Among HIV-positive injection drug users (IDUs), we examined the correlates of lending needles/syringes with HIV-negative and unknown status injection partners. HIV-positive IDUs (N=738) from 4 cities in the United States who reported injection drug use with other IDUs in the past 3 months participated in an audio computer-assisted self-administered interview. Eighteen percent of study participants self-reported having lent their needles to HIV-negative or unknown status injection partners. Multivariate analyses showed that 6 variables were significantly associated with this high-risk injecting practice. Older IDUs, high school graduates, and those reporting more supportive peer norms for safer drug use were less likely to lend needles/syringes. Admission to a hospital for drug treatment in the past 6 months, having injected with >1 person in the past 3 months, and having more psychiatric symptoms were all associated with more risk. These findings underscore the need for a continued prevention focus on HIV-positive IDUs that recognizes the combination of drug use, mental health factors, and social factors that might affect this high-risk injecting practice, which could be associated with HIV and hepatitis C transmission.
在艾滋病毒呈阳性的注射吸毒者中，我们研究了将针头/注射器借给艾滋病毒呈阴性及感染状况不明的注射伙伴的相关因素。来自美国4个城市的738名艾滋病毒呈阳性的注射吸毒者参与了一项音频计算机辅助自填式访谈，这些人报告在过去3个月内与其他注射吸毒者一起注射毒品。18%的研究参与者自述曾将自己的针头借给艾滋病毒呈阴性或感染状况不明的注射伙伴。多变量分析显示，有6个变量与这种高风险注射行为显著相关。年龄较大的注射吸毒者、高中毕业生以及那些报告称同伴对更安全吸毒的规范支持度更高的人，出借针头/注射器的可能性较小。过去6个月内因药物治疗而住院、过去3个月内与不止一人一起注射以及有更多精神症状，都与更高的风险相关。这些发现强调，有必要继续针对艾滋病毒呈阳性的注射吸毒者开展预防工作，认识到可能影响这种高风险注射行为的药物使用、心理健康因素和社会因素的综合作用，而这种行为可能与艾滋病毒和丙型肝炎传播有关。
