Which growth chart should be used for children over 2 years of age?

The CDC growth chart is the recommended tool for tracking the growth of children over 2 years of age in the United States. These charts are based on a large, representative sample of the U.S. population and are designed to assess and monitor the growth patterns of healthy children and adolescents.

The use of the CDC growth chart allows healthcare professionals to compare a child's growth against national standards, facilitating the early detection of growth abnormalities and enabling appropriate interventions. The charts include percentiles that indicate how a child's measurements compare with those of peers, which is crucial for ongoing assessment of growth over time.

In contrast, the WHO growth chart is mainly intended for children under 2 years of age and is based on breastfeeding norms from multiple countries. The FDA and APA do not have growth charts specifically for pediatric growth assessment.
