Unborn babies exposed to urban air pollution at higher risk of vitamin D deficiency?

13 September 2012

Gestational exposure to urban air pollution has been linked to a vitamin D deficiency in newborn babies, it has been revealed.

Research published in the Journal of Clinical Endocrinology and Metabolism revealed that if unborn babies are exposed to ambient urban air pollution, particularly during the late stages of pregnancy, they may be at a higher risk of lacking vitamin D.

Study authors point out that a vitamin D deficiency in newborn babies could heighten the chance of the baby developing diseases in later life.

Recent data also showed that the maternal vitamin D deficiency during pregnancy may have an influence on the development of asthma and allergic conditions in children.

Exposure to high levels of air pollution has been suggested as a contributor to vitamin D deficiency in adults and children.

Study leader Nour Baiz, from the Intitut National de la Santé et de la Recherche Médicale (INSERM), said: "Our findings show for the first time, that exposure to ambient air pollution comparable to current World Health Organization standards might contribute to vitamin D deficiency in newborns."
