Final answer:
The CDC recommends the BMI-for-age growth chart to assess weight in relation to stature for children aged 2 to 20 years, as it provides a comprehensive measure of body fat based on both height and weight.
Step-by-step explanation:
The growth chart currently recommended by the Centers for Disease Control and Prevention (CDC) for assessing weight in relation to stature in children ages 2 to 20 years is the BMI-for-age growth chart. This growth chart helps healthcare providers determine if a child is underweight, a healthy weight, overweight, or obese compared with other children of the same age and sex by using Body Mass Index (BMI), which is a measure of body fat based on height and weight. This method is preferred over others, like weight-for-age or stature-for-age, because it provides a more comprehensive assessment of a child's growth patterns and potential health risks associated with abnormal weights for their stature.
