Comparison of Body Mass Index and Percent Body Fat on Risk Factors for Type 2 Diabetes Mellitus in Children aged 10-14
Methods: Data were obtained from 290 10-14 year olds in North Central Texas participating in a study examining risk for T2DM. A Tanita body composition analyzer was used to measure BMIP and PBF. Associations were assessed using logistic regression models against four critical risk factors for T2DM: Average blood pressure (BP) above 95th percentile or history of high BP, family history of T2DM, Acanthosis Nigricans (AN) and a high glucose test, controlled for age, gender and race.
Results: Among 290 subjects, 78.2% were Hispanic, with 13.4% Black. 51% were female, while age was evenly distributed. Logistic regression models found that both PBF and BMIP were significantly associated with AN (PBF: Sβ 0.584 p<0.01 vs. BMIP: Sβ 0.489 p<0.01), average systolic BP above 95th percentile (PBF: Sβ 0.219 p<0.01 vs. BMIP: Sβ 0.124 p<0.05), family history of T2DM (PBF: Sβ 0.189 p<0.01 vs. BMIP: Sβ 0.172 p<0.01), and high glucose (PBF: Sβ 0.152 p<0.01 vs. BMIP: Sβ 0.119 p<0.05).
Conclusions: Data from this study provide evidence that PBF may be a better measurement of T2DM risk among children compared to BMIP. It may be beneficial for physicians to measure PBF alongside BMIP to better ascertain a patient’s risk of T2DM.

Qualified on the content I am responsible for because: I am a co-investigator in the study, "Physiological and Psychosocial Predictors of Type 2 Diabetes Mellitus among children aged 10-14," conducted at the University of North Texas Health Science Center. As an assistant professor in the department of pediatrics, I have worked on several grants on type 2 diabetes and continue to advocated obesity prevention in children as I recognize diabetes to be a growing problem among our patient population.
