Stand-alone mass media campaigns to increase physical activity

The goal of the systematic review described in this summary was to determine the effectiveness of stand-alone mass media campaigns to increase physical activity at the population level. This systematic review is an update of a Community Guide systematic review and Community Preventive Services Task Force recommendation completed in 2001. The findings of this updated systematic review show that intervention effects, based wholly on self-reported measures, were modest and inconsistent. These findings did not lead the Task Force to change its earlier conclusion of insufficient evidence to determine the effectiveness of stand-alone mass media campaigns to increase physical activity.
