Obesity is associated with increased arterial stiffness from adolescence until old age

Across a wide age range, the diameter and stiffness of muscular arteries increased with higher BMI. In elastic arteries, the relationship between arterial stiffness and BMI was more complex and varied with sex and age. The mechanisms underlying the influence of adiposity on the properties of muscular and elastic arteries and the reversibility of these associations by weight reduction at young age need further clarification.
