It is particularly useful in working up growth abnormalities and can indicate a delay in onset of puberty.
For both boys and girls there are two sets of charts: one for infants ages 0 to 36 months and another for ages 2 and above. Children with failure to thrive usually have a weight that is below the 3rd or 5th percentile for their age and a declining growth velocity (meaning they are not gaining weight as expected).
The 2000 CDC growth charts - a revised version of the 1977 NCHS growth charts - are the current standard tool for health care providers and offer 16 charts (8 for boys and 8 for girls), of which BMI-for-age is commonly used for aiding in the diagnoses of childhood obesity.

It is desired that a score of 99 correspond to the 99th percentile; The 99th percentile in a normal distribution is 2.3263 standard deviations above the mean; 99 is 49 more than 50—thus 49 points above the mean; 49/2.3263 = 21.06. Normal curve equivalents are on an equal-interval scale.
Birth weight is the body weight of a baby at their birth. [1] The average birth weight in babies of European and African descent is 3.5 kilograms (7.7 lb), with the normative range between 2.5 and 4.0 kilograms (5.5 and 8.8 lb). [2] On average, babies of Asian descent weigh about 3.25 kilograms (7.2 lb).
