Notes: Triglycerides and HDL thresholds consider active lipid therapy. Blood pressure criterion considers antihypertensive therapy. Glucose criterion considers fasting value, HbA1c at selected threshold, known diabetes, or hypoglycemic agents.

Formulae and Thresholds Used
  • Definition: Any 3 or more of the five criteria below.
  • Waist circumference (central obesity):
    • NCEP ATP III: Men > 102 cm (40 in), Women > 88 cm (35 in).
    • IDF Europid: Men ≥ 94 cm (37.0 in), Women ≥ 80 cm (31.5 in).
    • IDF South/East Asian, Japanese, Chinese, Korean: Men ≥ 90 cm (35.4 in), Women ≥ 80 cm (31.5 in).
    • Custom: Enter male/female cutoffs in cm to override.
  • Triglycerides: ≥ 150 mg/dL (1.7 mmol/L) or on drug treatment.
  • HDL cholesterol: < 40 mg/dL (1.03 mmol/L) in men; < 50 mg/dL (1.29 mmol/L) in women; or on drug treatment.
  • Blood pressure: SBP ≥ 130 mmHg or DBP ≥ 85 mmHg; or on antihypertensive treatment.
  • Dysglycemia: Fasting glucose ≥ 100 mg/dL (5.6 mmol/L), or HbA1c ≥ selected threshold (5.7% or 6.5%), or known diabetes, or glucose-lowering therapy.
  • Useful derived ratios (informative only): TG/HDL and Waist/Height (target < 0.5).
  • Conversions: TG mmol/L = mg/dL / 88.57; HDL mmol/L = mg/dL / 38.67; Glucose mmol/L = mg/dL / 18; Inches = cm / 2.54.

Ethnicity presets approximate published guidance and can be changed via the Custom option. Clinical decisions require professional judgment.

1) Criteria Summary by Set
Criteria Set Male Waist Cutoff Female Waist Cutoff Other Components (apply to all sets)
ATP III 102 cm 88 cm TG ≥150, HDL low, BP ≥130/85, FPG ≥100 or therapy
IDF Europid 94 cm 80 cm TG ≥150, HDL low, BP ≥130/85, FPG ≥100 or therapy
IDF South Asian 90 cm 80 cm TG ≥150, HDL low, BP ≥130/85, FPG ≥100 or therapy
IDF East Asian / Japanese 90 cm 80 cm TG ≥150, HDL low, BP ≥130/85, FPG ≥100 or therapy
Custom As entered As entered TG ≥150, HDL low, BP ≥130/85, FPG ≥100 or therapy

HDL low = <40 mg/dL (men) or <50 mg/dL (women), or lipid therapy.

2) Interpretation Guide
Met Criteria Count Status Typical Next Steps
0–1 Unlikely Lifestyle reinforcement, routine follow-up
2 Borderline Risk discussion, repeat measurements, lifestyle focus
≥3 Meets Criteria Clinical evaluation, risk management, guideline-based care

3) Common Conversions
Analyte mg/dL → mmol/L mmol/L → mg/dL
Triglycerides Divide by 88.57 Multiply by 88.57
HDL cholesterol Divide by 38.67 Multiply by 38.67
Glucose (fasting) Divide by 18 Multiply by 18

Waist inches = cm ÷ 2.54. Height inches = cm ÷ 2.54.

4) Sample Scenarios
Scenario Inputs (key values) Count Interpretation
A Male, ATP III, Waist 104 cm, TG 210, HDL 38, BP 134/86, FPG 92 4 Meets metabolic syndrome criteria
B Female, IDF SA, Waist 82 cm, TG 140, HDL 55, BP 128/80, FPG 101 2 Borderline: two criteria present
C Male, Europid, Waist 90 cm, TG 130, HDL 52, BP 118/76, FPG 90 0 Metabolic syndrome unlikely
