A 20-year study finds that millennial children in Southern California breathe easier than ones who came of age in the '90s, for a reason as clear as the air in Los Angeles today.

The University of Southern California Children's Health Study measured lung development between the ages of 11 and 15 and found large gains for children studied from 2007 to 2011, compared to children of the same age in the same communities from 1994-98 and 1997-2001.

The gains in lung function paralleled improving air quality in the communities studied, and across the Los Angeles basin, as policies to fight pollution took hold.

The research appears in the March 5, 2015 issue of the New England Journal of Medicine.
