Obesity and Overweight in Children

The Centers for Disease Control and Prevention (CDC) defines overweight for adults as having a body mass index (BMI) of 25.0–29.9 percent and obesity as having a BMI of 30.0 and above.

For children and adolescents (aged 2–19 years), the BMI value is plotted on the CDC growth charts to determine the corresponding BMI-for-age percentile, so that overweight is defined as a BMI at or above the 85th percentile and lower than the 95th percentile, and obesity is defined as a BMI at or above the 95th percentile for children of the same age and sex.
