Background. HIV rates among young adults remain high, and those impacted by the justice system are at particular risk. Understanding the factors associated with HIV testing, as well as determining changes in risk behavior after an HIV test, may inform interventions to reduce HIV prevalence among this population. Objective. To determine the individual, contextual, and demographic factors associated with HIV testing among legal-system-impacted young adults, and to explore whether a first HIV test is associated with future risky behavior when compared to never-tested individuals.
Design. This retrospective longitudinal study included those adjudicated by the criminal legal system between ages 14-17. Data were collected between 2000-2010; analyses were completed in 2021-2022.
Setting. Interviews occurred in participants’ homes and community and correctional settings.
Participants. Participants were enrolled in Pathways to Desistance, a study that followed adolescents for seven years after an arrest for a serious offense. In total, 1,354 eligible and interested youth in Pennsylvania and Arizona were enrolled in Pathways, and a diverse subset of 981 male participants were included in this study.
Main Outcomes and Measures. Receipt of HIV testing served as the primary outcome; secondary outcomes included frequency of unprotected sex, number of unprotected sexual partners, and alcohol, marijuana, cigarette, and illicit drug use. Hypotheses were generated after data collection was completed.
Results. Significant predictors of HIV testing included the total number of sexual partners (OR=1.05, p=0.04), the absence of a biological father (OR=0.50, p=0.003), and living in Arizona vs. Pennsylvania (OR=0.272, p<0.001). Compared to those never tested for HIV, those newly tested significantly differed in the number of unprotected sexual partners (b=0.28, p<0.001), frequency of unprotected sex (b=0.36, p<0.001), and frequency of alcohol (b=0.28, p<0.001) and cigarette use (b=0.27, p<0.001) one year later.
Conclusions and Relevance. This study is one of the first to assess predictors of HIV testing among legal-system-impacted young adults living in community and carceral settings, and to assess changes in risk behavior before and after a first HIV test. Future studies should investigate changes in risk behavior among those newly tested to inform HIV testing and care improvement interventions for this population.
