Which growth chart should be used for children aged 2 years and older?

For children aged 2 years and older, the CDC growth chart is the most appropriate option. These charts are specifically designed to assess the growth patterns of children in the United States based on a representative population sample. They include data on weight-for-age, height-for-age, body mass index (BMI)-for-age, and weight-for-height, allowing pediatricians to evaluate growth in children as they transition from infancy to childhood.

The CDC growth charts are widely used in clinical settings due to their alignment with the growth patterns observed in the U.S. population, making them a reliable tool for monitoring growth in children ages 2 to 19. They help identify children who may be underweight, overweight, or have growth disorders, giving healthcare providers a standard measure to compare against.

Growth charts from organizations like the WHO are typically recommended for younger children under 2 years of age, as they were created from data reflecting children who were breastfed and represent an international population rather than a specific national group. The other options mentioned are not standardized for general use in monitoring children's growth in the same way that the CDC charts are. Therefore, using the CDC growth chart ensures that a consistent and appropriate measure is applied for assessing growth in children aged 2 years and older.
