  1. Group differences explored using two-factor ANOVAs.
  2. Mean (SE) presented.
  3. High CIM = high children’s independent mobility; low CIM = low children’s independent mobility.
  4. SES = socioeconomic status.
  5. aCIM difference (main effect, p < 0.05).
  6. bNeighbourhood difference (main effect, p < 0.05).
  7. cCIM x neighbourhood interaction (p < 0.05); significantly lower in those boys granted low CIM (p < 0.05).
  8. dCIM x neighbourhood interaction (p < 0.05); significantly higher in those boys granted low CIM (p < 0.05).
