  1. PA physical activity; SB sedentary behaviour; CPM counts per minute; MVPA moderate or vigorous physical activity
  2. aBRHS men who met the inclusion criteria: had a self-reported PA score and a valid week (≥3 days of ≥600 minutes) of accelerometer data
  3. bMean (SD) total time watching television, min/day
  4. cCoefficients are mean (95 % CI) minutes per day spent in each level of activity, adjusted for wear time, day order, season and region using random effects model.
  5. dMean (SD) total SB score (watching television + using a computer + reading + sitting in a car), min/day
  6. eSedentary 60+ (total number of minutes of SB in bouts lasting ≥ 60 minutes)
