Data represent the mean ± standard deviation. Significance was set at 0.05. PA = physical activity; PA-EPAO = Physical Activity Environment and Policy Assessment Observation; MVPA = moderate to vigorous physical activity
^a% time is calculated from total minutes of measured activity. Approximate minutes are reported in parentheses
^bFor high-scoring centers (PA-EPAO ≥ 11.2 at baseline), n = 120 at baseline, n = 148 at 6-month, n = 137 at 12-month
^cFor low-scoring centers (PA-EPAO < 11.2 at baseline), n = 111 at baseline, n = 176 at 6-month, n = 155 at 12-month
^dOnly children who were present for both the baseline and 12-month measurement were included in the Δ analysis; n = 66 for combined centers, n = 30 for high-scoring centers (PA-EPAO ≥ 11.2 at baseline), and n = 36 for low-scoring centers (PA-EPAO < 11.2 at baseline)
*p-values for total minutes and sedentary, light, and MVPA percentages represent differences between baseline and 12-month 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
