1. What is the Khamis Roche Height Equation?

The Khamis Roche method is a height prediction formula that estimates a child's adult height based on current age, weight, and mid-parental height. It's particularly useful for pediatric growth assessment and monitoring.

2. How Does the Calculator Work?

The calculator uses the Khamis Roche equation:

Where:

• \( age \) — Current age in years
• \( mid\_parental \) — Mid parental height in centimeters
• \( weight \) — Current weight in kilograms

Explanation: The equation combines genetic potential (mid-parental height) with current growth parameters to predict adult height.

3. Importance of Height Prediction

Details: Height prediction helps in assessing growth patterns, identifying potential growth disorders, and providing reassurance about normal development. It's particularly valuable in pediatric endocrinology.

4. Using the Calculator

Tips: Enter age in years, mid-parental height in centimeters, and current weight in kilograms. All values must be positive numbers for accurate calculation.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Khamis Roche method?
A: The method has about 90% accuracy within ±2 inches for children between ages 4-17 years when proper measurements are taken.

Q2: What is mid-parental height?
A: Mid-parental height is the average of the biological parents' heights, calculated as (father's height + mother's height) / 2.

Q3: At what age is this prediction most accurate?
A: The prediction is most reliable between ages 8-16 years when growth patterns are more established but before final height is reached.

Q4: Are there limitations to this method?
A: The method may be less accurate for children with growth disorders, nutritional deficiencies, or those who experience early or late puberty.

Q5: Can this predict height for all ethnicities?
A: While developed for general use, the equation may have variations in accuracy across different ethnic populations and should be interpreted with clinical context.
