Prevalence of HIV risk-related drug use and sexual activity among men who have sex with men attending a specialist UK club drug clinic

The purpose of this paper is to examine patterns of drug use among a cohort of drug treatment-seeking drug-using gay men and other men who have sex with men (MSM), and whether these activities differ between, or predict, HIV status.

Cross-sectional study was conducted in a specialist club drug clinic in London covering 407 consecutive attendees who identified as MSM. Substance use, including injecting drug use (IDU), associated sexual activity and self-reported HIV status were measured by clinical interview and National Drug Treatment Monitoring System data tool.

Over a 45-month period, 407 MSM attended the clinic. In total, 62.1 per cent were HIV positive, 48.9 per cent had injected drugs, 14.9 per cent reported needle sharing and 73.3 per cent used drugs to facilitate sex. The most commonly reported problem drugs were GHB/GBL (54.3 per cent) methamphetamine (47.7 per cent) and mephedrone (37.8 per cent). HIV status was associated with methamphetamine, mephedrone, IDU, sharing equipment, using drugs to facilitate sex, older age and older age of drug initiation, as well as Hepatitis C virology (HCV) status. Use of methamphetamine, HCV infection, older age and IDU predicted HIV positive status in a logistic regression model.

The findings describe a constellation of risk factors including high levels of IDU, sharing of equipment and high-risk sexual activity in a population with high rates of HIV positive serology. They also provide further evidence for a link between HIV infection and use of methamphetamine.

The authors suggest a need for greater awareness of HIV-related risk activities and promotion of HIV prevention strategies for MSM by both sexual health and drug treatment services.

This paper is amongst the very first studies of its nature.
