About the Waist-to-Hip Ratio Calculator

Waist-to-Hip Ratio is treated here as a quantitative relation between Sex, Waist Circumference and Hip Circumference and Waist-to-Hip Ratio, Health Risk and Body Shape.

The calculator uses a multi formula configuration. Each reported value is read as a direct evaluation of the stored rules with the declared field formats and units.

Formula basis:
WHR = Waist Circumference / Hip Circumference
Men: Low < 0.90, Moderate 0.90 - 0.95, High > 0.95
Women: Low < 0.80, Moderate 0.80 - 0.85, High > 0.85

Interpret the outputs in the order shown by the result fields. Optional inputs affect only the outputs that depend on those variables.

Formula & How It Works

The calculation applies the following relations exactly as recorded in the metadata:

WHR = Waist Circumference / Hip Circumference
Men: Low < 0.90, Moderate 0.90 - 0.95, High > 0.95
Women: Low < 0.80, Moderate 0.80 - 0.85, High > 0.85

Each output field is produced by substituting the supplied inputs into the relevant relation and then applying the declared rounding or text format.

Worked Examples

Example 1: Low-Risk Male

Inputs

sex: male waist_cm: 84 hip_cm: 98
Waist-to-Hip Ratio: 0.86. Health Risk: Low. Body Shape: Pear (Gynoid)

With Sex = male, Waist Circumference = 84 and Hip Circumference = 98 as the stated inputs, the result is Waist-to-Hip Ratio = 0.86, Health Risk = Low and Body Shape = Pear (Gynoid). Each value corresponds to the declared output fields.

Example 2: High-Risk Male (Apple Shape)

Inputs

sex: male waist_cm: 102 hip_cm: 98
Waist-to-Hip Ratio: 1.04. Health Risk: High. Body Shape: Apple (Android)

With Sex = male, Waist Circumference = 102 and Hip Circumference = 98 as the stated inputs, the result is Waist-to-Hip Ratio = 1.04, Health Risk = High and Body Shape = Apple (Android). Each value corresponds to the declared output fields.

Example 3: Low-Risk Female

Inputs

sex: female waist_cm: 68 hip_cm: 95
Waist-to-Hip Ratio: 0.72. Health Risk: Low. Body Shape: Pear (Gynoid)

With Sex = female, Waist Circumference = 68 and Hip Circumference = 95 as the stated inputs, the result is Waist-to-Hip Ratio = 0.72, Health Risk = Low and Body Shape = Pear (Gynoid). Each value corresponds to the declared output fields.

Example 4: High-Risk Female (Post-Menopausal Pattern)

Inputs

sex: female waist_cm: 92 hip_cm: 100
Waist-to-Hip Ratio: 0.92. Health Risk: High. Body Shape: Apple (Android)

With Sex = female, Waist Circumference = 92 and Hip Circumference = 100 as the stated inputs, the result is Waist-to-Hip Ratio = 0.92, Health Risk = High and Body Shape = Apple (Android). Each value corresponds to the declared output fields.

Common Use Cases

  • Assess cardiovascular and metabolic disease risk
  • Determine apple vs pear body shape
  • Track abdominal fat changes over time
