Tools (16)
| Name | Description | Schema |
|---|---|---|
growth_percentile | Where one measurement of a child sits on the WHO or CDC growth reference chart. Returns the percentile, the z-score and the 3rd/15th/50th/85th/97th percentile values at that age, using the same LMS ta | typed |
growth_reference_range | The 3rd/15th/50th/85th/97th percentile values for a given age and sex — the reference band itself, with no child's measurement involved. Use this to answer 'what is normal for this age'. | typed |
zscore_percentile | Converts a z-score (standard deviations from the median) to a percentile and a percentile to a z-score on the normal curve, the relationship growth charts use. Pass exactly one of zScore or percentile | typed |
bmi_percentile | Computes BMI from weight and height, then places it on the BMI-for-age chart for the child's sex and age: the WHO standards under 24 months, the CDC 2000 growth charts from 24 months to 240 months (20 | typed |
growth_trend | What moved between two measurements of the same child: the percentile and z-score at each point, how far the position shifted, and how many of the drawn 3rd/15th/50th/85th/97th lines were crossed. Ban | typed |
birth_size_percentile | Where a birth measurement sits on the Olsen 2010 intrauterine curves, for the number of completed weeks of pregnancy. This answers a different question from the growth charts: not how a child grows ov | typed |
corrected_age | The corrected age of a baby born before 37 weeks: the age since birth minus the weeks the baby was early. Use it for 'what is my preemie's corrected / adjusted age', for reading milestones, and for ch | typed |
development_milestones | WHO motor-development windows that are open, already closed or not yet due at a given age, plus the nearest CDC well-child checkpoint months. Windows are 1st–99th percentile ranges from the WHO Motor | typed |
target_height | The adult height a child is expected to reach, estimated from both parents' heights with Tanner's mid-parental method: (mother + father +13 cm for a boy, -13 cm for a girl) / 2, with a range of 8.5 cm | typed |
newborn_weight_change | How far a baby's weight is from the birth weight: the change in grams and in percent, and whether the baby is back at or above birth weight. Use it for 'how much weight has my newborn lost', 'newborn | typed |
growth_velocity | How fast a child grew between two measurements: the change, and the rate per day, per week and per 30 days. Use it for 'how many grams a day is my baby gaining' and 'how many cm did my child grow'. We | typed |
ponderal_index | The ponderal index (Rohrer's index) from weight and length: 100 x weight in grams / length in cm cubed, with the same quantity in kg per cubic metre. It is a newborn proportion measure; BMI-for-age is | typed |
child_age | The exact calendar age from a birth date: whole years, months and leftover days, plus the total in months, weeks and days. Use it for 'how old is my baby in months', 'age in weeks' and for turning a b | typed |
convert_measurement | Converts a weight (kg, g, lb, oz) or a length (cm, m, in, ft) to every common unit, so a measurement quoted in pounds and ounces or feet and inches can go into the growth tools, which take kg and cm. | typed |
search | Search Growo's physician-written articles and calculators on baby and child growth, percentiles, growth charts, premature babies (corrected age), head circumference, sleep, feeding and development. Re | typed |
