Table 1. Important Definitions of Metabolic Syndrome in Adults.
| IDF | ATP III | EGIR | WHO | |
|---|---|---|---|---|
| Definitions | Abdominal obesity + two or more of these components | Presence of three or more of these components | Elevated plasma insulin (> 75th percentile) plus two other factors from among the following: | Glucose intolerance, impaired glucose tolerance (IGT) or diabetes mellitus (DM), and/or insulin resistance, together with two or more of the components listed below: |
| BMI, kg/m 2 | BMI is > 30 | -- | Body mass index (BMI) > 30 | |
| WHR or WC, cm | Dependent to population If BMI is > 30kg/m², central obesity can be assumed and waist circumference does not need to be measured | Dependent to population | Waist circumference (WC) ≥ 94 cm in men and ≥ 80 cm in women | Waist/hip ratio (WHR) > 0.9 in men and > 0.85 in women |
| TG, mg/dL | ≥ 150 (1.7 mmol/L) or specific treatment for this lipid abnormality | > 150 or drug treatment for elevated triglycerides | ≥ 150 | ≥ 150 |
| HDL, mg/dL | < 40 (1.03 mmol/L) in males < 50 (1.29 mmol/L) in females or specific treatment for this lipid abnormality | Men: < 40 Women: < 50 | < 39 for both men and women | < 35 in men and < 39 in women |
| BP, mm Hg | Systolic BP ≥ 130 or diastolic BP ≥ 85 or treatment of previously diagnosed hypertension | > 130/85 or drug treatment for elevated blood pressure | ≥ 140/90 or on antihypertensive treatment | ≥ 140/90 |
| FBG, mg/dL | (FPG) ≥ 100 (5.6 mmol/L), or previously diagnosed type 2 diabetes If above 5.6 mmol/L or 100, OGTT is strongly recommended but is not necessary to define presence of the syndrome | > 100 or drug treatment for elevated glucose | Impaired fasting glucose (IFG) or IGT, but no diabetes | |
| Albuminuria, µg/min | - | - | Urinary albumin excretion rate ≥ 20 μg/minute or albumin/creatinine ratio ≥ 30 μg/mg. |
