Correlations between indicators were determined using the Pearson correlation coefficient (r). Linear regression was carried out with PBF as a dependent variable to test the further association of potential indicators. - Results: The strongest correlation was found between PBF and WHtR in all pubertal stages (0.712
0.556
0.638 in male
0.635
0.799
0.611 in female, respectively). The regression analysis indicated that WHtR was the most effective estimator of PBF ( = 0.69
RMSE = 4.54 for male and = 0.50
RMSE = 4.34 for female) in the model including pubertal stage variable for each gender. - Conclusions: The results support the use of WHtR as an effective indicator for detecting adiposity in Vietnamese children and adolescents. DOI: 10.59715/pntjmp.1.4.14
