Day care attendance early in life seems to protect infants and young children from later developing asthma, according to new research.
Janet Rothers, MS, and colleagues examined the relationship between the age at which day care attendance begins and the amount of immunoglobulin E (IgE) in a child’s blood. IgE is an antibody produced by the immune system and an indicator of allergic sensitivity.
The authors speculate that regular exposure to bacteria from two different environments may play a role in immune development and supports the idea that there may be a critically short period when such bacterial exposure can guide the immature immune system to develop on a healthy path.
The study, “Influence of early day care exposure on total IgE levels through age 3 years” can be found in the Articles in Press section of the JACI Web site. The JACI is the peer-reviewed journal of the American Academy of Allergy, Asthma & Immunology.
