| 摘 要： | 目的:了解四川省西昌市吸毒人群初次共用注射器具的发生情况及其影响因素。方法:于2004年5-7月,从社区中招募吸毒人员,调查其社会人口学、初次吸烟、饮酒和吸毒相关行为特征情况。结果:在调查的451名吸毒人员中,82·04%(370/451)在调查前注射毒品;50·33%(227/451)曾经共用过注射器具。从初次吸毒到初次共用注射器具静脉注射毒品的发生率为9·69/100人年,多因素Cox比例风险模型分析结果显示,与初次共用注射器具的发生相关的变量为男性(危险率比值为1·80;95%可信区间为1·11-2·91)、初中以下文化(危险率比值为1·48;95%可信区间为1·14-1·94)和15a以前开始吸烟(危险率比值为1·40;95%可信区间为1·06-1·84)。从初次静脉注射毒品到初次共用注射器具注射毒品的发生率为34·12/100人年,多因素Cox比例风险模型分析结果显示,与初次共用注射器具发生相关的变量为男性(危险率比值为1·92;95%可信区间为1·20-3·06)和初中以下文化(危险率比值为1·31;95%可信区间为1·00-1·71)。结论:西昌市吸毒人群中男性、文化程度低和吸烟年龄早是其初次共用注射器具发生的影响因素。 |

| Abstract: | Objective:To investigate factors associated with initial sharing of injection equipment among drug users in Xichang county,Sichuan province. Methods:During May to July 2004,a community- based survey was conducted to collect the demographic characteristics,smoking,alcohol drinking and drug use related risk behaviors before initial drug use. Results:A total of 451 drug users were interviewed. Of all the subjects,82.04% (370/451) injected drugs and 50.33% (227/451) shared injection equipment in the past. The average incidence was 9.69/100 person years from initial drug use to the first sharing of injection equipment,and multivariate Cox proportional hazard regression model indicated that male (HR:1.80;95%CI:1.11-2.91),elementary or less educational level(HR:1.48; 95%CI: 1.14-1.94) and smoking before 15 years old (HR:1.40;95%CI:1.06-1.84)were independently associated with the first sharing of injection equipment. The average incidence was 34.12/100 person years from initial drug injection to the first sharing of injection equipment,and multivariate Cox proportional hazard regression model indicated that male (HR: 1.92;95%CI:1.20-3.06) and elementary or less educational level(HR:1.31;95%CI:1.00-1.71) were independently associated with the first sharing of injection equipment. Conclusion: Male,less education and smoking are the factors associated with initial sharing of injection equipment among drug users. |
