Which data sources contributed to validating the Fenton chart?

• A. NICHD Network data; CDC growth charts; intrauterine and postnatal growth data
• B. WHO growth standards
• C. NHANES data
• D. None of the above

Answer: (A)

Understanding how a fetal-to-neonatal growth reference is validated requires data that cover how weight relates to gestational age both before birth and at birth, and how newborn weights align with established postnatal references. The Fenton chart is built to describe birth weight-for-gestational age in preterm infants, and validating it needs large, diverse datasets that reflect real fetal growth patterns and actual newborn measurements. The NICHD Network data provide a large, multicenter sample of neonatal weights with accurate gestational-age dating, ensuring the chart’s percentile curves reflect real preterm populations. The CDC growth charts offer a well-established reference for weight-for-age in the term population, allowing the preterm chart to be anchored to a familiar postnatal standard and checked for continuity as infants grow. Data detailing intrauterine (fetal) growth and postnatal growth are essential to connect fetal weight trajectories with birth-weight outcomes and to validate how those trajectories translate into postnatal growth patterns. Other sources like WHO growth standards focus on term infants and older children, not the preterm birth weight-for-gestational-age relationship, and NHANES data are health survey datasets not specifically tailored to validating neonatal birth weights by gestational age. Therefore, the combination of NICHD Network data, CDC growth charts, and intrauterine plus postnatal growth data best supports the validation of the Fenton chart.
