Abstract
Objective To study the correlation between body mass index (BMI),waist circumference(WC),waist-hip ratio(WHR),percent body fat (%BF) and insulin resistance(IR) in primary and middle school students. Methods Height,weight,waist circumference,hip circumference,%BF,the fasting blood glucose (FBG) and fasting insulin (FIN) of 247 cases of schoolchildren were measured,and BMI and WHR were calculated.HOMA-IR index was calculated and receiver operating characteristic (ROC) analysis was used to find the optimal cutoff of HOMA-IR for the indicators. Results The area under the ROC curve and the optimal cutoff for BMI were 0.771,27.45,and for waist-to-hip ratio 0.681,0.923,and for waist circumference,0.777 cm,86.5 cm,and for fat rate were 0.66%,26.85%,respectively. Conclusions Waist circumference,BMI,waist hip ratio,%BF can be used as a reference index to predict the IR.Waist circumference and BMI is the best prediction index of IR.
