Tri-Ponderal Mass Index vs Body Mass Index in Estimating Body Fat During Adolescence.

ABSTRACT:

Importance

Body mass index (BMI) is used to diagnose obesity in adolescents worldwide, despite evidence that weight does not scale with height squared in adolescents. To account for this, health care providers diagnose obesity using BMI percentiles for each age (BMI z scores), but this does not ensure that BMI is accurate in adolescents.

Objective

To compare the accuracy of BMI vs other body fat indices of the form body mass divided by heightn in estimating body fat levels in adolescents.

Design, setting, and participants

Cross-sectional data from the 1999 to 2006 US National Health and Nutrition Examination Survey were analyzed between September 2015 and December 2016.

Main outcomes and measures

Dual-energy x-ray absorptiometry and anthropometric data were use
