A Latent Class Analysis of HIV Risk Factors Among Men and Women with Opioid Use Disorder in Pre-trial Detention.

Adults entering pre-trial detention who inject drugs are at high risk for acquiring HIV/AIDS. In the current study, we examined pre-incarceration HIV risk behaviors among 114 people with opioid use disorder who inject drugs. Participants were recruited from the Baltimore City Detention Center as part of a randomized controlled trial of pre-release methadone treatment. Using latent class analysis, we found three separate latent classes, which we identified as the sex exchange class (14.2%), drug equipment sharing class (36.8%) and lower risk class (49.0%). Women in the sex exchange class (n = 16) reported having multiple male partners and selling sex for money or drugs; however, this group also reported more consistent condom use and less frequent injection drug and equipment sharing than participants in the drug equipment sharing class. Our findings highlight distinct profiles of jail detainees with OUD based on their risks for HIV, and could inform more targeted interventions for each group.Clinical Trials Registration: Clinicaltrials.gov NCT02334215.
