The study sample

The Study Sample

  • 875 IDUs from 24 neighborhoods in three Northeast cities.

  • The data were collected through face-to-face interviews using a survey instrument of Syringe Access, Use & Discard Assessment (SAUDA) from December, 1999 through September, 2001.


Measures i

Measures I

  • The General Attitude of Other IDUs in the Neighborhood towards Drug-Related HIV Risk Behavior

    • Measured by 8 items of drug-related HIV risk & protection behavior.

    • Participants rated the general attitude of other IDUs in their neighborhoods regarding each item on a 5-point scale.

    • A General Attitude variable was computed based on the mean scores of the 8 items.


Measures ii

Measures II

  • Drug Injection Paraphernalia Sharing

    • Indicated by three dichotomous variables of Syringe Sharing, Water Sharing, and Cooker/Cotton Sharing

    • The three variables were computed based on the number of times in the past 30 days that a participant used a syringe, water to mix up drug, a cooker, or a cotton that had already been used by another IDU.

Summary of the findings

Summary of the Findings

  • The prevalence of injection paraphernalia sharing among IDUs varied by neighborhood.

  • IDUs who did share reported a more accepting attitude towards risky behavior from other IDUs in their neighborhoods.

  • IDUs’ perception of the attitude of other IDUs in their neighborhoods towards risk behavior was significantly associated with their own recent sharing behavior.


Implications of the findings

Implications of the Findings

  • Other IDUs’ attitude towards drug-related HIV risk behavior is an important factor in determining an IDU’s own HIV risk behavior.

  • AIDS/HIV prevention/education that target on not only individual injection drug users but also local IDUs group and their peer norms should be more effective.
