What is weight by age?

Weight by age refers to the expected weight range for a person of a specific age, gender, and height. The WHO growth charts provide standardized references for monitoring growth and development in children and adults.

Tracking weight by age helps identify potential growth issues, malnutrition, or other health concerns. The charts account for normal variations in growth patterns across different populations.

Note: The WHO growth charts are based on data from various countries and may not perfectly match local populations. Always consult with a healthcare professional for personalized advice.

Weight by age formula

The calculator uses the following formulas based on the WHO growth charts:

For children (0-18 years):

Weight (kg) = (Height (cm) - 100) × 0.9 × (1 + 0.01 × Age)

Minimum weight = Weight × 0.85

Maximum weight = Weight × 1.15

For adults (19+ years):

Weight (kg) = 22 × (Height (m))²

Minimum weight = Weight × 0.9

Maximum weight = Weight × 1.1

These formulas provide a general estimate. Individual variations may occur due to genetics, lifestyle, and other factors.

FAQ

What is the difference between weight by age and BMI?

Weight by age provides a general weight range based on age and gender, while BMI (Body Mass Index) measures body fat based on height and weight. BMI is more commonly used for adults, while weight by age charts are more appropriate for children.

When should I be concerned about a child's weight?

You should consult a healthcare professional if a child's weight falls consistently below the minimum range on the growth chart for more than a few months, or if there are other signs of malnutrition or growth issues.

Can weight by age charts be used for adults?

Yes, the charts can provide a general reference for healthy weight ranges in adults, but they should be used in conjunction with other health metrics for a complete assessment.
