这项横断面调查采访了2003年8月至2004年6月在中国成都市三个戒毒中心收治的海洛因注射者。进行逻辑回归和生存分析，以确定分别与共用针头/注射器以及从开始海洛因到采用注射的时间相关的因素。在 266 名受试者中，206 名（77.44%）为男性，103 名（38.72%）从未共用过注射材料，113 名（42.48%）为非成都市居民，9 名（3.38%）为少数民族。海洛因注射史较短（P < 0.05）和少数民族（P < 0.05）的人更可能共用注射物质。只有年龄、种族和海洛因使用持续时间与首次注射时间相关。对于使用海洛因长达 1 年的人来说，注射时间的中位时间为 6 个月，而对于使用海洛因 2-5 年的人来说，注射时间的中位时间为 21 个月。研究表明，海洛因使用者很早就开始注射，并且共用注射材料的比例很高，这是艾滋病毒传播的主要风险。少数民族被认为是风险最高的群体，需要进一步关注。 (c) 2005 Elsevier Ltd. 保留所有权利。
This cross-sectional survey interviewed heroin injectors admitted in three detoxification centres from August 2003 to June 2004 in Chengdu City, China. Logistic regression and survival analysis were performed to identify factors associated with sharing of needles/syringes and time from initiation of heroin to adoption of injection, respectively. Out of 266 subjects studied, 206 (77.44%) were males, 103 (38.72%) never shared injecting materials, 113 (42.48%) were non-Chengdu residents and 9 (3.38%) belonged to ethnic minorities. Those with short history of heroin injection (P < 0.05) and those belonged to ethnic minorities (P < 0.05) were more likely to share injecting materials. Only age,, ethnicity and duration of heroin use were associated with time to first injection. Median time to injection was 6 months for those who used heroin for the duration up to I year and 21 months for those who used heroin for 2-5 years. The study suggests that there is early initiation of injection and sharing of injecting materials is high among heroin users, a major risk for HIV transmission. Ethnic minorities have been identified to be the most risky group, which needs further attention. (c) 2005 Elsevier Ltd. All rights reserved.
