All values are mean (SD) unless otherwise stated. All accelerometer variables are adjusted for wear time; ST: Sedentary time; LPA: Light physical activity; MVPA: Moderate-to-vigorous physical activity; BST: Breaks in sedentary time; PA: physical activity; Meeting WHO PA guidelines: accumulating 150 min/week of moderate physical activity or 75 min/week of vigorous physical activity or equivalent combination of moderate and vigorous physical activity.
