Note: Values are expressed as standardised association (β) and significance values (p) in parentheses. ‘p’ is set at a significance level of less than 0.5. Abbreviations: LIT = sitting interrupted by light intensity activity walk breaks, MIT = sitting interrupted by moderate intensity stair climbing breaks, SIT = uninterrupted sitting.
