Intravenous drug users and AIDS: risk behaviors

Abstract

Risk-taking behaviors were studied in this assessment of 345 intravenous drug users from Baltimore, El Paso, and Denver. Over 50% reported injecting drugs daily and 70% shared needles with others, averaging 6.3 partners. In addition, 86% had shared a "cooker" and nearly 50% injected in a "shooting gallery." More than half of the males sampled had two or more sex partners, including 18% with five or more. Females averaged 19 sex partners in the preceding 6 months, with 22% reporting sex with five or more. Two-thirds of the total sample never used a condom, while only 6% always used this form of protection. On the other end of this risk continuum were those subjects who did not share needles or always cleaned their needles with an effective agent, had no sexual relations or always used a condom. Subjects following such practices could be considered low risk if they adopted safe behaviors in other associated areas of their lives. However, in an analysis of total risk, it was found that only 14 subjects (4%) practiced safe needle use and safe sex. Despite these findings, some encouraging results were seen. In an analysis of risk according to location, Baltimore subjects were significantly less at risk according to number of needle-sharing partners, borrowing needles, sharing a "cooker," injection in a "shooting gallery," cleaning needles, use of disinfectants, number of sexual partners, and use of condoms than either their cohorts in El Paso or Denver. Street outreach to modity risk behaviors among IVDUs began in Baltimore approximately 2 years prior to funding in El Paso and Denver. These results suggest that there may be a potential to moderate risk through intervention.
