Prevalence of Non-medical Amphetamine Use Among Men with Diagnosed HIV Infection Who Have Sex with Men in the United States, 2015-2016.

Abstract

Amphetamine use is higher among men who have sex with men (MSM) compared with other men, and is associated with sexual behavior linked to HIV transmission. No national estimates of amphetamine use among MSM with HIV have been published. We used data from the Medical Monitoring Project, a nationally representative sample of persons with diagnosed HIV, to describe patterns in amphetamine use in the past 12months among MSM during 2015-2016 (N = 3796). Prevalence of amphetamine use in this population was 9.6% (95% CI 7.6,11.6%) in the past 12months. MSM who used amphetamines were more likely to have condomless sex with partners without HIV or of unknown serostatus (PR 1.87; 95% CI 1.62,2.16) and less likely to be durably virally suppressed (PR 0.81;95% CI 0.71, 0.91). Interventions to address amphetamine use and associated transmission risk behaviors among MSM living with HIV may decrease transmission.
