  1. aBias-corrected and accelerated bootstrapping was applied to bivariate Pearson’s correlation analyses to generate standardised beta coefficients (β) and 95% confidence intervals (lower to upper). Sedentary, standing and stepping time were calculated as percentages of activPAL3μ wear time for use in bivariate Pearson’s correlations
  2. b* = Significant association (95% confidence intervals derived from bootstrapping did not cross zero)
