pubertal growth spurt
Period of accelerated linear growth during adolescence, representing the fastest growth phase after infancy.
Full Definition
A characteristic phase of rapid height increase that occurs during puberty, typically lasting 2-4 years and representing the second-fastest period of growth in human development after infancy. The growth spurt begins earlier in girls (around age 10-11) than boys (around age 12-13) and coincides with increasing sex hormone production. Peak height velocity during this period can reach 8-12 cm per year. Understanding the timing and magnitude of the pubertal growth spurt is crucial for evaluating normal versus abnormal growth patterns, predicting final adult height, and timing growth-promoting interventions.
Usage
Usage note: Document peak height velocity when measurable during this period.
