MOTHERS who had low vitamin D levels while they were pregnant are more likely to have a child with a language impairment than mothers who had higher levels of the vitamin, an Australian study suggests.
While the study, published in Pediatrics, did not show that low levels of the vitamin itself caused the issues, researchers said it pointed to a "plausible association" that warranted more attention.
Earlier studies had shown some links between low vitamin D during pregnancy and problems in children such as weaker bones, asthma and poor growth, said Andrew Whitehouse, lead author of the study, who was based at the University of Western Australia. "The effects of lower maternal vitamin D levels on the developing offspring is not fully understood," he said.
Twenty years ago Whitehouse and his colleagues measured the vitamin D levels of more than 700 women who were about halfway through their pregnancy, seeking to determine whether levels of the vitamin might have anything to do with children's later behavioral and language development.
Five and 10 years later, they tested the children of these mothers to measure their behavioral and emotional development, and language skills.
