Arterial stiffness is influenced by advancing age and vascular disease and is an independent risk factor for cardiovascular events and death. Using ultrasound measurements, arterial stiffness in a specific arterial segment can be assessed. The aim of this observational study was to explore the prospective and cross- sectional associations between arterial stiffness measured by ultrasound locally in the abdominal aorta and cardiovascular risk factors/markers including insulin resistance measured by the homeostatic model assessment- insulin resistance (HOMA- IR), lipids and abdominal obesity. This study includes 335 subjects from Malmo ", Sweden, examined in 1991- 1994 and again at follow- up in 1998- 2000 (mean age 64 years, 42% men). Ultrasound measurement of the abdominal aorta was performed at follow- up investigation. In the female subgroup, there was a positive association between HOMA-IR at baseline and abdominal aortic stiffness at follow-up (beta = 0.18, P 0.03) and a negative association between high-density lipoprotein and aortic stiffness (beta = 0.23, P 0.005), independently of classical cardiovascular risk factors. These associations were not found among men. The results suggest a greater or different role of impaired glucose metabolism in the pathophysiology of arterial stiffness in women than in men.
