Abstract
BACKGROUND
Alcohol is associated with a multitude of severe health consequences. While risk behaviors related to illicit drug use are commonly studied among people who inject drugs (PWID), the role of alcohol use has received substantially less attention in this population. We explored whether drug and sexual risk behaviors as well as experiences of violence were associated with hazardous alcohol use in a cohort of PWID.

METHODS
Analyses were conducted using observational data from a prospective cohort of community-recruited HIV-negative PWID in Vancouver, Canada. We used the U.S. National Institute on Alcohol Abuse and Alcoholism definition of hazardous alcohol use (i.e., >14 drinks/wk or >4 drinks on 1 occasion for men, and >7 drinks/wk or >3 drinks on 1 occasion for women). We used multivariable generalized estimating equations (GEE) to identify the factors associated with hazardous alcohol use.

RESULTS
Between 2006 and 2012, 1,114 HIV-negative individuals were recruited, and 186 (16.7%) reported hazardous alcohol use in the previous 6 months at baseline. In multivariable GEE analyses, having multiple sex partners (adjusted odds ratio [AOR] = 1.25), history of sexually transmitted infection (AOR = 1.50), experiencing violence (AOR = 1.36), and incarceration (AOR = 1.29) were each independently associated with hazardous alcohol use. Caucasian ethnicity (AOR = 0.56), ≥ daily heroin injection (AOR = 0.81), and engagement in addiction treatment (AOR = 0.84) were negatively associated with hazardous alcohol use (all p < 0.05). CONCLUSIONS
A considerable proportion of PWID reported hazardous alcohol use, which was independently associated with reporting sexual, but not drug-related, HIV risk behaviors and experiencing recent violence. Findings suggest a need to integrate regular screening and evidence-based alcohol interventions into treatment efforts for PWID.
