Wheezing in Early Childhood Means Increased Asthma Risk for Teens

ThinkstockPhotos-182264980Children who wheeze consistently through infancy and early childhood are most likely to develop asthma by the age of 15, but babies who wheeze only intermittently are also at risk, new research indicates.

The study, recently published online in JAMA Pediatrics, involved tracking the breathing and wheezing patterns of 320 children from before birth to 7 years old, and then following up with them when they were teenagers.

The Canadian children in the study who wheezed consistently through early childhood had an 11 times higher rate of asthma risk by age 15 as compared to non-wheezers. For kids who outgrew wheezing by young childhood, the asthma risk as a teenager was still four times higher than that of non-wheezers.

The findings underscore the importance of preventive treatments, says the study’s leader author, Dr. Meghan Azad, an assistant professor in pediatrics at the University of Manitoba.

“Our research shows that asthma-associated deficits in lung function are already present at a very young age, suggesting that interventions to reduce early-life wheezing could have significant long-term health benefits,” she said.

The study also involved other U of M, University of British Columbia, and University of Alberta researchers affiliated with Canada’s AllerGen research network.
