  1. 1 Cutoffs defined by CDC growth reference curves [20].
  2. 2 Based on the prevalence of BMI percentile-defined overweight and obesity in females and males in our dataset. Abbreviations are as follows: Sens sensitivity, Spec specificity, LR+ likelihood ratio positive, LR- likelihood ratio negative, AUC area under the receiver operating characteristic curve.
