Abdominal Perimeter

Definition

Measure of the circumference of the abdomen at the level of the navel. It is an indicator of abdominal fat tissue and metabolic risk, particularly for cardiovascular diseases and diabetes.

How it works

Abdominal perimeter is measured at mid-distance between the last rib and the iliac crest, with the patient standing and the abdomen relaxed. This measure specifically evaluates visceral fat, which is metabolically more active and more associated with health risks than subcutaneous fat. An increased waistline is an independent risk factor for metabolic syndrome, hypertension, diabetes, and cardiovascular diseases. Risk thresholds differ by sex and ethnicity.

Role

Indicator of abdominal fat tissue and metabolic and cardiovascular risk.

Examples

• Evaluation of the metabolic syndrome. Cardiovascular risk screening. Abdominal obesity follow-up. Evaluation of weight loss program effectiveness.

Recommendations

Measure abdominal perimeter during annual health checks. A target abdominal perimeter is less than 94 cm for men and 80 cm for women according to the WHO to reduce metabolic risks.

Key takeaway

Abdominal perimeter is an important predictor of metabolic and cardiovascular risk, more relevant than BMI alone.
