摘　　要：目的了解新注射吸毒者和长期注射吸毒者共用针具的影响因素。方法对四川省注射吸毒者进行社区横断面调查。结果3852名被调查者中，注射吸毒史〈1年、1～3年和〉3年者最近6个月共用针具比例依次为19．9％、29．1％和36．3％。注射吸毒〈1年的被调查者共用针具的独立影响因素包括女性、少数民族、注射吸毒频率高、共用注射器／针头以外其他吸毒用具、有非固定性伴、固定性伴注射吸毒、未自愿做过艾滋病检测、招募年、招募地区；注射吸毒1～3年的被调查者共用针具的独立影响因素包括文化程度低、注射频率高、共用注射器，针头以外其他吸毒用具、有非固定性伴、固定性伴注射吸毒、未使用安全套、未参与技能培训、招募年、招募地区；注射吸毒〉3年的被调查者共用针具的独立影响因素包括文化程度低、注射频率高、共用注射器／针头以外其他吸毒用具、有非固定性伴、有商业性伴、固定性伴注射吸毒、未使用安全套、未参与针具交换、招募年、招募地区。结论新注射吸毒者和长期注射吸毒者共用针具及无保护性行为比例均较高，长期注射吸毒者较新注射吸毒者有更多共用针具行为和无保护性行为，针对两类人群的干预应有不同侧重。Objective To examine the prevalence and correlates for needle-sharing among new and long-term injection drug users （IDUs） in Sichuan province, China. Methods Three consecutive cross-sectional surveys were conducted in 6 prefectures of Sichuan province, from 2003 to 2005. Questionnaire-based interviews provided information including socio-demographics, drug-use, sexual behaviors, and HIV-related services. Multivariable logistic regression methodology was used for data analysis. Results Of 3852 eligible participants, the rates of needle-sharing in the last 6 months for IDUs with a less than one year, one to three year, and more than three year injection history were 19.9%, 29.1%, and 36.3%, respectively. Needle-sharing for IDUs with a less than one-year injection history was independently associated with factors as ： being female, having minority background, higher frequency of injection, sharing injecting equipments, ever having had a non-regular sex partner, or a regular sex partner who injected drugs, never had a test on HIV, being recruited in 2005, and from Zigong prefectures of Sichuan. Needle-sharing for IDUs with a 1-3 year injection history were independently associated with receiving less education, having higher frequency of injecting behavior, sharing injecting equipments, ever having had a non-regular sex partner/a regular sex partner who injected drugs, ever having had unprotected sex with a non-regular sex partner, ever having had unprotected sex with a commercial sex partner or client, never attended skill training for HIV/STD prevention, being recruited in 2005 and 2004,and being recruited from Deyang, Zigong, and Liangshan prefectures. Needle-sharing for IDUs with a more than three-year injection history was independently associated with factors as： less education, higher frequency of injecting, sharing injecting equipment, ever had a non-regular sex partner, ever had unprotected sex with a non-regular sex partner, ever had unprotected sex with a commercial sex partner or client, having ha
