Allergies Linked to Early Antibiotic Use
A large study from Columbia has determined that childhood allergic rhinitis – also called hay fever or simply allergies – are associated with the use of antibiotics when the child was under one year old.
The research studied 3,256 schoolchildren between six and seven years old and 3,830 school kids from 13 to 14 years old. All the children were from Bogota, Colombia.
The research followed the methods established by the International Study of Asthma and Allergies in Childhood, or ISAAC.
The research, published in this month’s Journal Rhinology, found those children who took antibiotics in the first twelve months of life were 70% more likely to have allergies.
This confirms the association presented by other research showing that probiotic populations in the oral cavity and the gut are crucial for maintaining immunity as a child. A typical course of antibiotics will decimate our natural probiotic populations.
Likely for this very same reason, children born with cesarean delivery were 60% more likely to suffer from allergic rhinitis. The cesarean section eliminates the child passing through the full birthing canal – which inoculates the baby with critical probiotic organisms from the mother.
The research also found that the risk of allergic rhinitis significantly increased in children who were using acetaminophen within the last year.
Among the study population, over 30% of the children and over 36% of the teenagers reported allergic rhinitis. This represents a dramatic increase in the condition over the past decade.
