1. What is Mid-Parental Height Prediction?

Mid-parental height prediction is a method to estimate a child's adult height based on the heights of biological parents. It provides a rough estimate of genetic height potential.

2. How Does the Calculator Work?

The calculator uses the mid-parental height formula:

Where:

• \( Father \) — Father's height in centimeters
• \( Mother \) — Mother's height in centimeters
• \( Adjustment \) — Adjustment factor based on child's gender

Explanation: The adjustment factor accounts for gender differences in height potential. For boys, typically add 13 cm; for girls, subtract 13 cm.

3. Importance of Height Prediction

Details: Height prediction helps parents and healthcare providers monitor a child's growth pattern and identify potential growth disorders early.

4. Using the Calculator

Tips: Enter parent heights in centimeters. Use positive adjustment for boys (typically +13 cm) and negative adjustment for girls (typically -13 cm).

5. Frequently Asked Questions (FAQ)

Q1: How accurate is mid-parental height prediction?
A: It provides a rough estimate within ±5 cm for about 68% of children and within ±10 cm for about 95% of children.

Q2: What adjustment values should I use?
A: For boys: +13 cm; for girls: -13 cm. These values account for average height differences between genders.

Q3: At what age is this prediction most accurate?
A: This method provides the best prediction when children are between 2-8 years old.

Q4: What factors can affect the accuracy of prediction?
A: Nutrition, health conditions, hormonal imbalances, and genetic factors not accounted for in the simple formula can affect accuracy.

Q5: Should I be concerned if my child's height differs significantly from the prediction?
A: Significant deviations (more than 8-10 cm) may warrant consultation with a pediatrician or endocrinologist to rule out growth disorders.
