1. What is Waist-to-Height Ratio?

The Waist-to-Height Ratio (WHtR) is a simple anthropometric measure of body fat distribution. It compares waist circumference to height and is a better predictor of cardiovascular risk than BMI alone.

2. How Does the Calculator Work?

The calculator uses the WHtR formula:

Where:

• \( Waist\ Circumference \) — Measured at the narrowest point between ribs and hips (cm)
• \( Height \) — Measured without shoes (cm)

Interpretation:

• WHtR < 0.5 — Healthy weight range
• WHtR 0.5-0.6 — Increased risk of health problems
• WHtR > 0.6 — High risk of health problems

3. Importance of WHtR

Details: WHtR is a better indicator of central obesity and health risks than BMI alone. It correlates strongly with visceral fat and metabolic syndrome risk factors.

4. Using the Calculator

Tips: Measure waist circumference at the narrowest point between ribs and hips while standing. Height should be measured without shoes. Both measurements should be in centimeters.

5. Frequently Asked Questions (FAQ)

Q1: Why use WHtR instead of BMI?
A: WHtR better accounts for body fat distribution and is more sensitive to central obesity, which carries higher health risks.

Q2: Is WHtR different for men and women?
A: The 0.5 cutoff applies to both genders, though some studies suggest slightly different cutoffs (0.53 for men, 0.49 for women).

Q3: How should I measure my waist?
A: Stand and measure at the narrowest point between ribs and hips, or midway between these points if no obvious narrowing.

Q4: Does WHtR apply to children?
A: Yes, but interpretation differs by age. Generally, WHtR > 0.5 indicates increased risk in children.

Q5: What's better - WHtR or waist circumference?
A: WHtR is generally better as it accounts for height differences between individuals.
