*Five parameters were used for diagnosing a patient with metabolic syndrome: waist circumference of ≥85 cm in men and ≥90 cm in women; triglyceride levels of ≥1.7 mmol/L (150 mg/dL) or specific treatment for this lipid abnormality; high-density lipoprotein cholesterol levels of <1.03 mmol/L (40 mg/dL) in men and <1.29 mmol/L (50 mg/dL) in women or specific treatment for this lipid abnormality; systolic blood pressure of ≥130 mm Hg, diastolic blood pressure of ≥85 mm Hg or treatment of previously diagnosed hypertension and fasting plasma glucose levels of >5.6 mmol/L (100 mg/dL) or previously diagnosed type 2 diabetes in accordance with the definition of the metabolic syndrome in International Diabetes Federation.
