Metabolic Syndrome Calculator — NCEP ATP III Criteria
Enter five clinical measurements — waist circumference, triglycerides, HDL cholesterol, blood pressure, and fasting glucose — to check how many NCEP ATP III metabolic syndrome criteria are met. Three or more is consistent with metabolic syndrome.

Reduced HDL cholesterol

Elevated blood pressure

Elevated fasting glucose
105 mg/dL ≥ 100 = 1 - 6

0 + 1 + 1 + 0 + 1 = 33 or more criteria = metabolic syndrome.
How does this calculator work?
Metabolic syndrome = 3 or more of 5 criteria (NCEP ATP III): waist > 102/88 cm (M/F), triglycerides ≥ 150 mg/dL, HDL < 40/50 mg/dL (M/F), blood pressure ≥ 130/85 mmHg or on BP meds, fasting glucose ≥ 100 mg/dL. It signals elevated cardiovascular and type 2 diabetes risk — lifestyle changes can reverse it.
Formula
How this is calculated
Metabolic syndrome is a cluster of cardiometabolic risk factors that together raise the risk of type 2 diabetes and cardiovascular disease. The NCEP ATP III definition (2001, harmonized 2009) uses five binary criteria, each compared to a fixed threshold: abdominal obesity (waist > 102 cm in men, > 88 cm in women); elevated triglycerides (≥ 150 mg/dL); reduced HDL cholesterol (< 40 mg/dL in men, < 50 mg/dL in women); elevated blood pressure (systolic ≥ 130 or diastolic ≥ 85 mmHg, or currently on antihypertensive medication); and elevated fasting blood glucose (≥ 100 mg/dL). Confirming three or more makes the diagnosis.
The original ATP III thresholds are based on population studies and reflect absolute cut-offs rather than percentiles — they apply to adults and are less well-validated in children or during pregnancy. The 2009 Joint Harmonized Criteria (IDF/AHA/WHAF) use the same five components but allow for ethnic-specific waist-circumference thresholds (for example, lower cut-offs for Asian populations at 90/80 cm); this calculator uses the original ATP III waist thresholds (102/88 cm).
Metabolic syndrome can often be reversed with lifestyle changes: sustained weight loss, increased physical activity, and a diet lower in refined carbohydrates and saturated fat reduce all five risk factors simultaneously. A positive screening result from this tool warrants discussion with a physician about confirmatory testing and management options.
Frequently asked questions
Three or more of the five NCEP ATP III criteria must be met: abdominal obesity, elevated triglycerides, reduced HDL cholesterol, elevated blood pressure, and elevated fasting glucose.
No. It applies the published NCEP ATP III thresholds for educational screening only. A physician or qualified clinician should confirm any diagnosis and recommend treatment.
No. The 2009 Joint Harmonized Criteria allow ethnic-specific thresholds — Asian populations often use lower cut-offs (90 cm men, 80 cm women). This calculator uses the original NCEP ATP III values (102/88 cm) most widely cited in North American and European guidelines.
