“…Strong associations between substance use and sexual risk behaviours have been reported previously and include smoking, drinking, and drug use being associated with sexual risk behaviours in general (Duncan, Strycker, & Duncan, 1999; Jackson, Sweeting, & Haw, 2012; Tu, Lou, Gao, Li, & Zabin, 2012), early sexual debut (Lowry et al, 1994), and number of sexual partners (Lowry et al, 1994; Shrier, Emans, Woods, & DuRant, 1997). Binge drinking has been associated with a higher number of partners (Guo et al, 2002), while more generally alcohol consumption has been associated with sexual debut, multiple sexual partners, and unprotected sex, all of which lead to an increased risk of HIV infection (Ayisi et al, 2000; Bassett et al, 1996; Clift et al, 2003; Lewis et al, 2005; Mnyika, Klepp, Kvale, & Ole-King’Ori, 1997; Myer, Mathews, & Little, 2002; Somsé, Chapko, & Hawkins, 1993; Zachariah et al, 2003). The increased risk of HIV infection may be attributable to the social consequences of substance use, which facilitates unprotected sex.…”
