“…Two-thirds of these kids live in urban areas, according to the study by researchers at George Washington University in Washington, D.C. ‘Our findings suggest that millions of new cases of pediatric asthma could be prevented in cities around the world by reducing air pollution,’ said senior study author Susan Anenberg. She is an associate professor of environmental and occupational health at the university’s Milken Institute School of Public Health…” (Preidt, 4/11).

Newsweek: Air Pollution: U.S. Ranks World’s Third Worst in Study on Asthma in Children
“…The new study focused on the effects of nitrogen dioxide (NO2), a major component of traffic-related air pollution. Scientists at George Washington University Milken Institute School of Public Health studied data collected between 2010 and 2015 on 125 cities across 194 countries. They investigated factors including concentrations of NO2 in the air; populations; and rates of asthma in each country. The findings were published in the journal Lancet Planetary Health…” (Gander, 4/10).

U.S. News & World Report: Air Pollution Linked to 4M New Cases of Pediatric Asthma a Year

Among 125 cities included in the study, pollution was linked to a low of 6% of cases in Orlu, Nigeria, and a high of 48% in Shanghai. The pollutant’s contribution to new pediatric cases of asthma was more than 20% in 92 cities, including Moscow; Seoul, South Korea; and eight cities in China…” (Lardieri, 4/10).
