Age-Related Stature Loss
Definition
The decrease in living stature with age due to intervertebral disc compression and vertebral remodeling, approximately 0.10-0.12 cm per year after age 30. The Giles-Hutchinson 1991 correction adds 0.06 x (age - 30) cm to the skeletal estimate to approximate living maximum stature for older individuals.

Common questions
Why apply a correction to a stature estimate derived from bone at all?+
Long-bone regression equations estimate the stature a person had as a healthy adult, but the goal is often to match a living maximum stature on record such as a driver's license, so the age-related loss since young adulthood has to be added back.
Does this correction matter for a skeleton of a young adult?+
Little to none, since the correction is proportional to years past age 30. It becomes significant only for skeletal remains estimated to belong to older individuals, where several centimetres of stature loss can otherwise cause a mismatch with missing-person records.
