Sucking baby's dummy clean lowers child's allergic response

DummyResearch presented at the American College of Allergy, Asthma and Immunology (ACAAI) Annual Scientific Meeting suggests a link between parental sucking clean their baby's dummy (pacifier) and a lower allergic response among young children.

"We interviewed 128 mothers of infants multiple times over a period of 18 months and asked how they cleaned their child's pacifier," says allergist Dr Eliane Abou-Jaoude, ACAAI member and lead author on the study conducted by Henry Ford Health System in Detroit. "We found the children of mothers who sucked on the pacifier had lower IgE levels." IgE is a type of antibody related to allergic responses in the body. Although there are exceptions, higher IgE levels indicate a higher risk of having allergies and allergic asthma."

Of the 128 mothers completing multiple interviews, 58% reported current pacifier use by their child. Of those who had a child using a pacifier, 41% reported cleaning by sterilisation, 72% reported hand washing the pacifier, and 12% reported parental pacifier sucking.

"We found that parental pacifier sucking was linked to suppressed IgE levels beginning around 10 months, and continued through 18 months," says allergist Dr Edward Zoratti, ACAAI member and co-author of the study. "Further research is needed, but we believe the effect may be due to the transfer of health-promoting microbes from the parent's mouth. It is unclear whether the lower IgE production seen among these children continues into later years."

"We know that exposure to certain microorganisms early in life stimulates development of the immune system and may protect against allergic diseases later," says Abou-Jaoude. "Parental pacifier sucking may be an example of a way parents may transfer healthy microorganisms to their young children. Our study indicates an association between parents who suck on their child's pacifier and children with lower IgE levels but does not necessarily mean that pacifier sucking causes lower IgE."
