ABSTRACT=Background: The optimal balance of time spent on daily movement behaviours ("The Goldilocks Day") to preventassociated with childhood obesity remains unknown.Objective: To estimate the optimal durations of sleep, sedentary behaviour (SB), light physical activity (LPA), and moderate-to-vigorous physical activity (MPVA) for preventingassociated with excess adiposity in a paediatric population.Methods: Accelerometer-measured 24-hour movement behaviours were obtained from 659 Czech children and adolescents (8-18-year-olds). Adiposity indicators were body mass index z-score, fat mass percentage, fat-free mass index, and visceral adipose tissue. Excess adiposity was defined as exceeding the 85th percentile for an adiposity indicator. Compositional regression analyses were used investigate the associations between movement behaviours and adiposity indicators and estimating "The Goldilocks Day".Results: The movement behaviour composition was associated with visceral adipose tissue (Fdf1=3,df2=317 = 3.672, p = 0.013) and fat mass percentage (Fdf1=3,df2=289 = 2.733, p = 0.044) among children and adolescents. The Goldilocks Day consisted of 8.5h of sleep, 10.8h of SB, 3.9h of LPA, and 0.8h of MVPA among children and 7.5h of sleep, 12.4h of SB, 3.6h of LPA, and 0.5h of MVPA among adolescents.
