Effect of a governmentally-led physical activity program on motor skills in young children attending child care centers: a cluster randomized controlled trial

Table 3 Significant predictors of the primary and the secondary outcomes

Predictors ^a	% of child care centers ^b	Outcomes	Effect estimates of the predictors
			Δ of mean change (95% CI) ^c	p value
Information session with parents	72%	Motor skills (Global motor score)	1.15 (0.16 to 2.13)	p = 0.02
Free access to a movement space	48%	Motor skills (Global motor score)	0.92 (0.12 to 1.70)	p = 0.02
High motivation of the educators	59%	BMI (kg/m²)	−0.16 (−0.30 to −0.01)	p = 0.04
Training of additional educators	17%	BMI (kg/m²)	−0.26 (−0.50 to −0.01)	p = 0.04
Free access to a movement space	48%	Average PA (counts/min)	144 (41 to 248)	p = 0.006
Free access to a movement space	48%	MVPA (epochs/hours ≥ 420 counts)	9.4 (2.9 to 15.9)	p = 0.005
Purchase of mobile indoor equipment	69%	Average PA (counts/min)	170 (12 to 328)	p = 0.03
Purchase of mobile indoor equipment	69%	VPA (epochs/hours ≥ 842 counts)	4.0 (0.1 to 7.9)	p = 0.04

^a Feedback was obtained by the program coordinator from all 29 intervention child care centers at the end of the intervention. Only the significant predictors are shown in this table (5 out of 6).
^b Percentage of child care centers that provided the respective predictors.
^c The effect estimates describe the difference between the mean individual changes in the intervention child care centers fulfilling the respective criterion and the mean individual changes of the remaining intervention child care centers using mixed linear models and adjusting for the respective baseline values, age, gender and for the cluster factor child care center (i.e. the unit of randomization).
