“…Later studies, however, suggested that female and male IDU engaged in injection risk behavior differently (Bennett et al, 2000;Dwyer et al, 1994;Gollub et al, 1998;Miller and Neaigus, 2001) and that risk factors for HIV infection among IDU differed between the sexes (Bruneau et al, 2001;Kral et al, 1997;Strathdee et al, 2001;van Ameijden et al, 1999). Studies reporting exclusively on HIV transmission in female IDU detected additional risk among women of color (Magura et al, 1993;Watters et al, 1994), women who engaged in prostitution (Astemborski et al, 1994;Watters et al, 1994), who were out of drug treatment (Bruneau et al, 2001), and who had a history of sexually transmitted disease Watters et al, 1994). However, far less is known about the determinants of HIV-related risk behavior among female injectors since the establishment in the U.S. of syringe exchange programs (SEPs).…”
