Links between parents’ and children’s asthma and allergies

New research found that, compared with a father’s traits related to allergies and asthma, a mother’s traits create a higher risk that a child will develop these same traits in early childhood. By the time the children were 6 years old, however, both parents presented the same risk. This suggests that non-genetic factors related to mothers—such as factors present in the uterus during pregnancy—may confer an added risk of allergies and asthma to children.

The Clinical & Experimental Allergy study included 685 parent-child trios.
