Vitamin D during pregnancy impacts on Children’s muscle mass.

from the Medical Council Lifecourse Epidemiology Unit (MRC LEU) at the University of Southhampton, published in the Journal of Clinical Endocrinology and Metabolism, has specified that children are more likely to have a higher muscle mass if their mothers had a higher level of vitamin D during .

Prior studies have demonstrated that low vitamin D has been linked to reduced muscle strength in adults and children but this is the first study to confirm the demonstrated impact of Vitamin D during .

The study pool consisted for 678 mothers in the later stages of . Children were tested at the age of four for grip strength and muscle mass. The findings reflected that the higher the levels of vitamin D in the mother, the higher the grip strength of the child, with an additional, but less pronounced association between mother’s vitamin D and child’s muscle mass.

Lead Dr Nicholas Harvey, Senior Lecturer at the MRC LEU at the , stated: “These associations between maternal vitamin D and offspring muscle strength may well have consequences for later health; muscle strength peaks in young adulthood before declining in older age and low grip strength in adulthood has been associated with poor health outcomes including diabetes, falls and fractures. It is likely that the greater muscle strength observed at four years of age in children born to mothers with higher vitamin D levels will track into adulthood, and so potentially help to reduce the burden of illness associated with loss of muscle mass in old age.”
