Age Context

For children and teenagers (under 18), BMI is interpreted differently. Unlike adults, BMI for youth is age- and sex-specific, using percentiles from CDC growth charts. For a 15-year-old boy at 6ft 7in and 300lbs, a BMI of 33.8 would be evaluated using pediatric growth percentiles rather than the adult obese category.
