1. What is the EER Equation for Children?

The Estimated Energy Requirement (EER) equation for school-age children calculates the average dietary energy intake needed to maintain energy balance in healthy children. It accounts for 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 needs (age component), physical activity (PA multiplier), and body size (weight and height components).

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for ensuring children receive adequate nutrition for growth and development while avoiding excessive calorie intake that could lead to obesity.

4. Using the Calculator

Tips: Enter age in years (0-18), select appropriate physical activity level, weight in kg, and height in meters. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What are the PA level categories?
A: Sedentary (1.0) = no activity; Low Active (1.13) = some light activity; Active (1.26) = 60+ min moderate activity daily; Very Active (1.42) = 60+ min vigorous activity daily.

Q2: What are typical EER values for children?
A: EER varies by age and size, but generally ranges from 1200-2500 kcal/day for school-age children.

Q3: How often should EER be recalculated?
A: EER should be recalculated whenever a child's weight, height, or activity level changes significantly (typically every 3-6 months).

Q4: Are there limitations to this equation?
A: This equation is for healthy school-age children. It may not be accurate for children with medical conditions affecting metabolism.

Q5: Should this be used for meal planning?
A: EER provides an estimate but individual needs may vary. Consult a dietitian for personalized nutrition advice.
