Introduction: The height measurements in the elderly are associated with several problems. In this study
we used a model to predict of the Iranian people aged height from age, shin length and forearm length.
Methods: A total 165 aged people ≥60 years were randomly selected based on medical record number of
about 800 eligible older people who lived in Kahrizak Charity Foundation. Standing height, shin length
and forearm length were measured. Data from 99 participants were used to creat a predicting multivariate
linear regression model for estimation of standing height of older men and women. The data of the rest
66 participants were used for models testing.
Result: The following equations were created:
Men height = 78.928+ (1.430× shin length) + (0.817×forearm length)-(0.176×age)
The height of women = 71.694+ (1.414×shin length) + (1.084× forearm length)-(0.277× age)
R2
were calculated as 0.63 for men and 0.52 for women. Error of estimation was +0.44 cm and it was -
0.16cm and +1.09cm for men and women respectively. Estimated heights were not significantly different
from standing statures.
Conclusion: height was predictable from shin length and for forearm lengths and also age with a
relatively small error in the estimation among Iranian older people. The error of model is more in women
than men.
