Using wrist-worn consumer trackers to monitor kids' activity, calorie use, and sleep (ages 5–12)
Validity and Utility of Consumer-based Wearable Fitness Trackers to Monitor Free-Living Physical Activity Energy Expenditure and Sleep in Children 5-12 Years Old
This project sees whether everyday wrist devices like Fitbits or Garmins can accurately track physical activity, calories burned, and sleep in children ages 5 to 12.

What this research studies
You and your child would wear common wrist-worn fitness trackers during everyday life, typically for about a week, while researchers also collect comparison measurements using reference devices and short lab tests. The team will combine heart rate data and motion (accelerometer) signals from the consumer devices and compare them to established measurements such as chest-strap/ECG heart rate and controlled energy-expenditure assessments. Some visits may involve brief lab-based tasks to gather precise comparison data, and other data will be collected during usual daily routines at home and school. The goal is to see if these easy-to-wear devices give reliable, useful information about kids' activity and sleep patterns.
Who could benefit from this research
Good fit: Children aged 5–12 who can wear a wrist tracker for several days and attend brief lab or clinic visits are ideal candidates.
Not a fit: Children younger than 5, older than 12, or those who cannot tolerate wearing a wrist device or attending study visits are unlikely to benefit from participating.
Why it matters
Potential benefit: If successful, families and clinicians could use affordable wrist-worn trackers to monitor children’s activity, sleep, and calorie use more easily at home.
How similar studies have performed: Previous studies in adults and some clinical groups have shown promising agreement between consumer wearables and standard measures, but validation in 5–12 year-old children is largely untested.
