Cleaner Air Is Better for Kids' Lungs

Air quality improvement was associated with growth of lung function between the ages of 11 and 15 years in children with or without asthma.

Poor air quality has been associated with childhood asthma; however, the potential benefit of improved air quality on lung development in childhood is unknown. Using data from the National Children's Study, researchers assessed 4-year changes in lung function measurements (1-second forced vital capacity [FEV₁] and forced vital capacity [FVC]) between the ages of 11 and 15 years in 1585 children followed during 3 periods in which air pollution reduction efforts were underway (1994–1997, 1997–2001, and 2007–2011).

Air quality improved in all five communities during the study periods. Large declines occurred in levels of particulate matter <2.5 µm and <10 µm (PM_2.5 and PM₁₀) and nitrogen dioxide. Less improvement was observed in ozone level. Th…
