A new NIEHS-supported study provides evidence that infants exposed to three types of mold during infancy have an increased risk of developing asthma during childhood. Since the molds are commonly found in buildings that have water damage, the study shows the importance of quickly cleaning up water damage and mold in homes.
The researchers studied 289 infants who were part of the Cincinnati Childhood Allergy and Air Pollution Study. They collected house dust samples when the infants were 8 months old and analyzed the samples for 36 molds, endotoxin, house dust mite, cat, dog, and cockroach allergens. The researchers found that 25 percent of children whose parents had allergies were asthmatic by age 7 and that exposure to Aspergillus ochraceus, Aspergillus unguis, and Penicillium variabile was linked to asthma development in the high-risk study population.
