This is one of the most frequently asked questions in my practice at a well child check. Obviously, genetics are the most important factor in determining a child’s final height. As I tell my shorter families, “You do not get a Great Dane from two Chihuahuas”.
My Concerns
As a pediatrician, I am not concerned with trying to predict final height, but rather watching for growth problems and addressing growth concerns. There are three indicators that would warrant further evaluation.
Indicator 1
Is the child growing enough per year? This is called growth velocity. Healthy non-pubertal growth is at least 2-2 ½ inches/year.
Indicator 2
Is the child growing correctly for his/her genetics? There is a calculation based on parental heights called the Mid-Parental Target Height (MPTH). If the child falls out of the predicted height zone, he might warrant further evaluation.
Indicator 3
Is the child below the third percentile for his or her predicted final height?
Physicals
Usually, the first step in the work up for growth concerns involves an x-ray and a simple blood test. Sometimes, a consult by a growth specialist (endocrinologist) is needed. It is important to recognize growth issues early, so please schedule yearly physicals for your children.
