1. What is the EER Equation for Children in South Africa?

The Estimated Energy Requirement (EER) equation for children in South Africa calculates daily energy needs based on age, physical activity level, weight, and height. It provides a more accurate assessment of energy requirements for this specific population.

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 adjusted for age, plus additional energy requirements based on physical activity level and body size.

3. Importance of EER Calculation

Details: Accurate EER estimation is crucial for nutritional planning, growth monitoring, and preventing both undernutrition and obesity in South African children.

4. Using the Calculator

Tips: Enter age in years, physical activity level (typically between 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 for children?
A: Sedentary children: 1.0-1.4; moderately active: 1.5-1.8; very active: 1.9-2.5.

Q2: What are normal EER values?
A: EER varies greatly by age, size and activity level. For reference, a 10-year-old might need 1600-2400 kcal/day.

Q3: When should measurements be taken?
A: Weight and height should be measured in the morning, with light clothing and no shoes for accuracy.

Q4: Are there limitations to this equation?
A: This equation is specific to South African children and may not be accurate for other populations or children with special health conditions.

Q5: How often should EER be recalculated?
A: EER should be recalculated every 3-6 months for growing children, or whenever weight or activity level changes significantly.
