health.child-growth-zscore Calculator
Calculates WHO growth z-scores (WAZ, HAZ, WHZ) for infants and children from weight, height, and age, and classifies nutritional status. Z-score below −2 defines stunting (HAZ), wasting (WHZ), or underweight (WAZ) — the WHO standard for malnutrition assessment.
Inputs
Child Weight Kg
Body or object weight. For health calculators, usually in kg or lbs.
Child Height Cm
Vertical measurement. For health calculators, typically standing height without shoes.
Age Months
Age in completed years. Many health and fitness formulas adjust for age.
Sex
Reference formula or conversion factor shown for context.
Results
weight z-score (approx)
Number of standard deviations a value is from the mean. |z| below 2: within normal range. |z| above 2: in the outer 5% of the distribution. |z| above 3: in the outer 0.3%.
height/length z-score (approx)
Number of standard deviations a value is from the mean. |z| below 2: within normal range. |z| above 2: in the outer 5% of the distribution. |z| above 3: in the outer 0.3%.
BMI
BMI (body mass index) = weight (kg) / height squared (m^2). Under 18.5: underweight. 18.5-24.9: normal. 25-29.9: overweight. 30+: obese. Does not distinguish muscle from fat.
weight status
Current state of the system, process, or metric — typically pass/fail, healthy/warning/critical, or a descriptive classification.
stunting
Sample size or count used in the calculation.
WHO z-score < -2
Number of standard deviations a value is from the mean. |z| below 2: within normal range. |z| above 2: in the outer 5% of the distribution. |z| above 3: in the outer 0.3%.
