Mum’s vit D and kids’ bones

The UK study involved monitoring 25(OH)D concentration in 3960 women throughout pregnancy. Some 28% of mothers had insufficient vitamin D levels, which were defined as 27.5nmol/L — 49.9nmol/L. Vitamin D deficiency was found in 6% of mothers whose levels were below 27.5nmol/L. Their children’s bone-mineral content (BMC) was assessed at a mean of 9.9 years using dual-energy x-ray absorptiometry.

The authors said there was no strong evidence that pregnant women should receive vitamin D supplementation to prevent low BMC in their offspring.
