Awareness and treatment of dyslipidemia in young adults with type 1 diabetes.

OBJECTIVE Dyslipidemia is a preventable major risk factor for coronary heart disease (CHD). Despite an increased risk of CHD in type 1 diabetes, little is known concerning awareness and adequacy of dyslipidemia treatment in this population. In this report, we describe the prevalence of dyslipidemia and adequacy of pharmacological treatment in patients with type 1 diabetes and comparable nondiabetic subjects. RESEARCH DESIGN AND METHODS From 2000 to 2002, the Coronary Artery Calcification in Type 1 Diabetes study obtained fasting lipid profiles in 1,416 individuals aged 19-56 years with no history of CHD: 652 type 1 diabetic patients (46% men, mean age 37 +/- 9 years) and 764 nondiabetic control subjects (50% men, mean age 39 +/- 9 years). These data combined with patient questionnaire results were used to determine prevalence of dyslipidemia and adequacy of pharmacological treatment. For all subjects, dyslipidemia was defined using National Cholesterol Education Program Adult Treatment Panel III criteria. RESULTS Type 1 diabetic subjects had significantly less dyslipidemia than nondiabetic control subjects (47 vs. 58%, P < 0.001), and a higher percentage of those with abnormal lipids were aware of (52 vs. 34%, P < 0.0001), on medication for (36 vs. 9%, P < 0.0001), and in control of their lipid levels (15 vs. 1.4%, P < 0.001). Of those on treatment, control was achieved in 41% of type 1 diabetic subjects and 15% of nondiabetic participants (P < 0.01). CONCLUSIONS Dyslipidemia, a major risk factor for CHD, remains largely undiagnosed and undertreated in high-risk populations, such as patients with type 1 diabetes.
