59-OR: Lipoprotein Particle Distribution by NMR in Youth with Type 2 Diabetes (T2D) in the TODAY Study

T2D in adolescents is associated with an unfavorable lipid profile, but data on lipoprotein particle size and distribution in this population have yet to be published. The TODAY Study, a randomized treatment trial of T2D in youth, provided the opportunity to evaluate lipoprotein particle distribution and relate lipoprotein particle number and size to HbA1C, need for insulin treatment, gender, race/ethnicity, BMI, and blood pressure (BP). TODAY participants (n=348) with yearly samples available for NMR Lipoprofile assessments (baseline, 12, 24, 36 mos) were included. Baseline participant characteristics (mean±SD) were: age 13.7±2.0 yrs; BMI 34.3±7.6 kg/m2; 62.4% female; 20.7% White, 32.2% Non-Hispanic Black (NHB), 43.7% Hispanic. Analysis demonstrated increasing numbers of LDL, HDL, and VLDL particles over the three yrs (all ps In conclusion, these data demonstrate an atherogenic lipoprotein phenotype in youth with T2D and strong relationships with glycemic control and other cardiac risk factors. Concern regarding premature development of atherosclerosis in youth with T2D is warranted. Disclosure L.E. Katz: None. J.D. Otvos: Employee; Self; LabCorp. K. Drews: None. B. Tesfaldet: None. F.
