Label

Pwear wkend 18-00

Description

Phase 2 data. Number of valid hours worn during free-living in the morning quadrant (between 18:00-00:00) on weekend days (Saturday and Sunday); across the full data file (consolidated). 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. 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)). In instances when the imputed data has been used in the consolidated variable; this will have a binary flag (imputed = 1). This variable indicates the total wear time between 18:00-00:00 on weekend days; across the whole data file; in hours.
