We talked last week about a new report on preterm births -- the leading cause of death in newborn babies worldwide. Each year an estimated thirteen million babies are born too soon. More than one million of them die as a result of their prematurity. Yet experts say many early births can be prevented.

The report came from the March of Dimes and the World Health Organization. Christopher Howson is the vice president for global programs at the March of Dimes, a nonprofit group. He says there are a number of simple, low-cost interventions that can improve the chances of a full-term birth.
