HIV prevention mass media campaigns

We have just published a systematic review of studies to evaluate HIV prevention mass media targeting MSM. The review included 16 reports from 12 studies which examined campaigns which aimed to provide MSM with information to prevent HIV transmission and increase motivation and norms towards precautionary behaviours. We conclude the limitations of mass media should be recognised and campaigns supplemented by additional interventions may be better-suited to these goals. .
