Factors Associated with the Discordance between Perception of Being HIV Infected and HIV Sexual Risk Taking among Social Media-Using Black, Hispanic, and White Young Men Who Have Sex with Men

Perceived risk for HIV acquisition and sexual HIV exposure among sexual and gender minorities: a systematic review

We conducted a systematic review to explore the relationship between perceived risk for HIV acquisition and sexual HIV exposure among sexual and gender minorities. We included 39 studies divided into (i) correlations or associations, (ii) models using sexual HIV exposure as the outcome, and (iii) models using perceived risk for HIV acquisition as the outcome. The sample size range was from 55 to 16,667 participants, primarily cisgender men who have sex with men (73.3%) and White (51.3%). Sexual HIV exposure and perceived risk for HIV acquisition assessments and recall time frames across studies differed markedly. Most of studies (84.6%) found significant correlations, comparisons, or associations between different levels of perceived risk for HIV acquisition and high sexual HIV exposure. In addition, 51.3% of studies reported other variables associated with high sexual HIV exposure (i.e., misuse of substances or alcohol) or with high perceived risk for HIV acquisition (i.e., younger age). In conclusion, the association between perceived risk for HIV acquisition and sexual HIV exposure has shown to be consistent. However, the assessment for perceived risk for HIV acquisition should include more components of perception (i.e., an affective component), or for sexual HIV exposure should consider the different estimated sexual per-acts probability of acquiring HIV.

Uptake and Acceptability of MyChoices: Results of a Pilot RCT of a Mobile App Designed to Increase HIV Testing and PrEP Uptake Among Young American MSM

Young men who have sex with men (YMSM) remain at disproportionate risk for HIV acquisition in the United States (US), yet use of evidence-based prevention strategies, including routine HIV testing and pre-exposure prophylaxis (PrEP), remain low. Smartphones and mobile app usage are nearly ubiquitous in this population. Given the potential for scalability, a mobile app to increase HIV testing and PrEP use among YMSM has the potential to make an extraordinary public health impact if efficacious. Based on extensive formative, community-engaged research, we developed a theory-driven mobile app-MyChoices-to increase HIV testing and PrEP uptake among YMSM. In a pilot randomized controlled trial (RCT), participants (n = 60) were randomized 2:1 to receive MyChoices or standard of care (SOC). Data from 3 to 6-month post-baseline assessments demonstrate that the app was highly acceptable (System Usability Score; mean = 75.8, SD = 10.7) and feasible (94% used the MyChoices app at least once; mean = 15.3 sessions, SD = 9.8). While not powered to assess efficacy, those in the MyChoices arm had 22% higher prevalence of HIV testing over follow-up compared to those in the SOC arm (NS). There was no difference in PrEP uptake. A fully-powered efficacy trial is warranted; if efficacy is demonstrated, the MyChoices app could be easily scaled to reach YMSM across the US.

Constructions of HIV Risk Among a Diverse Sample of HIV-Negative Young Men Who Have Sex With Men Who Are Repeat Testers

INTRODUCTION

To end the HIV epidemic, HIV prevention and pre-exposure prophylaxis (PrEP) promotion efforts must reach young men who have sex with men (YMSM) at greatest risk for HIV. This study qualitatively explored whether common metrics used by clinicians, scientists, and public health officials to objectively assess HIV risk align with how YMSM conceptualize their risk for HIV and the factors that shape YMSM's risk perceptions.

METHODS

Interviews with a racially/ethnically diverse sample of HIV-negative YMSM (ages 19-24 years, 60% Latinx; n = 20) examined conceptualizations of HIV risk within the context of repeat HIV testing. Iterative, applied thematic analysis examined how participants conceptualized and constructed their HIV risk, and compared participants' descriptions of their risk with a validated quantitative assessment of HIV risk that reliably predicts HIV seroconversion in this group.

RESULTS

Objective quantitative assessments of HIV risk poorly aligned with participants' perceived HIV risk. Participants described their current risk in relative terms (relative to past risk and relative to friends'/peers' risk) and described age/developmental stage and changes in knowledge about HIV prevention as key factors in risk changes over time. Other factors included substance use and trust/mistrust in sexual partners and scientific advances in HIV prevention (eg, U = U and PrEP). Factors that influenced participants' perceived HIV risk were similar regardless of objective risk assessment.

CONCLUSIONS

Quantitative assessments of risk may poorly align with risk perception among YMSM. Although objective metrics can effectively target YMSM at greatest risk for HIV transmission, interventions to improve prevention behaviors and PrEP uptake may be more effective when tailored to bridge the disconnection between objective HIV risk assessments and YMSM's constructions of risk.
