Description

DataType
calibration method applied
Phase 2 data. 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).
Text
calibration type
Phase 2 data. 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.
Text
Device serial number
Phase 2 data. Device serial number of monitor used for data collection.
Integer
Proportion time spent >= 0 milli-g
Phase 2 data. Proportion of time spent above >=0 milli-g (sleep imputed). The acceleration value is calculated as ENMO (euclidean norm minus one). 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.

Flag to indicate imputed data used
Phase 2 data. 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). These variables are indicated in the label with consolidated.

Flag for data missing Pwear
Phase 2 data. Flag variable that can be used to condition the data on to protect against potential bias caused by data missing at certain times of day (i.e. missing in certain Pwear quadrants). It is advisable to ensure that data are distributed across the 24-hour period and use an inclusion criteria relating to compliance. This variable indicates: 0 = Insufficient wear time (Pwear <48 hours and three Pwear_quads <9 hours wear); 1 = Pwear >=48 hours and all four Pwear_quads >=9 hours; 2 = Pwear >=48 hours and three Pwear_quads >=9 hours (<9 hours in morning quad (midnight-6am)).

Threshold set still bout detection
Phase 2 data. Threshold set for still bout detection (milli-g). Still bouts are flagged during processing as periods of time where the standard devigorous intensity activitytion of each of the three axes (x; y and z of the raw; triaxial accelerometry data) fall below this threshold.

Pwear afternoon imputed
Phase 2 data. Number of valid hours worn during free-living in the afternoon quadrant (between 12:00-18:00); across the full data file (sleep imputed). Non-wear periods are calculated as periods of time >=60 mins where the standard devigorous intensity activitytion 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 12:00-18:00; across the whole data file; in hours.
