Systemic reviews of behavioural interventions for reducing the risk of HIV and AIDS: are we getting the evidence?

Abstract

Social interventions aim to change risk behaviours or decrease incidence rates of HIV, and also include explicit and direct attempts to change peer or community norms related to HIV risk. These interventions, while they may use individual or small group approaches, emphasize peer influence and community-level approaches, such as engaging key opinion leaders like educators, and mobilizing the community to support HIV risk reduction behaviors. This category also includes any intervention aimed at changing environmental factors or structures related to HIV risk.
