title: The relevance of the metabolic syndrome.
abstract: BACKGROUND
  To review the definitions of the metabolic syndrome according to various expert groups and assess their relevance to clinical practice.
  
  
  METHODS
  Medline searches were conducted to identify studies which addressed: (i) the utility of the metabolic syndrome compared to multivariable predictive functions for the identification of individuals at high risk of type 2 diabetes mellitus (T2DM) and cardiovascular disease (CVD), (ii) the importance and definition of obesity in the definition of the metabolic syndrome and (iii) the impact of lifestyle and pharmacological interventions designed to reduce the risk of cardiovascular disease in those with and without the metabolic syndrome.
  
  
  RESULTS
  Although inferior to multivariable risk scores in predicting T2DM and CVD, the metabolic syndrome represents a simple clinical tool, particularly for the prediction of T2DM. Obesity is not a critical component of the metabolic syndrome for identifying those at increased risk of CVD but may be important for predicting T2DM. If anything, pharmacological therapy, especially lipid lowering is as, if not more, effective in those with the metabolic syndrome than in those without.
  
  
  CONCLUSIONS
  Although the metabolic syndrome appears to have limited utility for the identification of individuals at increased risk of T2DM or CVD, the diagnosis of the metabolic syndrome presents an opportunity to rationalise health services to deliver coordinated care to those with metabolic syndrome.
