Triponderal Mass Index rather than Body Mass Index in discriminating high adiposity in Brazilian children and adolescents.

Introduction: body mass index (BMI) is used worldwide to track excess weight; however, it has limitations in predicting body fat percentage (BF%). Triponderal mass index (TMI) has been studied as an alternative indicator to predict BF%.

Objective: to compare BMI and TMI as predictors of BF% and develop TMI cutoff points for screening high adiposity in Brazilian children and adolescentes.
