Active Early: one-year policy intervention to increase physical activity among early care and education programs in Wisconsin

Table 4 Observed minutes of teacher-led^a physical activity and play time outside for all centers combined and by high and low scoring centers at baseline

Observed Time (min)	Baseline	6-month	12-month	Δ Baseline to 12-month	p-value*
Teacher-led PA	30.9 ± 22.7	76.8 ± 38.1	82.3 ± 40.7	51.3 ± 41.3	<0.01
High scoring centers	39.3 ± 21.9	93.9 ± 33.4	90.3 ± 36.4	51.0 ± 36.8	NS
Low scoring centers	22.6 ± 21.1	59.7 ± 35.9	74.2 ± 45.1	51.6 ± 47.3	NS
Outside time	84.5 ± 49.3	107.8 ± 57.3	84.2 ± 47.3	−0.25 ± 56.7	0.98
High scoring centers	79.2 ± 61.9	107.8 ± 56.7	92.0 ± 54.6	12.8 ± 72.6	<0.01
Low scoring centers	89.7 ± 35.2	107.7 ± 61.0	76.4 ± 39.9	−13.3 ± 33.3	<0.01

Data represent the mean ± standard deviation in minutes. Significance was set at 0.05. PA physical activity, PA-EPAO physical activity environment and policy assessment observation tool
^aTeacher-led physical activity refers to structured activity. Outside play time refers to unstructured activity or activity that is not teacher initiated
*p-values for all centers combined for Teacher-led PA and outside play time (bold) represent test for differences between baseline and 12-month observations analyzed by t-test; p-values for high (PA-EPAO ≥ 11.2) and low (PA-EPAO < 11.2) centers at baseline represent mean differences between those two groups by PROC GLM using Tukey’s adjustment for multiple comparisons
