Schofield Equation Approximation:
| From: | To: |
The Schofield equation approximation estimates Total Daily Energy Expenditure (TDEE) for children aged 3-10 years. It provides a calculation of daily calorie needs based on weight and activity level.
The calculator uses the Schofield equation approximation:
Where:
Explanation: The equation calculates basal metabolic rate then multiplies by activity factor to estimate total daily energy expenditure.
Details: Accurate TDEE estimation is crucial for determining appropriate calorie intake for growth, maintaining healthy weight, and nutritional planning for children.
Tips: Enter weight in kilograms and select appropriate activity factor based on the child's daily activity level. All values must be valid (weight > 0).
Q1: What age group is this calculator designed for?
A: This calculator is specifically designed for children aged 3-10 years using the Schofield equation approximation.
Q2: How accurate is this calculation?
A: While the Schofield equation provides a good estimate, individual variations in metabolism and activity patterns may affect accuracy.
Q3: What activity factor should I choose?
A: Select based on the child's typical daily activity: Sedentary (little exercise), Lightly Active (light exercise 1-3 days/week), Moderately Active (moderate exercise 3-5 days/week), Very Active (hard exercise 6-7 days/week), or Extra Active (very hard exercise and physical job).
Q4: Should this be used for medical purposes?
A: This calculator provides estimates only. For medical nutrition therapy or specific health conditions, consult with a healthcare professional or registered dietitian.
Q5: How often should TDEE be recalculated?
A: TDEE should be recalculated periodically as the child grows, weight changes, or activity levels significantly change.
