Abstract

Introduction: Since 2017, number of studies involving nutritional status of adolescents using a novel parameter named tri-ponderal mass index (TMI) is soaring high. The concept of TMI was formulated to substitute body mass index (BMI) in case of adolescent population. The present study aims to find TMI values of school-going adolescent girls (aged 10 to 19 years). It also aims to compare the association of TMI and BMI with mid-upper arm circumference (MUAC) of the subjects.

Methods: Height, weight and MUAC were measured using standard procedures. The BMI and TMI were accordingly calculated. The data obtained was tabulated to elucidate age-wise descriptive statistics. Quadratic polynomial regression was employed to yield a general conclusion regarding association of TMI and BMI with MUAC of the subjects. Receiver operating characteristic (ROC) curve was plotted to check which of the two indices, BMI or TMI, has better ability to predict higher MUAC of the subjects.

Results: The ROC-area under curve (AUC) was 0.867 and 0.955 for TMI and BMI respectively.

Conclusion: BMI has better association with MUAC. In comparison to TMI, BMI has superior ability in predicting higher MUAC of the subjects.
