Researchers presented the latest research on the relationship between maternal nutrition and stress with the occurrence of asthma in children, the annual meeting of the American Academy of Allergy, Asthma and Immunology in Miami in early March 2006 yesterday.
The findings explain that the mothers who are pregnant when routine vitamin D will reduce the risk of asthma in children at birth. Vitamin D deficiency can cause symptoms of asthma, even expected to increase two-fold compared with those without vitamin D deficiency, said Dr. Carlos Camargo, a senior researcher and a professor in the field of medicine and epidemiology at Harvard Medical School, Boston. Camargo and his team monitor the mother and child pairs for more than three years.
At 2-year-old child, would seem clear relationship between high intake of vitamin D when the mother is pregnant with a lower risk of wheezing and asthma in children, he said in his presentation. The results previously mentioned, that the deficiency of vitamin D has implications for the development of fetal immune system. Camargo said the source of vitamin D can be obtained from eating habits like consumption of milk, fish and various supplements.
The experts from Canada found that pregnant women who suffer from asthma appear to be greater obtain babies born premature and low weight babies (LBW). In addition, the survey of 13,980 children born in Manitoba found that mothers suffering from asthma, the average between 2.78 times higher as many have babies born less than 28 weeks gestation and 3.04 times more likely to have babies born less than 32 weeks of gestation when compared with pregnant women without asthma.
Other research groups from the same university found that children whose mothers suffer laihr of stress (depression or anxiety) had 1.3 times as many suffering from asthma. The risk will be even higher if the mother suffered a repetitive stress, said Anita Kozyrskyj, lead researcher and professor in the field of pharmacy.
