  1. Abbreviations: IM independent mobility, IQR interquartile range, MVPA moderate-to-vigorous physical activity, PA physical activity, SD standard deviation.
  2. 1Highest education attainment was reported by one parent completing a survey.
  3. 2The distribution of MVPA was positively skewed; hence means, SD, medians and IQR are presented. MVPA was log-transformed prior to conducting independent t-test.
