Measurement of movement behaviour
The movement behaviours SB, low-intensity physical activity (LIPA) and MVPA were measured by the triaxial accelerometer ActiGraph GT3X+ (ActiGraph, Pensacola, FL, USA). Procedures for data collection and processing have been reported elsewhere [The day was partitioned into absolute and relative time spent in SB, LIPA and MVPA based on vertical axis cut-points of the accelerometers. SB was defined as < 100 counts/min [
