Decrease in air pollution associated with decrease in respiratory symptoms among children

Green Car Congress

The study involved children (age range, 5-18 years) from 3 groups, and was conducted during the 1993-2001, 1996-2004, and 2003-2012 years in 8 Southern California communities. While the study design does not establish causality, the findings support potential benefit of air pollution reduction on asthma control. Kiros Berhane, Ph.D.,
