During labor, the continued presence of a doula – an experienced non-medical female companion who provides continuous labor support – has significant beneficial effects for middle- and upper-class women in childbirth, even when they have their male partner or other family member with them, according to a new study in the journal Birth.

The percentage of United States cesarean births increased from 20.7% in 1996 to 31.1% in 2006. Cesarean rates increased for women of all ages, race/ethnic groups, and gestational ages and in all states.

At a time when national rates of cesarean delivery have climbed above 30%, a four-year study of patients receiving an alternative method of obstetric care experienced a significantly lower rate of cesarean births, according to a study published in the current issue of the Annals of Family Medicine.
