Table 4 Mean difference between observed and predicted time in each activity intensity

From: Feasibility and validity of accelerometer measurements to assess physical activity in toddlers

OSRAC-P activity intensity level Observed time (mean min ± SD) Cut point Mean difference (min) ULOA (min) LLOA (min)
Stationary and motionless to stationary with movement of limbs or trunk behavior (sedentary behavior) 68.5 ± 37.6 Pate (≤ 37) 1.5 14.0 -11.0
   Sirard 3-year olds (≤ 301) -11.5 2.1 -25.0
   Van Cauwenberghe (≤ 372) -13.0 0.6 -26.9
Slow, easy movement (light physical activity) 49.4 ± 21.2 Pate (38 - 419) -3.0 8.2 -14.2
   Sirard 3-year olds (302 - 614) 8.2 18.6 -2.2
   Van Cauwenberghe (373 - 584) 9.9 19.8 -0.1
Moderate to fast movement (moderate-to-vigorous physical activity) 18.1 ± 16.3 Pate (≥ 420) 1.5 8.2 -5.2
   Sirard 3-year olds (≥ 615) 3.3 0.5 -3.9
   Van Cauwenberghe (≥ 585) 3.2 10.4 -4.1
