Pre-exposure prophylaxis (PrEP) is a lifesaving medical intervention that protects against human immunodeficiency virus (HIV), but to date, PrEP uptake has been limited. PrEP utilization and adherence among youth, including stigmatized and highly vulnerable young sexual and gender minorities, have been exceptionally low across all regions, leading to preventable HIV transmission. Considering the scientific value of measuring and understanding predictors or associations of PrEP adherence, our study team validated two scales: a PrEP Difficulties Scale and a PrEP Confidence Scale tested within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minorities who were prescribed PrEP across nine domestic sites were evaluated (

Scaling up use of Pre-Exposure Prophylaxis (PrEP) among young men who have sex with men and transgender women (YMSM/TGW) is a critical part of the

Black men who have sex with men (BMSM) face disproportionately higher risks for adverse sexual health outcomes compared to their non-Hispanic White counterparts. This disparity can be attributable to overlapping and intersecting risk factors at the individual and structural levels and can be understood through syndemic theory. Using longitudinal data from the HealthMPowerment trial (n = 363), six conditions related to stigma syndemics were indexed as a cumulative risk score: high alcohol use, polydrug use, depression and anxiety symptomology, and experiences of racism and sexual minority stigma. Using Poisson regression, we found a positive association between baseline risk scores and sexual risk behavior (b: 0.32, SE: 0.03, p 0.001). Using a Generalized Estimating Equation, we also found a 0.23 decrease in the within-participant risk scores at 3-month follow-up (SE: 0.10, p 0.020). Future work examining how care and prevention trials improve health outcomes in this population is needed.

Background Almost all adolescents aged 13 to 17 in the United States have access to a smartphone. While studies have commonly assessed the feasibility or usability of mobile health applications (“apps”), few have examined the acceptability of apps—whether individuals would actually use these health apps in their everyday lives—among adolescent populations. Objectives This qualitative study aims to understand how adolescents assess the acceptability of health apps in the context of their everyday lives. Methods Nineteen adolescents in grades 7 through 9 were asked to download a health app before participating in two semi-structured interviews 2 weeks apart. Seven domains from the Theoretical Framework of Acceptability were assessed: affective attitude, burden, ethicality, intervention coherence, opportunity costs, perceived effectiveness, and self-efficacy. A Grounded Theory approach was used to analyze data. Results The seven acceptability domains plus two additional themes, intervention expectations (what adolescents anticipated given their experiences with other apps) and peer norms (friends' beliefs and attitudes toward the intervention's health topic), were salient. Conclusion These nine domains of acceptability are relevant to adolescents and should be assessed during health app development by app developers and health researchers to improve adolescents' acceptability perceptions and potentially increase app usage.

Summary Mental health problems, including anxiety and depression, are a common comorbidity among gay, bisexual and other men who have sex with men (GBMSM) living with HIV. Informed by social support theory, health navigation is a strengths-based intervention that has been demonstrated to improve HIV care outcomes. The purpose of this study was to explore how health navigation influences the mental health of GBMSM living with HIV. We analyzed longitudinal qualitative in-depth interviews conducted with GBMSM (n = 29) in a 12-month multi-component intervention to improve HIV care outcomes, including health navigation. We used narrative and thematic analytic approaches to identify salient themes, including if and how themes changed over time. Participants described that navigator support helped them maintain good mental health, prevent crises and respond to crises. Navigator support included providing motivational messaging, facilitating participants’ control over their health and improving access to care, which aided with supporting mental health. Navigators also responded to acute crises by providing guidance for those newly diagnosed with HIV and support for those experiencing critical life events. Participants emphasized the importance of feeling heard and valued by their navigators and gaining hope for the future as key to their wellbeing. In conclusion, health navigation may be an effective intervention for promoting mental health among GBMSM living with HIV. Additional research is needed to examine mediating pathways between navigation and mental health, including informational support, or if navigator support moderates the relationship between stressors and mental health outcomes for GBMSM.

Background Interventions for increasing the uptake of COVID-19 vaccination among Black young adults are central to ending the pandemic. Black young adults experience harms from structural forces, such as racism and stigma, that reduce receptivity to traditional public health messaging due to skepticism and distrust. As such, Black young adults continue to represent a priority population on which to focus efforts for promoting COVID-19 vaccine uptake. Objective In aims 1 and 2, the Tough Talks digital health intervention for HIV disclosure will be adapted to address COVID-19 vaccine hesitancy and tailored to the experiences of Black young adults in the southern United States (Tough Talks for COVID-19). In aim 3, the newly adapted Tough Talks for COVID-19 digital health intervention will be tested across the following three southern states: Alabama, Georgia, and North Carolina. Methods Our innovative digital health intervention study will include qualitative and quantitative assessments. A unique combination of methodological techniques, including web-based surveys, choose-your-own-adventures, digital storytelling, user acceptability testing, and community-based participatory approaches, will culminate in a 2-arm hybrid type 1 effectiveness implementation randomized controlled trial, wherein participants will be randomized to the Tough Talks for COVID-19 intervention arm or a standard-of-care control condition (N=360). Logistic regression will be used to determine the effect of the treatment arm on the probability of vaccination uptake (primary COVID-19 vaccine series or recommended boosters). Concurrently, the inner and outer contexts of implementation will be ascertained and catalogued to inform future scale-up. Florida State University’s institutional review board approved the study (STUDY00003617). Results Our study was funded at the end of April 2021. Aim 1 data collection concluded in early 2022. The entire study is expected to conclude in January 2025. Conclusions If effective, our digital health intervention will be poised for broad, rapid dissemination to reduce COVID-19 mortality among unvaccinated Black young adults in the southern United States. Our findings will have the potential to inform efforts that seek to address medical mistrust through participatory approaches. The lessons learned from the conduct of our study could be instrumental in improving health care engagement among Black young adults for several critical areas that disproportionately harm this community, such as tobacco control and diabetes prevention.

IntroductionLittle is known about when youth living with HIV (YLHIV) are most susceptible to disengagement from HIV care. The longitudinal HIV care continuum is an underutilized tool that can provide a holistic understanding of population-level HIV care trajectories and be used to compare treatment outcomes across groups. We aimed to explore effects of the Universal Test and Treat policy (UTT) on longitudinal care outcomes among South African youth living with HIV (YLHIV) and identify temporally precise opportunities for re-engaging this priority population.MethodsUsing medical record and census data, we conducted a retrospective cohort study among youth aged 18-24 newly diagnosed with HIV between August 2015 and December 2018 in nine health care facilities in rural South Africa. We used weighted Fine and Grey sub-distribution proportional hazards models to characterize longitudinal care continuum outcomes in the population overall and stratified by treatment era of diagnosis. We estimated the proportion of individuals in each stage of the continuum over time and the mean time spent in each stage in the first year following diagnosis. Estimates for the two groups were compared using differences (diagnosis pre-UTT=referent).ResultsA total of 420 YLHIV were included. By the end of the first year following diagnosis, just 23% of individuals had no 90-or-more-day lapse in care and were virally suppressed. Those diagnosed in the UTT era spent less time as ART-naïve (mean difference=-19.3 days; 95% CI: - 27.7, -10.9) and more time virally suppressed (mean difference=17.7; 95% CI: 1.0, 34.4) compared to those diagnosed pre-UTT adoption. Most individuals who were diagnosed in the UTT era and experienced a 90-or-more-day lapse in care disengaged between diagnosis and linkage to care or ART initiation and viral suppression.ConclusionsImplementation of UTT yielded modest improvements in time spent on ART and virally suppressed among South African YLHIV. However, meeting UNAIDS’ 95-95-95 targets remains a challenge in this priority population. Retention in care and re-engagement interventions that can be implemented between diagnosis and linkage to care (e.g., longitudinal counseling following diagnosis) or ART initiation and viral suppression may be particularly important to improving treatment outcomes among South African YLHIV.

To date, there are no established scales to assess PrEP stigma among youth. We validated the Youth PrEP Stigma Scale within the Adolescent Trials Network P3 study (2019-2021). Data from sexual and gender minority youth (16-24 years) who were prescribed PrEP across nine domestic sites were evaluated (N = 235). Descriptive statistics, exploratory factor analysis, and correlation coefficients are reported. Results yielded a three-factor solution (PrEP Disapproval by Others, Enacted PrEP Stigma, and PrEP User Stereotypes) with strong factor loadings and Cronbach's alphas ranging from 0.83 to 0.90, suggesting excellent internal consistency. Correlations between this Scale, anticipated HIV stigma, perceived HIV risk, and disclosure of sexual identity were significant, indicating potential for robust application. Given the persistence of HIV infections among youth, stigma as a barrier to prevention, and expansion of PrEP modalities, the Youth PrEP Stigma Scale could enhance intervention and mechanistic research among youth at elevated risk for HIV acquisition.Hasta la fecha, no existen escalas establecidas para evaluar el estigma de la PrEP entre los jóvenes. Validamos la Escala de estigma de la PrEP para jóvenes dentro del estudio P3 de la Red de ensayos para adolescentes (2019–2021). Se evaluaron los datos de jóvenes de minorías sexuales y de género (16–24 años) a quienes se les recetó PrEP en nueve sitios domésticos (N = 235). Se informan estadísticas descriptivas, análisis factorial exploratorio y coeficientes de correlación. Los resultados arrojaron una solución de tres factores (desaprobación de PrEP por parte de otros, estigma de PrEP promulgado y estereotipos de usuarios de PrEP) con fuertes cargas factoriales y alfas de Cronbach que oscilan entre 0.83 y 0.90, lo que sugiere una excelente consistencia interna. Las correlaciones entre esta Escala, el estigma anticipado del VIH, el riesgo percibido del VIH y la divulgación de la identidad sexual fueron significativas, lo que indica un potencial para una aplicación sólida. Dada la persistencia de las infecciones por el VIH entre los jóvenes, el estigma como una barrera para la prevención y la expansión de las modalidades de PrEP, la Escala de estigma de la PrEP para jóvenes podría mejorar la intervención y la investigación mecánica entre los jóvenes con un riesgo elevado de contraer el VIH.

Interactive stories are a relatively newer form of storytelling with great potential to correct misinformation while increasing self-efficacy, which is crucial to vaccine acceptance. To address COVID-19 vaccine hesitancy and medical mistrust in young Black adults (BYA), we sought to adapt a pre-existing application ("app"; Tough Talks) designed to address HIV disclosure decision-making through choose-your-own adventure (CYOA) narratives and other activities. The adapted app (Tough Talks - COVID) uses a similar approach to situate COVID-19 vaccination decision-making within social contexts and to encourage greater deliberation about decisions. To inform content for the CYOA narratives, we conducted an online survey that was used to elicit the behavioral, cognitive, and environmental determinants influencing COVID-19 vaccine hesitancy among 150 BYA (ages 18-29) in Georgia, Alabama, and North Carolina. The survey included scenario questions that were developed with input from a youth advisory board to understand responses to peer and family influences. In two scenarios that involved discussions with family and friends about vaccination status, most respondents chose to be honest about their vaccination status. However, vaccinated individuals perceived more social pressure and stigma about not being vaccinated than unvaccinated respondents who were not as motivated by social pressure. Personal choice/agency in the face of perceived vaccine risks was a more common theme for unvaccinated respondents. Results suggest that relying on changing social norms alone may not impact barriers to vaccination in unvaccinated young adults without also addressing other barriers to vaccination such as concerns about autonomy and vaccine safety. Based on these findings, CYOA narratives in the app were adapted to include discussions with family and friends but also to touch on themes of personal choice as well as other topics that influence behaviors besides norms such as safety, side effects, and risk of COVID-19 in an evolving pandemic.

OBJECTIVE To examine how neighborhood characteristics are associated with health outcomes among older adults with osteoarthritis. METHODS In multilevel, cross-sectional, and longitudinal analyses we examined whether 4 neighborhood characteristics were associated with depressive symptoms and reported knee impact scores, and whether the neighborhood characteristics interacted with race/ethnicity among older adults with radiographic knee osteoarthritis (n = 656 for cross-sectional analyses and n = 434 for longitudinal analyses). The data came from the Johnston County Osteoarthritis Project, a prospective cohort study in North Carolina designed to examine risk factors for osteoarthritis. RESULTS Although few longitudinal associations were found, cross-sectional results suggested that greater perceived neighborhood social cohesion (B = -0.04, P < 0.001) and perceived neighborhood resources for physical activity and walking (B = -0.03, P < 0.001) were associated with fewer depressive symptoms, and that greater perceived neighborhood resources for physical activity and walking were associated with higher (better) knee impact scores (B = 0.48, P = 0.008). We also observed 2 significant interactions among neighborhood characteristics and race/ethnicity related to depressive symptoms (P < 0.01); for African American adults, greater perceived neighborhood resources for physical activity and walking were associated with fewer depressive symptoms (B = -0.03, P < 0.001), but for White adults, greater perceived neighborhood safety was associated with fewer depressive symptoms (B = -0.04, P = 0.003). CONCLUSION In a sample of older adults with radiographic knee osteoarthritis, neighborhood context mattered, but in nuanced ways. Interventions aiming to improve mental and physical functioning of older adults with knee osteoarthritis can look to this study as evidence for the importance of neighborhood characteristics.

BACKGROUND Few studies have focused on attitudes towards novel coronavirus 2019 (COVID-19) vaccination among Black or African American young adults (BYA) in the Southern United States (US), despite high levels of infection in this population. OBJECTIVE To understand this gap, we conducted an online survey to explore beliefs and experiences related to COVID-19 vaccination among BYA (ages 18-29) in three southern states. METHODS We recruited 150 BYA to participate in an online survey as formative research for an intervention to address vaccine hesitancy/skepticism in Alabama, Georgia, and North Carolina between September 22, 2021, and November 18, 2021. Participants were recruited through social media ads on Facebook, Twitter, Instagram, and YouTube. Additionally, we distributed information about the survey through national organizations working with BYA, our community partners and network collaborations. We used validated measures from prior surveys on COVID-19 vaccination. RESULTS Less than half of vaccinated respondents planned to get a booster shot (47%, n=71) and 14% (n=28) had not received any doses of the COVID-19 vaccine. Half of unvaccinated respondents (50%, n=14) reported they wanted to wait longer before getting vaccinated. Motivators to get vaccinated were similar between unvaccinated and vaccinated respondents (e.g., if required, to protect the health of others); but the main motivator for those vaccinated was to protect one’s own health. Among unvaccinated individuals, reasons for not receiving the COVID-19 vaccine included concern about vaccine side effects (54%) and mistrust of vaccine safety (46%), of effectiveness (43%), and of the government’s involvement with vaccines (43%). Experiences of discrimination (40%) and mistrust of vaccines (36%) were common even among the vaccinated population. Among all respondents, those who said they would be motivated to get vaccinated if it was required for school, work, or travel, were more likely to endorse negative beliefs about vaccines compared to those motivated for other reasons. CONCLUSIONS Mistrust in COVID-19 vaccine safety and efficacy was common among this sample of BYA in the South, irrespective of vaccination status. Other motivators such as safety of family and community and vaccination requirements may be able to tip the scales towards a decision to be vaccinated among those who are initially hesitant. However, it is unclear how vaccine requirements among BYA in the South affect trust in government or healthcare in the long-term. Interventions that include young Black adults in vaccination messaging and programs may consider more proactively addressing trust and countering misinformation.

Sexual empowerment represents an important HIV intervention strategy, yet limited attention has examined the multidimensional nature of sexual empowerment in prior studies. Using a sample (n = 465) of young Black men who have sex with men (MSM), we used confirmatory factor analysis (CFA) to test a multifactorial operationalization of sexual empowerment. CFA indicated that a bifactor model was best suited to characterize the sexual empowerment factor (SEF), suggesting that items for four sub-constructs (self-efficacy to refuse sexual behavior, emotional support, condom use self-efficacy, and social norms on condom use) contributed to their respective constructs, while also contributing to a latent sexual empowerment construct. We then examined the association between SEF and mental health outcomes (anxiety and depression symptoms) and safer sex intentions. SEF was negatively associated with mental health outcomes and positively associated with safer sex intentions. Ultimately, individuals with greater sexual empowerment might be better equipped to develop strategies to buffer their vulnerability to HIV. We discuss the implications of SEF as a bifactor during the design and evaluation of HIV risk-reduction interventions seeking to address sexual empowerment among MSM.

Biomedical advances in diagnostics, treatment and prevention increase the means available to reduce HIV transmission risk. Subsequent shifts in HIV status disclosure obligation and ethics may impact how those living with HIV view, enact and experience disclosure. We analysed focus group and interview data to explore how these changes are reflected in disclosure decision-making to sexual partners among young gay and bisexual men living with HIV in the USA. Three interrelated themes were identified: engaging with partners' varying HIV knowledge; attribution of blame; and negotiating disclosure-related harms. Participants experienced blame from partners that questioned the timing of HIV testing, status disclosure and sex events without regards for viral suppression or use of pre-exposure prophylaxis. Substantial HIV stigma was described in response to disclosure, mitigated in some cases by partners' higher HIV knowledge. Overall, an uneven diffusion of HIV treatment and prevention knowledge and continuing HIV stigma seemed to limit the translation of biomedical advances into improved disclosure experiences. Our findings suggest that young gay and bisexual men living with HIV may continue to perform much of the moral labour involved in disclosure by managing others' reactions, correcting inaccurate sexual health information, and negotiating the risks of disclosure-related harm.

Young Black gay and bisexual men who have sex with men experience stigma related to race, gender expression, sexuality and HIV status. Stigma impacts access to HIV care and prevention as well as interactions with healthcare providers. The amplification of stigma through popular media is under-researched in the health sciences. HealthMpowerment is a mobile phone optimised intervention to reduce sexual risk and support community-building for young Black gay and bisexual men (age 18-30). We analysed Forum conversations from 48 participants, 45.8% living with HIV. Of 322 stigma-relevant conversations, 18.9% referenced the media (e.g. television, news, social media) as a source of stigma. Forum conversations covered media representations of Black gay and bisexual men, media's influence on identity, and the creation of stigma by association with media representations. Cultural messages embedded in the media may accentuate stereotypes that influence perceptions of Black gay and bisexual men and disregard intersectional identities. HealthMpowerment provided a space to challenge stigmatising representations. Participants used HealthMpowerment to garner social support and celebrate positive media representations. Interventions for young Black gay and bisexual men should consider the influential role of media and include spaces for participants to process and address stigma.

INTRODUCTION: Young black men who have sex with men (YBMSM) are disproportionately affected by HIV. Intersectional stigmas are associated with increased HIV vulnerability, and worse outcomes for YBMSM with HIV. YBMSM find sex partners via sexual networking apps, but stigma on apps has been poorly studied. METHODS: We conducted cross-sectional analysis of 324 YBMSM seeking sex partners via apps to assess stigma experiences in eight dimensions compared to non-users (N=150). We conducted detailed stratified analyses to identify granular stigma data. RESULTS: App users had higher median scores than non-users in perceived HIV discrimination, perceived HIV stigma, experienced sexual minority stigma, racial discrimination, and perceived homophobia. DISCUSSION: We demonstrate higher levels of intersectional stigmas among app users than non-users, but did not find an overall increase in stigma with increasing app use. Considering the prominent role of apps in YBMSM sexual networking, interventions that reduce stigma on apps are needed.

Background Transgender and gender diverse individuals often face structural barriers to health care because of their gender minority status. The aim of this study was to examine the association between gender minority stress and access to specific health care services among transgender women and transfeminine people in China. Methods This multicenter cross-sectional study recruited participants between January 1st and June 30th 2020. Eligible participants were 18 years or older, assigned male at birth, not currently identifying as male, and living in China. Gender minority stress was measured using 45 items adapted from validated subscales. We examined access to health care services and interventions relevant to transgender and gender diverse people, including gender affirming interventions (hormones, surgeries), human immunodeficiency virus (HIV) and sexually transmitted infections (STIs) testing, pre-exposure prophylaxis (PrEP) and post-exposure prophylaxis (PEP). Multivariable regression was used to measure correlations between gender minority stress and access to health care service. Results Three hundred and twenty-four people completed a survey and data from 277 (85.5%) people were analyzed. The mean age was 29 years old (standard deviation [SD] = 8). Participants used hormones (118/277, 42.6%), gender affirming surgery (26/277, 9.4%), HIV testing (220/277, 79.4%), STI testing (132/277, 47.7%), PrEP (24/276, 8.7%), and PEP (29/267, 10.9%). Using gender affirming hormones was associated with higher levels of discrimination (adjusted odds ratio [aOR] 1.41, 95% confidence interval [CI] 1.17–1.70) and internalized transphobia (aOR 1.06, 95%CI 1.00–1.12). STI testing was associated with lower levels of internalized transphobia (aOR 0.91, 95%CI 0.84–0.98). Conclusions Our data suggest that gender minority stress is closely related to using health services. Stigma reduction interventions and gender-affirming medical support are needed to improve transgender health.

HIV incidence among young men who have sex with men (YMSM) is disproportionally high. Youth living with HIV demonstrate low rates of sustained virologic suppression (VS). Epic Allies, a theory-based behavioral intervention mobile app, utilizes self-management tools, gamification, and social support to improve engagement in care and antiretroviral adherence among YMSM living with HIV. A two-arm individually randomized-controlled trial enrolled 146 participants aged 16 to 24 years old to test the efficacy of Epic Allies to achieve VS. Both study arms showed improved VS at 26-weeks (62.9% intervention; 73.5% control; ARR = 0.93 (95% CI 0.73, 1.18)) and antiretroviral adherence; intervention effects were amplified in regular app users. Issues with recruitment and app usage metrics limit the ability to definitively say that the app was effective in causing behavior changes resulting in improved health outcomes. (ClinicalTrials.gov Identifier: NCT02782130).

Understanding how Chinese gay, bisexual, and other men who have sex with men (GBMSM) cope with HIV care-related stressors could improve their care engagement. Qualitative semistructured interviews were conducted with 30 GBMSM living with HIV recruited through clinics and a community-based organization (CBO) in Chengdu, China. Interviews focused on treatment-related stress, coping strategies, social support, and well-being. Half reported symptoms consistent with mild or moderate depression as measured by the PHQ-9 scale. HIV care-related stressors included side effects, difficulty with adherence, and fear of drug resistance. Challenges to coping include navigating contradictory information about HIV and treatment, experiencing stigma and discrimination within medical and nonmedical settings, and managing financial concerns. CBOs, peer groups, and providers were salient sources of social support benefitting coping. To improve sustained HIV care that meets the needs of Chinese GBMSM living with HIV, tailored interventions that address the above-mentioned stressors and coping challenges are likely needed.

Introduction Youth engagement in HIV research is generally recognized as essential, but often neglected or minimally implemented in practice. Engagement is a process of working collaboratively with diverse groups of people to address common issues. We conducted a scoping review of youth HIV prevention interventions in sub‐Saharan Africa to identify and categorize forms and levels of youth engagement across the lifespan of intervention research. Methods We followed Arksey and O'Malley's framework for organizing a scoping review. We searched seven databases for related articles on identified intervention studies through May 28th 2020. Included studies focused on youth (10 to 24 years old) HIV prevention interventions in sub‐Saharan Africa. Two reviewers independently examined citations and full manuscripts for inclusion. Data were extracted on study characteristics, location, description of youth engagement and extent of engagement. Youth engagement approaches were categorized based on Hart’s ladder as substantial engagement (strong youth decision‐making power), moderate engagement (shared decision making with adults), minimal engagement (no youth decision‐making power) or no engagement. Results We identified 3149 citations and included 112 studies reporting on 74 unique HIV interventions. Twenty‐two interventions were in low‐income countries, 49 in middle‐income countries, and three were in both. Overall, only nine interventions (12%) had substantial or moderate youth engagement, two‐thirds (48, 65%) had minimal youth engagement and 17 interventions (23%) had no youth engagement. We also identified specific engagement strategies (e.g. youth‐led research, crowdsourcing) that were feasible in multiple settings and resulted in substantial engagement. Conclusions We found limited youth engagement in youth HIV prevention intervention studies in sub‐Saharan Africa. However, several activities resulted in substantial youth engagement and could be relevant in many low‐and‐middle‐income‐country (LMIC) settings.

Background Young people in low- and middle-income countries are often neglected in designing youth-friendly health services, especially HIV testing and preventive services. Designathons, which are time-bounded co-creation events where individuals gather in teams to develop solutions to a problem, could promote youth participation and ownership of health services. Objective The purpose of this study is to examine youth participation in a designathon to create youth-friendly health services in Nigeria. Methods Our designathon was based on crowdsourcing principles and informed by a human-centered design approach. The designathon included an open call for Nigerian youths between 14 and 24 years to share ideas on how to promote uptake of HIV self-testing services and a three-day sprint event that brought together diverse teams to develop strategies enhancing linkage to care. Teams pitched their solutions to a panel of five independent experts who scored ideas based on the desirability, feasibility, potential impact, and teamwork. We used descriptive statistics to summarize participants’ demographics and conducted a content analysis to synthesize themes from youth proposals. Results Nine hundred seventy-six youth across Nigeria applied to join the designathon. Forty-eight youth in 13 teams participated in the designathon with a median age of 20 years (IQR: 17–22]. Boys and young men were 48.5% (446/919) of the total applicants, 62.5% (30/48) of the designathon participants, and 63.6% (7/11) of the finalists. Students, from all educational levels, represented 91.2% (841/922) of the total applicants, 88.4% (38/43) of the designathon participants, and 90.0% (9/10) of the finalists. About twenty-three percent (3/13) of the final proposals were top ranked. The three finalist approaches to optimize youth-friendly health services centered on decentralizing service delivery to young people through mobile health technologies, use of mobile tents, or peer support services. Conclusions Our open call engaged diverse groups of Nigerian youth, including young women and students. Our data suggest that designathons may be useful for developing tailored youth-friendly health services. Further research is needed to understand the designathon process and the effectiveness of the finalist submissions.

RATIONALE. Historic and present-day racism and inequity in the United States (U.S.) have resulted in diminished trust in health care among many populations. A key barrier to improving trust in health care is a dearth of well-validated measures appropriate for diverse populations. Indeed, systematic reviews indicate a need to develop and test updated trust measures that are multidimensional and inclusive of relevant domains (e.g., fairness). OBJECTIVE. We developed three trust measures: the Trust in My Doctor (T-MD), Trust in Doctors in General (T-DiG), and Trust in the Health Care Team (T-HCT) scales. METHODS. After developing an initial item pool, expert reviewers (n=6) provided feedback on the face validity of each scale. We conducted cognitive interviews (n=21) with a convenience sample of adults to ensure items were interpreted as intended. In 2020, we administered an online survey to a convenience sample of U.S. adults recruited through the Qualtrics Panel (n=801) to assess scale reliability and validity. RESULTS. Exploratory and confirmatory factor analyses indicated acceptable model fit for second order latent factor models for each scale (root mean square error of approximation

IntroductionEmtricitabine-Tenofovir was officially approved as the first medicine for HIV pre-exposure prophylaxis (PrEP) in China on August 11, 2020. The large number of key populations who would benefit from PrEP in the context of limited health system capacity and public awareness will pose challenges for timely PrEP scale-up. This suggests an urgent need for innovative and accessible intervention tools for promoting PrEP. Our overall goal is to develop and pilot test a theory-informed, tailored mobile phone intervention to increase engagement in PrEP education and initiation among Chinese gay, bisexual, and other men who have sex with men (GBMSM). We also aim to generate hypotheses of potential behavioral pathways to PrEP uptake among Chinese GBMSM.Methods and analysisThis two-phase study includes a formative assessment (Phase 1) using in-depth interviews (N=30) and a 12-week experimental pilot study (Phase 2) using a two-arm randomized controlled trial design (N=60). The primary intervention is delivered through a WeChat-based mini-app (a program built into a Chinese multipurpose social media application) developed by young GBMSM from a 2019 crowdsourcing hackathon. This participatory event brought together GBMSM, tech experts, health professionals, and other key stakeholders. This study will further investigate the specific needs and concerns among GBMSM in terms of using PrEP as an HIV prevention strategy, how their concerns and PrEP use behaviors may change with exposure to the mini-app intervention at 8-week and 12-week follow-up, and how we can further refine this intervention tool to better meet GBMSM ‘s needs for broader implementation.Ethics and disseminationThis study and its protocols have been reviewed and approved by the Institutional Review Boards of the University of North Carolina at Chapel Hill, USA (IRB#19-3481), the Guangdong Provincial Dermatology Hospital, China (IRB#2020031), and the Guangzhou Eighth People ‘s Hospital, China (IRB#202022155). Study staff will work with local GBMSM community-based organizations to disseminate the study results to participants and the community via social media, offline workshops, and journal publication. This research addresses a critical need as GBMSM bear a disproportionate burden of HIV infections in China and remain underserved in the healthcare system.Trial RegistrationThe study was registered on clinicaltrials.gov (Trial#: NCT04426656) on June 11, 2020. https://clinicaltrials.gov/ct2/show/NCT04426656. Prospectively registered.

Sexual empowerment is a key strategy in HIV prevention intervention design, yet its measurement has been conceptualized as homogeneous. To date, no studies have examined whether young Black men who have sex with men (YBMSM) exhibit heterogeneity across sexual empowerment. Using baseline data from a randomized controlled trial (N = 275, HIV-negative YBMSM), we classified YBMSM into sexual empowerment profiles based on five indicators using a latent profile analysis and assessed the associations between the sexual empowerment profiles and stigma-related experiences using multinomial logistic regression. Three profiles were identified: psychologically empowered with safer sex intentions (profile 1); psychologically disempowered with safer sex intentions (profile 2); and psychologically disempowered without safer sex intentions (profile 3). YBMSM reporting fewer stigma-related experiences were more likely to be profile 1 than profile 2 and profile 3. To empower YBMSM, interventions based on sexual empowerment profile targeting the psychological/behavioral aspects of empowerment and addressing stigma are needed.

Introduction Crowdsourcing, a participatory approach to solicit ideas from a large group of diverse individuals, provides an opportunity to nurture youth participation in HIV self-testing service design. The objective of this study was to describe the responses to a crowdsourcing contest aimed at soliciting ideas on how to promote HIV self-testing (HIVST) among young people in Nigeria. Methods The "4 Youth by Youth" HIV Self-Testing Crowdsourcing contest was an online and off-line contest that asked Nigerian youth (10-24 years old) for ideas in response to the following: How might we promote HIVST among young people in Nigeria? All data were collected and analyzed between October 2018, and June 2019. Ideas and perceptions generated from the crowdsourcing contest were qualitatively analyzed using thematic content analysis. Specifically, four reviewers analyzed whether the ideas generated were desirable (appealing to young people), feasible (easy to implement) and impactful (will significantly influence HIVST uptake among young people). Results A total of 903 entries were received in response to the contest prompt. Participants submitted entries in various forms: online form (39.7%), offline Dropbox (44.6%), email (6.1%) and WhatsApp (9.7%). Of the total entries, 85% (n = 769/903) entries were eligible and were scored as having either high, moderate or low level of feasibility, impact and desirability, on a 3-point Likert scale. A significant portion of the entries were given a score of 3 for feasibility (4.9%), desirability (7.1%), impact (3.0%) or a total overall score of 7 or more (8.2%). The three main themes that emerged from the entries include:1) Peer-to-peer distribution and leveraging on existing infrastructures 2) Youth-Oriented Branding of the HIVST Kit 3) Mobile platforms and social media technology. Conclusion The "4 Youth by Youth" Self-Testing contest engaged a broad audience of young people to generate ideas and perspectives on how to promote HIVST. This process informed the development of youth innovated implementation strategies to increase uptake of HIVST among adolescents and youth at risk for HIV.

HIV self-testing (HIVST) allows individuals to interpret and report their own test results, thus decentralizing testing. Yet, this decentralization can make it difficult to verify self-testing results, which is important for linkage to care and surveillance. The aim of this systematic review is to summarize methods for verifying HIVST use and results. We followed guidance from the Cochrane Handbook 5.1 on systematic reviews. We searched four journal databases (PubMed, Embase, Scopus, and Cochrane Library), one clinical trials database (ClinicalTrials.gov), two conference abstract databases (International AIDS Society and Conference on Retroviruses and Opportunistic Infections) and one gray literature database (OpenGrey). We included studies that verified opening of kits or test results. Two researchers independently screened articles and extracted data regarding HIVST location, method of verification, who performed verification, proportion of results verified, and primary or secondary kit distribution. The search yielded 3853 unique citations, of which 40 contained information on HIVST verification and were included. Among these 40 studies, 13 were in high-income countries, 16 were in middle-income countries, and 11 were in low-income countries. Seventeen studies included key populations and two focused on youth. Three methods verified results: supervision by a health provider, returning used test kits, and electronic transmission of photographs. One method verified opening of kits using Bluetooth sensors. Although HIVST has increased worldwide, strategies to verify self-testing results remain limited. These findings suggest a need for additional innovative strategies for verifying HIVST use and results and linkage of self-testing results to surveillance and care systems.

HIV care in China is shifting toward a community-based model involving a wide range of stakeholders. We aimed to understand key stakeholders’ perceived challenges of providing high-quality care for men who have sex with men (MSM) living with HIV. In-depth interviews were conducted with a diverse sample of stakeholders (N = 17) in two Chinese cities, including providers, policymakers, and community workers. Interviews focused on stakeholders’ challenges in HIV-related work and perceived barriers for MSM in accessing and maintaining HIV care. Thematic analysis strategies were used. Three cross-cutting themes related to accessibility and quality of care (QoC) emerged. First, MSM- and HIV-related stigma were perceived to increase the risk of MSM dropping out of care. While acknowledging stigma, some providers also expressed discriminatory views such as stereotypes of the MSM community. Second, stakeholders expressed concerns about QoC including healthcare workforce shortages, limited training opportunities, and high work stress while facing increasingly unmet needs from clients. Third, stakeholders shared challenges in mobilizing community resources to expand HIV care including unclear division of responsibility and strict auditing. Supportive policies and resources may be needed to bolster China’s primary care workforce and MSM-competent care and, more broadly, high QoC for sexual and gender minority patients.

Few studies have documented the pathways through which individual level variables mediate the effects of neighborhoods on health. This study used structural equation modeling to examine if neighborhood characteristics are associated with depressive symptoms, and if so, what factors mediated these relationships. Cross-sectional data came from a sample of mostly rural, older adults in North Carolina (n = 1,558). Mediation analysis indicated that associations among neighborhood characteristics and depressive symptoms were mediated by loneliness (standardized indirect effect = -0.19, p 0.001), physical activity (standardized indirect effect = -0.01, p = 0.003), and perceived individual control (standardized indirect effect = -0.07, p = 0.02) with loneliness emerging as the strongest mediator. Monitoring such individual mediators in formative and process evaluations may increase the precision of neighborhood-based interventions and policies.

BACKGROUND: The World Health Organization recommends HIV self-testing (HIVST) as an additional approach to HIV testing and the Nigerian government is supportive of this policy recommendation. However, effectively increasing uptake and sustainability among Nigerian youth is unknown. The goal of this study is to conduct a full-powered type I hybrid effectiveness-implementation trial to test the effectiveness of youth-friendly implementation science strategies in increasing uptake and sustainability of HIVST led by and for Nigerian youth. METHODS: Our 4 Youth by Youth (4YBY) strategy combines four core elements: 1) HIVST bundle consisting of HIVST kits and photo verification system; 2) a participatory learning community; 3) peer to peer support and technical assistance; and 4) on-site supervision and performance feedback to improve uptake and sustainability of HIVST and enhance linkage to youth-friendly health clinics for confirmatory HIV testing where needed, sexually transmitted infection (STI) testing (i.e. syphilis, gonorrhea, chlamydia, and hepatitis, STI treatment, and PrEP referral. Utilizing a stepped-wedge, cluster-randomized controlled trial, a national cohort of youth aged 14–24 recruited from 32 local government areas across 14 states and four geo-political zones in Nigeria will receive the 4YBY implementation strategy. In addition, an economic evaluation will explore the incremental cost per quality adjusted life year gained. DISCUSSION: This study will add to the limited “how-to-do it literature” on implementation science strategies in a resource-limited setting targeting youth population traditionally underrepresented in implementation science literature. Study findings will also optimize uptake and sustainability of HIVST led by and for young people themselves. TRIAL REGISTRATION: This study is registered in ClinicalTrials.gov NCT04710784 (on January 15, 2021).

Overlapping stigmas related to sexual minority-, race/ethnicity-, and HIV-status pose barriers to HIV prevention and care and the creation of supportive social networks for young, Black, gay, bisexual, and other men who have sex with men (GBMSM). A risk-based approach to addressing the HIV epidemic focuses on what is lacking and reinforces negative stereotypes about already-marginalized populations. In contrast, a strengths-based approach builds on Black GBMSM's existing strengths, recognizing the remarkable ways in which they are overcoming barriers to HIV prevention and care. HealthMpowerment (HMP) is an online, mobile phone optimized intervention that aimed to reduce condomless anal intercourse and foster community among young Black GBMSM (age 18-30). Applying a resilience framework, we analyzed 322 conversations contributed by 48 HMP participants (22/48 living with HIV) on the intervention website. These conversations provided a unique opportunity to observe and analyze dynamic, interpersonal resilience processes shared in response to stigma, discrimination, and life challenges experienced by young Black GBMSM. We utilized an existing framework with four resilience processes and identified new subthemes that were displayed in these online interactions: (1) Exchanging social support occurred through sharing emotional and informational support. (2) Engaging in health-promoting cognitive processes appeared as reframing, self-acceptance, endorsing a positive outlook, and agency and taking responsibility for outcomes. (3) Enacting healthy behavioral practices clustered into modeling sex-positive norms, reducing the risk of acquiring or transmitting HIV, and living well with HIV. (4) Finally, empowering other gay and bisexual youth occurred through role modeling, promoting self-advocacy, and providing encouragement. Future online interventions could advance strengths-based approaches within HIV prevention and care by intentionally building on Black GBMSM's existing resilience processes. The accessibility and anonymity of online spaces may provide a particularly powerful intervention modality for amplifying resilience among young Black GBMSM.

HIV status disclosure is associated with increased social support and protective behaviors against HIV transmission. Yet disclosure poses significant challenges in the face of persistent societal stigma. Few interventions focus on decision-making, self-efficacy, and communication skills to support disclosing HIV status to an intimate partner. Virtual reality (VR) and artificial intelligence (AI) technologies offer powerful tools to address this gap. Informed by Social Cognitive Theory, we created the Tough Talks VR program for HIV-positive young men who have sex with men (YMSM) to practice status disclosure safely and confidentially. Fifty-eight YMSM (ages 18 – 30, 88% HIV-positive) contributed 132 disclosure dialogues to develop the prototype through focus groups, usability testing, and a technical pilot. The prototype includes three disclosure scenarios (neutral, sympathetic, and negative response) and a database of 125 virtual character utterances. Participants select a VR scenario and realistic virtual character with whom to practice. In a pilot test of the fully automated neutral response scenario, the AI system responded appropriately to 71% of participant utterances. Most pilot study participants agreed Tough Talks was easy to use (9/11) and that they would like to use the system frequently (9/11). Tough Talks demonstrates that VR can be used to practice HIV status disclosure and lessons learned from program development offer insights for the use of AI systems for other areas of health and education

HIV prevention interventions that reduce sexual risk behaviors among young Black men who have sex with men (YBMSM), the most severely affected population in the United States, are critical for reducing disparities in HIV infection. However, there are few theory-based sexual risk reduction interventions designed specifically for YBMSM. This study tested the applicability of the Integrated Behavioral Model (IBM), which theorizes that behavioral intentions mediate the relationship between psychosocial constructs and health behavior on condomless anal intercourse (CAI) among YBMSM. To test key constructs of the IBM, analyses were conducted with baseline data from the HealthMpowerment (HMP) randomized controlled trial. Logistic regression was used to examine the relationships between condom use self-efficacy, norms, attitudes, intentions, and environmental constraints, and CAI. Mediation analysis was conducted to determine if condom use intentions mediated the relationship between psychosocial constructs (i.e., condom use self-efficacy, norms, and attitudes) and CAI. Overall 55.7% reported one or more acts of CAI with a male partner in the past 3 months. Those who reported CAI in the 3 months prior to the baseline survey reported lower self-efficacy for condom use, lower condom use norms, more negative attitudes toward condom use, and lower condom use intentions at baseline than those who reported no CAI. In mediation analysis, the relationships between CAI and self-efficacy for condom use (estimated indirect effect = -0.004 (SE = 0.002)), condom use norms (-0.002 (SE = 0.001)) and attitudes toward condom use (-0.005 (SE = 0.002)) were mediated by condom use intentions. This study applied the IBM to sexual risk behavior among a sample of YBMSM. Results indicate that the relationships between condom use self-efficacy, norms, and attitudes, and CAI were mediated by condom use intentions. Future theory-informed interventions should focus on increasing self-efficacy for condom use, condom use norms, attitudes toward condom use, and condom use intentions to reduce CAI among YBMSM.
