Traffic pollution tied to childhood asthma

Asthma is one of the most common conditions children are faced with - the disease affects more than 7 million youths to date, according to the American Lung Association. There are many causes behind asthma, ranging from secondhand smoke to allergies, though a new study has found that road traffic pollution may also be partly to blame.

Scientists from the Swiss Tropical and Public Health Institute came to this conclusion after reviewing the population-attributable fractions to assess' childhood asthma rates in 10 European countries. Population-attributable fractions refer to the risk of a child developing asthma based on how close he or she lives to busy roads and high-traffic areas.

From the data it was discovered that 14 percent of asthma cases found were "due to exposure to traffic pollution near busy roads." This means air pollution could have a similar role in childhood asthma as secondhand smoke. The latter is linked to between 4 and 18 percent of all child asthma cases, according to the study.

Parents may not be able to control where they live, but they can ensure their children are breathing in the cleanest air possible at home by installing a professional-grade air purifier like the Airgle PurePal Plus AG850.
