growth velocity
Rate of linear growth measured over a specific time period in pediatric patients.
Full Definition
Growth velocity refers to the rate of linear growth, typically expressed as centimeters per year, and is a critical parameter for monitoring pediatric patients with rheumatic diseases. Chronic inflammatory conditions and their treatments, particularly corticosteroids, can significantly impact growth velocity by affecting growth hormone production, nutritional status, and bone metabolism. Regular measurement and plotting of height velocity on appropriate growth charts helps identify growth suppression early in the disease course. Normal growth velocity varies by age and pubertal stage, with the highest rates occurring during infancy and adolescent growth spurts. Monitoring growth velocity is essential for optimizing treatment regimens and determining the need for growth-promoting interventions.
Usage
Usage note: Always specify time period over which growth velocity is calculated.
