Oregon has low premature birth rate
Oregon has the lowest rate of premature births in the region -- 10.3 percent -- and that gives it the third lowest rate in the nation after Vermont and New Hampshire, according to the March of Dimes 2009 Premature Birth Report Card, which was released late Monday.
The number of premature births in this country has risen 20 percent in the last 20 years and doctors don't know why.
