Prevalence of the metabolic syndrome

As is the case for the diagnosis of diabetes, the application of different diagnostic criteria for the metabolic syndrome results in differing figures of prevalence and the identification of different individuals. It is still too early to see how the new IDF definition of the metabolic syndrome will fare, but application of the NCEP/ATPIII and WHO diagnostic criteria to individuals aged > 20 years in the National Health and Nutritional Examination Survey (NHANES) cohort resulted in an age-adjusted prevalence of 23.9% and 25.1%, respectively. Particular differences were noted in the prevalence for certain subgroups, such as African-American males, in whom the WHO estimates were higher (Ford and Giles, 2003). An earlier study by the same authors, using the NCEP/ATPIII criteria, had estimated similar overall prevalence figures (though as high as 43.5% in the 60-69-year age group), and suggested that this translated to 47 million US residents using the 2000 census data (Ford etal., 2002). It is also anticipated that the prevalence will continue to increase; in a recent publication from the US Centers for Disease Control and Prevention, the prevalence of the metabolic syndrome was compared between 1988-1994 and 1999-2000 using the NCEP definition. The age-adjusted prevalence was 24.1% in 19881994 and 27.0% in 1999-2000. The most striking figure was of a 23.5% increase in the prevalence in females across this time-frame, largely explained by increases in blood pressure, waist to hip ratio and hypertriglyceridaemia (Ford etal., 2004).
