RESUMEN

Pre-exposure prophylaxis (PrEP) is effective in preventing HIV transmission, but uptake and adherence among young men who have sex with men (YMSM) remains suboptimal. New PrEP formulations may enhance PrEP use, but little is known about their acceptability. We enrolled 39 cis- and transgender YMSM (age 18-34) from Boston, MA; Jackson, MS; Birmingham, AL; and New Orleans, LA, who participated in video-based focus groups (n = 30) or in-depth interviews (n = 9) to examine how new PrEP products (e.g., injections, monthly pills, implants) are perceived and might be improved for YMSM. Focus groups were transcribed, coded, and analyzed using grounded theory and content analysis. Nearly half (46%) of participants were Black; 11% identified as Hispanic. Seventy-nine percent were PrEP experienced. Product preference was driven by the desire for flexible, safe, effective, and affordable PrEP options. A majority of participants preferred subcutaneous injections every 6 months or monthly pills dispersed in 3 or 4 doses. Subcutaneous injections and batched monthly pills were favored by those with demanding schedules and those who desired fewer provider visits; monthly pills were more appealing for those who feared needles. Despite broad preferences for longer-acting products for convenience, participants raised concerns regarding side effects and waning protection after missed doses. Participants felt that more education about safety and efficacy profiles of new products could influence their attitudes. These findings suggest that it is important to prioritize YMSM's dynamic lifestyles during product development, and that product safety and efficacy information should be accessible in youth-friendly language.

RESUMEN

Nitrite inhalants (poppers) are associated with HIV transmission and commonly used among young men who have sex with men (YMSM), a group at increased risk for HIV. Significant research gaps exist in understanding the context in which YMSM use poppers. Qualitative interviews were conducted with 15 YMSM (22-31 years) with HIV to better understand the context in which poppers are used and their impacts on HIV care outcomes, such as care retention and antiretroviral adherence. The Social Ecological Model was applied to understand intrapersonal, interpersonal, community, and system level influences on popper use. Factors influencing popper use included: ubiquity of popper use in sexual settings, introduction to poppers by casual sexual partners, patient-HIV provider communication surrounding poppers, neighborhood, substance use and HIV care systems, and the legal status of poppers. Implications for clinical care, public health, policy, and future research are discussed.

RESUMEN

INTRODUCTION: Few studies focused on the Pre-Exposure Prophylaxis (PrEP) -related aspects, and the applicability of prior evidence to young men who have sex with men (YMSM) students was unknown. This study aimed to assess the awareness, willingness, uptake, and adherence (AWUA) to PrEP among YMSM students in China and to explore the associated factors with these stages. METHODS: A cross-sectional survey with a sizable sample of 1151 was conducted among YMSM students aged 16 and above, who self-identified as men who have sex with men(MSM) and resided in mainland China between October 20 and December 20, 2021. The chi-square test and Fisher's exact test were used for univariate analysis, followed by multivariable logistic regression analysis of influencing factors at all levels. RESULTS: According to the cascade analysis approach, 88.71% of the participants were aware of PrEP, among which 66.7% expressed willingness to use it. Among those who were willing to use PrEP, only 13.80% took it, and of those who took it, 44.68% adhered to it. The students taking PrEP were those with higher education (OR = 4.239, 95% CI: 1.334-13.467), residence in pilot cities (OR = 2.791, 95% CI: 1.498-5.198), residence in high-risk areas (OR = 5.082, 95% CI: 2.224-11.612), engagement in multi-person sexual behavior (OR = 2.186, 95% CI: 1.236-3.867), and substance use (OR = 1.908, 95% CI: 1.167-3.118). Furtherly, students with higher adherence to PrEP were likely to have receptive sexual behaviors (OR = 8.702, 95% CI: 2.070-36.592), absence of substance use (OR = 4.468, 95% CI: 1.371-14.561), and uptake of PrEP through daily oral route. (OR = 7.065, 95% CI: 1.699-29.371). CONCLUSION: YMSM students exhibit distinct patterns of "high awareness, low willingness, low uptake, and low adherence" to PrEP. Strategies for reduction in the acquisition of HIV prioritizing the current features of utilizing PrEP were urgently warranted.

RESUMEN

INTRODUCTION: In China, young men who have sex with men (YMSM) are one of the groups most at risk of HIV/AIDS. The uptake of pre-exposure prophylaxis (PrEP) among YMSM has not been well documented. A cascade analysis of awareness, willingness, use and adherence with regard to PrEP was conducted separately among YMSM students and non-students. METHODS: From 20 October to 30 December 2021, all adolescents aged 16-24 years were selected for the study from among MSM recruited from 31 provincial administrative regions in mainland China. Participants were included in a cross-sectional study of awareness, willingness, use and adherence with regard to PrEP among YMSM. Logistic regression modelling was used to identify factors associated with the four outcomes. RESULTS: Among 1014 student and 866 non-student YMSMs, respectively, 88.07% and 81.64% had heard of PrEP; 58.16% and 50.35% were willing to use PrEP; 7.59% and 7.62% had used PrEP; and 3.16% and 3.58% had adhered to PrEP. Among students, those living in high-risk areas and pilot cities and those who had engaged in commercial sex and group sex had a positive effect on PrEP use, and the same trends were found among non-students living in high-risk areas and pilot cities and those who had engaged in group sex. 'Daily oral' and 'flexible' PrEP use positively influenced adherence among both groups. CONCLUSIONS: A differentiation strategy of PrEP promotion should be implemented among YMSM. Material support for students, such as financial resources, should increase, while non-students should increase their level of perception of HIV risk.

RESUMEN

Introduction: Parents and guardians are a potentially valuable source of sexual health information for adolescent sexual minority males (ASMM). The current study examines what sexual health topics ASMM report discussing with a parent/guardian and whether topics differ by outness about sexual attraction to other males. Methods: ASMM (N=154; ages 14-17) in the United States completed the baseline of an online sexual health intervention pilot in 2020. They reported which of twelve sexual health topics they discussed with a parent/guardian and if they had disclosed their sexual attraction to other males. Associations between topics discussed and outness to a parent/guardian were examined with Firth logistic regression. Results: Eighty-eight (57%) participants reported being out to a parent/guardian. Six sexual health topics were significantly more likely to be discussed if participants were out. The three categories with the largest differences by outness were how to: discuss with a partner what they would not like to do sexually (aOR = 7.0, 95% CI: 2.0-24.6), use condoms (aOR = 5.9, 95% CI: 2.3-15.1), and prevent HIV/AIDS (aOR = 3.5, 95% CI = 1.4-8.7). Conclusions: Interventions on parental/guardian provision of sexual health information are needed to ensure ASMM receive relevant sexual health knowledge.

RESUMEN

Young men who have sex with men (YMSM) in Nigeria are ten times more likely to be living with HIV-1 than other young men. Due to stigma and criminalization of same-sex sexual behavior, YMSM sexual networks are likely to overlap with those of the general population, leading to a generalized HIV-1 epidemic. Due to limited research on social/sexual network dynamics related to HIV-1 in Nigeria, our study focused on YMSM and sought to assess the feasibility and acceptability of collecting social and sexual network data in Network Canvas from individuals newly diagnosed with HIV-1 in Ibadan, Nigeria. The Network Canvas software was piloted at three sites in Ibadan, Nigeria to collect social/sexual network data from 151 individuals newly diagnosed with HIV-1. Our study sample included 37.7% YMSM; participants reported a mean of 2.6 social alters and 2.6 sexual alters. From the 151 egos and 634 alters, 85 potential unique individuals (194 total) were identified; 65 egos/alters were collapsed into 25 unique individuals. Our success collecting network data from individuals newly diagnosed with HIV-1 in Ibadan demonstrates clear feasibility and acceptability of the approach and the use of Network Canvas to capture and manage these data.

RESUMEN

BACKGROUND: Adherence and retention concerns raise questions about the effectiveness and cost-effectiveness of oral HIV pre-exposure prophylaxis (PrEP) in young men who have sex with men (YMSM). METHODS: Using an adolescent-focused simulation model, we compared annual HIV screening alone with tenofovir disoproxil fumarate/emtricitabine-based oral PrEP with every 3-month HIV screening in YMSM (aged 15-24) at increased risk of HIV. Data derived from published sources included: age-stratified HIV incidence/100 person-years (PY) on- or off-PrEP (0.6-10.1 or 0.4-6.4), PrEP retention at 6 years (28%), transmissions by HIV RNA level (0.0-78.4/100PY) and annual costs of antiretroviral therapy ($32 000-69 000), HIV care ($3100-34 600), and PrEP program/generic drug ($900/360). Outcomes included transmissions (percent of cohort infected), quality-adjusted life-years (QALYs), costs ($), and incremental cost-effectiveness ratios ($/QALY). We explored the sensitivity of findings to variation in HIV incidence and drug prices. RESULTS: Compared with annual screening alone, PrEP would increase QALYs (9.58 to 9.67), reduce new infections (37% to 30%), and decrease costs (by $5000) over 10 years. PrEP would remain cost-saving for HIV incidence off-PrEP ≥5.1/100PY or annual PrEP price ≤$1200. Over a lifetime horizon, PrEP would be cost-saving for HIV incidence off-PrEP ≥1.0/100PY, across all retention assumptions examined. PrEP would not be cost-effective at HIV incidence ≤0.1/100PY, regardless of drug price, due to programmatic costs. CONCLUSIONS: In US YMSM at increased risk of HIV, generic oral PrEP and every-3-month screening would be cost-saving compared with annual screening alone, even with high discontinuation and low adherence, over a range of HIV incidences.

RESUMEN

To compare the demographics, sexual risk behaviors, and substance use characteristics of two probability samples of young men who have sex with men (YMSM): one recruited using a geosocial networking application (GSNA) and one recruited using venues. In 2017 and 2018, a cross-sectional online survey was utilized with a sample of 122 YMSM recruited in Los Angeles, CA. Recruitment procedures included both venue-based (n = 68) and GSNA-based probability sampling (n = 54). Sample substance use, sexual risk behaviors (e.g., unprotected sex at last encounter), and demographics were compared using chi-square tests and t-tests. The samples significantly differed in demographics characteristics (e.g., race, education, employment, outness). Samples did not significantly differ in sexual risk variables. Regressions indicated significant differences (higher in the venue sample) in substance use (marijuana, prescription drugs, alcohol, and poppers) between the two samples. Results indicate that recruitment method impacts demographics and substance use prevalence levels for YMSM. GSNA- based recruitment appears to recruit samples from a broader range of social demographics. GSNA-based methods may be especially applicable to areas in which venues are not readily accessible (e.g., rural areas), allowing social research with the most marginalized sexual minority populations.

RESUMEN

BACKGROUND: Compared to young heterosexual men, young gay, bisexual and other men who have sex with men (YMSM) face a disproportionate burden of sexual health conditions. This disparity is occasioned by factors such as criminalization and stigmatization of same-sex practices, YMSM's limited access to non-judgmental and non-discriminatory health services, and challenges associated with healthcare delivery. We explored the attitudes and perspectives of tertiary academic institution-based healthcare providers (HCPs) toward provision of services to YMSM in Nairobi, Kenya. METHODS: In September 2021, six in-person focus group discussions (FGDs) were held with 36 HCPs drawn from six public tertiary academic institutions within the Nairobi metropolis. HCPs were drawn from six cadres: front office staff, nurses, clinicians, counsellors, laboratory technologists, and pharmaceutical technologists. Discussions were conducted in English, transcribed verbatim and analyzed thematically using NVivo version 12. RESULTS: Analysis showed that despite expressing disapproval of same-sex practices, HCPs recognized their professional duty to provide care to YMSM, voiced challenges they experienced when providing care to YMSM, and suggested possible strategies for improving care for YMSM. Disapproval of same-sex practices mainly stemmed from HCPs' personal values, societal norms and religious beliefs, though some HCPs identified religious principles such as the golden rule of "treating others as one would want to be treated" as motivation to providing care to YMSM. HCPs did not perceive criminalization of same-sex practices as a barrier to providing care to YMSM. Healthcare delivery challenges included inadequate knowledge and skills, a desire to "convert" YMSM's perceived deviant homosexual to the normative heterosexual orientation, secondary stigma from other HCPs, and healthcare settings that did not support YMSM to disclose same-sex practices. Suggestions for improving care comprised sensitization and training of HCPs, encouraging more HCP-YMSM interaction, providing YMSM-friendly and inclusive services, and advocacy for YMSM services. CONCLUSION: There is need for interventions to improve HCPs' knowledge of YMSM's health needs, build skills to respond to these needs, and foster affirming attitudes toward same-sex practices. By so doing, YMSM can hopefully be able to access services that meet their needs, and are non-discriminatory, non-stigmatizing and non-judgmental.

RESUMEN

New HIV infections disproportionately affect young men who have sex with men (YMSM). PrEP is effective in preventing HIV acquisition; however, adherence is critical and is often suboptimal among YMSM. Interventions addressing the unique PrEP adherence challenges faced by YMSM are needed. We conducted qualitative interviews with 20 HIV-negative, YMSM (ages 15-24) with a PrEP indication and 11 healthcare professionals to inform adaption of a PrEP adherence intervention (Life-Steps for PrEP) for YMSM. We explored environmental, healthcare, and individual factors influencing uptake, adherence, attitudes, and perspectives (including desired modifications) on the Life-Steps intervention. Interviews were analyzed using content analysis. Of YMSM study participants (mean age 21.6) 55% were White, 15% Hispanic, and 5% Black. Most YMSM were PrEP-experienced (70%). Healthcare professionals (6 prescribers, 1 nurse, 2 health educators, 2 other/unspecified) averaged 6.9 years of experience caring for YMSM. All described stigma as a barrier to PrEP; YMSM expressed concern around being perceived as "risky" and concern about inadvertent PrEP disclosure if family/friends found their medication, or if parental insurance was used. Difficulty with planning for potential adherence challenges were identified by both groups. YMSM highlighted benefits of a nurse-led intervention (i.e., adding "legitimacy"), but stressed need for nonjudgmental, "savvy" interventionists. YMSM expressed a desire for comprehensive YMSM-specific sexual health information. These findings informed modification and expansion of Life-Steps content. Results highlight key potential barriers, many of which center around privacy. Content that addresses PrEP stigma, disclosing PrEP use, navigating insurance, and planning ahead in a nonjudgmental environment by trusted providers emerged as important components of a YMSM-focused delivery of Life-Steps for PrEP.

RESUMEN

BACKGROUND: Young men who have sex with men (MSM), are a key population at higher risk of HIV infection yet they are underrepresented in research. We conducted a bio-behavioral survey to estimate HIV prevalence and associated risk factors among tertiary student MSM (TSMSM) in Nairobi, Kenya. METHODS: Between February and March 2021, 248 TSMSM aged ≥ 18 years who reported sex with another man in the past year participated in a respondent-driven sampling (RDS) based cross-sectional survey. Participants completed an electronically self-administered behavioral survey and provided a blood sample for HIV antibody testing, alongside urine, anorectal and oropharyngeal swabs for pooled testing of sexually transmitted infections using a multiplex nucleic acid amplification test. RDS-Analyst v.0.72 and Stata v.15 software were used for data analysis. Differences in proportions were examined using chi-square (χ2) test, and unweighted multivariate logistic regression was used to assess factors associated with HIV infection. RESULTS: HIV prevalence among study participants was 8.3%, whereas the weighted prevalence was 3.6% (95% CI: 1.3-6.0%). Median ages of participants, and at self-reported first anal sex with a man were 21(interquartile range [IQR] 20-22) and 18 (IQR 17-19) years, respectively. A majority (89.3%) of TSMSM owned a smart phone, 46.5% had ever used a geosocial networking app for MSM such as Grindr ® to find a sex partner, and a third (33.6%) met their last sex partner online.  Almost three-quarters (71.3%) had > 1 male sex partner in the year before the survey. A third (34.3%) did not use condoms with their last sex partner, 21.2% received money from their last sex partner and 40.9% had taken alcohol/another drug during their last sexual encounter. HIV infection was associated with studying in private institutions (adjusted odds ratio[AOR] = 6.0; 95% confidence intervals [CI] : 1.2-30.0, p = 0.027), preferring a sex partner of any age-younger, same or older (AOR = 5.2; 95 CI: 1.1-25.2, p = 0.041), last sex partner being > 25 years (AOR = 6.4; 95% CI: 1.2-34.6, p = 0.030), meeting the last sex partner online (AOR = 4.2; 95% CI; 1.1-17.0, p = 0.043) and testing positive for Neisseria gonorrhea (AOR = 7.8; 95% CI: 2.0-29.9, p = 0.003). CONCLUSIONS: HIV prevalence among TSMSM in Nairobi is alarmingly high, demonstrating a need for tailored prevention and control interventions for this young key population.

RESUMEN

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

RESUMEN

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.

RESUMEN

BACKGROUND: African American young men who have sex with men (YMSM) possess many intersecting identities that may increase their vulnerability to social stigmatization and discrimination, which yields a negative influence on their well-being and behaviors. These experiences often manifest as increased general and sexual risk-taking behaviors that place this particular group at an increased risk for HIV. This scenario is exacerbated by the lack of HIV prevention interventions specifically designed for African American YMSM. OBJECTIVE: In this paper, we discuss the development of research designed to refine, pilot, and evaluate the feasibility, acceptability, and preliminary efficacy of a behavioral intervention designed to build resilience and reduce substance use and HIV risk behaviors among African American YMSM. The overarching aim of this research, funded by the National Institutes of Health, is to further refine and pilot test an intervention called Young Men's Adult Identity Monitoring (YM-AIM). YM-AIM is a theory-driven, group-level intervention designed to help African American YMSM develop a healthy vision for their future (or possible future self) by defining a set of short-term and long-term goals in the areas of education, health, family, and intimate relationships. METHODS: Through partnerships with community members and community-based organizations, we will further strengthen and refine YM-AIM to include 3 new components: biomedical HIV prevention strategies (pre-exposure prophylaxis and postexposure prophylaxis); HIV and sexually transmitted infection (STI) testing and HIV care referral, drug screening, and drug treatment referral; and a youth mentoring component. We will recruit African American YMSM, aged 18 to 24 years, into 2 working groups; each group will consist of 6 to 8 members and will convene on a weekly basis, and each meeting will focus on one specific YM-AIM topic. This feedback will be used to further refine the intervention, which will then be evaluated for its feasibility and acceptability. Intervention outcomes include drug use in the past 30 days and 3 months, alcohol use, condomless sex, number of sex partners, and increasing condom use intention, condom use self-efficacy, HIV and STI testing recency and frequency, and linkage to care. RESULTS: As of June 2022, we completed phase 1 of Y2Prevent and launched phase 2 of Y2Prevent to begin recruitment for working group participants. Phase 3 of Y2Prevent is anticipated to be launched in September and is expected to be completed by the end of this project period in December 2022. CONCLUSIONS: Few youth-focused interventions have sought to help youth identify and develop the skills needed to navigate the social and structural factors that contribute to individual-level engagement in prevention among sexual minority youth. This research seeks to promote young men's adoption and maintenance of HIV-protective behaviors (eg, safer sex, pre-exposure prophylaxis use, HIV and STI testing, and health care use).

RESUMEN

Adverse childhood experiences (ACEs) are a well-documented HIV-risk factor, but less is known about the relationship between ACEs and different HIV testing strategies. This study used data from an LGBTQ + community health assessment, that was part of a multi-staged community-based participatory research project in San Antonio, Texas. Overall, 464 young men who have sex with men (YMSM; < 36-years-old) completed an online, cross-sectional survey that included questions about ACEs and HIV testing behavior. An association between increased ACEs exposure and the odds of clinic-based testing and HIVST HIV significantly decreased relative to never testing for HIV. Additionally, greater ACEs exposure was significantly associated with increased odds of reporting community-based testing (AOR = 1.09, 95% CI = 1.00, 1.20) and significantly reduced odds of HIV self-testing (AOR = 0.72, 95% CI = 0.63, 0.82) compared to clinic-based testing. Cumulative ACEs exposure is important in understanding HIV testing behaviors in YMSM and should be considered when developing HIV testing programs.

RESUMEN

INTRODUCTION: This study aimed to investigate sexual orientation disclosure and mental health among young men who have sex with men (YMSMs). To this end, we constructed a chained multimediator model of sexual minority stigma, sexual minority identity, social support, and resilience, with the moderator of sexual orientation disclosure. METHODS: We conducted a cross-sectional survey of 345 YMSMs in Nanning, China. Bivariate analysis was used to evaluate factors associated with sexual orientation disclosure. Sexual minority stigma was used to predict identity, with social support as the step 1 mediator and resilience as the step 2 mediator. Sexual minority identity was analyzed using a chained moderated mediation model; sexual orientation disclosure was included as a moderator in all models to control its confounding effect. RESULTS: The average age of YMSMs was 20.0 ± 1.3 years. Bivariate analysis indicated that YMSMs who disclosed sexual orientation may have experienced less stigma (15.49 ± 3.02 vs 16.21 ± 2.74), obtained more social support (65.98 ± 11.18 vs 63.19 ± 11.13), had strong psychological resilience (37.40 ± 8.57 vs 35.39 ± 7.73), and had a more positive self-identity (104.12 ± 21.10 vs 95.35 ± 16.67); differences between subgroups were statistically significant (p < 0.05). Sexual minority stigma, perceived stigma, and enacted stigma were significantly associated with social support and resilience. The association between sexual minority stigma and sexual minority identity was significantly mediated by social support (indirect effect [95% CI] = - 3.307 [- 4.782, - 1.907]). Resilience significantly mediated the same association for identity (- 2.544 [- 4.052, - 1.114]). The chained relationship from sexual minority stigma to social support, resilience, and identity was also significant, with an indirect effect of - 0.404 [- 0.621, - 0.249]. CONCLUSION: Among YMSMs in China, sexual minority stigma affects sexual minority identity through social support and resilience. Given the psychological effects of stigma, social support and resilience must be considered to better promote positive self-identity and mental health among YMSMs.

RESUMEN

Background: Young men who have sex with men (YMSM) are at high risk of HIV infection that accounts for an increasing proportion of new human immunodeficiency virus (HIV) infections in China. However, little is known about the trajectories of sexual risk behaviors in this population. The study aimed to investigate longitudinal patterns of sexual risk behaviors among YMSM in China. Methods: Study data were collected from a prospective cohort study among 460 YMSM from 2017 to 2020. Based on the predicted HIV infection risk scores, distinct sexual risk behaviors trajectories of YMSM were estimated and plotted using the group-based censored normal model to identify the predictors of trajectories change over time. Results: Three sexual risk behaviors trajectories were identified: a decreasing low-risk group (7.6%), an intermediate-risk group (67.4%), and an ascending high-risk group (25.0%).Compared to the decreasing low-risk group, intermediate-risk group membership was associated with being from rural areas, current smoker and higher depressive symptoms; ascending high-risk group membership was associated with an education level of high school or lower, being from rural areas, younger age at sex debut with a man, current smoker, higher depressive symptoms and sexual minority stress. Conclusions: Sexual risk behaviors among YMSM changed over time within different trajectories. Identifying YMSM belonging to high-risk trajectories before HIV infection is vital for the intervention and may reduce HIV transmission.

RESUMEN

Improving access to HIV testing among youth at high risk is essential for reaching those who are most at risk for HIV and least likely to access health care services. This study evaluates the usability of mLab, an app with image-processing feature that analyzes photos of OraQuick HIV self-tests and provides real-time, personalized feedback. mLab includes HIV prevention information, testing reminders, and instructions. It was developed through iterative feedback with a youth advisory board (N = 8). The final design underwent heuristic (N = 5) and end-user testing (N = 20). Experts rated mLab following Nielsen's heuristic checklist. End-users used the Health Information Technology Usability Evaluation Scale. While there were some usability problems, overall study participants found mLab useful and user-friendly. This study provides important insights into using a mobile app with imaging for interpreting HIV test results with the goal of improving HIV testing and prevention in populations at high risk.

RESUMEN

OBJECTIVE: The widespread and frequent use of mobile technology among adolescents, including sexual minority adolescents, presents an opportunity for the development of mobile health (mHealth) technology to combat the continuing HIV epidemic among young men who have sex with men (YMSM). We analyzed perceptions of the quality and impact of an HIV prevention mobile app on sexual risk reduction among YMSM. METHODS: Participants were recruited from a larger randomized controlled trial of the MyPEEPS Mobile app among YMSM aged 13-18 years. Data were collected via semi-structured interviews to assess quality and user satisfaction with MyPEEPS Mobile app using analysis informed by the Information Systems Success framework. Interview data were transcribed verbatim and analyzed using six themes: information quality, net benefit, user satisfaction, product quality, service quality, and health care barriers. RESULTS: Interviews were conducted with 40 YMSM (45% Hispanic; 80% non-White; 88% non-rural resident; 28% aged 17 years). Participants' responses indicated that information quality was high, reporting that the app information was concise, easy to understand, useful, and relevant to their life. The net benefits were stated as improvements in their decision-making skills, health behaviors, communication skills with partner(s), and increased knowledge of HIV risk. There was general user satisfaction and enjoyment when using the app, although most of the participants did not intend to reuse the app unless new activities were added. Participants expressed that the product quality of the app was good due to its personalization, representation of the LGBTQIA + community, and user-friendly interface. Although no major technical issues were reported, participants suggested that adaption to a native app, rather than a web app, would improve service quality through faster loading speed. Participants also identified some health care barriers that were minimized by app use. CONCLUSIONS: The MyPEEPS Mobile app is a well received, functional, and entertaining mHealth HIV prevention tool that may improve HIV prevention skills and reduce HIV risk among YMSM.

RESUMEN

BACKGROUND: Young men who have sex with men (YMSM) are disproportionately impacted by HIV and other sexually transmitted infections (STIs) in the United States (US) and have low rates of HIV/STI testing. Provision of HIV self-testing and STI self-collection can increase testing rates, and access to these kits through mobile applications (apps) could help facilitate YMSM using HIV self-testing and STI self-collection. METHODS: Data for this study comes from two pilot randomized controlled trials (RCTs) of mobile apps within the Adolescent Trials Network-LYNX and MyChoices-aimed to increase HIV/STI testing among YMSM (age 15-24) who had not recently tested for HIV and were at high risk for HIV acquisition across five US cities. Both apps include the ability to order a HIV self-test with rapid results and a kit for STI self-collection and mailing of samples for syphilis, gonorrhea and chlamydia to a lab for testing. Using assessments of app users (n=80) at pre-randomization and at 3- and 6-months post-randomization and online interview data from a purposive sample of app users (n=37), we report on experiences and lessons learned with HIV self-testing and STI self-collection kits ordered via the apps. RESULTS: Participants were on average 20.7 years of age (SD =2.4), and 49% were non-White or multiple race/ethnicity. Sixty-three percent had a prior HIV test. Over half (58%) had a prior STI test, but only 3% had tested within the past 3 months. Nearly two-thirds ordered an HIV self-testing kit; of whom, 75% reported using at least one self-test kit over the study period. STI self-collection kit ordering rates were also high (54%); however, STI self-collection kit return rates were lower (13%), but with a high positivity rate (5.3%). Both HIV self-testing and STI self-collection kits were highly acceptable, and 87% reported that it was extremely/very helpful to be able to order these kits through the apps. The most common reason for not ordering the HIV/STI kits was preferring to test at a clinic. In interviews, participants expressed feeling empowered by being able to test at home; however, they also raised concerns around STI sample collection. CONCLUSIONS: HIV self-testing and STI self-collection kit ordering via mobile apps is feasible, acceptable and may show promise in increasing testing rates among YMSM. The LYNX and MyChoices apps are currently being tested in a full-scale efficacy trial, and if successful, these innovative mobile apps could be scaled up to efficiently increase HIV/STI testing among youth across the US.
