Example
- Definition
- Harmonized (any 3 of 5)
- Sex
- Male
- Waist cut-point standard
- US / ATP III (M ≥102, F ≥88 cm)
- Waist circumference
- 104 cm
- Triglycerides
- 160 mg/dL
- On treatment for high triglycerides
- No
- HDL cholesterol
- 45 mg/dL
- On treatment for low HDL
- No
- Systolic BP
- 128 mmHg
- Diastolic BP
- 82 mmHg
The other 3 values
- On antihypertensive treatment
- No
- Fasting glucose
- 105 mg/dL
- On treatment for elevated glucose
- No
Result: Metabolic syndrome PRESENT (Harmonized: 3 of 5 criteria met). Met: waist >= 102 cm, TG >= 150 mg/dL, glucose >= 100 mg/dL.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Harmonized
- Present when any 3 of the 5 criteria are met (waist not mandatory).
- IDF
- Present when central obesity is met plus any 2 of the other 4.
