- Abdominal obesity — defined as a waist circumference of 40 inches (102 centimeters) or above for men and 35 inches (89 centimeters) or above for women).
- A triglyceride level equal to or greater than 150 mg/dL (3.9 mmol/L).
- An HDL cholesterol level below 40 mg/dL (1.0 mmol/L) for men and below 50 mg/dL (1.3 mmol/L) for women.
- A blood pressure equal to or greater than 130/85 mmHg or the use of medication for hypertension.
- A fasting blood glucose level equal to or greater than 100 mg/dL (5.6 mmol/L) or the use of medication for hyperglycemia.
Measuring the circumference of your waist to detect abdominal obesity, meaning more fat is at your waist than at your hips, is a good start in assessing whether you may have metabolic syndrome. This is important because abdominal obesity represents a higher risk for heart disease and type 2 diabetes, and the risk increases progressively as waist size increases beyond the dimensions noted above. The implications of these factors are shown in the chart below.
