How Tall Will Your Child
Remember when our parents had us stand up against
a wall and make a mark with a pencil to see how much we had grown? And then
wondering exactly how tall we would eventually become?
A child's adult height is influenced by a number
of factors, including genetics, sex, and overall health and nutrition. Genetics
and the child's gender account for 70% of what goes into deciding how tall
a child will be. The other 30% comes from environmental factors, such as
nutrition, exercise, and any underlying health problems.
There are a number of methods for predicting adult
height. Probably the most accurate is the technique employed by pediatricians
and endocrinologists. Using a reference entitled Radiographic Atlas
of Skeletal Development of the Hand and Wrist written by Greulich
and Pyle , a reasonable good estimate of a youngster's height at maturity
can be made knowing the child's
age and chronological age.
Another approach is based on the fact that most
healthy children will grow to a height that is somewhere between their mother's
and father's heights. Using these factors, this method predicts adult height
by adding the parents' heights together, dividing by two, then adding three
inches for a boy (or subtracting three for a girl). While this method is
fairly accurate, the child's ultimate height can vary by as much as five
inches above or below this calculation.
The method you are about to use was developed by
Drs. Harry Khamis and Alex Roche working at Wright State University and published
in Pediatrics , the official publication of The American
Academy of Pediatrics in 1994. These researchers developed a method
that eliminated the need for a bone age x-ray. The "Khamis-Roche Method"
is fairly accurate (within an inch and a half of actual growth) but is only
reliable in children who have no other known medical problems.
This height calculator is not intended to
replace your doctor's advice. It is extremely important that you share with your child's pediatrician any concerns you have about your youngster's growth. This way, he or she
can follow your child's development carefully and recommend further evaluation when necessary.
Another method used to calculate height
is the gray method. Try this one too!
