AUC: area under curve; 95%CI: 95% confidence interval; CP: cut-off point; BMI: body mass index; NCEP-ATP III: National Cholesterol Education Program Adult Treat- ment Panel III; NC: neck circumference; WC: waist circumference; WHtR: waist-to-height ratio.

AUC values greater than 0.70 are indicated in bold.

* ^{† ‡} Hanley and McNeil test results are presented as symbols; there was no significant difference in AUC for body fat indicators marked with the same symbols (p>0.05).
