Peer-led adjunctive interventions for increasing the reach of HIV prevention and care interventions to Latino/x/e men who have sex with men: A scoping review

PURPOSE OF REVIEW: Latino/x/e men who have sex with men (LMSM) in the United States are disproportionately affected by HIV. Peer-led adjunctive interventions show promise for enhancing engagement in HIV prevention and care among LMSM, but their effectiveness and implementation remain underexplored. This scoping review aimed to map existing evidence on peer-led interventions, identify gaps, and inform future research for enhancing HIV prevention and care among LMSM. RECENT FINDINGS: We followed PRISMA-ScR guidelines, covering literature from 2011 to 2022, using Covidence for systematic screening and data extraction. Articles were categorized by intervention aspects like delivery methods, outcomes, translational phases, theory-informed approaches, and cultural adaptation levels. The search yielded 613 records, with 22 meeting eligibility criteria, including 17 unique interventions. Interventions were delivered individually (57%), in groups (30%), to couples (4%), and via public campaigns (4%). Outcomes included HIV testing uptake (74%), treatment linkage (39%), PrEP uptake (22%), and PEP uptake (4%). Translational phases included formative (22%), pilot (26%), efficacy (22%), and effectiveness (22%). Cultural adaptations were surface (22%) and deep (13%). Findings indicate diverse peer-led interventions for LMSM, though many are in early stages of development. Further research is needed to move these interventions along the translational pathway to enhance their public health impact.
