growth velocity
Rate of linear growth measured over a specific time period, typically expressed as centimeters per year.
Full Definition
A critical parameter in pediatric endocrinology that measures the rate of height increase over time, usually calculated as centimeters gained per year. Growth velocity is more diagnostically useful than single height measurements as it reflects the dynamic process of growth. Normal growth velocity varies by age, with highest rates in infancy and during pubertal growth spurts. Decreased growth velocity may indicate growth hormone deficiency, chronic illness, or other growth disorders. Accurate measurement requires precise height measurements taken at least 6-12 months apart using standardized techniques.
Usage
Usage note: Always specify the time period over which velocity was calculated.
