A Home-Based Intervention to Increase Physical Activity in Girls: The Fit ‘n’ Fun Dudes Program

There is a strong need to increase physical activity levels and healthy dietary behaviors among children due to rising levels of obesity in many countries worldwide. Following on from previous research on dietary change, the current study evaluated the effects of a home-based physical activity intervention with 32 girls (mean age, 10.6 ± 0.7 years) and their parents. During the 8-day intervention, children were introduced to fictional role models (the “Fit ‘n’ Fun Dudes”) and were given daily pedometer step targets to reach in order to receive small rewards. Pedometer measures were taken from children and parents in the experimental and control groups at baseline, during the intervention, and 12-week follow-up. Children in the experimental group were significantly more active than control children during the intervention on weekdays and weekend days (both p < 0.01). The effect remained at follow-up on weekend days (p < 0.05). Parents also increased their physical activity on weekend days. The intervention thus represents a promising strategy to increase physical activity in preadoles- cent girls and their parents.
