Reason Why First-Born Kids Face Higher Asthma, Allergy


Washington (ChattahBox) - A new study has discovered why first-born children face a higher risk of developing asthma and allergies, and it has a lot to do with factors during pregnancy.

Researchers analyzed over 1,200 kids in the UK and found that the increased risk was due to a chemical in the umbilical cord blood, an antibody called lgE.

The antibody lgE is associated with the immune system, putting kids at an increased risk of asthma and allergies. The level of lgE is lower after the first-born.
It was noted that the increased risk of asthma and allergies for these first-born children persist through their childhood

The study has been presented at the American Thoracic Society’s annual conference in Toronto
