  1. The network approach and interventions to prevent HIV among injection drug users.

    Article - En anglais


    To review human immunodeficiency virus (HIV) risk reduction interventions among injecting drug users (IDUs) that have adopted a network approach.


    The design and outcomes of selected network-based interventions among IDUs are reviewed using the network concepts of the dyad (two-person relationships), the personal risk network (an index person and all of his or her relationships), and the « sociometric » network (the complete set of relations between people in a population) and community.


    In a dyad intervention among HIV-serodiscordant couples, many of which included IDUs, there were no HIV seroconversions.

    Participants in personal risk network interventions were more likely to reduce drug risks and in some of these interventions, sexual risks, than were participants in individual-based interventions.

    Sociometric network interventions reached more IDUs and may be more cost-effective than individual-based interventions.


    Network-based HIV risk reduction interventions among IDUs, and others at risk for HIV, hold promise and should be encouraged.
