HIV risk behavior in drug users: increased blood "booting" during cocaine injection.

摘要: The practice of "booting" or "kicking," in which blood is drawn into the syringe and then injected, was assessed as a possible behavioral mechanism contributing to cocaine's association with increased human immunodeficiency virus (HIV) infection. Intravenous drug users (IVDUs) (N = 68) demonstrated (with an empty, needleless syringe) their usual style injection cocaine, heroin, speedball, random order. experimenter recorded procedures volumes at each step. Total number pumps were greater during simulated cocaine speedball use than heroin (p less .05); means for both 2- 3-fold heroin. Subjects also described booting behavior needle-sharing partners; percentage having partners who booted significantly .05). These findings indicate that associated (increased booting) more likely contaminate equipment blood. Thus, may warrant special attention AIDS prevention interventions risk assessments.
