  1. Abbreviations: Sit = Sitting time; Stand = Standing time; Step = Stepping time; b = point estimate of the regression coefficient; 95 % CI = 95 % confidence intervals; P = within-day period
  2. aModel: Adjusted for sex, year of school, day of measurement (e.g. Monday, Tuesday, etc.), waist circumference, wear time in a given period, and average person-level activity and/or sitting time (as appropriate) per period and per day
  3. Note: b indicates the association within-days for every additional minute of activity in one period and activity in the following period
