1. What is the Khamis Roche Height Calculator?

The Khamis Roche method is a mathematical model that predicts adult height based on a child's current height, weight, and mid-parental height. It's considered one of the most accurate methods for height prediction in children.

2. How Does the Calculator Work?

The calculator uses the Khamis Roche equation for boys:

\[ Adult Height = 40.746 + 0.783 \times Child Height + 0.147 \times Child Weight + 0.188 \times Mid Parent Height \]

Where:

Child Height — Current height of the child in centimeters
Child Weight — Current weight of the child in kilograms
Mid Parent Height — Average of biological parents' heights in centimeters

Explanation: The equation combines genetic factors (mid-parental height) with current growth measurements to predict final adult height.

3. Importance of Height Prediction

Details: Height prediction helps parents and healthcare providers monitor growth patterns, identify potential growth disorders, and set realistic expectations for a child's final height.

4. Using the Calculator

Tips: Enter accurate measurements in centimeters and kilograms. For mid-parental height, calculate the average of both biological parents' heights. The calculator is designed for boys aged 4-17 years.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is the Khamis Roche method?
A: The method is approximately 90% accurate within ±2 inches (5 cm) for children aged 4-17 years when proper measurements are taken.

Q2: What is mid-parental height?
A: Mid-parental height is the average of the biological mother's and father's heights. For boys: (Father's height + Mother's height + 13 cm) ÷ 2

Q3: At what age is height prediction most accurate?
A: Predictions become more accurate as children get older, with the best accuracy typically between ages 8-13.

Q4: Are there different equations for girls?
A: Yes, the Khamis Roche method has different coefficients for girls. This calculator uses the equation specifically for boys.

Q5: What factors can affect the accuracy of prediction?
A: Nutrition, health conditions, hormonal disorders, and timing of puberty can all influence the accuracy of height predictions.
