growth velocity
Rate of linear growth measured over a specific time period, crucial for assessing pediatric health.
Full Definition
Growth velocity refers to the rate at which a child grows in height over a defined period, typically expressed as centimeters per year or as a percentile change on growth charts. In pediatric gastroenterology, growth velocity is a critical indicator of nutritional status and overall health. Decreased growth velocity may be the first sign of chronic gastrointestinal disease, malnutrition, or malabsorption. Normal growth velocity varies by age, with infants and adolescents typically showing the highest rates. Monitoring growth velocity helps clinicians assess the effectiveness of treatments and interventions for gastrointestinal disorders.
Usage
Usage note: Often expressed with units (cm/year) in clinical documentation.
