Correlation for WHtR and number of risk factors for metabolic syndrome (MetS) except for waist circumference. WHtR were 0.534 in a group that has no metabolic risk factor and 0.572 in a group that has 4 metabolic risk factors (except for waist circumference), respectively. WHtR increased with increasing number of risk factors for metabolic syndrome (Total: r=0.172, P value<0.001, Male: r=0.207, P value<0.001, Female: r=0.151, P value=0.001).
