March of Dimes rates U.S., cities, states on preterm births

The March of Dimes released its eight annual report card rating cities, states, and the United States as a whole on the percentage of preterm births. The US received a “C” rating with a 9.6 percent preterm birth rate while the states received ratings ranging from “A” to “F.”

“The good news is the rates are coming down in the U.S., which I think is very encouraging. There have been fewer teen pregnancies and we are reducing preterm birth in women who’ve had previous preterm births,” says Dr. Louis Muglia, co-director of the Perinatal Institute and director of the Center for Prevention of Preterm Birth.
