Impact of a Brief Intervention for Substance Use on Acquisition of Sexually Transmitted Diseases Including HIV: Findings From an Urban Sexually Transmitted Disease Clinic Population.

Background: Unhealthy substance use is associated with increased rates of sexually transmitted diseases (STDs), including HIV. The screening, brief intervention, and referral to treatment strategy is effective at reducing substance use over time. We investigated whether STD clinic patients who received a brief intervention (BI) had lower rates of STD/HIV acquisition over time than those who did not.
