1. What is the EER Equation?

The Estimated Energy Requirement (EER) equation calculates the average dietary energy intake needed to maintain energy balance in healthy school-aged children based on their age, physical activity level, weight, and height.

2. How Does the Calculator Work?

The calculator uses the EER equation:

Where:

• \( A \) — Age in years
• \( PA \) — Physical Activity Level (dimensionless)
• \( W \) — Weight in kilograms
• \( H \) — Height in meters

Explanation: The equation accounts for basal metabolic rate and additional energy needs based on physical activity level and body size.

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for ensuring children receive adequate nutrition for growth and development while maintaining a healthy weight.

4. Using the Calculator

Tips: Enter age in years, physical activity level (typically 1.0-2.5), weight in kg, and height in meters. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are typical PA values?
A: Sedentary = 1.0, Low active = 1.13-1.26, Active = 1.42-1.58, Very active = 1.73-2.1 depending on age and gender.

Q2: What age range is this equation for?
A: This equation is specifically designed for school-aged children (approximately 6-18 years).

Q3: How accurate is this estimate?
A: It provides a population-level estimate. Individual needs may vary by ±20% due to metabolic differences.

Q4: Should this be used for overweight children?
A: For overweight children, consult a dietitian as adjustments may be needed based on growth goals.

Q5: How often should EER be recalculated?
A: Recalculate every 3-6 months for growing children or with significant changes in weight or activity level.
