peak growth velocity
The maximum rate of linear growth during the adolescent growth spurt, typically occurring around ages 12-13 in females and 14-15 in males.
Full Definition
Peak growth velocity represents the highest growth rate achieved during puberty, usually ranging from 8-12 cm per year. This milestone typically occurs during Tanner stage 3-4 and coincides with peak height velocity on growth charts. Understanding peak growth velocity timing is crucial for predicting final adult height, timing orthopedic interventions, and counseling families about normal versus abnormal growth patterns. The timing and magnitude of peak growth velocity can be influenced by nutrition, chronic illness, and genetic factors.
Usage
Usage note: Often abbreviated as PGV in clinical notes; interchangeable with peak height velocity (PHV).
