Abstract:

Objective   To investigate the relationship between anthropometric parameters and glucose metabolism disorder risk of the adults in Shandong province. Methods   3011 residents aged over 20 years from 4 cities in Shandong province were investigated by cross-sectional and cluster sampling methods. The predictive values on glucose metabolism disorder risk of body mass index (BMI), waist circumference (WC), waist-to-hip ratio (WHR), and waist-to-height ratio (WHtR) were assessed by receiver operating characteristic curve (ROC) analysis and calculating the area under the ROC (AUC). Data of the subjects were analyzed by sex. Results   ① The optimal cutoffs to predict glucose metabolism disorder risk were found: BMI 24.95 for men and 24.25 for women, WC 91.5cm for men and 84.5cm for women, WHR 0.905 for men and 0.855 for women, and WHtR 0.535 for men and 0.525 for women. ② WHtR was found to have the largest areas under the ROC curve, respectively 0.627 for males and 0.693 for females. Conclusion   WHtR is the best predictive indicator for the glucose metabolism disorder risk. The optimal cutoffs of WHtR to predict glucose metabolism disorder risk were found: 0.535 for men and 0.525 for women.
