OBJECTIVE -- This study investigated the association between arterial stiffness and plasma adiponectin in patients with type 1 diabetes. RESEARCH DESIGN AND METHODS -- Participants were normotensive patients with type 1 diabetes who were up to age 40 years. Subjects on statins with macrovascular disease or overt nephropathy were excluded. Large artery stiffness was assessed by measurement of carotid-femoral pulse wave velocity (PWV), whereas plasma adiponectin was measured by radioimmunoassay. RESULTS -- Data from 80 patients (age 27.1 ± 6.1 years, BMI 24.2 ± 3.1 kg/m², HbA1c 7.5 ± 1.6%, 39 men, adiponectin 13.9 ± 6.7 μg/mL, and PWV 5.6 ± 0.9 m/s) were analyzed. Log adiponectin inversely correlated with age-adjusted PWV (r = -0.291, P = 0.009) and waist circumference (r = -0.427, P < 0.001). In a fully adjusted model, age, expiration/inspiration index, and log adiponectin were independently associated with PWV, explaining 39.6% of its variance. CONCLUSIONS -- Arterial stiffness is inversely related to adiponectin concentration in young patients with type 1 diabetes without major complications.
