Vitamin D supplementation during pregnancy and offspring bone microarchitecture: A post hoc analysis of the MAVIDOS randomised controlled trial.

What Was Tested

The paper reports a study of Vitamin D, K2, Magnesium and Zinc, published as a randomized controlled trial.

The effect of this intervention on bone microarchitecture, a further determinant of bone strength, and possible interactions with genetic variation in vitamin D metabolism, have not previously been investigated.

The researchers investigated these in a post hoc analysis of a randomised controlled trial.

Who Took Part

The age groups tagged for this paper are children, both men and women.

Maternal and child genotype at four single nucleotide polymorphisms (SNPs) [rs12785878 (DHCR7), rs10741657 (CYP2R1), rs6013897 (CYP24A1), rs2282679 (GC)] was determined using serum samples.

How the Study Was Run

In design terms this was a randomized and placebo-controlled study.

Because people in this Vitamin D, K2, Magnesium and Zinc study were split into groups at random, differences between the groups are less likely to reflect who happened to join each one.

The comparison arm used a placebo, so changes seen with Vitamin D, K2, Magnesium and Zinc could be set against what happens without it.

Offspring tibial bone microarchitecture was assessed at age 6-7 years using high resolution peripheral quantitative computed tomography (HR-pQCT; Stratec Xtreme CTII).

Differences in bone microarchitecture by randomisation were assessed using linear regression, and additionally across clusters of bone microarchitecture phenotypes generated using cluster analysis approaches.

What Was Measured

The subject headings attached to it are Dietary Supplements, Vitamin D, Bone Density, Polymorphism, Single Nucleotide, Bone and Bones and Cholecalciferol.

Author keywords: Bone microarchitecture, Bone mineral density, High resolution peripheral quantitative computed tomography (HR-pQCT) and pregnancy.
