How to Use the Energy Requirement Calculator

1. Enter Age: Input the child's age in months (for ages 0-36 months) or years (for ages above 3 years).
2. Select Age Unit: Choose either "Months (0-36)" or "Years (>3)" from the dropdown menu.
3. Enter Weight: Provide the child's weight in kilograms (kg).
4. Enter Height (Optional): If the child is older than 3 years, input height in meters (m).
5. Select Gender: Choose either "Male" or "Female."
6. Choose Physical Activity Level:
   • Sedentary (1.0-1.4)
   • Low Active (1.4-1.6)
   • Active (1.6-1.9)
   • Very Active (1.9-2.5)
7. Click the Calculate Button: Press the "Calculate" button to compute the Estimated Energy Requirement (EER) in kcal/day.
8. View Results: The calculated energy requirement will be displayed below the button.

Additional Information

• The calculations are based on age-specific formulas recommended by pediatric nutrition guidelines.
• The "Physical Activity Coefficient" section provides details on how physical activity affects EER.
• The "Formulas" section contains reference images for energy requirement calculations.

For clinical use, always verify values with professional guidelines.

Physical Activity Coefficient

• PA indicates the physical activity coefficient:
• For boys:
• PA = 1.00 (sedentary, estimated physical activity level 1.0-1.4)
• PA = 1.13 (low active, estimated physical activity level 1.4-1.6)
• PA = 1.26 (active, estimated physical activity level 1.6-1.9)
• PA = 1.42 (very active, estimated physical activity level 1.9-2.5)
• For girls:
• PA = 1.00 (sedentary, estimated physical activity level 1.0-1.4)
• PA = 1.16 (low active, estimated physical activity level 1.4-1.6)
• PA = 1.31 (active, estimated physical activity level 1.6-1.9)
• PA = 1.56 (very active, estimated physical activity level 1.9-2.5)
