into measures of metabolic equivalents (METs) expenditure that reflect thresholds (cut-points) for specified levels of activity ( Watson, Carlson, Carroll, & Fulton, 2014 ). Cut-points are numerical values for the acceleration of movement intensity (activity counts) that reflect thresholds in the

monitor 29 that measures accelerations throughout the day, which are expressed as activity counts. The activity counts were summed over a 60-second epoch and categorized as light, moderate, vigorous, or very vigorous activity using previously validated thresholds. 29 This data was further extrapolated

This is a uniaxial accelerometer recording acceleration signals along the vertical axis to generate activity counts corresponding to activity intensity. 19 Recordings of physical activity in the present study were performed during the whole autumn school term. Children were instructed to wear the

more. Activity counts were converted into minutes of moderate- to vigorous-intensity PA per day based on the cutoffs suggested by Fredman, Bertrand, Martire, Hochberg, and Harris ( 2006 ). Covariates Several demographic and health-related factors were measured and controlled for in the analyses. The
