16 tools

• 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 tables as the calculator on usegrowo.com. Returns no interpretation.

• 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'.

• 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 years), the split the CDC advises. From 24 months the result also carries the…

• 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. Band crossings are the unit that matters — one is common while a child settles…

• 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 over time, but how big they were on the day they were born given how long the…

• 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 choosing the age at which to plot growth. Takes the birth date and the…

• 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 either side. Use it for 'how tall will my child be', 'mid-parental height' and…

• 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 weight loss percentage' and 'has my baby regained birth weight'. It is…

• 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'. Weight in grams, length and head circumference in centimetres, dates as…

• 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 the usual measure for older children. It returns the number and does not place…

• 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 birth date into an age in months. This is the age since birth, not the age…

• 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. For '7 lb 4 oz' pass value 7, unit lb, extra 4; for '2 ft 3 in' pass value 2…

• 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. It converts the number and does not say what it means for a child.

• 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 Development Study — a child inside a window is within the normal range.
