peak height velocity
Maximum rate of height increase during the adolescent growth spurt, typically occurring mid-puberty.
Full Definition
Peak height velocity (PHV) represents the fastest rate of linear growth during adolescence, typically occurring during Tanner stage 3-4 in both males and females. PHV usually occurs around age 12 in girls and age 14 in boys, with average velocities of 8-9 cm/year and 9-10 cm/year respectively. This milestone is crucial for timing orthopedic interventions, nutritional counseling, and sports participation decisions. PHV timing can be affected by nutritional status, chronic illness, and hormonal factors. Monitoring PHV helps clinicians assess normal pubertal progression and identify potential growth disorders requiring intervention.
Usage
