Interpretive Summary: Understanding physical activity is the key to fighting childhood obesity. The objective of this study was to examine the feasibility of using certian wearable devices to measure physical activity among children. A qualitative study was conducted with 25 children aged 7 to 10 yearsto assess acceptability and compliance of wearable activity devices in this age group .During March through August 2012. children participated in a 4-week study of 3 acceleraometer models and a heart rate monitor. Children were asked to use devices each week for 7 consecultive days. Children and their parents completed structured interviews after using each device; they also completed final exit interviews. The wrist-worn Polar Active was the device most preferred by children and was associated with the highest level of compliance. Devices that are confortable to wear, fit properly, have engaging features, and are waterproof increase feasibility and are associated with higher levels of compliance. The wrist-worn device was the most feasible for measuring physical activity among children aged 7 to 10 years. These findings will inform researchers in selecting tools for measuring children's physical activity.
