High Human Immunodeficiency Virus Incidence and Prevalence and Associated Factors Among Adolescent Sexual Minority Males-3 Cities, 2015

Point-of-care urine tenofovir test predicts future HIV preexposure prophylaxis discontinuation among young users

BACKGROUND

Young men who have sex with men and transgender women (YMSM/TGW) have disproportionately high HIV incidence and lower preexposure prophylaxis (PrEP) adherence. Point-of-care (POC) urine tenofovir (TFV) rapid assay (UTRA) testing permits real-time monitoring for nonadherence within clinical settings. We performed UTRA testing among PrEP users to examine the relationship between low PrEP adherence and future PrEP discontinuation, and the accuracy of POC testing compared to gold-standard liquid chromatography tandem mass spectrometry (LC/MS/MS).

METHODS

YMSM/TGW participants ( n  = 100) were recruited during a daily PrEP visit. Logistic regression models analyzed the relationship between the primary predictor of urine POC assay results (cutoff 1,500 ng/ml) and the primary outcome of PrEP discontinuation, defined as no PrEP follow-up or prescription within 120 days.

RESULTS

Overall, 19% of participants had low urine TFV and 21% discontinued PrEP, while 11% of participants self-reported low PrEP adherence (<4 pills per week), which was only 43% sensitive/84% specific in predicting low TFV levels and was not associated with PrEP discontinuation. Low urine TFV level predicted PrEP discontinuation [adjusted odds ratio (AOR) 6.1; 95% confidence interval (CI): 1.4-11; P  = 0.005] and was 71% sensitive/90% specific for discontinuation after 120 days. Compared to LC/MS/MS, UTRA testing had a 98% positive and 100% negative predictive value.

CONCLUSIONS

In a sample of YMSM/TGW on daily PrEP, POC UTRA testing predicted PrEP discontinuation more accurately than self-reported adherence, with high predictive values compared to LC/MS/MS. UTRA testing may be a clinical tool for directing preventive interventions towards those likelier to discontinue PrEP despite ongoing HIV vulnerability.

"Your Package Could Not Be Delivered": The State of Digital HIV Intervention Implementation in the US

PURPOSE OF REVIEW

Despite continuous innovations and federal investment to create digital interventions addressing the HIV prevention and care continua, these interventions have not reached people in the U.S. at scale. This article reviews what is known about U.S. implementation of digital HIV interventions and presents a strategy to cross the research-to-practice chasm for these types of interventions.

RECENT FINDINGS

We conducted a narrative review of U.S.-based original research on implementation of digital HIV interventions and identified few studies reporting on implementation determinants, strategies, processes, or outcomes, particularly outside the context of effectiveness trials. To supplement the literature, in 2023, we surveyed 47 investigators representing 64 unique interventions about their experiences with implementation after their research trials. Respondents placed high importance on intervention implementation, but major barriers included lack of funding and clear implementation models, technology costs, and difficulty identifying partners equipped to deliver digital interventions. They felt that responsibility for implementation should be shared between intervention developers, deliverers (e.g., clinics), and a government entity. If an implementation center were to exist, most respondents wanted to be available for guidance or technical assistance but largely wanted less involvement. Numerous evidence-based, effective digital interventions exist to address HIV prevention and care. However, they remain "on the shelf" absent a concrete and sustainable model for real-world dissemination and implementation. Based on our findings, we call for the creation of national implementation centers, analogous to those in other health systems, to facilitate digital HIV intervention delivery and accelerate progress toward ending the U.S. epidemic.

Enhancing routine HIV and STI testing among young men who have sex with men: primary outcomes of the get connected clinical randomized trial (ATN 139)

BACKGROUND

Regular HIV and STI testing remain a cornerstone of comprehensive sexual health care. In this study, we examine the efficacy of Get Connected, a WebApp that combines test locators with personalized educational resources, in motivating young men who have sex with men (YMSM) to undergo regular HIV and STI testing.

METHODS

Participants were randomly placed in one of two conditions. The first condition included the full version of GC (GC-PLUS), which included content tailored to users' psychosocial characteristics (e.g., age, race/ethnicity, relationship status, HIV/STI testing history). The second condition served as our attention-control and only included the testing locator (GC-TLO) for HIV/STI testing services. Participants were recruited from three cities (Houston, Philadelphia, and Atlanta) characterized by high HIV incidence. Assessments were collected at 1, 3-, 6-, 9- and 12-month follow-ups.

RESULTS

Both versions of GC were acceptable and efficacious in increasing routine HIV and STI testing over a 12-month period. 40% of the sample reported testing at least twice, with no main effects observed across the two intervention arms (OR = 1.11; 95% CI: 0.69, 1.80), p =.66). Greater intervention effects were observed among YMSM who engaged more frequently with the intervention, with regional differences observed.

CONCLUSIONS

Our findings underscore the need to cater to the diverse needs of YMSM through multilevel approaches. Broadly, mHealth HIV/STI testing interventions, such as Get Connected, would benefit from matching technologies to the local context to have the greatest impact.

A Systematic Review of Implementation Research on Determinants and Strategies of Effective HIV Interventions for Men Who Have Sex with Men in the United States

Men who have sex with men (MSM) are disproportionately affected by HIV, accounting for two-thirds of HIV cases in the United States despite representing ∼5% of the adult population. Delivery and use of existing and highly effective HIV prevention and treatment strategies remain suboptimal among MSM. To summarize the state of the science, we systematically review implementation determinants and strategies of HIV-related health interventions using implementation science frameworks. Research on implementation barriers has focused predominantly on characteristics of individual recipients (e.g., ethnicity, age, drug use) and less so on deliverers (e.g., nurses, physicians), with little focus on system-level factors. Similarly, most strategies target recipients to influence their uptake and adherence, rather than improving and supporting implementation systems. HIV implementation research is burgeoning; future research is needed to broaden the examination of barriers at the provider and system levels, as well as expand knowledge on how to match strategies to barriers-particularly to address stigma. Collaboration and coordination among federal, state, and local public health agencies; community-based organizations; health care providers; and scientists are important for successful implementation of HIV-related health innovations.

Potential contribution of PrEP uptake by adolescents 15-17 years old to achieving the "Ending the HIV Epidemic" incidence reduction goals in the US South

BACKGROUND

The "Ending the HIV Epidemic" (EHE) initiative seeks to reduce new HIV infections in the U.S. by prioritizing federal resources towards highly impacted populations. Antiretroviral therapy (ART) and pre-exposure prophylaxis (PrEP) are essential for reaching EHE goals. Adolescents are often at increased risk for HIV because they may lack agency in negotiating their sexual partnerships and may not have the same access to treatment and prevention as adults. This study estimates the potential contribution of expanded PrEP coverage among adolescents ages 15-17 to achieving the EHE goals in the South.

METHODS

An HIV-transmission model was built to simulate the HIV epidemic in the South. Increased ART and PrEP uptake were systematically varied with and without PrEP eligibility including individuals age<18.

RESULTS

Prioritizing PrEP for adolescents had a negligible impact on incidence. At 50% uptake among eligible adolescents and 90% ART coverage, including adolescents only improved the percentage of infections averted from 80.1% to 80.3%. In 10 of 15 scenarios explored, there was no reduction in new infections when PrEP eligibility was expanded to include adolescents age<18. At 95% ART coverage at the population-level incidence among adolescents declined by over 80%, but PrEP uptake among adolescents did not contribute to additional declines in incidence among adolescents.

CONCLUSIONS

Prioritizing PrEP for adolescents did not significantly contribute to reaching EHE incidence reductions goal. Focusing resources to specific adolescent populations at risk, such sexual minority males in high incidence settings, will remain an important public health goal outside the context of EHE.

A global systematic scoping review of literature on the sexual exploitation of boys

BACKGROUND

Sexual exploitation of children (SEC) is a widespread crime which impacts the child victim across developmental, health and well-being domains. As victims, boys have received much less clinical and research attention. While context-specific factors likely shape the SEC risk, under-recognized gender norms can deny boys' vulnerability. Professional failures to recognize and respond adequately to boys' sexual exploitation may prevent access to support.

OBJECTIVE

This systematic scoping review updates and broadens a previous review of literature addressing prevalence, victim/offender/facilitator characteristics, control mechanisms, as well as the health correlates and outcomes regarding sexual exploitation of boys. This review included international peer-reviewed and gray literature from 38 countries in 14 languages.

PARTICIPANTS AND SETTING

Studies from the years 2000 to 2022 that included samples of boys under age 18, or sex-disaggregated data for children under 18, were included. Case studies, systematic reviews, and those reporting on retrospective experiences by adults over 18 were excluded. A total of 254,744 boys were represented across 81 studies.

METHODS

A systematic scoping review considered qualitative and quantitative peer-reviewed publications from eight, English-language databases. English and non-English non-peer reviewed publications ('gray literature') was identified by both ECPAT International's global network of member organizations and citation chaining.

RESULTS

Overall, 81 peer-reviewed (n = 51) and gray literature (n = 30) documents from 38 countries were included. In total, 254,744 youth participated in peer-reviewed studies (N = 217,726) and gray literature (N = 37,018). General prevalence of sexual exploitation of boys was reported at up to 5 %, with higher rates noted in specifically vulnerable sub-populations (e.g., 10 %, trans youth; 26 %, street-connected youth). The literature indicates that sexual exploitation of boys is reported as occurring primarily between 12 and 18 years old. Multi-level factors are linked to SEC, including individual (e.g., disability status), relationship (e.g., child maltreatment, dating violence), community (e.g., community violence), and societal domains (e.g., discriminatory beliefs). SEC victimization is linked with youth mental and physical health concerns, particularly sexual health. Post-traumatic stress symptomatology or disorder was rarely evaluated. Evidence-based treatments were not available, which may be related to a lack of gender-based theoretical models for understanding SEC specifically.

CONCLUSION

The sexual exploitation of boys is a prevalent public health, child rights, and clinical issue. All young people experiencing sexual exploitation face sex- and gender-specific challenges, and this remains the case for boys with indications including family rejection, implicit community tolerance for abuse to service accessibility barriers. Actioning our duty to care for all children requires gender- and trauma-informed lenses. Ongoing surveillance of all forms of violence against children, with gender disaggregation, is essential for practice and policy advancement.

AIDS or HIV Education and Sexual Behaviors Among Adolescent Sexual Minority Males: National HIV Behavioral Surveillance, 3 U.S. Cities, 2015

In the U.S., HIV transmission rates have increased among male-male sexual contacts. Sex education reduces HIV-related risks; yet impacts for adolescent sexual minority males (ASMM) are less known. Data from a sample (n = 556) of ASMM (aged 13-18) in three U.S cities were used to examined associations between HIV education in school and sexual behaviors. Outcomes of interest included: sexually transmitted infection (STI), multiple sex partners, and condomless anal intercourse (CAI) with a male (all past 12 months). Adjusted prevalence ratios (aPR) and 95% confidence intervals (CI) were calculated. Of 556 ASMM, 84% reported received HIV education. Among sexually active ASMM (n = 440) who received HIV education, fewer reported an STI (10% vs. 21%, aPR: 0.45, CI [0.26, 0.76]) and CAI (48% vs. 64%, aPR: 0.71, CI [0.58, 0.87]) than ASMM who did not receive HIV education. Protective effects of school HIV education on sexual behaviors are promising and suggest prevention education is vital to reducing HIV- and STI-related risks among ASMM.

Prevalence of Mollicutes among men who have sex with men and transgender women aged 15 to 19 years in Salvador, North-eastern Brazil

BACKGROUND

Some species of Mollicutes have been associated with different pathologies of the urogenital tract in humans, with a high prevalence among adult men who have sex with men (MSM) and transgender women (TGW). However, few studies have been performed to investigate its prevalence among adolescents. In this study, we estimated the initial prevalence of Mycoplasma genitalium (MG), Mycoplasma hominis (MH), Ureaplasma urealyticum (UU), and Ureaplasma parvum (UP); the rate of misdiagnosis at different anatomical sites; and the associated factors with positive tests for Mollicutes among MSM and TGW aged 15 to 19 years enrolled in the PrEP1519 study.

METHODS

PrEP-1519 is the first study to investigate the effectiveness of pre-exposure prophylaxis for human immunodeficiency virus among adolescent MSM and TGW aged 15 to 19 in Latin America. Oral, anal, and urethral swabs were taken from 246 adolescents upon enrolment in the study to detect MG, MH, UU, and UP by quantitative polymerase chain reaction (qPCR). Bivariate and multivariate analyses were conducted by Poisson regression and 95% confidence intervals (95% CI) were estimated.

RESULTS

The prevalence of Mollicutes was 32.1%. UU was the most prevalent species (20.7%), followed by MH (13.4%), MG (5.7%), and UP (3.2%); 67.3% of the positive samples would have been missed if only urethral samples had been taken. Receptive anal sex (prevalence ratio [PR] = 1.79; 95% CI = 1.07-3.01) and clinical suspicion of sexually transmitted infection (PR = 1.62; 95% CI = 1.01-2.61) were factors associated with the detection of Mollicutes in general. Group sex (PR = 1.98; 95% CI = 1.12-3.50) and receptive anal sex (PR = 2.36; 95% CI = 0.95-5.86) were associated with the detection of Mycoplasma spp. No sociodemographic, clinical, or behavioural variable was significantly associated with the detection of Ureaplasma spp.

CONCLUSIONS

A high prevalence of Mollicutes was observed among adolescent MSM and TGW, especially at extragenital sites. Further research is required to understand the epidemiological profile of high-risk adolescents in different regions and contexts, and to investigate the pathogenesis of Mollicutes in the oral and anal mucosa before routine screening can be recommended in clinical practice.

"I don't see myself represented:" Strategies and considerations for engaging gay male Native Hawaiian and Other Pacific Islander teens in research and HIV prevention services

Significant efforts have been applied to the development of sexual health programs for minority young gay males. Given the absence of research with Native Hawaiian and other Pacific Islander (NHOPI) gay teen males, this study was done to assess how to reach them. Interviews were conducted with 20 NHOPI gay males ages 19-24 as near peers that can inform reaching teens. Data was analyzed using the Reflexive Thematic Analysis method. Three themes were identified: (1) Culture is a crucial factor for recruitment and engagement-whether participants realized it or not; (2) Confidentiality is key in recruitment to provide a safe space for NHOPI gay teen male research participation; and (3) NHOPI gay teen males experience multiple identity conflicts that must be considered for recruitment and engagement initiatives. Online recruitment efforts are optimal and should reflect distinct NHOPI cultures. More research is needed when it comes to understanding the cultural acceptance and understanding of homosexuality in NHOPI communities and how to integrate cultural education into recruitment methods and interventions.

Effectiveness of the SMART Sex Ed program among 13-18 year old English and Spanish speaking adolescent men who have sex with men

Adolescent men who have sex with men (AMSM) have a high HIV incidence and low utilization of testing and prevention services. However, very few HIV prevention programs exist that focus on the unique sexual health needs of AMSM. SMART is a stepped care package of eHealth interventions that comprehensively address the sexual and HIV prevention needs of AMSM. This study examines the impact of the first step of SMART, "SMART Sex Ed," on 13- to 18-year-old AMSM (n = 983) from baseline to three-month follow-up across 18 separate outcomes measuring HIV prevention attitudes, skills, and behaviors. We observed significant change from baseline to three-month post-intervention in nine HIV-related outcomes (e.g., receipt of HIV and STI test, HIV knowledge), as well as largely consistent effects across demographic subgroups (e.g., race, age, rural, low SES). Analyses observed no effects on condom use behaviors. SMART Sex Ed shows promise as an effective sexual health education program for diverse AMSM.

Pilot-testing a Multiplayer HIV and Sexually Transmitted Infection Prevention Video Game Intervention for Black Adolescent Girls: Protocol for a Randomized Controlled Trial

BACKGROUND

Black adolescent girls aged between 14 and 19 years are more likely than White girls to be diagnosed with a sexually transmitted infection (STI). As STI diagnosis is associated with an increase in the risk for HIV acquisition, an early intervention specifically tailored to Black adolescent girls is warranted. A web-based video game intervention has the potential to reach this demographic. Because studies of social and behavioral determinants of disease demonstrate the protective role of peer group structures on individual outcomes, a multiplayer game can facilitate opportunities to exchange and evaluate information, learn social norms, develop behavioral skills, and allow peers to influence attitudes and behavior. No prior research has examined the feasibility of a web-based multiplayer game intervention for this population.

OBJECTIVE

This study describes the protocol for a randomized controlled trial (RCT) pilot-testing the feasibility, acceptability, and limited efficacy of a multiplayer game-based intervention for increasing HIV and STI testing and condom use in Black adolescent girls.

METHODS

We enrolled 79 Black adolescent girls aged 14 to 19 years residing in the United States into a 2-arm parallel RCT. The intervention is a theory-based, community-informed, multiplayer game that can be played with peers on the web using videoconferencing software. The goal of the game is to empower Black adolescent girls to make healthy decisions regarding dating, relationships, and sex, thus reducing HIV and STI infection. Control condition participants received a list of resources after playing a time and attention control game. All study procedures were conducted via the internet. We conveniently sampled Black adolescent girls using web-based advertisements. Study assessments occurred at enrollment, 1 week, 1 month, and 4 months after enrollment. The primary outcome of this study is increased HIV and STI testing by Black adolescent girls. Secondary outcomes include increased condom use, self-efficacy to use condoms, positive attitudes toward condom use, intentions, harm perceptions, HIV and STI and pre-exposure prophylaxis knowledge, positive sexual norms, sexual communication with partners, and reduced incidence of sexual risk behaviors associated with HIV and STI transmission. Secondary outcomes also included assessment of intervention feasibility and acceptability.

RESULTS

From February to April 2022, a total of 79 Black adolescent girls were enrolled, with 40 (51%) having been randomized into the intervention condition and 39 (49%) into the control condition. At baseline, participant ages ranged from 14 to 19 (mean 16.4, SD 1.23) years.

CONCLUSIONS

Web-accessible game interventions overcome common impediments of face-to-face interventions presenting a unique opportunity to reach Black adolescent girls and improve their sexual health and self-efficacy. Trial data will provide information about the limited efficacy of the intervention and inform future web-based studies and a larger RCT aimed at improving the sexual health of Black adolescent girls.

Whose rights are being violated when receiving HIV and sexual and reproductive health services in Nigeria?

Background

In Nigeria, vulnerability status may increase the risk for the violation of human rights while receiving health care. The present study determined the proportion and profile of people who reported rights violation while accessing HIV and sexual and reproductive health (SRH) services.

Methods

This was a cross sectional study with data collected between February and March 2021. The dependent variables were patients’ rights to autonomy: right to privacy and confidentiality of medical records; right to be treated with respect, regardless of gender, race, religion, ethnicity, allegations of crime, disability or economic circumstances; right to decline or consent to participation in medical research, experimental procedures or clinical trials; right to quality care in accordance to prevailing standards; and right to complain and express dissatisfaction regarding services received. The independent variables were sexual identity (heterosexual/straight, gay, lesbian, bisexual, queer), HIV status (positive, negative, do not know), living with disability (yes/no), and access point to HIV services (public or donor funded/private). Five multivariate regression models were developed to determine associations between the dependent and independent variable after adjusting for age, education level (no formal education, primary, secondary, tertiary), sex (male, female, intersex), marital status (single, married, separated/divorced, cohabiting) and gender identity (male, female, transgender).

Results

Complete data from 2119 study participants were analysed. Transgender individuals had significantly higher odds of experiencing violation of their rights to privacy and confidentiality of medical records (AOR:1.70), right to be treated with respect (AOR:1.71), right to complain and express dissatisfaction regarding services received (AOR:1.57) and right to decline consent to participate in medical research, experimental research, experimental procedures or clinical trials (AOR:1.81) compared to individuals who were males.

Conclusion

A high proportion of recipients of HIV and SRH services in Nigeria reported rights violations. Transgender individuals appear to have higher risk and those in spousal relationships have lower risk for rights violations. Studies are needed to learn how to improve rights-based HIV and SRH service delivery in Nigeria especially for transgender individuals.

Self-Reported Use of HIV Preexposure Prophylaxis Is Highly Accurate Among Sexual Health Clinic Patients in New York City

ABSTRACT

In New York City, 91% of sexually transmitted infection clinic patients reported preexposure prophylaxis (PrEP) use that matched the detection of PrEP in their serum. Self-report had 80% sensitivity and 96% specificity ( κ = 0.79) compared with measured PrEP. Our findings suggest that self-report may be a valid indicator of PrEP uptake.

The rectal mucosal immune environment and HIV susceptibility among young men who have sex with men

Young men who have sex with men (YMSM) represent a particularly high-risk group for HIV acquisition in the US, despite similarly reported rates of sexual activity as older, adult MSM (AMSM). Increased rates of HIV infection among YMSM compared to AMSM could be partially attributable to differences within the rectal mucosal (RM) immune environment associated with earlier sexual debut and less lifetime exposure to receptive anal intercourse. Using an ex vivo explant HIV challenge model, we found that rectal tissues from YMSM supported higher levels of p24 at peak viral replication timepoints compared to AMSM. Among YMSM, the RM was characterized by increased CD4+ T cell proliferation, as well as lower frequencies of tissue resident CD8+ T cells and pro-inflammatory cytokine producing CD4+ and CD8+ T cells. In addition, the microbiome composition of YMSM was enriched for anaerobic taxa that have previously been associated with HIV acquisition risk, including Prevotella, Peptostreptococcus, and Peptoniphilus. These distinct immunologic and microbiome characteristics were found to be associated with higher HIV replication following ex vivo challenge of rectal explants, suggesting the RM microenvironment of YMSM may be uniquely conducive to HIV infection.

Sexual behaviour changes and HIV infection among men who have sex with men: evidence from an open cohort in China

BACKGROUND

The HIV epidemic in key populations such as men who have sex with men (MSM) is a public health issue of worldwide concern. China has seen an increase in newly diagnosed HIV infections through male-male sexual contact in the past decade. In a long-term cohort, how the complex behaviour pattern of MSM changed and the association with the HIV risk are unclear at present.

METHODS

This study was conducted from October 2011 to December 2019 in Tianjin. MSM were recruited by snowball sampling through online and offline ways. Demographic and sexual behavioural data were collected for analysis. Three indicators (condom use in last anal sex, frequency of condom use during anal sex and the number of sexual partners) were used to define the behaviour change. Participants with zero, one, and two or three risk indicators were categorised into behaviour types of 'protective', 'moderate', and 'fragile', respectively. Change in behaviour type between baseline and each visit was considered. Time-varying Cox models were performed to evaluate HIV infection risk.

RESULTS

Of 2029 MSM included in the study, 127 were new HIV diagnoses. The overall incidence rate was 3.36 per 100 person-years. The percentage of 'protective' and 'moderate' behaviour types had a conspicuous growth trend as the follow-up. Furthermore, the HIV incidence rate in each visit among different behaviour transition types showed a general downward trend as the number of total follow-up times increased. Individuals who remained in 'fragile' (adjusted HR (aHR): 25.86, 95% CI: 6.92 to 96.57) or changed from 'protective' to 'moderate' (aHR: 4.79, 95% CI: 1.18 to 19.47), 'protective' to 'fragile' (aHR: 23.03, 95% CI: 6.02 to 88.13), and 'moderate' to 'fragile' (aHR: 25.48, 95% CI: 6.79 to 95.40) between baseline and the last follow-up had a higher HIV risk. Gained risk indicators were associated with the increase of HIV risk (gained one indicator, aHR: 2.67, 95% CI: 1.68 to 4.24; gained two or three indicators, aHR: 4.99, 95% CI: 3.00 to 8.31) while losing just one risk indicator could halve the risk (aHR: 0.43, 95% CI: 0.21 to 0.90).

CONCLUSIONS

Among MSM in Tianjin, it is necessary to get timely behaviour change for those with high-incidence behaviour patterns while sustaining for those with low-incidence patterns.

Factors Associated With Partner Notification, Testing, and Positivity in HIV Partner Services Programs in the United States, 2013 to 2017

BACKGROUND

Human immunodeficiency virus (HIV) partner services are an essential component of comprehensive HIV prevention and care. We examined factors associated with partner notification, HIV testing, and HIV positivity among partners of HIV-diagnosed persons (index persons) contacted by Centers for Disease Control and Prevention (CDC)-funded state and local health departments.

METHODS

We analyzed partner service data submitted to the CDC by 61 state and local health departments from 2013 to 2017. Using multivariate Poisson regression-adjusted for clustering effects among partners reported by a common index person-we assessed associations between 3 outcomes of interest (partner notification, HIV testing, and HIV positivity) and the demographic characteristics, risk behaviors, geographic region, and service year of index persons and their partners.

RESULTS

A total of 51,368 sexual and/or needle-sharing partners were matched with 33,524 index persons. Of notifiable partners, 97.2% were notified of their potential HIV exposure, and 52.3% were tested for HIV. Among 21,842 notified and tested partners, 23.8% were newly diagnosed with an HIV infection. Partner notification, HIV testing, and HIV positivity were associated with both partner and index person characteristics (individually and interactively), geographic region, and year of service.

CONCLUSIONS

Partner service programs provided through CDC-funded health departments were effective in both partner notification and identification of undiagnosed HIV infection among partners. However, HIV testing rate among notified partners remained low. Implementing strategies to address gaps in HIV testing can contribute toward ending the HIV epidemic in the United States.

The Young Men and Media Study: A Pilot Randomized Controlled Trial of a Community-Informed, Online HIV Prevention Intervention for 14-17-Year-Old Sexual Minority Males

The Young Men and Media study developed and pilot tested a community-informed, online HIV prevention program for adolescent sexual minority males (ASMM) in the United States. The developed intervention uses nine interactive modules to increase sexual health knowledge, promote critical examination of pornography, and decrease sexual risk among ASMM. Participants (N = 154, age 14-17 years) were recruited online in Spring 2020 and randomized to the intervention (n = 77) or other existing HIV websites (n = 77). Of the 65 intervention participants who logged in to the website, most completed all nine modules and found the content useful (average module score 4.3 out of 5 stars). The intervention also showed improved HIV/STI knowledge, increased pornography knowledge, and reduced beliefs that pornography is an accurate depiction of male-male sex. Results indicate that the Young Men and Media intervention is feasible, acceptable, and may positively impact sexual health outcomes.

Material Hardship and Association With Sexual Risk Behavior Among Adolescent Sexual Minority Males in 3 US Cities-National HIV Behavioral Surveillance-Young Men Who Have Sex With Men, 2015

INTRODUCTION

Adolescent sexual minority males (ASMMs) are disproportionately affected by HIV relative to other youth within the United States. Social determinants of health have been explored among this population; however, economic determinants, such as material hardship, remain understudied. We examined the relationship between material hardship and sexual behavior among ASMMs aged 13-18 years residing in 3 US cities using 2015 data from CDC's National HIV Behavioral Surveillance among Young Men Who Have Sex with Men.

METHODS

Young men ages 13-18 years residing in 3 US cities were recruited through venue-based, respondent-driven, or Facebook sampling. We estimated adjusted prevalence ratios (aPRs) with 95% confidence intervals (CIs) for condomless anal intercourse (CAI) with a male sex partner in the past 12 months and with having 4 or more male sex partners in the past 12 months.

RESULTS

Of 547 ASMMs, 27% reported experiencing material hardship in the past 12 months. After adjusting for demographics, household characteristics, and city, ASMMs who experienced material hardship were more likely to report CAI with a male partner in the past 12 months (aPR: 1.55, 95% CI: 1.25 to 1.93) and to have had 4 or more male sex partners in the past 12 months (aPR: 1.44, 95% CI: 1.08 to 1.91).

DISCUSSION

More than a quarter of ASMMs experienced material hardship that was associated with increased sexual risk behavior among ASMMs. Incorporating services that address all unmet needs is important to consider for HIV prevention efforts for ASMMs.

Effects of Condom Use on Human Immunodeficiency Virus Transmission Among Adolescent Sexual Minority Males in the United States: A Mixed Epidemiology and Epidemic Modeling Study

BACKGROUND

We examined condom use patterns and potential population-level effects of a hypothetical condom intervention on human immunodeficiency virus (HIV) transmission among adolescent sexual minority males (ASMM).

METHODS

Using 3 data sets: national Youth Risk Behavior Survey 2015 to 2017 (YRBS-National), local YRBS data from 8 jurisdictions with sex of partner questions from 2011 to 2017 (YRBS-Trends), and American Men's Internet Survey (AMIS) 2014 to 2017, we assessed associations of condom use with year, age, and race/ethnicity among sexually active ASMM. Using a stochastic agent-based network epidemic model, structured and parameterized based on the above analyses, we calculated the percent of HIV infections averted over 10 years among ASMM ages 13 to 18 years by an intervention that increased condom use by 37% for 5 years and was delivered to 62% of ASMM at age 14 years.

RESULTS

In YRBS, 51.8% (95% confidence interval [CI], 41.3-62.3%) and 37.9% (95% CI, 32.7-42.3%) reported condom use at last sexual intercourse in national and trend data sets, respectively. In AMIS, 47.3% (95% CI, 44.6-49.9%) reported condom use at last anal sex with a male partner. Temporal trends were not observed in any data set (P > 0.1). Condom use varied significantly by age in YRBS-National (P < 0.0001) and YRBS-Trends (P = 0.032) with 13- to 15-year-olds reporting the lowest use in both; age differences were not significant in AMIS (P = 0.919). Our hypothetical intervention averted a mean of 9.0% (95% simulation interval, -5.4% to 21.2%) of infections among ASMM.

CONCLUSIONS

Condom use among ASMM is low and appears to have remained stable during 2011 to 2017. Modeling suggests that condom use increases, consistent with previous interventions, have potential to avert 1 in 11 new HIV infections among ASMM.

Structural Interventions for HIV Prevention and Care Among US Men Who Have Sex with Men: A Systematic Review of Evidence, Gaps, and Future Priorities

The preponderance of HIV interventions have been behavioral, targeting individual, dyadic, or group dynamics. However, structural-level interventions are required to decrease HIV transmission and increase engagement in care, especially for men who have sex with men (MSM), particularly Black and Latinx MSM. A systematic literature review was conducted to assess the current state of structural interventions; only two studies detailing structural interventions related to HIV for Black and Latinx MSM in the US were identified. An additional 91 studies which discussed structural-level barriers to optimal HIV outcomes among MSM, yet which did not directly evaluate a structural intervention, were also identified. While this paucity of findings was discouraging, it was not unexpected. Results of the systematic review were used to inform guidelines for the implementation and evaluation of structural interventions to address HIV among MSM in the U.S. These include deploying specific interventions for multiply marginalized individuals, prioritizing the deconstruction of structural stigma, and expanding the capacity of researchers to evaluate “natural” policy-level structural interventions through a standardization of methods for rapid evaluative response, and through universal application of sex, sexual orientation, and gender identity demographic measures.

Reimaging an AIDS free generation: Examining youth and young adults' personal agency and its association with HIV testing

Exploring youth and young adult's agency may be a way to increase HIV testing and help end the HIV epidemic. We used data from the National Survey of Teens and Young Adults (15-24) on HIV/AIDS (N = 1,437). Data were collected from September 21-October 1, 2012. The sample included 748 girls and 689 boys; and the mean age is 20 years (SD: 3.02). Youth and young adults completed a 40-question survey on attitudes and knowledge about HIV. Using a multivariable logistic regression analysis, study findings suggest that focusing on protective health behaviors like the role youth can play in ending the epidemic and hearing about an AIDS-free generation were both associated with an increase in HIV testing. Our study finds that enhancing the role and influence of personal agency can inform HIV prevention and intervention programs that are specific to youth.

Competence to Consent to Oral and Injectable PrEP Trials Among Adolescent Males Who Have Sex with Males

Adherence to oral pre-exposure prophylaxis (PrEP) is challenging for adolescent males who have sex with males (AMSM). Once adult trials comparing oral to longer lasting injectable PrEP are completed, there will be a need for adolescent studies. However, lack of data on adolescent consent capacity may sustain guardian permission requirements identified as a barrier to AMSM participation in prior PrEP trials. This online study assessed AMSM's (14-17 years) consent capacity for these trials, comparing performance to MSM (18-19 years) for whom guardian permission is not required. Applying the MacCAT-CR, participants (N = 214) viewed a video and mock consent form followed by open-ended and yes/no items. Cognitive diagnostic models and means testing analyses supported AMSM capacity to consent to these trials: 16-17 and most 14-15 year-olds, demonstrated consent understanding, appreciation and reasoning at 18-19 year-old levels. Data also identified vulnerabilities requiring attention during informed consent.

Modeling the Impact of PrEP Programs for Adolescent Sexual Minority Males Based on Empirical Estimates for the PrEP Continuum of Care

PURPOSE

Pre-exposure prophylaxis (PrEP)-an effective and safe intervention to prevent HIV transmission-was recently approved by the Food and Drug Administration for use by adolescents. Informed by studies of sexual behavior and PrEP adherence, retention, and promotion, we model the potential impact of PrEP use among at-risk adolescent sexual minority males.

METHODS

We simulate an HIV epidemic among men who have sex with men (MSM) aged 13-39. We assume adult MSM ages 19-39 have had PrEP available for 3 years with 20% coverage among eligible MSM based on the Centers for Disease Control and Prevention guidelines. PrEP interventions for ages 16-18 are then simulated using adherence and retention profiles drawn from the ATN113 and Enhancing Preexposure Prophylaxis in Community studies across a range of uptake parameters (10%-100%). Partnerships across age groups were modeled using parameterizations from the RADAR study. We compare the percent of incident infections averted (impact), person-years on PrEP per infection averted (efficiency), and changes in prevalence over 10 years.

RESULTS

As compared to no PrEP use, baseline PrEP adherence and retention among adolescent sexual minority males drawn from the ATN113 and Enhancing Preexposure Prophylaxis in Community studies averted from 2.8% to 41.0% of HIV infections depending on the fraction of eligible adolescent sexual minority males that initiated PrEP at their annual health-care visit. Improved adherence and retention achieved with an array of focused interventions from real-world settings increased the percent of infections averted by as much as 26%-70%.

CONCLUSIONS

Empirically demonstrated improvements in the PrEP continuum of care in response to existing interventions can substantially reduce incident HIV infections among adolescent sexual minority males.

Awareness and Willingness to Use Biomedical Prevention Strategies for HIV Among Sexual and Gender Minority Youth: Results From a National Survey

PURPOSE

Sexual and gender minority youth (SGM), an umbrella term encompassing gay, bisexual, and transgender youth, experience disproportionately high rates of new HIV infections, and recent advances in biomedical HIV prevention modalities hold promise in reducing new infections. However, the extent to which SGM youth are aware of and willing to use these modalities is unknown.

METHODS

Using data from the Survey of Today's Adolescents Relationships and Transitions, we analyze awareness of and willingness to take HIV pre-exposure prophylaxis (PrEP), nonoccupational HIV post-exposure prophylaxis, and rectal microbicides among adolescent sexual minority males aged 13-18 years and transgender youth aged 13-24 years.

RESULTS

Overall, we found a majority of our respondents were not aware of any of these prevention modalities. Across both subsamples, age and outness to a health care provider were associated with increased PrEP awareness, and any anal sex was associated with PrEP willingness.

CONCLUSIONS

These findings highlight the importance of provider education on how to discuss SGM issues with patients and educate them about HIV prevention options.

Learning About HIV: Predicting the Sources of Knowledge That Matter Regarding HIV Testing Among a National Sample of Black and Latinx Adolescents and Young Adults in the United States

This study investigated the knowledge and beliefs of a nationally representative sample of youth and young adults about HIV based on the microsystems and mesosystems of the ecodevelopmental theory. We used a stratified sample (n = 538) of Black and Latinx adolescents and young adults in the United States, 15-24 years of age, at risk of becoming infected with HIV to assess the source of their HIV knowledge and its association with HIV testing to identify modifiable factors that can support the development of interventions addressing HIV-related risks. Using a logistic regression analysis, findings suggest that identifying protective health behaviors, such as providing adolescents and young adults with sexual health information that is accurate, trustworthy, and safe, could be one way to reduce their risk of HIV infection. Expanding knowledge about the important role and influence of sources of HIV-related knowledge on testing behaviors can inform HIV prevention and intervention programs specific to this population.

Family Factors and HIV-Related Risk Behaviors Among Adolescent Sexual Minority Males in Three United States Cities, 2015

Purpose: We examined the relationship between family factors and HIV-related sexual risk behaviors among adolescent sexual minority males (ASMM) who are affected disproportionately by HIV. Methods: We analyzed results from the National HIV Behavioral Surveillance among Young Men Who Have Sex with Men. Adolescent males ages 13-18 who identified as gay or bisexual, or who reported attraction to or sex with males were interviewed in 2015 in Chicago, New York City, and Philadelphia. Separate log-linked Poisson regression models were used to estimate associations between family factors and sexual risk behaviors. Results: Of the 569 ASMM, 41% had condomless anal intercourse in the past 12 months, 38% had ≥4 male sex partners in the past 12 months, and 23% had vaginal or anal sex before age 13. ASMM who had ever been kicked out of their house or run away, those who were out to their mother, and those who were out to their father, were more likely to engage in sexual risk behaviors. ASMM who were currently living with parents or guardians and those who received a positive reaction to their outness by their mother were less likely to engage in sexual risk behaviors. Conclusion: Our findings highlight the important role of family factors in HIV risk reduction among ASMM. A better understanding of the complex dynamics of these families will help in developing family-based interventions.

Binge Drinking, Non-injection Drug Use, and Sexual Risk Behaviors among Adolescent Sexual Minority Males, 3 US Cities, 2015

In 2016, more than 90% of HIV diagnoses among young men aged 13-19 years were attributed to male-male sexual contact. Little is known about how binge drinking and non-injection drug use may be associated with risky sexual behavior among adolescent sexual minority males (ASMM). Using data from the National HIV Behavioral Surveillance, we examined how binge drinking and non-injection drug use may be associated with sexual risk among ASMM. ASMM were recruited for interviews in 3 cities: Chicago, New York City, and Philadelphia. Among 16-18-year-olds (N = 488), we evaluated the association between binge drinking (≥ 5 drinks in one sitting in the past 30 days), non-injection drug use (past 12-month use of methamphetamines, powder cocaine, downers, painkillers, ecstasy, poppers, and "other"), and two past 12-month sexual risk outcomes: condomless anal intercourse with a casual partner and having multiple sex partners. We used log-linked Poisson regression models with robust standard errors to estimate prevalence ratios (PR) and 95% confidence intervals (CI). Overall, 26% of 16-18-year-old ASMM binge drank, and 21% reported non-injection drug use. Among ASMM who binge drank, 34% reported condomless anal intercourse with a casual partner compared with 22% of those who did not (PR: 1.53, 95% CI: 1.04-2.26). Similarly, 84% of ASMM who binge drank reported having multiple partners compared with 61% of those who did not (PR: 1.38, 95% CI: 1.09-1.76). Among ASMM who used non-injection drugs, 37% reported condomless anal intercourse compared with 22% of those who did not (PR: 1.70, 95% CI 1.09-2.50), while 86% of those who used non-injection drugs had multiple partners compared with 62% of those who did not (PR: 1.40, 95% CI: 1.06-1.80). Our findings suggest that the prevalence of substance misuse is high among sexual minority youth and is associated with sexual risk in this population. Our findings highlight the need for high-quality HIV prevention programs for ASMM especially as HIV prevention programs for this population are scarce.

Identifying major drivers of incident HIV infection using recent infection testing algorithms (RITAs) to precisely inform targeted prevention

BACKGROUND

Recent infection testing algorithms (RITAs) incorporating clinical information with the HIV recency assay have been proven to accurately classify recent infection. However, little evidence exists on whether RITAs would help in precisely identifying major drivers of the ongoing HIV epidemic.

METHODS

HIV recency test results and clinical information were collected from 1152 newly diagnosed HIV cases between 2015 and 2017 in Dehong prefecture of Yunnan province, and the efficacy of four different RITAs in identifying risk factors for new HIV infection was compared.

RESULTS

RITA 1 uses the recency test only. RITA 2 and RITA 3 combine the recency test with CD4+ T cell count and viral load (VL), respectively. RITA 4 combines both CD4+ T cell count and VL. All RITAs identified the MSM group and young people between 15 and 24 years as risk factors for incident HIV infection. RITA 3 and RITA 4 further identified the Dai ethnic minority as a risk factor, which had not been identified before when only the HIV recency test was used.

CONCLUSIONS

By comparing different RITAs, we determined that greater accuracy in classifying recent HIV infection could help elucidate major drivers impacting the ongoing epidemic and thus inform targeted interventions.

HIV and Sexual Health Services Available to Sexual and Gender Minority Youth Seeking Care at Outpatient Public Mental Health Programs in Two California Counties

Purpose: Sexual and gender minority youth (SGMY, ages 16-24 years) face disparities in sexually transmitted infections (STIs) and HIV, in part, due to exposure to settings and behaviors that may harm youth's physical and mental health. This study examines the scope of sexual health and HIV services available to youth living with serious mental illness (SMI), including SGMY, seeking care at publicly funded outpatient mental health programs. Methods: Between 2018 and 2019, we surveyed 183 managers of mental health programs serving youth living with SMI of ages 16-24 years, including SGMY, in San Diego and Los Angeles counties. Participants reported on programs' target populations, sexual health/HIV service provision, and the use of peer providers. Descriptive statistics and Pearson chi-square tests were used to describe sexual health/HIV services and identify programmatic characteristics associated with providing these services. Results: Overall, 46% of all programs surveyed provided sexual health/HIV services. Of these, 62% provided HIV education, 81% provided sexual/reproductive health education, and 69% provided sexual/reproductive health education tailored for lesbian, gay, bisexual, queer, intersex (LGBQI) youth. Peers often provided these services. Chi-squared tests showed that programs employing peer specialists (p=0.009) and targeting LGBQI youth (p=0.045) were significantly more likely to provide sexual health/HIV services. Conclusion: The use of peer providers may reduce stigma around sexual/HIV service utilization and promote SGMY's trust. Publicly funded outpatient mental health programs serving youth and especially those actively engaging SGMY may consider also offering onsite HIV, STI, and sexual health services, creating a one-stop-shop approach.

Exploring potential implementation barriers and facilitators of the SMART Program, a stepped-care package of eHealth HIV prevention interventions for adolescent men who have sex with men

Little is known about how to best implement eHealth HIV interventions for adolescent men who have sex with men (AMSM) in real-world settings. In response, our current study describes formative implementation research with community-based organizations (CBOs) in preparation for future implementation of the SMART Program, a stepped-care package of three interventions adapted for AMSM. In-depth interviews focusing on eHealth implementation were conducted with a convenience sample of 12 stakeholders from nine CBOs that actively implemented sexual-minority-focused HIV/AIDS prevention programs. Qualitative analysis was conducted using Dedoose to identify salient themes. Most programs implemented at the CBOs engaged adult MSM for HIV prevention, but CBOs reported less experience with outreach of AMSM for HIV prevention. While comfortable with and skilled at implementing traditional in-person HIV prevention programs, interviewees reported that eHealth programs fell outside of their organizations' technical capacities. They suggested specific strategies to facilitate successful implementation of SMART and other eHealth programs, including technical-capacity-building at CBOs, better training of staff, and partnering with a national coordinating center that provides support for the technology. Overall, the CBOs reported enthusiasm for the SMART Program and thought it an efficient way to bridge their current gaps in online programming and lack of AMSM HIV prevention strategies.

Age- and Race/Ethnicity-Specific Sex Partner Correlates of Condomless Sex in an Online Sample of Hispanic/Latino, Black/African-American, and White Men Who Have Sex with Men

We sought to identify and compare correlates of condomless receptive anal intercourse with HIV-positive or unknown status partners (CRAI) for younger (< 25 years) and older (≥ 25 years) Hispanic/Latino, black/African-American, and white men who have sex with men (MSM). Baseline data from the Evaluation of Rapid HIV Self-Testing among MSM Project (eSTAMP), a randomized controlled trial with MSM (n = 2665, analytical sample size = 2421), were used. Potential correlates included participants' sociodemographic characteristics and HIV status as well as the characteristics of participants' partners. Younger Hispanic/Latino and black men were most likely to report having older sex partners (≥ 50% of partners being at least 5 years older), and having older partners was a significant correlate of CRAI among younger Hispanic/Latino and white men. Regardless of race/ethnicity, not knowing one's HIV status was a significant correlate of CRAI among younger men, whereas having a black sex partner was a significant correlate among older men. HIV prevention initiatives could address these and other correlates specific to race/ethnicity groups to target their prevention resources and messaging.

Cost-effectiveness of frequent HIV screening among high-risk young men who have sex with men in the United States

BACKGROUND

Of new HIV infections in the US, 20% occur among young men who have sex with men (YMSM, ages 13-24), but >50% of YMSM with HIV are unaware of their status. Using Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) data, we projected the clinical benefit and cost-effectiveness of frequent HIV screening among high-risk YMSM from age 15.

METHODS

Using a mathematical simulation, we examined 3 screening strategies: Yearly, 6-monthly, and 3-monthly, each in addition to the Status quo (SQ, 0.7-10.3% screened/year, stratified by age). We used published data (YMSM-specific when available) including: HIV incidences (0.91-6.41/100PY); screen acceptance (80%), linkage-to-care/antiretroviral therapy (ART) initiation (76%), HIV transmission (0.3-86.1/100PY, by HIV RNA), monthly ART costs ($2,290-$3,780), and HIV per-screen costs ($38). Projected outcomes included CD4 count at diagnosis, primary HIV transmissions from ages 15-30, quality-adjusted life expectancy, costs, and incremental cost-effectiveness ratios (ICERs, $/quality-adjusted life-year saved [QALY]; threshold ≤$100,000/QALY).

RESULTS

Compared to SQ, all strategies increased projected CD4 at diagnosis (296 to 477-515 cells/µL) and quality-adjusted life expectancy from age 15 (44.4 to 48.3-48.7 years) among YMSM acquiring HIV. Compared to SQ, all strategies increased discounted lifetime cost for the entire population ($170,800 to $178,100-$185,000/person). Screening 3-monthly was cost-effective (ICER: $4,500/QALY) compared to SQ and reduced primary transmissions through age 30 by 40%. Results were most sensitive to transmission rates; excluding the impact of transmissions, screening Yearly was ≤$100,000/QALY (ICER: $70,900/QALY).

CONCLUSIONS

For high-risk YMSM in the US, HIV screening 3-monthly compared to less frequent screening will improve clinical outcomes and be cost-effective.

Very High HIV Incidence and Associated Risk Factors in a Longitudinal Cohort Study of Diverse Adolescent and Young Adult Men Who Have Sex with Men and Transgender Women

To report HIV incidence and associated factors among young men who have sex with men (YMSM) and transgender women (TW). Data were collected February 2015 to July 2018 in the RADAR longitudinal cohort study of YMSM/TW aged 16-29 years (N = 1093). Data included tests for HIV and rectal STIs and self-reported sexual behaviors and networks characteristics. HIV incidence rates were 2.91 per 100 person years (44 seroconversions among 1513 person years). Incidence was significantly higher in Black participants than white (IRR 8.81; 95% CI 2.72-45.26) and Latinx (IRR 3.15; 1.49-7.28) participants, but no significant differences by gender identity were found. Testing positive for rectal STIs (HR 2.50; 95% CI 1.27-4.92) and sex with a partner from a high HIV incidence community area (HR 2.46; 95% CI 1.19-5.07) were associated with higher incidence. HIV incidence was very high and Black YMSM/TW experienced higher HIV incidence attributable to partner race and geographic residence. Rectal STIs were associated with increased HIV incidence.

Factors Associated With HIV Testing in Teenage Men Who Have Sex With Men

BACKGROUND

Adolescent men who have sex with men (AMSM) have a high rate of HIV diagnoses. An estimated 14.5% of HIV infections in the United States are undiagnosed; but among 13- to 24-year-olds, the rate is 51.4%. We describe HIV testing rates and identifies salient individual, family, school, and health care influences among AMSM.

METHODS

Data were collected as part of SMART, an ongoing pragmatic trial of an online HIV prevention intervention for AMSM (N = 699). Measures included lifetime HIV testing, demographics, sexual behaviors, condom use, HIV education from school and family, sexual health communication with doctors, HIV knowledge, and risk attitudes.

RESULTS

Only 23.2% of participants had ever had an HIV test. Rates of testing increased with age (5.6% in 13- to 14-year-olds; 15.8% in 15- to 16-year-olds; 37.8% in 17- to 18-year-olds), and sexual experience was a strong predictor of testing (odds ratio: 6.54; 95% confidence interval: 3.95-11.49; P < .001). Most participants had a regular doctor (67.5%), but few had conversations about same-sex sexual behaviors (21.3%), HIV testing (19.2%), or sexual orientation (29.2%). Speaking to a doctor about HIV testing had a large effect (odds ratio: 25.29; confidence interval: 15.91-41.16; P < .001), with 75.4% who had such conversations having been tested, compared to only 10.8% of those who had not had such conversations.

CONCLUSIONS

Despite higher risk, few participants reported ever having received an HIV test. Data indicate pediatricians are an important, but largely untapped, source of testing and could be integral to achieving testing rates needed to end the epidemic.

Navigating the Long Road Forward for Maximizing PrEP Impact Among Adolescent Men Who Have Sex with Men

Preexposure prophylaxis (PrEP) has tremendous potential to decrease new HIV infections among populations at high risk, such as men who have sex with men (MSM). That potential is already becoming realized among adult MSM, where PrEP uptake has increased rapidly in the past several years. However, expanding PrEP access to adolescent MSM (AMSM) will be more challenging. This commentary reviews the existing scientific literature relevant to PrEP use for AMSM and highlights critical areas in need of further attention before PrEP is likely to impact the HIV epidemic among adolescents. We highlight concerns that need to be addressed in the areas of (1) achieving adequate coverage of PrEP in the adolescent population, (2) increasing awareness and access, (3) supporting adherence and maintenance, and (4) ensuring that PrEP does not perpetuate existing disparities. Across all of these domains, we highlight the central roles of parents and healthcare providers in supporting AMSM PrEP utilization. Finally, we suggest a number of areas of future research that must be addressed before PrEP is likely to see wide implementation among AMSM.

Sexually transmitted infection screening and diagnosis among adolescent men who have sex with men, three US cities, 2015

Adolescent men who have sex with men (MSM) are at increased risk for sexually transmitted infections (STIs) and HIV; however, data documenting STI screening, STI burden, and associated risk factors for STIs are extremely limited. Using 2015 data from the National HIV Behavioral Surveillance among Young MSM, we examined self-reported STI screening and STI diagnosis of chlamydia, gonorrhea, or syphilis among sexually active adolescent MSM by selected characteristics. Analysis of STI diagnosis was limited to participants who reported an STI screening. Differences in STI screening and STI diagnosis and factors associated with screening and diagnosis were examined using bivariate and multivariable binomial regression models. Less than half of adolescent MSM reported having ever been screened for an STI. Among these, more than a quarter reported having ever been diagnosed with chlamydia, gonorrhea, or syphilis. STI screening was associated with visiting a healthcare provider in the past 12 months and having ever been tested for HIV. Having ever had an STI diagnosis was associated with the participant age of 18 years and having sex before 13 years old. Among adolescent MSM, STI screening was suboptimal and STI burden was significant. STI intervention and prevention programs are urgently needed to promote STI awareness, timely screening, and early diagnosis to interrupt transmission among this vulnerable population.

Mental health, social support, and HIV-related sexual risk behaviors among HIV-negative adolescent sexual minority males: three U.S. cities, 2015

We examined the association between mental health issues, social support, and HIV among adolescent sexual minority males (SMM), who are disproportionally affected by HIV. National HIV Behavioral Surveillance among Young Men Who Have Sex with Men (NHBS-YMSM) data among SMM aged 13-18 years were collected in three cities (Chicago, New York City, and Philadelphia). Separate log-linked Poisson regression models were used to estimate associations between mental health issues and social support (general and family), and 3 HIV-related sexual risk behavior outcomes: past-year condomless anal intercourse (CAI) with a male partner, past-year sex with ≥ 4 partners, and first vaginal or anal sex before age 13. Of 547 adolescent SMM, 22% reported ever attempting suicide and 10% reported past-month suicidal ideation. The majority (52%) reported depression and anxiety. Thirty-nine percent reported CAI, 29% reported ≥ 4 sex partners and 22% reported first sex before age 13. Ever attempting suicide, suicidal ideation, and depression and anxiety were associated with CAI. Separately, ever attempting suicide and lack of family support were associated with  ≥ 4 sex partners. None of the mental health or support measures were associated with having sex before age 13. General social support was not associated with any sexual risk behaviors. Mental health issues are common among adolescent SMM and associated with sexual risk behaviors. Including mental health support in comprehensive HIV prevention for adolescent SMM could potentially reduce HIV risk in this population.

Brief Report: Role of Sociobehavioral Factors in Subprotective TFV-DP Levels Among YMSM Enrolled in 2 PrEP Trials

BACKGROUND

Young men who have sex with men (YMSM) experience disparities in HIV acquisition more than any other group. Daily oral pre-exposure prophylaxis (PrEP) with tenofovir/emtricitabine has been shown to effectively prevent HIV transmission in YMSM; however, recent studies suggest that young Black men who have sex with men experience subprotective levels of tenofovir diphosphate more frequently than other groups.

SETTING

Combined data from Adolescent Medicine Trials Network for HIV/AIDS Interventions (ATN) 110/113, 2 open-label PrEP studies that provided PrEP and evidence-based behavioral interventions to YMSM aged 15-22 years.

METHODS

Bivariate and logistic regression analyses were used to examine sociodemographic and behavioral factors associated with protective tenofovir diphosphate levels (defined as ≥700 fmol/punch) in ATN 110/113 data.

RESULTS

In bivariate analysis, self-identified Black participants, residential displacement due to sexual orientation, low perceived risk, and stigma with the medication were associated with subprotective levels. Hispanic ethnicity was associated with protective levels. In the final models, Black males were less likely to have subprotective levels than non-Black males at 4, 8, and 12 weeks. Self-reported displacement due to sexual orientation was associated with subprotective levels, whereas older age was as associated with protective levels.

CONCLUSIONS

These findings highlight how future behavioral research and biomedical prevention efforts in YMSM will need to address PrEP disparities that may occur in young Black men who have sex with men, perception of risk, and lack of key supportive housing during this period that may be critical factors that contribute to HIV acquisition.

University of North Carolina/Emory Center for Innovative Technology (iTech) for Addressing the HIV Epidemic Among Adolescents and Young Adults in the United States: Protocol and Rationale for Center Development

Background

Over a fifth of all new HIV infections in the United States occur among persons aged 13 24 years, with most of these diagnoses occurring among gay and bisexual males (81%). While the epidemic of HIV in the United States has leveled off for many age groups, the annual number of new HIV diagnoses among young men who have sex with men (YMSM; 13-24 years old) remains high. Traditional approaches to continuum improvement for youth have been insufficient, and targeted interventions are urgently needed for young people at risk for or infected with HIV. Interventions delivered through mobile health technology represent a promising approach for improving outcomes in this population. Mobile phones have nearly reached saturation among youth, making mobile technology a particularly promising tool for reaching this population.

Objective

The University of North Carolina/Emory Center for Innovative Technology (iTech) is a National Institutes of Health cooperative agreement as part of the Adolescent Medicine Trials Network for HIV/AIDS Interventions. iTech aims to impact the HIV epidemic by conducting innovative, interdisciplinary research on technology-based interventions across the HIV prevention and care continuum for adolescents and young adults in the United States, particularly YMSM, by providing the following: (1) evaluation of novel approaches to identifying youth with undiagnosed HIV infections; (2) evaluation of multilevel, combination prevention approaches, particularly relevant to gender- and sexual-minority youth facing co-occurring health risks; (3) evaluation of uptake of and adherence to biomedical prevention modalities; and 4) evaluation of interventions designed to promote or optimize engagement in care and antiretroviral therapy adherence in HIV-positive youth, to optimize viral load suppression.

Methods

iTech brings together multidisciplinary experts in the fields of adolescent HIV treatment and prevention, development and evaluation of technology-based interventions, HIV surveillance and epidemiology, and intervention design and evaluation. This initiative will support 8 efficacy trials and 2 exploratory projects, each led by 2 principal investigators. Taken together, the studies address all of the key steps of the HIV prevention and care continuum for youth in the United States. Each proposal uses technology in a scientifically rigorous and innovative way to access, engage, and impact at-risk or infected youth. Nine iTech subject recruitment venues are spread across 8 US cities. Three cores (management, analytic, and technology) support all iTech activities and form the research network’s infrastructure, facilitating all aspects of study implementation and evaluation.

Results

Formative work has already begun on many of the above-mentioned iTech trials. We expect the first randomized controlled trials to begin in mid-2018. Additional details can be found in the individual intervention protocol papers in this issue.

Conclusions

Through its comprehensive research portfolio, iTech aims to effectively advance HIV prevention and care for youth through technology-based, youth-relevant interventions that maximize adaptability and sustainability.
