Background: Schools are the most frequent target for intervention programs aimed at preventing child obesity; however, the overall effectiveness of these programs has been limited. It has therefore been recommended that interventions target multiple ecological levels (community, family, school and individual) to have greater success in changing risk behaviors for obesity. This study examined the immediate and short-term, sustained effects of the Switch program, which targeted three behaviors (decreasing children's screen time, increasing fruit and vegetable consumption, and increasing physical activity) at three ecological levels (the family, school, and community).

Research on parental monitoring of children's media use suggests parents can reduce the negative effects of media exposure on children, although this research is rarely conducted with elementary school children and leaves open questions about whether parents or children are better reporters. Participants were 1,323 children, their parents, and teachers. Parents and children reported on four aspects of monitoring for TV and video games: co‐using, limit setting on amount, limit setting on content, and active mediation. Parents gave much higher estimates than did children. Monitoring was moderated by child age, child sex, parent marital status, parent education, and parent income. Although parent‐ and child‐reported monitoring correlated rather poorly, both types were almost equally good predictors of children's screen time, media violence exposure, and teacher reports of school performance. When there were differences, the child reports tended to be slightly better predictors, demonstrating the validity of child reports of parental monitoring.

Although many of these young women were old enough to receive the vaccine without their parents' consent, perception of their mother's approval and mother-daughter communication about sex were important predictors of vaccination.

Parental monitoring of media has protective effects on a wide variety of academic, social, and physical child outcomes. Pediatricians and physicians are uniquely positioned to provide scientifically based recommendations to families; encouraging parents to monitor children's media carefully can have a wide range of health benefits for children.
