  1. Results of Mixed Linear Regression adjusted for asex, parental education, baseline value, bmonitor wear time cand MVPA
  2. b = Regression coefficient (beta), p = between intervention and control groups, CI = 95 % confidence interval
  3. TPA total physical activity, cpm counts per minute, MVPA moderate to vigorous physical activity
  4. Subjects are dependent observations between T1 and T2 and between T1 and T3
