This study examined differences in sexual risk behaviors by gender and over time among 1281 patients (777 males and 504 females) from 12 community-based substance use disorder treatment programs throughout the United States participating in CTN-0032, a randomized controlled trial conducted within the NIDA Clinical Trials Network. Zero-inflated negative binomial and negative binomial models were used in the statistical analysis. Results indicated significant reductions in most types of sexual risk behaviors among substance users regardless of the intervention arms. There were also significant gender differences in sexual risk behaviors. Men (compared with women) reported more condomless sex acts with their non-primary partners (IRR=1.80, 95% CI 1.21–2.69) and condomless anal sex acts (IRR=1.74, 95% CI 1.11–2.72), but fewer condomless sex partners (IRR=0.87, 95% CI 0.77–0.99), condomless vaginal sex acts (IRR=0.83, 95%CI 0.69–1.00), and condomless sex acts within 2 hours of using drugs or alcohol (IRR=0.70, 95%CI 0.53–0.90).
Conclusions: Significant reductions in most types of sexual risk behaviors were observed among participants in substance use disorder treatment, in the forms of increased abstinence and decreased number of condomless sex acts. These findings provide evidence that substance use disorder treatment may lead to HIV risk reduction. For the most part, gender differences showed women to have higher levels of risk than men, having more unprotected sex with primary partners and partners of unknown HIV status than men. Women also reported 30% more condomless sex acts within two hours of using drugs or alcohol compared to men in the study group. Gender-specific intervention approaches are called for in substance use disorder treatment. (Article (Peer-Reviewed), PDF, English, 2016)
