Track Health of Children

This service has two parts, both offered for free!

• A calculator. Enter a few simple measurements for a child, and get an estimate of how well nourished they are, using models developed by the World Health Organization (WHO). No account needed.
• A database. The same estimates, and it also tracks children over time and produces reports. This part needs an account, and a database you create for your organization.

Please send us your feedback.

Scoring with WHO standards

WHO publishes two sets of growth standards, each built from a separate group of children, and this site uses both. A child's age decides which one scores them, and the two do not score the same things.

• Child Growth Standards (ages 0-5 years). Every score: weight-for-age, length or height-for-age, weight-for-length or height, BMI-for-age, head circumference, arm circumference and the two skinfolds.
• Growth reference (ages 5-19 years). Weight-for-age, height-for-age and BMI-for-age only. Weight-for-height is not defined above five, and BMI-for-age takes its place. Head circumference and the skinfolds stop at five. Weight-for-age stops at ten, since past that age a weight says little without a height beside it.

Above age nineteen no standard applies, and nothing is scored.

A score far beyond anything a real child reaches usually means a wrong birth date rather than a child in trouble, so check the birth date first.
