“…Among IDUs, alcohol consumption and binge drinking in particular have been found to be associated with needle sharing (Arasteh and Des Jarlais, 2009;Matos et al, 2004;Poudel et al, 2010;Stein et al, 2000), multiple sex partners (Arasteh and Des Jarlais, 2009Chan et al, 2010Matos et al, 2004Poudel et al, 2010), sex under the influence of alcohol and/or drugs (Chan et al, 2010), sex with CSWs (Arasteh and Des Jarlais, 2009), sex with a paying customer (Matos et al, 2004), unprotected sex (Arasteh and Des Jarlais, 2009;Chan et al, 2010;Jenness et al, 2010;Matos et al, 2004), and injecting three or more times a day (Matos et al, 2004). For example, the odds ratio for sharing needles while intoxicated (compared to being sober) was 2.1 (CI 1.1-4.3) in a sample of 557 IDUs (89.4% male) (Matos et al, 2004). In the same sample, alcohol intoxication is associated with exchanging sex for money or drugs (Matos et al, 2004).…”
