Greater aortic stiffness is associated with renal dysfunction in participants of the ELSA-Brasil cohort with and without hypertension and diabetes.

Background: Arterial stiffness has been associated with renal dysfunction and its progression, but the pathophysiological relation underlying this association has not been fully established, particularly among individuals without hypertension and diabetes. We investigated the cross-sectional associations between arterial stiffness and renal function in adults without cardiovascular disease, and whether this association remained among subjects without hypertension and diabetes.

Methods: All eligible participants from ELSA-Brasil (2008-2010), aged 35 to 74 years (N = 13,586) were included, of whom 7,979 were free from hypertension and diabetes.
