  1. BMI and fitness scores are standardized for age.
  2. "Lean" refers to children with age and sex specific BMI <10th percentile.
  3. 95% confidence intervals are indicated between brackets.
  4. * refers to statistically significant difference in comparison to children with "normal" weight (p < 0.05).
