This study was designed to analyse sexual and drug use behaviour, to determine whether increased awareness can lead to behaviour change, and to evaluate the association between HIV seropositivity and potential risk factors. A 4-month survey was carried out on 147 IVDUs attending three HIV counselling and testing centres, 98% of whom had been using heroin for an average of 7 years, 85% in association with other drugs. Two-thirds of injectors reported having used "safer" injecting practices in the previous year. Most of the IVDUs were heterosexual, and had had an average of three sexual partners in the previous year. More than half of them had had high risk partners. Condoms were used by only 25% of IVDUs, and were more likely to be used with seropositive partners (38% versus 12.7%, p = 0.02). Patients considering themselves to be well informed about HIV transmission shared syringes significantly less often, but had the same sexual behaviour patterns as other subjects. The HIV prevalence rate (8.2%) in our sample was not statistically related to any risk factor apart from drug use duration, the latter possibly reflecting a cumulative exposure to HIV risks. Since sexual risk appears to be a potential long-term hazard for IVDUs, it is important that more attention be paid to providing counselling to specifically address this issue.
本研究旨在分析性行为和吸毒行为，确定意识的提高是否能导致行为改变，并评估艾滋病毒血清阳性与潜在危险因素之间的关联。对前往三个艾滋病毒咨询和检测中心的147名注射吸毒者进行了为期4个月的调查，其中98%的人平均吸食海洛因7年，85%的人还使用其他毒品。三分之二的注射者报告在前一年采用了“更安全”的注射方式。大多数注射吸毒者为异性恋，前一年平均有三个性伴侣。其中一半以上有高危性伴侣。只有25%的注射吸毒者使用避孕套，与血清阳性伴侣使用避孕套的可能性更高（38%对12.7%，p = 0.02）。自认为对艾滋病毒传播有充分了解的患者共用注射器的频率明显较低，但性行为模式与其他受试者相同。我们样本中的艾滋病毒感染率（8.2%）与除吸毒持续时间外的任何危险因素均无统计学关联，吸毒持续时间可能反映了对艾滋病毒风险的累积暴露。由于性风险似乎是注射吸毒者潜在的长期危害，因此重要的是要更加重视提供咨询以专门解决这一问题。
