^aThe established obesity cut-off points are 30 kg/m² for BMI, 90 cm (men) and 80 cm (women) for WC, 0.5 for WHtR, 0.9 (men) and 0.85 (women) for WHR
^bAUCs for all obesity indices except BMI were significantly different from 0.50
^cAUC for BMI of men was significantly lower than WC and WHtR (p < 0.01) and WHR (p < 0.05)
