Growth Velocity

Growth velocity is a simple and reproducible measure that evaluates change in rate of growth over a specified time period: it generally is expressed in centimeters per year. It is a more sensitive way of assessing growth failure or slowed growth, and is particularly helpful in the early identification of children with undernutrition.

Standards. Figures 2-13 and 2-14 are growth velocity charts, based on growth data of North American children.1' Additional reference data for 1-month increments

Interpretation. Increments in growth may occur at different times but follow a similar sequence in most instances. Growth velocity charts are constructed from and used for longitudinally obtained incremental data. They detect changes in growth status more quickly
