midparental height
Calculated genetic height potential based on parents' heights, used to assess growth expectations.
Full Definition
Midparental height is a calculation used to estimate a child's genetic height potential based on their parents' statures. For boys, it is calculated as (father's height + mother's height + 13 cm) ÷ 2; for girls, it is (father's height + mother's height - 13 cm) ÷ 2. The 13 cm adjustment accounts for the average height difference between males and females. This calculation provides a target height range (typically ±10 cm) that represents the expected adult height based on genetic factors. Midparental height helps clinicians distinguish between pathological short stature and familial short stature, guiding decisions about further investigation and treatment.
Usage
Usage note: Include the ±10 cm range when documenting; verify accuracy of parental height measurements.
