"This is a major public health concern," Barr tells WebMD.
"Given the widespread use of acetaminophen and ibuprofen among kids -- and asthma being the disease of
greatest burden in kids -- this would seem to be an important topic for further
Barr notes that previous studies have linked acetaminophen, but not
ibuprofen, to asthma and have linked use of
acetaminophen during pregnancy to childhood asthma.
Barr's own research team previously found that high-level acetaminophen use
raised women's risk of adult-onset asthma.
"There is still a lot of uncertainty about this," he says.
"There might be something going on, but do we have a clear public health
recommendation at this time? I don't think we do."
Childhood Lung Problems Increase Adult Asthma
Underscoring the importance of early-childhood events for later asthma is a
study from the University of Arizona, Tucson.
Fernando D. Martinez, MD, director of the Arizona Respiratory Center at the
University of Arizona, and colleagues followed 849 children from birth to age
Those with adult
- 7.4 times more likely to have had childhood asthma
- 14 times more likely to have had persistent wheezing as children
- 3.6 times more likely to have had a childhood mold allergy
- Twice as likely to have had low airway function at age 6
More than 70% of the adults who had adult asthma were women.
"We conclude that asthma that apparently develops early in adult life
affects mainly women and is commonly the clinical expression of latent changes
of airway responses that are present in the preschool years," the
The Beasley and Martinez studies, and Barr's editorial, appear in the Sept.
