  1. Note: Significant effects are indicated in bold: * P ≤ .05, **P ≤ .01, ***P ≤ .001. Reference categories for intervention is comparison; for attend organised activities is no attendance; for parents participate in sport is no participation; for space to ride bike at home is ample space; for sex is boys; for neighbourhood playground is no playground; for neighbourhood pool is no pool; for neighbourhood gym is no gym; for play equipment at home is ample equipment; for internet at home is yes connection in place; for parents achieve physical activity recommendations is not achieved. Number PCs in home.
  2. Child’s age, number of TV’s and PC’s at home, type of childcare attended, minutes in car (weekend) and number of siblings are reported as continuous variables where the average is centred around the grand mean (GM). The intervention β value represents the estimated difference in levels of sedentary time for the intervention centres against the comparison centres when all other parameters are included in the final model.
