AUC area under the receiver operating characteristic curve, CI confidence interval, OR odds ratio, WC waist circumference, BMI body mass index, WHR waist-hip ratio, WHtR waist-height ratio, MaHtR mid-upper arm height ratio
^aOR was calculated by every increase of approximately one standard deviation of anthropometric measurements (1.5 for BMI z-score, 0.05 for WHR and WHtR, 0.02 for MHR)
^bAdjusted for age, energy intake, total physical activity, nutraceutical use, living area, and family income
