How it works
WHtR = waist circumference ÷ height (same units, e.g., cm/cm).
Example
Waist 88 cm, height 180 cm WHtR ≈ 0.489.
Reference Table
| Value | Meaning |
|---|---|
| Near 0.5 | Common screening line in some guidelines |
| Trends | Rising WHtR may warrant lifestyle review |
| Kids | Use pediatric references, not adult shortcuts |
FAQ
Do I convert units?
Use the same unit top and bottom; the ratio is unitless.
After big meals?
Measure fasting or at a consistent time of day.
Visceral fat?
WHtR correlates with central adiposity but is not imaging.
Athletes?
Core muscle can influence waist; context matters.
