ax_calibration_method_12m
Calib method 12m
Calibration method applied to data file. Offset and scale with temperature (which uses both an offset and scaling factor for each axis) or offset only with temperature (which uses just the offsets). 12-month measure.

ax_calibration_method_6m
Calib method 6m
Calibration method applied to data file. Offset and scale with temperature (which uses both an offset and scaling factor for each axis) or offset only with temperature (which uses just the offsets). 6-month measure.

ax_calibration_method_bl
Calib method bl
Calibration method applied to data file. Offset and scale with temperature (which uses both an offset and scaling factor for each axis) or offset only with temperature (which uses just the offsets). Baseline measure.
Text
ax_calibration_type_12m
Calib type 12m
Calibration type used. Single file; multi file or fail. Single file calibration uses the calibration factors from the file itself. Multi-file calibration uses calibration factors from all files in the processing database (all datasets) that have used the same device. Fail indicates that the file has failed calibration and therefore the results are unusable and have been set to missing. 12-month measure.

Binary flag (imputed=1) indicates if the imputed data has been used in the consolidated variables for this dataset. In some instances where data is likely to be excluded non-randomly; imputation may be required. Most commonly this is observed with night recording with systematic non-adherence to wearing a monitor during sleep in a 24-hr protocol. The Pwear variable has been set to 1 during the night (midnight-6am); to impute sleep when the monitor was flagged as non-wear during those times. These data are imputed proportional to the amount of days the monitor was worn so as not to inflate wear-time over the recording period. During the creation of the consolidated variables; the standard output variables (means and intensity categories) have been updated with the imputed data if certain criteria are met (limited night data i.e. include=2).

This imputed variable is derived from imputing sleep data if certain criteria of limited night data are met (i.e. not worn between 00:00-06:00). Pwear is set to 1 during these hours to impute sleep if not worn. This variable indicates the total wear time between 12:00-18:00 on weekdays; across the whole data file; in hours. 12-month measure.

Number of valid hours worn during free-living between 16:00-17:00; across the full data file (no sleep imputed / standard output). Non-wear periods are calculated as periods of time >=60 mins where the standard deviation of each of the three axes (x; y and z of the raw; triaxial accelerometry data) is <13mg. Both of these criteria are used to determine wear probability. This is the standard output (original) variable meaning no sleep imputation has been done. This variable indicates the total wear time between 16:00-17:00; across the whole data file; in hours. Baseline measure.

Non-wear periods are calculated as periods of time >=60 mins where the standard deviation of each of the three axes (x; y and z of the raw; triaxial accelerometry data) is <13mg. Both of these criteria are used to determine wear probability. This imputed variable is derived from imputing sleep data if certain criteria of limited night data are met (i.e. not worn between 00:00-06:00). Pwear is set to 1 during these hours to impute sleep if not worn. This variable indicates the total wear time between 00:00-06:00 on weekend days; across the whole data file; in hours. 6-month measure.

This imputed variable is derived from imputing sleep data if certain criteria of limited night data are met (i.e. not worn between 00:00-06:00). Pwear is set to 1 during these hours to impute sleep if not worn. This variable indicates the total wear time between 06:00-12:00; across the whole data file; in hours. 12-month measure.

Pwear consolidated weekday bl
Number of valid hours worn during free-living over weekdays (Monday-Friday); across the full data file (consolidated). Non-wear periods are calculated as periods of time >=60 mins where the standard deviation of each of the three axes (x; y and z of the raw; triaxial accelerometry data) is <13mg. Both of these criteria are used to determine wear probability. Consolidated variable derived from either the original data (i.e. non-imputed) or imputed data where sleep has been imputed if certain criteria of limited night data are met (i.e. where inclusion criteria ‘include’ = 2 (for details of inclusion criteria, see 'include' variable)).
