Vitamin E link to early asthma
Posted: Sat 02/09/2006

Children are more likely to develop asthma and wheezing by the age of five if their mothers consumed low levels of vitamin E during pregnancy, the results of a new study indicate.

A team of researchers at the University of Aberdeen followed the progress of 1,253 mothers and children over a five-year period.

They found that children whose mothers had consumed the lowest levels of vitamin E during pregnancy were over five times more likely to have early persistent asthma, compared to children whose mothers had consumed the highest levels of the vitamin. Good sources of vitamin E include vegetable oils, such as sunflower oil, margarine, wheat germ, nuts and sunflower seeds.

According to Dr Graham Devereux of the university, the findings suggest that vitamin E has important effects on lung function and airway inflammation. However the team noted that as the airways are fully developed 16 weeks after conception, vitamin E exposure in early pregnancy may be more likely to influence airway function than exposure later in pregnancy.

In an earlier study of the same children, the researchers found that when they were two years old, they were more likely to wheeze if their mother’s vitamin E intake during pregnancy had been relatively low.

“The results of the present study suggest that dietary modification or supplementation during pregnancy to reduce the likelihood of childhood asthma warrants further investigation”, Dr Devereux said.

The team added that vitamin E supplementation in adults with established asthma has been shown to be of no clinical benefit.

Details of these findings are published in the American Journal of Respiratory and Critical Care Medicine.
