Predictive Value of Obesity Index to the Metabolic Syndrome among Tianjin Adults / 中国医科大学学报

ABSTRACT

Objective To explore the predictive value of obesity-related index for metabolic syndrome(MS)among Tianjin adults. Methods A total of 522 adults who participated in a physical examination were included in this cross-sectional study. Participants 'gender and age were record-ed,height,weight,waist circumference(WC)and hip circumference were measured,and TC,TG,HDL-C and FPG were tested. The receiver op-erating characteristic(ROC)curves were generated to identify the optimal measurement of obesity for the prediction of metabolic risk in this popu-lation. Results The area under the ROC curve(AUC)value for waist-to-height ratio(WHtR)predicted the maximum value of MS,followed by WC and BMI,and WHR was the lowest. The optimal cut off value of WHtR was 0.509. There was significant difference in the ability of BMI be-tween different age groups and WC to predict MS. In the groups of<40 years old and≥60 years old,BMI had higher predictive value for MS than WC. Conclusion WHtR has the best predictive value for evaluating the MS risk compared to BMI ,WC or WHR alone among Tianjin adults. The predictive value of BMI and WC for evaluating the MS risk can be improved by the method of age stratification.
