Pregnancy stress can affect child's health

New research indicates stress could predispose babies to allergies and asthma. Those findings were revealed over the weekend at a conference in Canada.

The researchers from Harvard say in their studies mothers who were the most distressed during pregnancy were the most likely to give birth to infants with higher levels of protein linked to allergies.

Previous studies on animals had suggested that a combination of stress and allergy triggers, like dust mites, during pregnancy can affect an offspring's immune system.
