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

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

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

 Low scoring centers 22.6 ± 21.1 59.7 ± 35.9 74.2 ± 45.1 51.6 ± 47.3
Outside time 84.5 ± 49.3 107.8 ± 57.3 84.2 ± 47.3 −0.25 ± 56.7 0.98

  1. 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
  2. aTeacher-led physical activity refers to structured activity. Outside play time refers to unstructured activity or activity that is not teacher initiated
  3. *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
