[Comparison of 3 working definitions of metabolic syndrome in male medical examinees].
OBJECTIVE
To compare the prevalence of the metabolic syndrome (MS) using 3 working definitions proposed respectively by the World Health Organization (WHO, 1999) , the Third Report of the National Cholesterol Education Program Expert Panel on Detection, Evaluation, and Treatment of High Blood Cholesterol in Adults ( ATP III, 2001 ), and the Chinese Diabetes Society ( CDS, 2003).


METHODS
MS was diagnosed in 739 male medical examinees by the 3 working definitions respectively, then the prevalence and the concordance of 3 working definitions was compared.


RESULTS
Among 739 participants the prevalence was 36.9% by the WHO definition, 11.8% by the ATP III definition and 21.0% by the CDS definition. Among all the testees 68.6% were classified as either having or not having the MS under the 3 definitions. The consistency in the diagnosis of MS was 72.5% by the WHO definition and the ATP III definition, 81.2% by the WHO definition and the CDS definition, and 83.5% by the ATP III definition and the CDS definition. The prevalence of insulin resistance was the highest among the components of the WHO definition. The prevalence of hypertension was the highest while the prevalence of obesity was the lowest by the ATP III definition. Among the components of the CDS definition, the prevalence of obesity was the highest. The fasting insulin and insulin resistant index (HOMA-IR) were both significantly higher in the MS subjects than that in the non-MS subjects.


CONCLUSIONS
A universally accepted definition of the metabolic syndrome is needed.
