Note These recommendations should be considered with caution. We strongly recommend reading Sect. 4 for an understanding of the specific considerations for each age group
There are no algorithms currently available to estimate sleep-related behaviors from data obtained from hip-worn devices
Criterion that could highly affect the output. In these cases, when estimations of PA, PAEE or sleep are the variables of interest, the same criterion as selected in the validation study is recommended. If acceleration metrics are the variables of interest (e.g., counts), the recommendation is provided in this table
There is a need to thoroughly test this criterion
Number of hours per awake period in a day
Citation of the study in which the cutpoints or algorithms were validated
Cutpoints are specified in Table 5
