1. What is a Tanner Stage Height Calculator?

Definition: This calculator estimates the predicted height based on base height, growth rate per Tanner stage, and current Tanner stage.

Purpose: It helps medical professionals and parents predict growth during puberty based on the Tanner stages of development.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( Height \) — Predicted height (meters, m)
• \( Base\ Height \) — Initial height (meters, m)
• \( Growth\ Rate \) — Height increase per stage (meters per stage)
• \( Stage \) — Tanner stage (1-5)

Explanation: The base height is added to the product of growth rate and Tanner stage to predict current height.

3. Importance of Tanner Stage Height Calculation

Details: Tanner staging helps monitor pubertal development and predict growth potential, important for assessing normal development and identifying potential growth disorders.

4. Using the Calculator

Tips: Enter the base height in meters, growth rate (default 0.05 m/stage), and Tanner stage (1-5). All values must be valid (stage between 1-5).

5. Frequently Asked Questions (FAQ)

Q1: What are Tanner stages?
A: Tanner stages are a scale of physical development in children, adolescents, and adults, divided into 5 stages based on secondary sex characteristics.

Q2: What's a typical growth rate per stage?
A: Growth rates vary, but average is about 5-7 cm (0.05-0.07 m) per stage during puberty.

Q3: When should I be concerned about growth?
A: If growth deviates significantly from predicted patterns or if the child is below the 3rd percentile for age and sex.

Q4: How do I determine the Tanner stage?
A: Tanner stage should be determined by a healthcare professional through physical examination.

Q5: Does this calculator account for genetic factors?
A: No, this is a basic calculator. For comprehensive growth assessment, consult a pediatric endocrinologist.
