This study determined whether bisexual male injecting drug users (IDUs) as compared with heterosexual IDUs were more likely to engage in HIV-associated risk behaviours. Respondent-driven sampling was employed to recruit a sample of 382 male IDUs residing in the southeastern USA. Data were collected in face-to-face interviews. Weighted analyses showed that bisexual IDUs in the past 12 months were 4.6 times as likely to share needles and 3.5 times as likely to share a cooker; having multiple female sexual partners and trading money or drugs for sex with women were marginally significant. Bisexual IDUs were 10 times as likely to self-report HIV. Male IDUs, who engage in bisexual behaviour, are also engaging in HIV-associated drug and to some degree sexual-risk behaviours with women more so than heterosexual IDUs. Their higher prevalence of HIV infection coupled with their risk behaviours place themselves and other IDUs at heightened risk of both acquiring and transmitting HIV.
本研究确定了与异性恋注射吸毒者相比，双性恋男性注射吸毒者是否更有可能从事与艾滋病毒相关的危险行为。采用应答者驱动抽样方法，招募了居住在美国东南部的382名男性注射吸毒者作为样本。通过面对面访谈收集数据。加权分析表明，在过去12个月中，双性恋注射吸毒者共用针头的可能性是异性恋注射吸毒者的4.6倍，共用烹饪器具的可能性是异性恋注射吸毒者的3.5倍；拥有多个女性性伴侣以及与女性进行金钱或毒品交易以换取性行为的情况在统计学上具有边缘显著性。双性恋注射吸毒者自我报告感染艾滋病毒的可能性是异性恋注射吸毒者的10倍。从事双性行为的男性注射吸毒者，与异性恋注射吸毒者相比，在与女性进行与艾滋病毒相关的毒品及某种程度的性危险行为方面更为频繁。他们较高的艾滋病毒感染率及其危险行为使他们自己以及其他注射吸毒者感染和传播艾滋病毒的风险增加。
