| Criteria/components | Age | ||
|---|---|---|---|
| 6 to < 10 years-old | 10 to 16 years-old | > 16 years-old | |
| Adiposity definition | WC ≥ 90th percentile | WC ≥ 90th percentile | WC ≥ 90 cm (boys) or ≥ 80 cm (girls) |
| Glucose metabolism | Without cut-off definition for MS diagnosis | Fasting blood glucose ≥ 100 mg/dl | Fasting blood glucose ≥ 100 mg/dl |
| Dyslipidemia | Without cut-off definition for MS diagnosis | Tg ≥ 150 mg/dl or HDL-ch ≥ 40 mg/dl or taking LLD | Tg ≥ 150 mg/dl or HDL-ch ≥ 40 (boys) or ≥ 50 mg/dl (girls) or taking LLD |
| Arterial hypertension | Without cut-off definition for MS diagnosis | DBP ≥ 130 or SBP ≥ 85 mmHg or taking AHD | DBP ≥ 130 or SBP ≥ 85 mmHg or taking AHD |
WC: waist circumference; MS: metabolic syndrome; Tg: triglyceride levels; HDL-ch: HDL-cholesterol levels; LLD: lipid-lowering drug; DBP: diastolic blood pressure; SBP: systolic blood pressure; AHD: antihypertensive drug.
