The HIV risks associated with the sexual behaviour of drug injectors have sometimes been overshadowed by the more obvious risks of injection behaviour. In this study, 408 heroin users were interviewed in the community; 50% were not currently in treatment and 42% had never had any treatment contact. In addition to data on drug use, information was collected on sexual risk behaviour by means of a linked anonymous questionnaire (96% returned). Eighty-nine per cent of the sample had had at least one sexual partner in the previous year and 58% had a regular sexual partner at the time of interview. Drug users who had a sexual partner who was injecting drugs were more severely dependent upon heroin. Twenty-three per cent of the men and 20% of the women reported having had anal intercourse in the previous year. Seventeen per cent of the women and 6% of the men had engaged in some form of prostitution. Severity of heroin dependence was positively related to the occurrence and to the frequency of sex-for-money transactions and to the less well recognized phenomenon of sex-for-drugs; this association with severity of dependence applied to the women and to the men who have sex with men. The overall level of condom use was low in this sample, though condom use was more frequent among those involved in sex-for-money or sex-for-drugs transactions. Low levels of condom use were reported even for such high risk activities as anal sex.(ABSTRACT TRUNCATED AT 250 WORDS)
与药物注射者性行为相关的艾滋病病毒感染风险，有时会被更为明显的注射行为风险所掩盖。在本研究中，对社区中的408名海洛因使用者进行了访谈；50%的人目前未接受治疗，42%的人从未有过任何治疗接触。除了药物使用数据外，还通过一份关联匿名问卷（回收率96%）收集了性风险行为信息。样本中89%的人在前一年至少有过一个性伴侣，58%的人在访谈时拥有固定性伴侣。有注射毒品性伴侣的吸毒者对海洛因的依赖程度更深。23%的男性和20%的女性报告在前一年有过肛交。17%的女性和6%的男性从事过某种形式的卖淫活动。海洛因依赖的严重程度与以性换钱交易的发生频率以及鲜为人知的以性换毒品现象呈正相关；这种与依赖严重程度的关联适用于女性和男同性恋者。该样本中避孕套的总体使用率较低，不过在涉及以性换钱或性换毒品交易的人群中，避孕套的使用更为频繁。即使是对于肛交这种高风险行为，避孕套的使用率也很低。（摘要截选至250字）
