In the research vitamin D levels were measured in 678 mothers in the later stages of pregnancy.
When the children were four years old, grip strength and muscle mass were measured. Results showed 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 researcher Dr Nicholas Harvey, Senior Lecturer at the Medical Research Council Lifecourse Epidemiology Unit (MRC LEU) at the University of Southampton said that 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.
