The objective of this systematic review was to evaluate the association between serum 25-hydroxyvitamin D (25OHD) and cardiometabolic risk in children and the effect of vitamin D supplementation on risk.

We included 35 clinical trials, cross-sectional studies, case-control studies, and cohort studies that evaluated the relationship between 25OHD and

  • blood pressure,
  • lipid levels,
  • insulin/glucose metabolism,
  • endothelial dysfunction, and
  • arterial stiffness.

One randomized clinical trial that randomized adolescents to 2000 or 400 IU/d of vitamin D and found improvement in arterial stiffness in the high-dose group and worsening in the low-dose group.

One cross-sectional study found no relationship between 25OHD and endothelial dysfunction.

Of 12 cross-sectional studies,

  • 10 found an inverse association between 25OHD and systolic blood pressure, although
  • 2 trials found no relationship.

There was no consistent association between 25OHD and lipid levels or insulin/glucose metabolism. Insufficient evidence was available to conclude that vitamin D supplementation yields cardiometabolic benefit.
