Background: Published studies seldom tested the weight of different waist circumference (WC) cut-off values for the diagnosis of metabolic syndrome (MetS) in predicting clinical outcomes, including cardiovascular disease and diabetes. Methods: This is a Chinese population-based cross-sectional study screening subjects from a Health Examination Program since 1999 to 2015. The MetS identification and scores were determined either according to the Adult Treatment Panel III/American Heart Association/National Heart, Lung, and Blood Institute (ATP III/AHA/NHLBI)- or Asian-WC cut-off points. The developments of a higher brachial-ankle pulse wave velocity (baPWV), defined as >= 1400 cm/s, and diabetic-level hyperglycemia, defined as a high fasting glucose level >= 6.99 mmol/L or postprandial glucose level >= 11.10 mmol/L, were surveyed by comparing the areas under receiver operating characteristic curves (AUC-ROC) for both MetS scores. Results: According to the ATP III/AHA/NHLBI- vs Asian-MetS criteria, 6633 vs 9133 (24.8% vs 34.2%, p < 0.001) subjects were diagnosed as the MetS among 26,735 study subjects with a mean age of 55 +/- 12 years. The stepwise increases in baPWV and prevalence of diabetic-level hyperglycemia were associated with both MetS scores after adjusting for age and sex. Both MetS scores yielded similar results for correlation with a higher baPWV (AUC-ROC = 0.685 for ATP III/AHA/HLBI- vs 0.680 for Asian-MetS, p = 0.271) and diabetic-level hyperglycemia (AUC-ROC = 0.791 for ATP III/AHA/HLBI- vs 0.784 for Asian-MetS, p = 0.546). Conclusions: In a stepwise manner, both ATP III/AHA/NHLBI- or Asian-MetS scores were strong risk factors for arterial stiffness and diabetes. Through a novel and holistic approach, the performance of the ATP III/AHA/ NHLBI-MetS score for the risks of arterial stiffness and diabetes was comparable to the Asian-MetS score among a Chinese population.
