Postprison release HIV-risk behaviors in a randomized trial of methadone treatment for prisoners.

Abstract

This secondary analysis examined the impact of methadone initiated in prison on postrelease HIV risk behaviors. The parent study was a three-group randomized clinical trial in which participants received drug abuse counseling in prison and were randomly assigned to: (1) passive referral to substance abuse treatment upon release; (2) guaranteed methadone treatment admission upon release; and (3) methadone in prison and guaranteed continuation of methadone upon release. Participants were 211 adult males with preincarceration histories of opiate dependence. The AIDS Risk Assessment was administered at baseline (in prison) and at 1-, 3-, 6-, and 12-month postrelease. Data were analyzed for the entire sample (N = 211) as well as the subsamples who reported injecting drugs in the 30 days prior to incarceration (n = 131) and who reported having unprotected sex in that time frame (n = 144) using generalized linear mixed model on an intent-to-treat basis. There were no significant changes in sex- or drug-risk by Condition over Time. There were significant Time and Condition main effects for the total sample as well as the injector subsample for drug-risk behaviors. There were no significant Condition main effects for HIV sex-risk behaviors, but there were significant Time main effects. Methadone initiated in prison or immediately postrelease is associated with reduced HIV drug-risk compared to counseling in prison without methadone and passive referral to treatment at release. Participation in several drug- and sex-risk behaviors also showed significant declines during the postrelease time periods.
