Objectives: To investigate the prevalence of ATPIII- and IDF-defined metabolic syndrome (MetS) in an Irish screening population and to determine the calculated cardiovascular risk for each group.
Design: A total of 1,716 subjects were enrolled over a 12-month period.
Main outcomes: The ATPIII-defined prevalence of MetS in this population was 13.2%. Using IDF criteria, 21.4% of subjects were identified as having the MetS. Correlation between the two definitions was high; however, IDF criteria identified an additional 9.5% (n = 164) of the population as having MetS, which ATPIII criteria failed to recognise.
Conclusion: We noted a higher prevalence of MetS in the studied population when defined by IDF criteria. However, those identified by IDF and not by ATPIII definition did not have a higher cardiovascular risk score by either Framingham or European Score than those without MetS. Thus, application of the ATPIII definition of MetS, may be the more practical.
