Objective:
To evaluate the degree of atherosclerosis and its risk factors in adolescents and young adults with type 1 diabetes.
Study Design:
We measured carotid artery intima-media thickness (IMT) in 142 subjects with type 1 diabetes (mean [SD] age = 16.0 [2.6] years) and 87 control subjects (18.8 [3.1] years). Fasting lipid and homocysteine levels, degree of glycemic control, blood pressure, and body mass index were measured in persons with diabetes.
Results:
The mean carotid IMT was greater in persons with diabetes ( P = .002). Among subjects with type 1 diabetes, lipid levels were significantly higher in female subjects compared with male subjects. The mean carotid IMT was significantly higher in persons with a diabetic complication (including hypertension, retinopathy, or microalbuminuria). In male subjects but not female subjects, HDL cholesterol and the LDL/HDL ratio were correlated with carotid IMT.
Conclusions:
Adolescents with type 1 diabetes have increased atherosclerosis compared with control subjects. Risk factors for increased carotid IMT in these younger patients include diabetic complications and HDL cholesterol and the LDL/HDL ratio, which may be sex-specific.

Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...
