Accelerometry measured ethnic differences in activity in rural adolescents.

ABSTRACT:

Background

To determine if there are differences in time spent in physical activity and sedentary behavior between rural African American and Caucasian children.

Methods

Children wore accelerometers for 3 weekdays. The students were randomly selected from a larger sample of children participating in a weight gain prevention intervention.
