IL6 and Abdominal obesity: Actually, the mechanisms underlying arterial stiffening remain to be elucidated, but the fact that changes in ba-PWV between the baseline and 3-year follow-up data were positively correlated with the changes in WHR, ox-LDLs, MDA, hs-CRP, and IL-6 levels suggest that changes in oxidative stress, proinflammation, or abdominal obesity could play an important role, in part, in accelerating arterial stiffness.
