Air Pollution Makes Controlling Asthma Difficult, Study Finds

John Foxx/Thinkstock(VILLEJUIF, France) -- Air pollution is known to increase the risk of developing asthma, but French researchers found that it also makes controlling it more difficult.  

Researchers at INSERM and CESP Centre for Research in Epidemiology and Population Health surveyed 481 people about their asthma symptoms and compared that data to information about local levels of ozone, nitrous oxide, and particulate matter -- all factors that contribute to poor air quality.  The survey results showed that levels of ozone and particulate matter were strongly linked to poorer asthma control, with long-term exposure increasing the risk of having uncontrolled asthma by 69 percent and 35 percent, respectively. 

Therefore, the authors conclude that “both ambient O3 [ozone] and PM10 [particulate matter] concentrations jeopardize asthma control in adults.”

These findings were published in the Journal of Epidemiology and Community Health.
