increased morbidity risk related to central obesity was discussed in various studies (Yoo, 2016). Our findings support to
its robustness.
WHtR in present study appeared as a more predictive indicator than WC, which is consistent with the previous studies
that found that WHtR is superior to BMI in predicting cardiometabolic risk (Šimundić, 2009; Yoo, 2016). In a similar
