Galloway et al developed an equation for estimating the height of an older adult based on the loss of height that occurs with age. The author is from the University of Arizona in Tuscon.
Patient selection: adult
The peak height of early adulthood is maintained until about age 45, after which there is a slow loss of height. The average rate of loss after age 45 years was 0.16 per year.
Parameters:
(1) age in years
(2) peak early adult height in centimeters
height at a given age in cm =
= (peak height in cm) - (0.16 * ((age in years) - 45))
Other factors such as vertebral crush fractures and increasing kyphosis can further reduce the height with aging.
