Stillbirth may seem to be rare, but it actually occurs in about 1 of every 160 pregnancies. Of these stillbirths, 10 to 20 percent occur during labor and delivery. But U.S. doctors can offer pregnant women little help in assessing their risk for stillbirth and even less help in preventing it. Ruth Fretts, assistant clinical professor of obstetrics, gynecology and reproductive biology at Brigham and Women’s Hospital, is quoted.
