Substituting device-measured sedentary time with alternative 24-hour movement behaviours: compositional associations with adiposity and cardiometabolic risk in the ORISCAV-LUX 2 study

Table 2 Arithmetic and geometric compositional means for the four- and five-part time-use compositions

	Arithmetic mean		Geometric mean
	Min/d	%	Min/d	%
Four-part composition
Sleep period	463.4	32.2	467.6	32.5
Sedentary time	727.9	50.5	735.6	51.1
Light PA	162.7	11.3	159.3	11.0
MVPA	86.0	6.0	77.5	5.4
Five-part composition
Sleep period	463.4	32.2	483.6	33.6
Prolonged sedentary time	442.2	30.7	432.7	30.0
Non-prolonged sedentary time	285.7	19.8	278.9	19.4
Light PA	162.7	11.3	164.7	11.4
MVPA	86.0	6.0	80.1	5.6

Geometric means are the most appropriate measure of central tendency for compositional data. The means of each contributing behaviour were rescaled so that all parts collectively summed to 1440 min.
