Waist Circumference
Waist circumference is a simple tape measurement that estimates how much fat is stored around your organs — a key marker of health risk, even when BMI looks normal.
Plain English
Patient-Friendly Explanation
Waist circumference is a simple tape measurement around your waist that estimates how much fat is stored around your organs. Fat in this area — called central or abdominal fat — is more harmful to health than fat elsewhere. For most Asian adults, a waist of 90 cm or more for men, or 80 cm or more for women, signals increased health risk.
Medical
Clinical Definition
Waist circumference is a validated anthropometric index of abdominal (visceral) adiposity and an independent predictor of cardiometabolic risk beyond BMI. Per WHO protocol, it is measured midway between the lowest rib and the iliac crest at the end of normal expiration. For Asian populations, the WHO/IDF cut-offs for increased risk are ≥90 cm in men and ≥80 cm in women; these thresholds identify metabolically obese individuals who may have a normal BMI. Visceral adipose tissue drains into the portal circulation, promoting insulin resistance, dyslipidaemia and inflammation — the basis of the term "central obesity".
