* Sedentary behaviour was defined as: levels 1 & 2 in OSRAP 5 point scale [47]; levels 1 & 2 in CARS 5 point scale [50]; CSA/MTI accelerometry cut-point of <1100 cpm [25, 26, 31]; ActiGraph age-specific cut-points corresponding to ≤1.4 METs (approx. 100 cpm) [15]; ActiGraph age-specific cut-points between 1456 cpm (3 year olds) and 1596 (5 year olds) [27, 28]; ActiGraph cut-point <150 cpm [30]; Actical cut-point of <200 cpm [29, 49].
