growth velocity
The rate of linear growth over a specified time period, typically expressed as centimeters per year.
Full Definition
Growth velocity refers to the speed of linear growth measured over a specific time interval, usually calculated as centimeters gained per year. In adolescent medicine, growth velocity assessment is crucial for evaluating normal pubertal development, identifying growth disorders, and monitoring response to treatments. Normal prepubertal growth velocity is approximately 5-6 cm/year, while peak pubertal growth velocity can reach 8-12 cm/year in girls and 10-14 cm/year in boys during their growth spurts.
Usage
Usage note: Specify time period when documenting growth velocity measurements; distinguish from peak height velocity which refers to maximum growth rate during puberty.
