Can we apply the National Cholesterol Education Program Adult Treatment Panel definition of the metabolic syndrome to Asians?
OBJECTIVE: Limited information is available about the metabolic syndrome in Asians. Furthermore, the definition of central obesity using waist circumference may not be appropriate for Asians. The objectives of this study were to determine the optimal waist circumference for diagnosing central obesity in Asians and to estimate the prevalence of the metabolic syndrome in an Asian population.
