Summary
Social network changes among injection drug users (IDUs) significantly predict HIV risk behaviors. Network instability, indicated by member movement, is linked to increased risky injection drug use, suggesting resource instability.
Area of Science:
- Public Health
- Sociology
- Epidemiology
Background:
- HIV risk behaviors vary significantly among injection drug users (IDUs).
- Social network structures are a key factor influencing these behavioral variations.
- IDU social networks may be dynamic due to the inherent instability in their lives.
Purpose of the Study:
- To examine changes in individual behavior and social network characteristics over time among IDUs.
- To investigate the relationship between network dynamics and HIV risk behaviors.
Main Methods:
- Longitudinal study of IDU social networks in Chicago and Washington, DC.
- Analysis of standard network measures (density, size) and specific network change measures (member movement).
Main Results:
- Standard network measures showed minimal change over time.
- Significant movement of members into and out of networks was observed.
- Movement of members into a network was a significant predictor of increased risky injection drug use.
Conclusions:
- IDU social networks are dynamic, characterized by member turnover.
- Network instability, evidenced by member movement, is associated with higher HIV risk behaviors.
- This network dynamism may reflect an unstable resource base within IDU communities.
