1. What is the Deurenberg Equation?

The Deurenberg equation estimates body fat percentage from BMI and age specifically for women. It provides a simple method to assess body composition without requiring specialized equipment.

2. How Does the Calculator Work?

The calculator uses the Deurenberg equation for women:

Where:

• \( BMI \) — Body Mass Index (kg/m²)
• \( Age \) — Age in years

Explanation: The equation accounts for the relationship between BMI, age, and body fat percentage in women.

3. Importance of Body Fat Percentage

Details: Body fat percentage is a key indicator of health and fitness. It provides more meaningful information than weight alone, helping to assess risks for various health conditions.

4. Using the Calculator

Tips: Enter your BMI in kg/m² and age in years. Both values must be valid (BMI > 0, age between 1-120).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this equation?
A: The equation provides a reasonable estimate but may not be accurate for all individuals, especially athletes or those with unusual body compositions.

Q2: What are healthy body fat percentages for women?
A: Generally, 21-33% is considered healthy for women aged 20-40, with slightly higher ranges for older women.

Q3: How should BMI be calculated?
A: BMI = weight (kg) / (height (m))². Alternatively: (weight (lbs) / (height (in))²) × 703.

Q4: Are there limitations to this equation?
A: Less accurate for very muscular individuals, pregnant women, and those at extremes of age or BMI.

Q5: Should this be used for medical diagnosis?
A: For precise body composition analysis, more advanced methods like DEXA scans or hydrostatic weighing are recommended.
