摘　　要：目的了解不同注射吸毒时间的吸毒者艾滋病知识的影响因素。方法于2003-2005年对四川省注射吸毒者进行3次横断面调查,调查内容包括人口学、注射吸毒行为、性行为及艾滋病相关知识等。应用K-means聚类法对调查对象的艾滋病知识水平进行聚类,然后对所有被调查者和不同注射吸毒时间(<1年,1～3年和>3年)的吸毒者进行累积Logistic回归分析。结果4310例被调查者中,注射吸毒<1年者占14.1%,1～3年占40.3%,>3年占45.6%。调查对象按艾滋病知识掌握的程度,被聚类为3类,I类2547人(好),II类共1447人(中),III类共313人(差)。注射吸毒<1年者艾滋病知识的独立影响因素包括少数民族、注射频率低、未戒过毒、未曾得到发放的安全套、未得到过性病艾滋病预防知识讲解及未曾得到宣传材料。注射吸毒1～3年者艾滋病知识的独立影响因素包括文化程度低、未曾得到宣传材料、未参与针具交换、未曾接受性病检查或治疗、2004年及2005年招募者、招募于达州、凉山、自贡。注射吸毒大于3年者艾滋病知识的独立影响因素包括文化程度低、少数民族、未戒过毒、未参与针具交换、2004年及2005年招募者。结论调查显示半数以上注射吸毒者吸毒时间小于3年。文化程度低、少数民族、未曾得到HIV干预服务者艾滋病知识水平较低。,提示针对不同吸毒时间吸毒者的干预宣传侧重有所不同。Objective To assess the risk factors for HIV-related knowledge among injection drug users with different drug injecting history （IDUs） in Sichuan Province, China. Methods Three consecutive cross-sectional surveys were conducted in Sichuan＇s six prefectures from 2003 to 2005. Questionnaire-based interview provided information including sociodemographics, drug use and sexual behaviors, and HIV-related services. Clustering analysis and cumulative logistic regression were used for data analysis. Results Of 4 310 eligible participants, 14. 1% of the participants were less than one-year IDUs, 40. 3% one-to-three year IDUs, 45.6% more than three-year IDUs. All participants were clustered into three groups： 2 547 IDUs in group I with higher level of HIV-related knowledge, 1 447 in group Ⅱ with mid-level of HIV-related knowledge, and 313 IDUs in group Ⅲ with lower level of HIV-related knowledge. Less than one-year IDUs with being minority, less frequent injecting, never received detoxification, never received free condom, never attended lecture of AIDS/ STD prevention, and never received HIV-related education materials were more likely to have lower level of HIV-related knowledge. One-to-three year IDUs with less education, never received HIV-related education materials, never attended syringe exchange programs, never take examination or treatment for STD, being recruited in 2004 and 2005, and being recruited form Dazhou, Liangshan , and Zigong were more likely to have lower level of HIV-related knowledge. More than three-year IDUs with less education, being minority, never received detoxification, never attended syringe exchange programs, and being recruited in 2004 and 2005 were more likely to have lower level of HIV-related knowledge. Conehlsion More than half of the participants injected drugs for 〈 3 years. These who were new IDU, being minority, less education, and never participated in any HIV intervention programs scored lower on HIV-related knowledge. It suggests that publicity and interventions sho
