The pediatrician is also accustomed to say when carrying out health assessments what percentile the child corresponds to. But what are the growth percentiles? And how are they calculated?
The percentile or, more precisely, the percentile diagrams are the unit of measurement that is used to determine how the child’s growth in weight and height is progressing. They are made by taking groups of 1000 children of the same age as a term of comparison. Children are divided according to weight and height and are then placed in 100 subgroups each consisting of 10 children. Each group is a centile and each centile is representative of one percent of the infant population of the age taken into consideration.
What are the average measurements?
In the first centile there are the smaller children, in the centile the taller and larger ones. Most of the infant population is positioned between the 25th and 75th percentile. Children in the 50th centile are medium-sized children.
The use of percentile diagrams allows you to determine if the growth rate is acceptable e therefore to exclude problems related to physical development: if the child is between the third and ninety-seventh centile he still has an adequate growth, even if between the two extremes there is a significant difference (which in any case is often influenced by genetics). If the child is permanently below or above the two thresholds, it is advisable to think about the existence of a problem.
Be careful not to be too alarmed, however, if the child “is not in the average”. Each child has his own personal growth rate which is highlighted, in fact, by the growth curve. The pediatrician, looking at the curve, can assess physical development and identify any significant changes.
