How this calculator works
Any three of the five findings meet the specified definition. Each counts once, including when the criterion is met by qualifying treatment. This page deliberately identifies its guideline version: population-specific waist thresholds and other definitions can classify people differently. The result is an estimate for information only and is not medical advice.
Formula
Count = waist criterion + triglyceride criterion + HDL criterion + blood pressure criterion + fasting glucose criterion. The AHA/NHLBI 2005 definition requires at least 3 of 5.
Worked example
A qualifying waist measurement, high triglycerides and hypertension treatment count as three criteria even if the treated blood pressure is below the numerical threshold. High triglycerides and low HDL alone count as two.

Frequently asked questions
Must both blood pressure numbers be high?
No. Systolic pressure at least 130 or diastolic pressure at least 85 meets that component. Qualifying treatment also counts.
Are all lipid medicines enough to select Yes?
No. The treatment alternative refers to treatment for that particular abnormality, such as reduced HDL or elevated triglycerides. Do not infer it from any lipid prescription.
Are these waist thresholds appropriate for every population?
No. This page uses the specified 2005 general thresholds. Different population-specific thresholds may be clinically appropriate, including lower thresholds for some Asian populations.
