Obesity affects kids vitamin intake
Mothers carrying more weight pass less vitamin D on to their babies than slimmer mums, an American study has suggested.
Published in the Journal of Clinical Endocrinology and Metabolism , the research found that at the end of their pregnancies, both sets of mothers had similar levels of vitamin D in their blood. But the babies of slim mothers had a third more of the fat-soluble vitamin than those born to obese women.
Low levels of the vitamin in adults have been linked to an increase in autoimmune diseases, obesity and inflammations. It is not known what health risks babies born with vitamin D insufficiencies may face.
The study's lead author Jami L Josefson MD, assistant professor of paediatrics at Northwestern University Feinberg School of Medicine, said almost all the mothers taking part in the study had taken prenatal vitamins, which could explain why their own vitamin D levels were "sufficient".
Josefson, who is also an attending physician at Ann & Robert H Lurie Children's Hospital of Chicago, added: "It's possible that vitamin D may get sequestered in excess fat and not transferred sufficiently from an obese pregnant woman to her baby."
The study was conducted as part of a longer-term investigation of whether body fat levels at birth can predict body fat in later childhood and on into adulthood.
