title: Impact of California Children's Power Play! Campaign on Fruit and Vegetable Intake and Physical Activity among Fourth- and Fifth-Grade Students.
abstract: Examine the impact of the Children's Power Play! Campaign on fruit and vegetable (FV) intake and physical activity (PA).
  
  
  
  Study design was a cluster randomized, controlled trial.
  
  
  
  Forty-four low-resource public schools in San Diego County, California, were included in the study.
  
  
  
  Study subjects comprised a total of 3463 fourth/fifth-graders (1571 intervention, 1892 control), with an 86.9% completion rate.
  
  
  
  Throughout 10 weeks, activities were conducted during/after school, including weekly FV/PA lessons and PA breaks; biweekly classroom promotions/taste tests; posters displayed in/around schools; and weekly nutrition materials for parents.
  
  
  
  Self-reported FV intake (cups/d) and PA (min/d) were collected at baseline and follow-up using a diary-assisted, 24-hour dietary recall and Self-Administered Physical Activity Checklist.
  
  
  
  Multivariate regression models adjusted for demographics and cluster design effects were used, with change as the dependent variable.
  
  
  
  Intervention children, compared with controls, showed gains in daily FV intake (.26 cups, p < .001) and PA time at recess/lunch (5.1 minutes, p = .003), but not total daily PA minutes.
  
  
  
  Power Play! can help schools and community organizations improve low-income children's FV intake and PA during recess/lunch.
