Table 3 Effect of introducing the Daily Mile on outcomes assessed immediately after the end of the intervention period

From: The Daily Mile makes primary school children more active, less sedentary and improves their fitness and body composition: a quasi-experimental pilot study

Outcome Difference in change between schools after correction for age, gender and age*gender Difference in change between schools after correction for age, gender, age*gender and SIMD
Mean (95% CI) SMD p value Mean (95% CI) SMD p value
Mean MVPA per day (min) 9.1 (5.1 to 13.2) 0.407 0.027 9.5 (5.4 to 13.5) 0.422 0.021
Mean sedentary time per day (min) -18.2 (−10.7 to −25.7) 0.437 0.017 -18.1 (−10.6 to − 25.6) 0.435 0.018
Total shuttle distance (m) 39.1 (21.9 to 56.3) 0.236 0.037 37.2 (20.1 to 54.3) 0.225 0.046
Sum of skinfolds (mm) -1.4 (−2.0 to −0.8) 0.246 0.034 -1.4 (−2.0 to − 0.8) 0.258 0.026
  1. SMD is calculated as the change in the intervention school relative to the control school as a proportion of the standard deviation of the change. Analyses were conducted using GLM-ANOVA corrected for age, gender, age*gender ± SIMD with repeated measures for the outcome. Sedentary time and MVPA were also corrected for accelerometer wear time
  2. 95% CI 95% confidence interval, MVPA moderate to vigorous intensity physical activity, SIMD Scottish Index of Multiple Deprivation, SMD standardised mean difference
