Abstract
Background: Media use is a known contributor to childhood obesity, but encouraging reductions in screen use only partially eliminates media influence. We tested a family-centered, media literacy-oriented intervention to empower parents and children 9-14 years to skillfully use media to reduce marketing influences, enhance nutrition knowledge, improve the selection of foods in the home environment, and improve fruit and vegetable consumption. Methods: A community-based, 6-U program included separate parent and youth (ages 9-14 years) sessions, each of which was followed by a session together in which skills from the individual sessions were reinforced. A pretest to posttest field test with control groups (N = 189, parent-child dyads) tested the intervention's efficacy. Results: Standardized mean differences from the multiple analysis of covariance tests showed that the intervention group demonstrated improvements on parents' use of nutrition labels (0.29), the ratio of healthy to unhealthy food in the home environment (0.25), youth's fruit (0.30) and vegetable (0.25) consumption, parent and youth media literacy skills, and family communication dynamics about food. The largest effects found were for negative parental mediation (0.48) and parents' report of child-initiated discussion (0.47). Consistent but weaker results were revealed for Latinx families. Conclusions: This family-centered approach helped family members practice using media together to make better nutrition decisions without depending on the ability of parents to limit media use. It successfully addressed the often-negative impact of the media on behaviors that increase obesity risk while also cultivating the potential for media to provide useful information that can lead to behaviors that decrease obesity risk.
