As defined by IDF Criteria:

• Elevated Waist Circumference (WC): For subjects 16 years and older, WC ≥ 94cm for males and ≥ 80 cm for females. For ages 13–15 years, WC ≥ 90th percentiles or adult cut-off value if lower;

• Low HDL: For subjects 16 years and older HDL < 40 mg/dL for males and < 50 mg/dL for females. For ages 13–15 years, HDL < 40 mg/dL;

• High TG: TG ≥ 150 mg/dL;

• Hypertension: SBP ≥ 130 mmHg or DBP ≥ 85 mmHg; and

• High Fasting Glucose: ≥ 100 mg/dL.
