Summary
Incentive programs encouraging children to meet step goals significantly increased daily steps. Future trials need higher targets and longer follow-up to confirm health benefits.
Area of Science:
- Pediatric health
- Behavioral science
- Public health interventions
Background:
- Childhood obesity is a growing concern, necessitating effective interventions to promote physical activity.
- Understanding the impact of incentive-based programs on children's activity levels is crucial for public health strategies.
Purpose of the Study:
- To assess the effectiveness of an incentive-based intervention designed to boost physical activity and fitness in children.
- To evaluate the intervention's impact over a 9-month period using a cluster randomized controlled trial design.
Main Methods:
- A 9-month cluster randomized controlled trial involving children aged 6-12 years.
- The intervention group received incentives for meeting pedometer-determined step targets and participated in structured weekend outdoor activities.
- Outcomes measured included pedometer steps, 6-minute walk test, body mass index, and parent-reported Pediatric Quality of Life Inventory.
Main Results:
- Children in the intervention group achieved significantly more steps daily, on weekdays, and on weekends compared to the control group.
- Activity trajectories revealed groups that increased but didn't sustain activity, met targets, and surpassed targets.
- Trends indicated improvements in 6-minute walk test times and quality of life scores, though not statistically significant.
Conclusions:
- Incentives effectively increased children's daily step counts, demonstrating a positive impact on physical activity.
- While not statistically significant, trends suggest potential benefits in fitness and quality of life.
- Future research should incorporate higher step targets and extended follow-up periods to establish long-term health effects.
