Day-dependent step-count patterns and their persistence over 3 years in 810-year-old children: The LOOK project

Physical activity in children is known to be generally lower at weekends but whether systematic day-to-day differences exist throughout the week is unclear. Aim: To determine if weekly patterns of pedometer-assessed physical activity (PPA) exist in elementary school-aged Australian boys and girls and whether they persist over 3 years. Subjects and methods: Seven-day pedometer measurements were recorded from 389 boys and 387 girls of initial age 8.0 (SD 0.3) in three successive years during spring. General linear mixed modelling was used to investigate patterns and the persistence of PPA.
