  1. CPM counts per min, NE non-established category by original authors, PA physical activity
  2. ^The sample size was composed of the sum of different studies selected to establish the validation protocol
  3. Data are described from 6329 participants who provided at least 1 d of accelerometer data and from 4867 participants who provided four or more days of accelerometer data
  4. Number of seconds that have elapsed between two consecutive measurements
  5. *These units were initially displayed in Epoch 15 s and transformed to Epoch 60 s in ActiLife
