Key facts
- Body mass index (BMI) [Percentile]
- Body mass index
- The percentile of a patient's body mass index indicates the relative position of the patient's BMI number among a given population. For adults 20 years old and older, BMI is calculated using standard weight status categories that are the same for all ages and for both men and women. For children and teens, on the other hand, the interpretation of BMI is both age- and sex-specific. This term does not specify whether the interpretation of percentile is based on age and sex or not.
