Wood Fires Can Harm the Youngest Lungs

FRIDAY, Nov. 6 (HealthDay News) -- That picturesque wood-burning stove ranks alongside auto traffic as a risk factor for bronchiolitis, the respiratory condition that is the leading cause of hospitalization in the first year of life, a new study finds.

"Those infants who had more exposure to wood-burning appliances were more likely to show up in doctors' offices or be hospitalized for bronchiolitis," said Dr. Catherine Karr, an assistant professor of pediatrics at the University of Washington, and lead author of a report in the Nov. 15 issue of the American Journal of Respiratory and Critical Care Medicine.

There hasn't been much research done on the effects of air pollution on very young children, Karr said. Such studies have typically focused on older children, in whom asthma is a more prevalent problem related to air pollution.

Karr and Canadian researchers analyzed nearly 12,000 cases of infant bronchiolitis between 1999 and 2002 in the province of British Columbia, checking on exposure to air pollutants such as nitric oxide, nitrogen dioxide, carbon monoxide and particulate matter. They also looked at the source of those pollutants.
