  1. Note: Significant effects are indicated in bold: * P ≤ .05, **P ≤ .01, ***P ≤ .001. Reference categories for intervention is comparison; for parents participate in sport is no participation; for neighbourhood pool is no pool; for parents gender is male; for parents achieve physical activity recommendations is not achieved; for space to ride bike at home is ample space; for eat meals at TV is does not eat at TV. Type of childcare attended and minutes in car (weekday) are reported as continuous variables where the average is centred on 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.
