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.
Metabolic syndrome is also known as
metabolic syndrome X,
insulin resistance syndrome,
Reaven's syndrome (named for Gerald Reaven), and
CHAOS (in Australia)
