1. What is Waist-to-Height Ratio?

WHtR (Waist-to-Height Ratio) is a simple measure of central obesity that compares waist circumference to height. It's particularly useful as a complement to BMI for assessing health risks associated with abdominal fat.

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)

Explanation: The ratio indicates how much abdominal fat a person has relative to their height.

3. Importance of WHtR Calculation

Details: WHtR is a better predictor of cardiovascular risk than BMI alone. A ratio above 0.5 indicates increased health risks, regardless of BMI.

4. Using the Calculator

Tips: Measure waist at the narrowest point (typically just above the belly button). Stand straight against a wall for height measurement. Enter values in centimeters.

5. Frequently Asked Questions (FAQ)

Q1: What is a healthy WHtR for women?
A: For women, a WHtR below 0.5 is considered healthy. Above 0.5 indicates increased health risks.

Q2: How does WHtR differ from BMI?
A: WHtR specifically measures abdominal obesity, while BMI is a general weight-to-height ratio. WHtR better predicts metabolic risks.

Q3: When should I measure my waist?
A: Measure in the morning before eating, at the end of a normal breath. Avoid measuring after large meals.

Q4: Are there limitations to WHtR?
A: WHtR may be less accurate for very tall or short individuals, and doesn't account for muscle mass.

Q5: Should children use WHtR?
A: Yes, WHtR is particularly useful for children as it doesn't require age-adjusted percentiles like BMI.
