Physical activity and sedentary time
PA, time spent in MVPA, and sedentary behavior were measured by a triaxial accelerometer (Actigraph GT3X+, Ft. Walton Beach, FL). Children were measured 24 h/day for seven days. Measurements occurred for one week at baseline (before stenciling) and follow-up (six to eight weeks after stenciling). The child was outfitted with the accelerometer on an elasticized belt, on the right mid-axillary line by trained research staff and returned the accelerometers seven days later to the ECE program. During wear weeks, study staff checked accelerometry wear during school hours to assess for compliance. Based on previous work, [
