Study: Fungi and Pollen Exposure and Risk of Early Childhood Wheezing

In a study published in the February 24th on-line edition of the journal Thorax, researchers examined whether birth during seasons of high fungi or pollen concentrations is associated with risk of early wheezing. Over 500 children were enrolled before birth and followed to 24 months of age, early wheezing was determined from medical records. The results showed that births in the fall-winter (the fungal spore season) were associated with early wheezing. Increased concentrations of pollen exposure during the first three months of life were also associated with increased odds of wheeze. The authors concluded that children with higher exposure to fungal spores and pollen in the first three months of life were at increased risk of early wheezing.
