Fit "N" Cool Kids: The Effects of Character Modeling and Goal Setting on Children's Physical Activity and Fruit and...

Efforts to decrease the risk of overweight and obesity should focus on children's physical activity (PA) and fruit and vegetable (FV) consumption. Within school-based interventions, there is insufficient evidence on the effectiveness of the use of character modeling and goal setting to determine changes in step counts, MVPA, and FV consumption. Study participants were 187 students in grades 4 and 5 from 2 Title 1 elementary schools in the Southwest United States. The intervention was a quasi-experimental character modeling and goal setting program. New Lifestyles NL-1000 activity monitors were used to assess number of steps taken and MVPA by the participants. Fruit and vegetable consumption was measured by direct observation. School day steps, MVPA, and FV consumption were recorded at baseline, intervention, and during a 10-week follow-up. There were not differences between groups at baseline. Steps and MVPA were statistically significantly (P < .05; Δ = ~2500 steps and ~5 minutes of MVPA) greater in the intervention compared with the control group over time. Fruit and vegetable consumption was not significantly (P = .308) greater in the intervention compared with the control group over time. Students in the intervention school were significantly more active than students in the control school during the intervention phase and at follow-up. The findings reported here would suggest that character modeling and goal setting can increase PA among elementary aged children but did not increase FV consumption.
