Maybe You Can Keep Your Pet Even if You Have Asthma

A study from Nationwide Children's Hospital in Columbus, Ohio, suggests that environmental exposure to pets or secondhand smoke is not a significant factor in asthma improvement over time, once asthma treatment guidelines are implemented. Results of this study, published in Chest, are being presented at the CHEST Annual Meeting 2018 in San Antonio, Texas.

The study involved 395 children 2 to 17 with uncontrolled asthma who were provided asthma care according to guidelines from the National Asthma Education and Prevention Program. About 55 percent of study participants were exposed to a dog or cat at home and 25 percent were exposed to secondhand smoke.

At three- and six-month follow-ups, asthma control was evaluated, and the families completed comprehensive asthma questionnaires. The researchers compared results between patients with or without exposure to secondhand smoke and with or without exposure to a pet at home at baseline and over time and observed improvement in asthma symptoms independent of environmental exposures. This suggests asthma treatment plays a more important role in controlling symptoms than secondhand smoke or pet exposure.
