Objective:This study aims to evaluate the clinical value of the anthropometric waist-to-height ratio(WHtR) through the hyperinsulinemic-euglycemic clamp. Methods:A total of 154 subjects was included in the study. Lipid profiles and other biochemical markers were measured from the fasting blood sample. All the patients underwent hyperinsulinemic-euglycemic clamp,and the glucose metabolic rate,body mass index(BMI),waist circumference(WC),waist-to-hip ratio(WHR),WHtR and HOMA index were calculated. The ability of each index to predict the assessment of insulin resistance was compared. Results:Correlation analysis showed that WHtR(r=-0.730,P < 0.001),WHR(r=-0.651,P < 0.001),BMI(r=-0.717,P < 0.001),WC(r=-0.716,P < 0.001)were all significantly correlated with the glucose metabolic rate obtained in the hyperinsulinemic-euglycemic clamp. The area under ROC curve was HOMA-IR(0.860)> WHtR(0.850)> BMI(0.846)> WC(0.837)> WHt(0.749). The best value of WHtR for the diagnosis of insulin resistance was 0.56,which showed the highest sensitivity(93.9%)and specificity(66.7%)in the ROC curve. Conclusion:WHtR has a significant correlation with the glucose metabolic rate obtained from the hyperinsulinemic-euglycemic clamp,and has a higher sensitivity and specificity than BMI,WC and WHR,suggesting that it could be widely used in epidemiological studies or some large-scale clinical trials.
