected” and “unprotected” sex through use of 2 recommended primary HIV prevention products, condoms and daily PrEP.3 Advanced measurement and analyses may provide better understanding of the nature of the relationship between substance use and daily PrEP, a prevention method typically taken in “cold” moments outside of the sexual encounter,8 as well as the “hot” moment for condom use.8 Herein, we present analyses that address (1) condom and/or PrEP use as protected sex, and (2) the association of sexual event-level substance use with condom and/or PrEP use.

BACKGROUND: Men who have sex with men (MSM) continue to be the predominately impacted risk group in the United States HIV epidemic and are a priority group for risk reduction in national strategic goals for HIV prevention. Modeling studies have demonstrated that a comprehensive package of status-tailored HIV prevention and care interventions have the potential to substantially reduce new infections among MSM. However, uptake of basic prevention services, including HIV testing, sexually transmitted infection (STI) testing, condom distribution, condom-compatible lubricant distribution, and preexposure prophylaxis (PrEP), is suboptimal. Further, stronger public health strategies are needed to promote engagement in HIV care and viral load suppression among MSM living with HIV. Mobile health (mHealth) tools can help inform and encourage MSM regarding HIV prevention, care, and treatment, especially among men who lack access to conventional medical services. This protocol details the design and procedures of a randomized controlled trial (RCT) of a novel mHealth intervention that comprises a comprehensive HIV prevention app and brief, tailored text- and video-based messages that are systematically presented to participants based on the participants' HIV status and level of HIV acquisition risk. OBJECTIVE: The objective of the RCT was to test the efficacy of the Mobile Messaging for Men (M-Cubed, or M3) app among at least 1200 MSM in Atlanta, Detroit, and New York. The goal was to determine its ability to increase HIV testing (HIV-negative men), STI testing (all men), condom use for anal sex (all men), evaluation for PrEP eligibility, uptake of PrEP (higher risk HIV-negative men), engagement in HIV care (men living with HIV), and uptake of and adherence to antiretroviral medications (men living with HIV). A unique benefit of this approach is the HIV serostatus-inclusiveness of the intervention, which includes both HIV-negative and HIV-positive MSM. METHODS: MSM were recruited through online and venue-based approaches in Atlanta, Detroit, and New York City. Men who were eligible and consented were randomized to the intervention (immediate access to the M3 app for a period of three months) or to the waitlist-control (delayed access) group. Outcomes were evaluated immediately postintervention or control period, and again three and six months after the intervention period. Main outcomes will be reported as period prevalence ratios or hazards, depending on the outcome. Where appropriate, serostatus/risk-specific outcomes will be evaluated in relevant subgroups. Men randomized to the control condition were offered the opportunity to use (and evaluate) the M3 app for a three-month period after the final RCT outcome assessment. RESULTS: M3 enrollment began in January 2018 and concluded in November 2018. A total of 1229 MSM were enrolled. Data collection was completed in September 2019. CONCLUSIONS: This RCT of the M3 mobile app seeks to determine the effects of an HIV serostatus-inclusive intervention on the use of multiple HIV prevention and care-related outcomes among MSM. A strength of the design is that it incorporates a large sample and broad range of MSM with differing prevention needs in three cities with high prevalence of HIV among MSM.

ABSTRACTOutbreaks of emerging infectious disease are a constant threat. In the last 10 years, there have been outbreaks of 2009 influenza A (H1N1), Ebola virus disease, and Zika virus. Stigma associated with infectious disease can be a barrier to adopting healthy behaviors, leading to more severe health problems, ongoing disease transmission, and difficulty controlling infectious disease outbreaks. Much has been learned about infectious disease and stigma in the context of nearly 4 decades of the human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome pandemic. In this paper, we define stigma, discuss its relevance to infectious disease outbreaks, including how individuals and communities can be affected. Adapting lessons learned from the rich literature on HIV-related stigma, we propose a strategy for reducing stigma during infectious disease outbreaks such as Ebola virus disease and Zika virus. The implementation of brief, practical strategies such as the ones proposed here might help reduce stigma and facilitate more effective control of emerging infectious diseases.

Men who have sex with men (MSM) continue to be the group at highest risk for HIV infection in the United States, and Hispanic/Latino MSM are at disproportionate risk for HIV infection compared with white MSM [1]. Furthermore, the estimated annual percentage change in the United States from 2008 to 2015 increased for Hispanic/Latino MSM, whereas it decreased for white MSM [2]. | | Pre-exposure prophylaxis (PrEP) is an efficacious tool for preventing the acquisition of HIV [3]. The Centers for Disease Control and Prevention clinical guidelines and recommendations for PrEP use have been available since 2014 and were updated in 2017 [4]. Yet, PrEP awareness and uptake are still lacking among Hispanic/Latino MSM [5]. A recent study of young MSM in Atlanta, Chicago, and New York City found awareness of PrEP to be lower among Latino/Hispanic compared with whites [6].

We examined HIV conspiracy beliefs and PrEP awareness in a convenience sample of minority MSM. Participants in three cities completed a behavioral self-assessment on sociodemographics, PrEP awareness, and HIV/AIDS conspiracy beliefs. HIV/AIDS conspiracy beliefs were more common among Black than Latino MSM (58% vs. 42%, p < .05), and among younger men than older men (age 18-29 (50%), 30-39 (22%), 40+ (28%); p < .05). PrEP awareness co-occurred with conspiracy belief less (37%) than with non-belief (63%, p < .05), persisting in multivariable regression (aOR = 0.52, 95% CI = 0.38-0.71). This relationship suggests that current HIV care and prevention messaging is either inaccessible or not credible to some minority subpopulations.

BACKGROUND: HIV pre-exposure prophylaxis (PrEP) is efficacious, however many MSM (especially racial/ethnic minorities) are still unaware of and under-utilize it. METHODS: The 2014 Messages4Men Study focuses on black and Hispanic/Latino MSM in Chicago, Fort Lauderdale, and Kansas City (n=937). Brief (2-3 sentence) messages were tested: a PrEP message tailored for HIV-uninfected MSM (n=607) and a PrEP message tailored for HIV-infected MSM (n=330). After reading the message, participants reported believability and awareness, and intent to use PrEP and condoms. Analyses consisted of bivariate and multivariable approaches. RESULTS: Among HIV-uninfected MSM, black (vs. Hispanic/Latino) MSM indicated greater intentions to use PrEP (81% vs. 70% respectively, p<.05); 72% overall had similar intentions to use condoms after hearing a PrEP message. PrEP information was new (63%) and believable (80%), with no racial/ethnic differences (p>.05). In multivariable analysis, men who reported recent condomless anal sex were less likely to report the PrEP message enhanced their intent to use condoms in the future. DISCUSSION: Several years into the availability of PrEP, black and Hispanic/Latino MSM continue to be unaware of PrEP and its benefits, although information is largely believable once provided. The HIV prevention field should be prepared to incorporate new information about HIV prevention options into brief messages delivered through technology and social media.

Gay, bisexual, and other men who have sex with men (MSM) are disproportionately affected by HIV. MSM comprise roughly 2% of the US population, yet approximately two-thirds of new HIV infections are among MSM (Centers for Disease Control and Prevention, 2016). Additionally, significant racial and ethnic disparities exist with respect to HIV transmission among MSM. Based on the current HIV diagnoses rates in the US, about 1 in 2 African American men who have sex with men (AAMSM), 1 in 4 Latino MSM (LMSM) and 1 in 11 white MSM will be diagnosed with HIV during their lifetime (Center for Disease Control and Prevention (CDC), 2016a). In general, substance-using MSM are among the groups with the greatest risk for HIV infection (Centers for Disease Control and Prevention, 2011; Margolis, Joseph, Hirshfield, et al., 2014; Pines, Gorbach, Weiss, et al., 2014; Plankey, Ostrow, Stall, et al., 2007); nearly a third of incident HIV infections among MSM may be associated with non-injection drug use (Mansergh et al., 2008; Van Tieu & Koblin, 2009). Substance-using sexual minorities are more likely to underutilize substance use treatment (McCabe, Bostwick, Hughes, West, & Boyd, 2010) and may be an HIV transmission bridge to non-drug-using populations (Lambert et al., 2011). | With respect to alcohol use, high rates of both alcohol consumption and binge drinking have been documented among MSM populations (Finlayson et al., 2011). Additionally, previous studies have found associations between heavy drinking, as define as having 6 or more drinks on one occasion or 4 or more drinks daily, and HIV risk behaviors among MSM, such as condomless anal intercourse and greater number of sexual patterns (Colfax et al., 2004; Greenwood et al., 2001; Koblin et al., 2003a; Woolf & Maisto, 2009). Previous studies also suggest that many substance-using MSM populations engage in use of multiple substances, often concomitantly (Santos et al., 2013). There also may be a dose response with number and frequency of substances used with respect to condomless anal sex among HIV negative MSM (Santos et al., 2013). However, patterns of substance-use vary across racial and ethnic MSM populations, e.g. African American substance-using MSM being more likely to use crack/cocaine relative to other substance-using MSM populations (Goldstein, Burstyn, LeVasseur, & Welles, 2016; Halkitis & Jerome, 2008; Hatfield, Horvath, Jacoby, & Simon Rosser, 2009; Mimiaga, Reisner, Fontaine, et al., 2010; Paul, Boylan, Gregorich, Ayala, & Choi, 2014). Thus, it is important to better understand patterns of concomitant substance-use, e.g. methamphetamine, crack/cocaine and alcohol, across specific sociodemographic categories among MSM populations (Santos et al., 2013). Sociodemographic characteristics which may be particularly relevant for specific MSM populations include poverty and history of incarceration. For example, pronounced racial disparities have been found between AAMSM and other MSM populations with respect to structural barriers, such as low income, unemployment and incarceration, associated with HIV infection (Millet, Peterson, Flores, Hart, et al., 2012). Additionally, a recent study conducted by Rutledge et al, found a high proportion of MSM reporting both a history of incarceration and substance use. This study found rates of incarceration highest among men who classified themselves as “down-low”, e.g. endorsing secrecy about same-sex sexual behavior, promting the authors to posit that this population may engage in trading sex for money more often and thus increase their risk for incarceration (Rutledge, Jemmott, O'Leary, & Icard, 2016).

BACKGROUND: Men who have sex with men (MSM) have a relatively high prevalence of sexually transmitted infections (STIs). This study examines the association of self-reported STIs and use of mobile phones and/or computer-based Internet to meet sexual partners among black and Hispanic/Latino MSM in the United States. METHODS: Black and Hispanic/Latino MSM (N = 853) were recruited from 3 US cities (Chicago, IL; Kansas City, MO; and Fort Lauderdale, FL) via online and community outreach. Men completed a computer-assisted, self-interview assessment on demographics, use of mobile phones and computer-based Internet for sex-seeking, sexual risk behavior, and self-reported bacterial STIs in the past year. Multivariable logistic regression was used to model independent associations of STIs and use of these technologies to meet sexual partners. RESULTS: Twenty-three percent of the sample reported having an STI in the past year; 29% reported using a mobile phone and 28% a computer-based Internet mostly for sex-seeking; and 22% reported using both. Number of male sexual partners (past year) was associated with any STI (adjusted odds ratio, 1.03; 95% confidence interval, 1.01-1.06). Adjusting for human immunodeficiency virus status, number of male sexual partners (past year), and demographic variables, men who reported use of both mobile phones and computer-based Internet for sex-seeking had increased odds of reporting an STI (adjusted odds ratio, 2.59; 95% confidence interval, 1.75-3.83), as well as with separate reports of chlamydia, gonorrhea, and syphilis (P's < 0.05). CONCLUSIONS: Enhanced community education regarding STI prevention, testing, and treatment options are necessary among this subpopulation of MSM who may benefit from messaging via Internet and mobile phone application sites.

This pilot study examined effects of HIV prevention messages about self and partner benefits of antiretroviral therapy (ART) and condom effectiveness on increased intentions for behavior change. Data were from Messages4Men, a study examining prevention messages among 320 HIV-positive and 605 HIV-negative black and Latino MSM. Men completed a computer-based assessment after message exposure, and multivariable models controlled for risky sex and demographics. A majority of HIV-positive men reported increased intentions for ART use; 22% reported partner benefit information was new. HIV-positive men with a detectable viral load had significantly greater adjusted odds of reporting intentions for ART use. Over half of HIV-negative MSM reported ART benefit information was new, and 88% reported increased intentions to discuss ART use with infected partners. Black MSM anticipated they would increase condom use in response to the self and partner benefit messages. Tailored messages on benefits of ART are needed for MSM.

Men who have sex with men (MSM) of color are disproportionately affected by HIV in the United States. Pre-exposure prophylaxis (PrEP) using antiretroviral medications is a newer biomedical prevention modality with established efficacy for reducing the risk of acquiring HIV. We conducted formative qualitative research to explore audience reactions and receptivity to message concepts on PrEP as part of the development of prevention messages to promote PrEP awareness among black and Latino MSM in the United States. In 2013, 48 black and 42 Latino (total study sample = 90) mixed HIV serostatus MSM from Chicago, Ft. Lauderdale, and Kansas City participated in either an individual interview or focus group discussion. Men were recruited online and at community-based organizations in each city. We elicited feedback on the comprehensibility, credibility, and relevance of two draft messages on PrEP. The messages included efficacy estimates from iPrEx, a phase III clinical trial to ascertain whether the antiretroviral medication tenofovir/emtricitabine disoproxil fumarate (commercially known as Truvada(R)) could safely and effectively prevent HIV acquisition through sex among MSM and transgender women. With participants' consent, the interviews and focus groups were recorded and transcribed. The data were then summarized and analyzed using a qualitative descriptive approach. The majority of men were unfamiliar with PrEP. It was suggested that additional information about the medication and clinical trials establishing efficacy was needed to enhance the legitimacy and relevancy of the messages. Participants sought to form an opinion of PrEP that was grounded in their own interpretation of the efficacy data. However, confusion about nonadherence among clinical trial subjects and individual versus average risk limited comprehension of these messages. Thematic overlaps suggest that message believability was connected to participants' ability to derive meaning from the PrEP efficacy data. Despite being concerned that other MSM would interpret the messages to mean that condom use was unnecessary while taking PrEP, participants themselves primarily understood PrEP as a supplement rather than a replacement for condoms. Based on their experience with taking antiretroviral medication, HIV-positive men considered condom use a more feasible form of HIV prevention than PrEP. Participants' responses suggest that more information about PrEP and the clinical trial would support the legitimacy of PrEP and the messages as a whole. These details may enhance believability in the concept of PrEP and reinforce confidence in the validity of the efficacy result.

We examined intent to get tested for HIV infection and use condoms among n = 604 uninfected black and Latino men who have sex with men after receiving brief information messaging that 1 in 10 minority men who have sex with men had HIV infection and did not know it. Information awareness, newness, believability, HIV testing cost willingness, and associated demographic variables were also assessed.

Men who have sex with men (MSM) in the United States continue to be disproportionately affected by HIV, particularly those who are younger and African American/black and Latino MSM.1 Antiretroviral preexposure prophylaxis (PrEP) is an efficacious biomedical intervention for reducing HIV acquisition. An international study of MSM found PrEP efficacy levels to be 44% for the sample overall, 73% among men with good self-reported adherence, and 95% among men in which PrEP medication was detected in their blood.2 Although awareness of and access to PrEP is a concern,3 it is an additional option for reducing risk of HIV infection. This is particularly helpful since a recent study found only 70% effectiveness for condom use during anal sex among MSM.4 However, there are concerns about potential “risk compensation,” wherein a large shift occurs from condom use to PrEP use, potentially resulting in little practical net benefit (or even net loss) in protection from HIV infection with less than good adherence to PrEP.5 As information about PrEP continues to reach populations that could benefit from its use, prevention practitioners must understand the potential for PrEP uptake and risk compensation. | We analyzed data on behavioral intentions to use condoms, PrEP, or both methods among HIV-uninfected black and Latino MSM in the United States. Data are from Messages4Men, a 2014 cross-sectional study conducted to better understand preferences for new HIV prevention information and methods among black and Latino MSM in Chicago, Fort Lauderdale, and Kansas City. This analysis included HIV-uninfected (self-reported) black (n = 296) and Latino (n = 309) men who reported having sex with a man in the past year, recruited through online, agency, and street/venue outreach efforts. Demographic variables and anal sex without a condom in the previous 3 months were reported through computer assessment. After informing participants that a daily pill exists to prevent HIV infection (ie, PrEP) that was found to be 73% efficacious with good adherence2 and that condoms have been found to be 70% effective for anal use among MSM,4 participants were asked: If you had a choice of using condoms during anal sex or taking a pill every day to prevent HIV infection at no cost to you, which would you pick? Response options included condoms, PrEP, or both methods.

Men who have sex with men (MSM) are still disproportionately affected by HIV/AIDS in the United States. While gay, bisexual, and other MSM represent an estimated 2% of the US population,1 as of 2010, this population accounted for approximately 56% of those living with HIV and 63% of new HIV infections.2 Studies of a syndemic association of multiple physical and mental health factors (eg, depression, substance use or abuse, childhood sexual abuse, experienced gay, or bisexual stigma) among MSM have found those factors to be associated with each other and with risk for HIV transmission.3,4 There are mixed research findings regarding the specific association of depression and unprotected anal sex (ie, without a condom), with supporting evidence found in some studies5 but not others.6,7 Recent studies that tend to support an association of depression and sexual risk among MSM5,8 have applied broad definitions of behavior and not stratified analyses by HIV serostatus or specific sexual risk behaviors. For example, Reisner et al8 assessed a combined variable of all unprotected sex (anal and/or vaginal) for both men and women, whereas Fendrich et al5 reported unprotected receptive and insertive anal sex separately but not stratified by HIV serostatus before calculating odds ratios. Stratified analysis for specific behaviors is critical in understanding nuanced associations for the highest risk behaviors for HIV acquisition/transmission by HIV serostatus (ie, unprotected receptive anal sex for HIV-negative MSM; unprotected insertive anal sex for HIV-positive MSM). This study examines the association of depressive symptoms and unprotected insertive and receptive anal sex, separately and by HIV serostatus, among substance-using MSM who reported recent unprotected sexual behavior. | A convenience sample of HIV-negative and HIV-positive MSM (n = 1203) who reported unprotected anal sex and substance use during anal sex in the previous 6 months was enrolled in the Project MIX trial in Chicago, Los Angeles, NY City, and San Francisco. The purpose of the trial was to test a behavioral intervention to reduce sexual risk behavior of substance-using MSM; study methods and results are discussed in detail elsewhere.9 CDC and local Institutional Review Boards in each city approved the study protocol. Participants completed a baseline assessment in 2005–2006 that measured self-reported demographic variables, HIV status (including only men first diagnosed as HIV positive >6 months before study enrollment), recent unprotected anal sex (UA, ie, without a condom in the past 3 months) with a nonprimary male partner [including unprotected receptive (URA) and insertive (UIA)], drug use during the sexual encounter, depressive symptoms, and other psychosocial variables. Depressive symptoms in the past week were measured using 7 items from Santor and Coyne's 9-item short version of the Center for Epidemiological Studies—Depression (CES-D) scale, Cronbach alpha = 0.87.10 Two items were dropped due to low interitem correlations, as done earlier.11 A mean overall score for each participant was dichotomized to indicate depressive symptoms occurred “never” or “sometimes” (1–2) or “more than sometimes” (>2 to 4) in the past week.

Fifty-two non-treatment-seeking methamphetamine-using men who have sex with men were enrolled in Project Tech Support, an open-label pilot study to evaluate whether exposure to theory-based [social support theory (SST), social cognitive theory (SCT), and health belief model (HBM)] text messages could promote reductions in HIV sexual risk behaviors and/or methamphetamine use. Multivariable analyses revealed that increased relative exposure to HBM or SCT (vs. SST) text messages was associated with significant reductions in the number of HIV serodiscordant unprotected (i.e., without a condom) anal sex partners, engagement in sex for money and/or drugs, and frequency of recent methamphetamine use; additionally, increased relative exposure to HBM (vs. SCT or SST) messages was uniquely associated with reductions in the overall number of non-primary anal sex partners (all p ≤ 0.05, two-tailed). Pilot data demonstrated that text messages based on the principles of HBM and SCT reduced sentinel HIV risk and drug use behaviors in active methamphetamine users.

OBJECTIVES: There is a continuing need to identify factors associated with risk for HIV transmission among men who have sex with men (MSM), including a need for further research in the ongoing scientific debate about the association of internalised homophobia and sexual risk due partly to the lack of specificity in analysis. We assess the association of internalised homophobia by race/ethnicity within HIV serostatus for a large sample of substance-using MSM at high risk of HIV acquisition or transmission. METHODS: Convenience sample of substance-using (non-injection) MSM reporting unprotected anal sex in the prior 6 months residing in Chicago, Los Angeles, New York and San Francisco. The analytic sample included HIV-negative and HIV-positive black (n=391), Latino (n=220), and white (n=458) MSM. Internalised homophobia was assessed using a published four-item scale focusing on negative self-perceptions and feelings of their own sexual behaviour with men, or for being gay or bisexual. Analyses tested associations of internalised homophobia with recent risk behaviour, stratified by laboratory-confirmed HIV serostatus within race/ethnicity, and controlling for other demographic variables. RESULTS: In multivariate analysis, internalised homophobia was inversely associated (p<0.05) with recent unprotected anal sex among black MSM, and not significantly associated with sexual risk behaviour among white and Latino MSM. CONCLUSIONS: More research is needed to further identify nuanced differences in subpopulations of MSM, but these results suggest differentially targeted intervention messages for MSM by race/ethnicity.

Compared with the extant research on heterosexual intimate partner violence (IPV)-including the knowledge base on alcohol and illicit drug use as predictors of such IPV-there is a paucity of studies on IPV among men who have sex with men (MSM), especially Black MSM. This study investigates the prevalence of experiencing and perpetrating IPV among a sample of Black MSM couples and examines whether heavy drinking and/or illicit substance use is associated with IPV. We conducted a secondary analysis on a data set from 74 individuals (constituting 37 Black MSM couples) screened for inclusion in a couple-based HIV prevention pilot study targeting methamphetamine-involved couples. More than one third (n= 28, 38%) reported IPV at some point with the current partner: 24 both experiencing and perpetrating, 2 experiencing only, and 2 perpetrating only. IPV in the past 30 days was reported by 21 (28%) of the participants: 18 both experiencing and perpetrating, 1 experiencing only, and 2 perpetrating only. Heavy drinking and methamphetamine use each was associated significantly with experiencing and perpetrating IPV throughout the relationship as well as in the past 30 days. Rock/crack cocaine use was significantly associated with any history of experiencing and perpetrating IPV. Altogether, IPV rates in this sample of Black MSM couples equal or exceed those observed among women victimized by male partners as well as the general population of MSM. This exploratory study points to a critical need for further efforts to understand and address IPV among Black MSM. Similar to heterosexual IPV, results point to alcohol and illicit drug use treatment as important avenues to improve the health and social well-being of Black MSM.

The role men who have sex with men and women (MSMW) play in heterosexual HIV transmission is not well understood. We analyzed baseline data from Project MIX, a behavioral intervention study of substance-using men who have sex with men (MSM), and identified correlates of unprotected vaginal intercourse, anal intercourse, or both with women (UVAI). Approximately 10% (n=194) of the men reported vaginal sex, anal sex, or both with a woman; of these substance-using MSMW, 66% (129) reported UVAI. Among substance-using MSMW, multivariate analyses found unemployment relative to full/part-time employment (OR=2.28; 95% CI 1.01, 5.17), having a primary female partner relative to no primary female partner (OR=3.44; CI 1.4, 8.46), and higher levels of treatment optimism (OR=1.73; 95% CI 1.18, 2.54) increased odds of UVAI. Strong feelings of connection to a same-race gay community (OR=0.71; 95% CI 0.56, 0.91) and Viagra use (OR=0.31; 95% CI 0.10, 0.95) decreased odds of UVAI. This work suggests that although the proportion of substance-using MSM who also have sex with women is low, these men engage in unprotected sex with women, particularly with primary female partners. This work highlights the need for further research with the substance using MSMW population to inform HIV prevention interventions specifically for MSMW.
