RELEVANCE: Stimulant use, especially among men who have sex with men (MSM) in Los Angeles County (LAC) is common. Stimulant drug use, particularly methamphetamine use, is a significant factor in the progression of HIV and STI among MSM in LAC. Non-white MSM are at greatest risk of HIV infection in the United States. Analyses of drug use are needed among diverse samples of MSM in order to understand the impact of drug use on the HIV epidemic over time and to address the effect of long-term drug use patterns on uptake and adherence to treatment and prevention of the disease.
DESCRIPTION: The goal of this project is to assemble a cohort of minority men who have sex with men (MMSM) who actively use substances and engage transmission risks. This will facilitate studies on interactions between substance use and HIV progression and/or transmission. This important cohort of MMSM will characterize: (i) effects substance use on risk behaviors, and network dynamics in exposed and infected MMSM on acquisition of HIV and other sexually transmitted infections (STIs: gonorrhea, Chlamydia, syphilis, Hepatitis C (HCV)); and (ii) the extent to which substance use in MMSM facilitates behaviors that transmit HIV compared to non-drug using MMSM.
