The goal of the current study was to examine factors that explain the effect of a cognitive-behavioral intervention, the Healthy Living Project, on HIV transmission risk reductions among HIV-infected men who have sex with men (MSM).
A total of 1,910 HIV-positive MSM were screened. Of these, 616 considered to be at risk of transmitting HIV were randomized to a 15-session, individually delivered cognitive-behavioral intervention (n=301) or a wait-list control (n=315).
"Consistent with previous intent-to-treat findings, an overall reduction in transmission risk acts was observed among MSM in the intervention and control arms," the authors reported. They found significant intervention effects at the five-, 10-, 15- and 20-month assessments (risk ratios=0.78, 0.62, 0.48 and 0.38, respectively). These intervention-related declines in HIV transmission risk acts appeared in part due to sustained serosorting practices. MSM in the intervention group reported a significantly greater proportion of HIV-positive sex partners at the five- and 10-month assessments (risk ratios=1.14 and 1.18).
