Rules utilised to guide the manual screening of the accelerometer data to identified non-wear time

Accelerometer administration was indicated if one of the following conditions were met:	The removal of an accelerometer was indicated if one of the following conditions were met:
a) If 60 min of consecutive 0’s (with the allowance of a 5-min interruption in the string of consecutive zero’s) in the VM axis precedes a VA count value of ≥760 cpm (i.e. light intensity PA) then this value is assumed to indicate the accelerometer being put on. Note, if another light count is identified in the following 5 min use the latter count as the on time.	a) If the 60 min following a VA count value of ≥760 cpm (i.e. light intensity PA) contains is a string of consecutive 0’s (with the allowance of a 5-min interruption in the string of consecutive zero’s) in the VM axis.
b) If 120 min of consecutive 0’s (with the allowance of a 5-min interruption in the string of consecutive zero’s) in the VM axis precedes a VA count value of ≥100 cpm (i.e. low intensity PA) then this value is assumed to indicate the accelerometer being put on. Note, if another count ≥100 cpm identified in the following 5 min use the latter count as the on time	b) If the 120 min following a VA count value of ≥100 cpm (i.e. low intensity PA) contains is a string of consecutive 0’s (with the allowance of a 5-min interruption in the string of consecutive zero’s) in the VM axis.
