pubertal growth spurt
Rapid acceleration in linear growth velocity that occurs during adolescence, typically lasting 2-3 years.
Full Definition
The pubertal growth spurt represents the period of most rapid growth in height and weight during the adolescent years, typically beginning around age 10-11 in girls and 12-13 in boys. Peak height velocity averages 8-9 cm/year in girls and 10-11 cm/year in boys. This growth pattern is driven by increased growth hormone and sex hormone production during puberty. Understanding normal pubertal growth patterns is essential for identifying growth disorders, timing orthopedic interventions, and providing appropriate nutritional guidance. Growth velocity charts are used to track and assess normal versus abnormal growth patterns during this period.
Usage
Usage note: Distinguish from 'growth velocity' which is the rate of growth, while 'growth spurt' refers to the overall period of acceleration.
