Impact of accelerometer epoch length on physical activity and sedentary behaviour outcomes for preschool-aged children - ARCHIVED

The Canadian Health Measures Survey uses accelerometry to collect physical activity and sedentary behaviour data. Between cycles 2 and 3, a transition was made from 60-second to 15-second epochs in accelerometry data for children aged 3 to 5. This study examines the impact of epoch length on physical activity and sedentary behaviour outcomes for children in this age range.
