In 2005, the International Diabetes Federation (IDF) released a consensus clinical definition of the metabolic syndrome for worldwide use that included central obesity as a prerequisite (1). The IDF definition varied from the earlier Third Report of the U.S. National Cholesterol Education Program Adult Treatment Panel (ATP III) panel definition with broader criteria for waist circumference, HDL, and fasting plasma glucose (2). The impact of these changes to the prevalence of the metabolic syndrome, in particular the use of differing values for defining central obesity, has not been studied. Our aim was to compare these two definitions for the distribution and prevalence of the metabolic syndrome in a representative biomedical population study of predominantly European adults from Adelaide, South Australia (population 1.2 million) (3).
