Frequently asked questions
What waist size is healthy for women?
Under 80 cm is below the common cut-offs. 88 cm and above is the substantially increased band.
What waist size is healthy for men?
Under 94 cm is below the cut-offs. 102 cm and above is substantially increased risk.
Navel or natural waist?
WHO measures midway between the rib and the iliac crest, not necessarily across the navel.
Can waist shrink without weight loss?
Waist can fall as abdominal fat or bloating decreases even if the scale is unchanged. Measure at the same time and conditions.
