The Diagnostic Criteria of Metabolic Syndrome and the Risk of Coronary Heart Disease according to Definitions in Men

Abstract

Methods: The participants were 426 men above forty years old who had visited to have health screening in a general hospital in Daegu from March to December in 2007. The diagnostic criteria of MS and Kappa statistic were calculated according to the following five diagnostic definitions; modified World Health Organization (WHO), National Cholesterol Education Program Third Adult Treatment Panel (NCEP-ATP III), International Diabetes Federation (IDF), American Heart Association/National Heart, Lung and Blood Institute (AHA/NHLBI) and NCEP-ATP III modified waist circumference ≥ 90 cm (modified NCEP-ATP III). The sensitivity and specificity of each definition of MS were calculated with respect to high risk group by Framingham risk score (FRS). Results: The diagnostic criteria of MS were 6.6% by IDF, 7.7% by WHO, 10.6% by NCEP-ATP III, 18.1% by modified NCEPATP III and 22.3% by AHA/NHLBI. The kappa satistic ranged from 0.30 to 0.87. The sensitivity of each definition with respect to FRS was 8.3% in IDF, 13.4% in WHO, 15.3% in NCEP-ATP III, 27.4% in modified NCEP-ATP III and 32.5% in AHA/NHLBI. Conclusion: There was great difference in the diagnostic criteria of MS according to diagnostic definitions. The author suggests that AHA/NHLBI or modified NCEP-ATP III definition may be better for screening high risk group of coronary heart disease than others.
