The population-level reductions in HIV incidence attributed to pre-exposure prophylaxis (PrEP) have not been fully realized among sexual, gender, and racial/ethnic minority youth. P3 (Prepared, Protected, emPowered) is a comprehensive mobile application (app) intervention developed to support PrEP adherence through gamification, medication tracking, and social engagement. A randomized controlled trial was conducted with 246 young men who have sex with men (YMSM) and young transgender women who have sex with men (YTWMSM) currently on or planning to begin PrEP.

Article Synopsis
  • A study was conducted to assess mpox knowledge among Black young adults (ages 18-29) in Alabama, Georgia, and North Carolina to better target public health efforts.
  • Results showed a wide range of correct responses to mpox knowledge questions (26%-96%), with 26% unaware of the vaccine and 21% mistakenly believing the chickenpox vaccine offered protection against mpox.
  • Females generally had better knowledge than males, and no significant differences were found between states, indicating the need for regional educational initiatives to fill knowledge gaps and improve public health preparedness.

Background: Research has linked stigma surrounding preexposure prophylaxis (PrEP) to poor HIV prevention outcomes, including PrEP adherence. However, there remains a limited understanding of the mechanisms through which PrEP stigma affects PrEP adherence, specifically among sexual and gender minority (SGM) youth. In this study, we aimed to investigate the indirect effect of PrEP stigma on PrEP adherence through PrEP confidence and the moderating role of anticipated HIV stigma.

Article Synopsis
  • - An exploratory study in Alabama aimed to improve HIV testing rates among Black young men who have sex with men (BYMSM) by interviewing both BYMSM and outreach workers about their experiences and recommendations for better outreach efforts.
  • - Data from 56 BYMSM (average age 24) and 12 outreach workers (average age 39, mostly male and Black) revealed five key themes: promoting testing earlier, increasing visibility and outreach efforts, creating connections through shared experiences, using nonjudgmental communication, and enhancing HIV knowledge among BYMSM.
  • - The study concluded that building trust is crucial for effective HIV testing promotion among BYMSM, with recommendations to start prevention discussions at a younger age and train outreach workers in

Paediatric systemic lupus erythematosus (pSLE) management and research could be enhanced by a mobile health application (app); however, no app designed for pSLE is currently available. A development and design committee comprising of patients, parents/caregivers and other stakeholders met to inform development and design of an app specific for pSLE. This meeting report summarises the group's discussions and recommendations that could help create a useful and desirable app or mobile health tool for the pSLE community.

Disclosing one's HIV status can involve complex individual and interpersonal processes interacting with discriminatory societal norms and institutionalized biases. To support disclosure decision-making among young men who have sex with men (YMSM) living with HIV, we developed Tough Talks™, an mHealth intervention that uses artificially intelligent-facilitated role-playing disclosure scenarios and informational activities that build disclosure skills and self-efficacy. Qualitative interviews were conducted with 30 YMSM living with HIV (mean age 24 years, 50% Black) who were enrolled in a randomized controlled trial assessing Tough Talks™ to understand their experiences with HIV status disclosure.

Nearly two-thirds of new HIV infections are attributed to primary partners, necessitating a greater understanding of relationship context of HIV transmission among sexual minority men. Sexual agreements, which are the explicit decisions couples make about sexual behaviors allowed inside and outside of their relationship, have been primarily studied among adult sexual minority men. Little work has sought to understand how adolescent sexual minority men utilize and navigate sexual agreement conversations.

Background: Adolescents and young adults with HIV repeatedly demonstrate low rates of antiretroviral therapy (ART) adherence as well as low rates of viral suppression. Digital health interventions are a promising way to engage adolescents and young adults with HIV to support ART adherence. However, few digital health interventions have been developed and tested with adolescents and young adults in countries like South Africa, where the HIV burden among adolescents and young adults is greatest.

Introduction: Cultural competency has been identified as a barrier to lesbian, gay, bisexual and transgender (LGBT) populations seeking care. Mystery shopping has been widely employed in the formal health care sector as a quality improvement (QI) tool to address specific client needs. The approach has had limited use in community-based organizations due in part to lack of knowledge and resource requirement concerns.

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.

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).

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.

Background: HIV status disclosure is an important decision with barriers specific to young men who have sex with men (YMSM), who have the highest rates of new HIV infections in the United States. Behavioral and social determinants of the difficulty to disclose can include fear of rejection, stigma, loss of financial stability, and lack of communication skills. Once able to disclose, a person may have increased access to social support and improved informed risk reduction conversations and medication adherence.
