Description

The Centers for Disease Control (CDC) published data on the body dimensions of pediatric patients in 2000. This included data on the height of boys aged from 2 to 20 years.


Equations derived in JMP

 

predicted height in centimeters =

= (A * ((age in months)^3)) + (B * ((age in months)^2)) + (C * (age in months)) + D

 

NOTE: The tables should be validated prior to clinical use.
