Intravenous drug users (IDUs) are at high risk of contracting HIV, but there is a geographic bias in such research efforts in China. The aim was to study the pattern of needle sharing and sex-related risk behaviours among drug users in southern China. About 260 drug users in a detoxification centre completed an anonymous questionnaire (response rate=87.3%). The results show that needle sharing among IDUs was prevalent (60.6% and 45.3% for male and female IDUs, respectively); the sharers were often friends, spouses, and acquaintances. Few IDUs sterilized the used needles properly. Commercial sex behaviours (males: 44%; females: 60%) as well as multiple partnership (males: 60%; females: 53%) were also prevalent among all male and female drug users studied. Inconsistent condom use with commercial sex partners, spouses, and regular sex partners was also very common. Yet, few of all drug users studied perceived the susceptibility of contracting HIV (11%) or sexually transmitted diseases (24%) in the future. A better HIV-related knowledge level was associated with lower levels of risk behaviours. It is concluded that harm reduction programmes are urgently warranted in China.
静脉注射吸毒者感染艾滋病毒的风险很高，但中国在这方面的研究工作存在地域偏差。目的是研究中国南方吸毒者共用针头及与性相关的危险行为模式。一家戒毒中心的约260名吸毒者完成了一份匿名问卷（回复率=87.3%）。结果显示，静脉注射吸毒者中共用针头的情况很普遍（男性和女性吸毒者分别为60.6%和45.3%）；共用者通常是朋友、配偶和熟人。很少有吸毒者对用过的针头进行适当消毒。在所研究的所有男性和女性吸毒者中，商业性行为（男性：44%；女性：60%）以及多性伴行为（男性：60%；女性：53%）也很普遍。在与商业性伴侣、配偶和固定性伴侣发生性行为时不坚持使用避孕套的情况也很常见。然而，在所研究的所有吸毒者中，很少有人认为自己未来感染艾滋病毒（11%）或性传播疾病（24%）的易感性。较好的艾滋病毒相关知识水平与较低的危险行为水平相关。结论是，中国迫切需要开展减少伤害项目。
