  1. The 4-year follow-up post-intervention measurements were conducted over the 2014 academic year in Reus (intervention group) and in Cambrils, Salou and Vila-seca (control group)
  2. Bold text indicates significant p-values
  3. aThe results are expressed as the means (95% CIs)
  4. bWeight, height, lean mass and hip circumference; values adjusted by age with an analysis of covariance (ANCOVA)
  5. cBody mass index (BMI) is calculated as weight (kg) divided by height in square meters
  6. dFat and lean mass are calculated by using a standard beam balance (Tanita TBF-300 Body Composition Analyzer)
  7. eBMI, BMI z-score and fat mass, waist circumference, not adjusted by age, are calculated by using an analysis of variance (ANOVA)
