Arterial stiffness, lipoprotein particle size, and lipoprotein particle concentration in children with type 1 diabetes.

Objective: To determine if lipoprotein particle abnormalities correlate with arterial stiffness in children with type 1 diabetes (T1D).

Study Design: In this case-control study, we evaluated 70 children, 35 with T1D and 35 controls, ages 10-18 years, matched for age, sex, race, and BMI. Arterial stiffness was assessed by radial tonometry (AI75) and blood was collected for lipoprotein subclass analysis.
