height age
The age at which a child's current height would be at the 50th percentile on growth charts.
Full Definition
Height age represents the age at which a child's current stature would correspond to the 50th percentile (median) on standard growth charts for their sex. This parameter helps assess the degree of growth delay or advancement relative to normal expectations. Height age is calculated by finding the intersection of the child's current height with the 50th percentile line on growth charts. When compared to chronological age, height age provides insights into growth patterns and potential for catch-up growth. A height age significantly below chronological age may indicate growth hormone deficiency, constitutional delay, or other growth disorders requiring evaluation.
Usage
Usage note: Always compare with chronological and bone age for comprehensive growth assessment.
