Label

% tme spent <= 1.5METstd grp calbiration

Description

Phase 2 data. Fraction of time spent < = 1.5 MET (std); acceleration and heart rate using group calibration; This variable uses the resting metabolic rate calculation as defined in STANDARD_MET; same for every individual. Where possible; a specific group equation is derived for that study using data from the IC tests. Where this is not possible; the most appropriate equation from another study will have been applied in the calculation of the group estimated physical activity energy expenditure results. Equation used is indicated in GROUP_EQUATION. Present for all those who have a valid free-living file i.e file present; no corruptions deemed to affect combined acc and heart rate estimate and >20hrs Pwear(Measured/Derived from or related to Acitheart Monitor/Data )
