Low serum 25-Hydroxy (OH) vitamin D levels are associated with increased arterial stiffness in healthy children: An echocardiographic study from Turkey.

Our study results revealed a significant relationship between 25-OH vitamin D levels indicative of a deficiency and aortic stiffness. Hence, we suggest that arterial stiffness may also occur in healthy children with a 25-OH vitamin D deficiency. Future in-depth studies are needed to understand the exact mechanisms underlying the aortic stiffness development associated with 25-OH vitamin D deficiency.
