Co-Occurring Sexual Risk and Substance Use Behaviors Among Incarcerated Adolescents.

Incarcerated adolescents report greater sexual risk than do nonincarcerated peers. High-risk sexual behavior is associated with substance use. To determine how much sexual risk is combined with substance use, 167 incarcerated adolescents reported on their sexual risk behavior in the year before incarceration that involved alcohol or marijuana. For each risk behavior, marijuana use was more likely than was alcohol use. Marijuana use was more common for higher risk behaviors than for lower risk behaviors. Periods of incarceration provide opportunities for intervening on HIV-relevant risk behaviors among adolescents. The context of substance use within high-risk sexual situations ought to be a focus of interventions for incarcerated adolescents.
