A multi-site sample of currently-injecting drug users (IDUs) comprising 344 men and 136 women was recruited in Edinburgh. Sixty-seven per cent of the sample said they had at some time used injecting equipment already used by another person and 25% admitted doing so in the 6 months before interview. Whereas women who injected with used equipment obtained it predominantly from a sexual partner, for men the source was more often a close friend or someone whose HIV status they were unlikely to know. In the 6 months before interview, 40% of men, compared with 20% of women, had more than one heterosexual partner. This difference was associated with a higher proportion of men with steady partners also having casual partners. Women IDUs were more likely to have regular partners who injected (57% vs 26%). Though sharing of injecting equipment has already diminished in Edinburgh, further measures are needed to eliminate it. For injectors here, the risk of infection from unprotected heterosexual intercourse may now be greater than that from sharing injecting equipment, particularly for women. Other methods of encouraging changes in sexual behaviour need to be investigated and successful ones promoted.
在爱丁堡招募了一个多地点的当前注射吸毒者样本，其中包括344名男性和136名女性。67%的样本表示他们曾在某些时候使用过他人用过的注射器具，25%的人承认在接受访谈前的6个月内这样做过。使用过的器具，女性主要从性伴侣那里获得，而男性则更多地来自密友或他们不太可能知道其艾滋病毒感染状况的人。在接受访谈前的6个月里，40%的男性有不止一个异性伴侣，而女性这一比例为20%。这种差异与有固定伴侣的男性中也有临时伴侣的比例较高有关。女性注射吸毒者更有可能有注射毒品的固定伴侣（57%对26%）。虽然在爱丁堡，共用注射器具的情况已经有所减少，但仍需采取进一步措施来消除这种现象。对于这里的注射吸毒者来说，无保护的异性性行为感染的风险现在可能大于共用注射器具感染的风险，尤其是对女性而言。需要研究鼓励性行为改变的其他方法，并推广成功的方法。
