Background: Interventions to increase children’s physical activity have had limited success.
One reason may be that children and their parents overestimate children’s levels of physical
activity, although there are few data on this topic.
Purpose: This study aimed to assess awareness of physical activity levels among British
school children aged 9–10 years and their parents.
Methods: Physical activity was measured by accelerometer in a cross-sectional study of 1892
