International Diabetes Federation Definition of the Metabolic Syndrome 2
| Central obesity |
| Waist circumference:a ethnicity‐specific values (eg, Europid: ≥94 cm for men, ≥80 cm for women; South Asian: ≥90 cm for men, ≥80 cm for women) |
| Refer also to Wahrenberg et al, 2005 3 |
| Plus any two of the following: |
| Raised triglyceride level |
| >150 mg/dL (1.7 mmol/L) OR treatment for this lipid abnormality |
| Reduced high‐density lipoprotein cholesterol level |
| <40 mg/dL (<1.03 mmol/L) in men /<50 mg/dL (<1.29 mmol/L) in women OR specific treatment for this lipid abnormality |
| Raised blood pressure |
| Systolic >130 mm Hg/diastolic >85 mm Hg OR treatment of previously diagnosed hypertension |
| Raised fasting plasma glucose levelb |
| Fasting plasma glucose level >100 mg/dL (>5.6 mmol/L) OR previously diagnosed type 2 diabetes |
| If >5.6 mmol/L or >100 mg/dL, oral glucose tolerance test is strongly recommended but is not necessary to define presence of syndrome |
| aIf body mass index is >30 kg/m2, central obesity can be assumed and waist circumference need not be measured. bIn clinical practice, impaired glucose tolerance is also acceptable, but all reports of prevalence of metabolic syndrome should use only fasting plasma glucose and presence of previously diagnosed diabetes to define hyperglycemia. Prevalence incorporating 2‐hour glucose results can also be added as supplementary findings. Reproduced with permission from Alberti et al, 2005. 2 |
