  1. Changes in network characteristics and HIV risk behavior among injection drug users.

    Article - En anglais

    Studies indicate that HIV risk behaviors vary greatly among injection drug users (IDUs).

    The source of such variation is often ascribed to individual differences, but much of it is due to how IDUs are grouped into social networks.

    Nevertheless, given the turbulent and uncertain lives led by many IDUs, it would not be surprising if their social networks changed substantially over time.

    We used data from a study of the social networks of IDUs in Chicago and Washington, DC, to examine changes in individual behavior and network characteristics over time.

    The results indicated few changes in standard network measures, such as density of ties or network size, over time.

    However. specific network change measures, that is, indicators of movement into and out of networks, showed significant movement of network members over time.

    Moreover, movement of members into a network significantly predicted a higher likelihood of risky injection drug use over time.

    We suggest that these movements are indicative of a lack of a stable resource base among IDU networks.
