* Defined as high insulin levels compared to the background population
| WHO (1999) | EGIR (1999) | NCEP/ATPlll(2001) | IDF (2005) | |
| Definition | High blood sugar or diabetes or insulin resistance and 2 of the other factors | Insulin resistance and 2 of the other factors | Any three or more of the following factors | Waistline fat and 2 other factors |
| Blood glucose/ insulin conditions | High glucose levels or diabetes or insulin resistance* | Fasting glucose ≥6.1mmol/L; insulin resistance * | Fasting glucose ≥110 mg/dL | Fasting glucose ≥5.6 mmol/L or previous diagnosis of impaired glucose tolerance or diabetes |
| Triglyceride levels | >150 mg/dL | >2 mmol/L | ≥150 mg/dL | ≥ 1.7 mmol/L |
| HDL levels | <35 mg/dL (men) <39 mg/dL (women) | < 1 mmol/L or on treatment | < 40 mg/dL (men)< 50 mg/dL (women) | <1.04 mmol/L (men) <1.29 mmol/L (women) |
| Blood Pressure | ≥140/ 90 | ≥140/ 90 or on treatment | ≥130/ ≥85 mmHg | ≥ 130 SBP or ≥ 85 DBP or on treatment |
| Waistline fat | Waist:hip ratio>0.9 (men)>0.85 (women)and/or body mass index >30 kg/m2 | Waist circumference>94 cm (men)>80 cm (women) | Waist circumference>102 cm (men)> 88 cm (women) | Waist circumference>94 cm (European men)>90 cm (Asian men)>80 cm (women) |
| Other criteria | Microalbuminuria: urinary albumin excretion ratio ≥ 20 mg/min or albumin:creatinine ratio ≥ 30 mg/g |
