Injecting drug users (IDUs) play a disproportionate role in the spread of HIV given their injecting and sexual contacts, and thereby act as conduits between these risk groups. We investigated differences in risk behaviour and HIV seroprevalence in a Sydney sample of 1,245 IDUs. Significant differences were observed across sexual orientation in HIV serostatus for males, with homosexual men having the highest HIV seroprevalence rate (35%), bisexual men intermediate (12%) and heterosexual men lowest (3%). Sexual HIV risk behaviours were lowest for homosexual men, intermediate for bisexual men, and highest for heterosexual men in the case of condom use: however, for numbers of partners, seroprevalence, and anal sex the trends were reversed. There were no differences across sexual orientation for either sex for injecting drug risk behaviours. Both male and female respondents reported having more than 50% of sexual contacts while under the influence of drugs. This study suggests that risk reduction in the sexual domain has not generalized to the injecting risk domain regardless of sexual orientation, and demonstrates that sexual risk behaviours in IDUs are lowest in homosexual, intermediate in bisexual, and highest in heterosexual IDU men.
注射吸毒者因其注射行为和性接触，在艾滋病毒传播中扮演着不成比例的角色，从而成为这些风险群体之间的传播渠道。我们调查了悉尼1245名注射吸毒者样本中的风险行为差异和艾滋病毒血清阳性率。在男性的艾滋病毒血清状态方面，观察到不同性取向之间存在显著差异，男同性恋者的艾滋病毒血清阳性率最高（35%），双性恋男性居中（12%），异性恋男性最低（3%）。在使用避孕套方面，男同性恋者的性艾滋病毒风险行为最低，双性恋男性居中，异性恋男性最高；然而，在性伴侣数量、血清阳性率和肛交方面，趋势则相反。在注射吸毒风险行为方面，无论男女，不同性取向之间均无差异。男性和女性受访者均报告称，超过50%的性接触是在吸毒影响下发生的。这项研究表明，无论性取向如何，性领域的风险降低并未推广到注射风险领域，并且表明注射吸毒者的性风险行为在男同性恋者中最低，在双性恋者中居中，在异性恋注射吸毒者中最高。
