Determinants of Arterial Stiffness and Vascular Aging in the Older Adult

Abstract Background: Arterial stiffness (AS) is recognized as an important and independent risk factor for cardiovascular diseases (CVD). Objective: This study was aimed at identifying the main determinants of AS in the elderly. Design and Methods: This was an observational, cross-sectional study of elderly participants. Blood pressure (BP) and parameters of arterial function were measured using a validated device. Clinical and demographic data, global cardiovascular risk, health-related quality of life, dietary profile and cognition data were evaluated. Blood samples were collected for biochemical profiling of the participants. Handgrip strength test was performed. Student's t-test and the χ2 or Fisher exact tests were used for between-group comparisons as adequate. Correlational analysis was performed with the Pearson correlation coefficients and linear regression analysis. A two-tailed p
