We leveraged a community-school district-university partnership in Sarasota County, Florida, in May of 2005 to assess physical activity levels among tweens (youth aged 9-13 years) and to measure the relationship between tweens' awareness of the Centers for Disease Control and Prevention's VERB program and participation in physical activity, using a minimally obtrusive survey. After surveying participating schools (4 elementary schools and 3 middle schools), we obtained 1,407 responses from children in grades 5 through 7. In all, 83.1% of students met the federal recommendation for daily participation in vigorous-intensity physical activity (VPA), and 58.6% had tried a new game or sport within the previous 2 months. Mean number of days in the previous week engaging in VPA was significantly higher (P < .001) for ...
