Behaviors which entail high risk for human immunodeficiency virus (HIV) infection among intravenous drug users can be significantly reduced through educational intervention.
The educational intervention was conducted by a health educator in a one-on-one format and provided information about acquired immunodeficiency syndrome (AIDS) and strategies for reducing the risk of infection. Risk was assessed prior to the intervention and was compared to a follow-up assessment obtained approximately three months later (n = 322).
The percentage who reported using drugs intravenously decreased from 92.2 to 70.5, and the percentage who reported sharing syringes dropped from 67.4 to 24.3. Reductions of these and other high-risk behaviors were detected across various demographic subgroups, and analyses show that the impact of the intervention endured for several months.
The findings suggest that intravenous drug users conform to a model of rational choice when confronted with accurate information about the devastating consequences of HIV infection.
通过教育干预可显著减少静脉吸毒者中存在高感染人类免疫缺陷病毒（HIV）风险的行为。
由一名健康教育工作者以一对一的形式进行教育干预，提供有关获得性免疫缺陷综合征（AIDS）的信息以及降低感染风险的策略。在干预前评估风险，并与大约三个月后获得的随访评估结果进行比较（n = 322）。
报告静脉注射毒品的比例从92.2%降至70.5%，报告共用注射器的比例从67.4%降至24.3%。在不同人口亚组中均检测到这些及其他高风险行为的减少，分析表明干预的影响持续了数月。
研究结果表明，静脉吸毒者在面对有关HIV感染灾难性后果的准确信息时，符合理性选择模型。
