OBJECTIVE To evaluate whether a child-centered physical activity program, combined with a parent-centered dietary program, was more efficacious than each treatment alone, in preventing unhealthy weight-gain in overweight children. STUDY DESIGN An assessor-blinded randomized controlled trial involving 165 overweight/obese 5.5- to 9.9- year-old children.(More)
