Anthropometric measures at baseline, follow-up, and change scores (mean ± SD or median [25th, 75th percentile]), among children participating in ANDALE Pittsburgh by weight status [overall (n = 49), and in children with body mass index percentile <85th (n = 26) or ≥ 85th (n = 23)]

^aOne child’s BMI was too high to calculate a z-score or percentile at baseline or follow-up;

p-values <0.05 were bolded to indicate statistical significance
