TUCSON, Ariz. (AP) — Researchers at the University of Arizona will be launching a study of how prone Hispanic children are to asthma in Tucson compared with their peers on the other side of the U.S.-Mexico border in Nogales, Sonora.

The study will follow 500 pregnant women of Mexican descent in both cities and their newborns for the next five years to see how prevalent asthma is.
