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.
