This study investigated the drug use patterns and HIV risk-taking behaviour of 200 injecting drug users (IDU) not currently in treatment in Sydney, Australia. Although there was low HIV seroprevalence, unsafe injecting and sexual practices were common. Variables that were predictive of injecting risk-taking were higher level of heroin use, sexual relationship with an IDU and greater polydrug use. Two variables were predictive of sexual risk-taking: higher level of hallucinogen use and sexual relationship with an IDU. Female subjects were significantly more likely to have an IDU sexual partner. A higher level of cannabis use was associated with greater polydrug use and a higher level of amphetamine use was associated with greater use of opiates other than heroin. The findings are discussed in terms of the need for interventions aimed towards reducing sexual risk-taking among users of hallucinogens and towards reducing injecting and sexual risk-taking among IDU and their sexual partners. The potential difficulty in producing behaviour change among polydrug users is highlighted.
本研究调查了澳大利亚悉尼200名目前未接受治疗的注射吸毒者（IDU）的用药模式和感染艾滋病毒的风险行为。尽管艾滋病毒血清流行率较低，但不安全的注射和性行为很常见。预测注射风险行为的变量包括海洛因使用量较高、与注射吸毒者发生性关系以及多种药物混合使用程度较高。有两个变量可预测性行为风险：致幻剂使用量较高以及与注射吸毒者发生性关系。女性受试者与注射吸毒者发生性伴侣关系的可能性显著更高。大麻使用量较高与多种药物混合使用程度较高相关，苯丙胺使用量较高与除海洛因外的其他阿片类药物使用量较高相关。根据针对减少致幻剂使用者的性行为风险以及减少注射吸毒者及其性伴侣的注射和性行为风险的干预措施需求，对研究结果进行了讨论。强调了在促使多种药物使用者改变行为方面可能存在的困难。
