## Abstract

Project Summary
Recent HIV outbreaks among rural people who inject drugs (PWID) highlighted significant gaps in HIV prevention
science. HIV risk behaviors among PWID are influenced by several factors, including access to sterile injection
equipment and pre-exposure prophylaxis (PrEP), law enforcement practices, and utilization of medications for
opioid use disorder (MOUD) and harm reduction (e.g., accessing syringe services programs [SSPs]). None of
the existing HIV prevention literature has examined the relationships between complex patterns of interactions
and engagements among a triad of HIV risk modifiers (MOUD, harm reduction, and law enforcement), high-risk
behaviors, and HIV incidence among rural PWID during periods of peak HIV transmission. Social network
characteristics are another driver of HIV transmission as PWID networks may be characterized as having specific
norms surrounding injection practices and risk reduction strategies. Studying how combinations of factors known
to influence HIV risks interact at the individual- and network-levels among PWID in rural communities with HIV
outbreaks presents a unique opportunity to inform the design of interventions that can respond to rapidly evolving
HIV prevention needs and barriers. Evidence generated from urban studies documents that network-oriented
interventions focused on social influence processes are able to shift norms related to high-risk sexual behaviors
and injection practices and use of risk reduction strategies, leading to reductions in HIV risk behaviors and HIV
transmission. However, there is limited literature describing how to adapt network-oriented HIV prevention
interventions for rural PWID. To address these gaps, our study aims: 1. To examine longitudinal changes in the
associations between the frequency and types of engagements with a triad of HIV risk modifiers (i.e., MOUD,
harm reduction, and law enforcement), HIV risk behaviors, and HIV incidence among a cohort of rural PWID
(N=400) duri
