2009]. According to the above, the

diagnosis of MetS should be established if any three of the five criteria described below are present: Table 1. Criteria for the metabolic syndrome definition (adapted from Cornier et al. 2008, International Diabetes Federation, 2006). Elevated waist circumference, according to population- and country-specific definitions (usually high thresholds for North America and North Europe, moderate thresholds for Asia, the Middle East, the Mediterranean, Africa, Central and South America and low thresholds for China and Japan). Elevated triglycerides (≥150 mg/dl) or drug treatment for dyslipidaemia. Reduced high-density lipoprotein Inhibitors,research,lifescience,medical (HDL) (<40 Inhibitors,research,lifescience,medical mg/dl) or drug treatment for hypercholesterolaemia. Elevated blood pressure (systolic ≥130 mmHg, diastolic ≥85 mmHg) or a history of hypertension or drug treatment for hypertension. Elevated fasting glucose (≥100 mg/dl) or drug treatment for hyperglycaemia. The

prevalence of MetS is increasing throughout the world but is partly dependent on the definition that is used to determine inclusion as well as the composition Inhibitors,research,lifescience,medical of the population being studied (i.e. sex, age, race and ethnicity) [Cornier et al. 2008]. Using the modified NCEP-ATP III criteria, the National Health and Nutrition Examination Survey (NHANES) compared data from a US cohort of 6423 adults (1988–1994) with a www.selleckchem.com/products/Carboplatin.html similar one of 6962 participants (1999–2006) and concluded that there has been an increase in age-adjusted MetS prevalence from 29.2% to 34.2% Inhibitors,research,lifescience,medical respectively over the years [Mozumdar and Liguori, 2011]. Efforts to control specific cardiovascular risk factors, such as blood pressure or total serum cholesterol levels, worldwide appear to have been partially effective since the 1980s (especially for countries with high income) [Danaei et al. 2011; Inhibitors,research,lifescience,medical Farzadfar et al. 2011]. Despite this, the mean body mass index (BMI) of the world’s

population has shown a constant increase in the last three decades, both in developed and developing countries [Finucane et al. 2011]. Although 17-DMAG (Alvespimycin) HCl this increase in BMI is likely to be a positive thing in developing countries, as it indicates that more people have better nutrition, in developed countries this is giving rise to the so-called ‘obesity epidemic’. So it appears that MetS is common and increasing in the general population regardless of definition. Increased calorie intake and sedentary lifestyles have been implicated in the development of MetS worldwide, and without doubt constitutes a major public health risk. However, it is worth noting that certain population groups and more importantly certain patient groups have an even greater predisposition to developing MetS.
