Obese children more susceptible to asthma from air pollution
Date:1/22/2014

children could result in more time spent indoors, thereby increasing exposure to indoor PAH. Another may have to do with more rapid breathing in those who are obese.

Better understanding of the risk factors opens the door to more targeted interventions. "These findings suggest that we may be able to bring down childhood asthma rates by curbing indoor, as well as outdoor, air pollution and by implementing age-appropriate diet and exercise programs," says senior author Rachel Miller, MD, Professor of Medicine (in Pediatrics) and Environmental Health Sciences, chief of Pediatric Allergy and Immunology at CUMC, and co-deputy director of the Columbia Center for Children's Environmental Health at Columbia's Mailman School of Public Health.

The study builds on earlier research findings that linked increased asthma risk with exposure to higher levels of air pollution. Drs. Jung and Miller previously had shown an association between repeated high prenatal and childhood PAH exposure and asthma. A number of studies also have found an association between obesity and asthma.
