OBJECTIVE -The aim of this data analysis was to ascertain the type and prevalence rate as well as age and sex distribution of cardiovascular risk factors in type 1 diabetic patients up to 26 years of age.RESEARCH DESIGN AND METHODS -Cardiovascular risk factors such as obesity, hypertension, dyslipidemia, poor glycemic control, and smoking were analyzed in 27,358 patients who were divided into three groups (prepubertal, pubertal, and adult) using specifically designed diabetes software for prospective disease documentation.RESULTS -More than half of the patients per age-group had at least one cardiovascular risk factor. Two risk factors were age dependently found in 6.2-21.7% and three or four risk factors in 0.5-4.7%. Elevated values of HbA 1c , total cholesterol, and BMI were found most frequently. Hypertension, smoking, and HDL cholesterol were observed more frequently in males, and elevated BMI, total cholesterol, and LDL cholesterol more often in females. Although 28.6% of the patients had dyslipidemia, merely 0.4% of them received medical treatment, and of the 8.1% of the patients with hypertension, only 2.1% of them were given antihypertensive medication.CONCLUSIONS -With increasing age, a greater number of patients with cardiovascular risk factors were observed. Significant sex differences were seen in the majority of risk factors. Despite the high prevalence of risk factors, only a small minority of patients received antihypertensive or lipid-lowering treatment. Early identification, prevention, and treatment of additional risk factors seem to be necessary, particularly in light of the high incidence of future cardiovascular disease.
Diabetes Care 29:218 -225, 2006T ype 1 diabetes is increasingly recognized as an independent risk factor for premature cardiovascular disease (CVD) and elevated cardiovascular death rate in patients aged 20 -39 years (1). Postmortem studies in children and youth who had died an unnatural death also showed that the development of atherosclerotic lesions of the vessel wall starts in childhood and that there is a close relationship to cardiovascular risk factors. In the Bogalusa Heart Study (2) and the Pathobiological Determinants of Atherosclerosis in Youth (PDAY) study (3), the evaluation of premortal existing risk factors (glycohemoglobin Ͼ8%, increased lipids, hypertension, obesity, and smoking) verified their unfavorable influence on the progression of atherosclerosis. Because childhood and adolescence diabetes is commonly associated with additional risk factors (4,5), we conducted this analysis to obtain reliable data about character and prevalence rate as well as age and sex differences of potential atherogenic risk factors in a large population of German children, adolescents, and young adults with type 1 diabetes.
RESEARCH DESIGN ANDMETHODS -Based on the continuous diabetes data acquisition system for prospective surveillance (DPV), a crosssectional analysis was carried out to evaluate associated cardiovascular risk factors in patients with type 1 diabetes. The data do...
