What is a major advantage of the Fenton growth chart?

• A. It allows tracking of growth from 22 weeks gestational age up through 10 weeks post term age
• B. It tracks only term newborns
• C. It is based on longitudinal data
• D. It replaces the Lubchenco chart

Answer: (D)

The major advantage is that the Fenton growth chart replaces the older Lubchenco chart with a more current, representative reference for preterm infants. It draws from a larger, more diverse data set and covers a wide span of gestational ages (from about 22 weeks gestation up to roughly 50 weeks postmenstrual age), providing more accurate and applicable growth centiles for weight, length, and head circumference as babies grow. This updates and standardizes how prematurity-related growth is tracked in modern NICU populations, making assessments more reliable than using the Lubchenco charts—which are older and based on a smaller, less representative sample. The other options don’t fit because the Fenton chart is not limited to term newborns, it is specifically designed for preterm growth across a wide age range, and its advantage isn’t simply that it uses longitudinal data.
