静脉吸毒人员共用针具行为调查

目的了解静脉吸毒人群的针具共用情况并探索可能的影响因素。方法采用横断面研究方法于2011年5-6月对广东省某戒毒所内静脉吸毒人员进行一对一的问卷调查,调查内容包括一般人口学信息、吸毒相关行为、性行为及艾滋病综合防治知识。结果调查的267名男性静脉吸毒人员的平均年龄为(38±6.1)岁,首次注射吸毒的平均年龄为(28±6.9)岁。30.71%的被调查者曾有过共用针具行为,被调查者使用的毒品种类主要是海洛因。Logistic回归分析表明,与别人一起吸毒(OR=3.62,95%CI=1.77-7.37)以及共用过辅助器具者(OR=13.48,95%CI=6.66-27.27)是共用针具的危险因素。结论共用针具行为普遍存在于静脉吸毒人群中,相关部门应采取有效管理措施,以减少该人群中高危行为的发生。

Needle sharing and its influential factors among intravenous drugs users

Objective To understand the status and explore influential factors for needle sharing among intravenous drug users. Methods A cross-sectional survey among intravenous drug users in a rehabilitation center in Guangdong province was carried out during May and June 2011.Questionnaire-based interviews were conducted to collect information including socio-demographics,drug use patterns,sexual behaviors and HIV-related knowledge. Results Of 267 eligible participants, the mean age was(38±6.1).The mean initial age of injecting drug was (28±6.9). 30.71% of them reported having shared needles and heroin was the most widely used drug among them. The Logistic regression showed that not injecting alone(OR=3.62,95%CI=1.77-7.37) and sharing injection paraphernalia (OR=13.48,95%CI=6.66-27.27) were the risk factors for needle sharing. Conclusions Needle sharing is not rare among intravenous drug users. Targeted effective measures should be carried out to reduce those risky behaviors.
