The bonds that tie a mother to her newborn may be stronger in women who deliver naturally than in those who deliver by cesarean section, according to a study published by Yale School of Medicine researchers in the October issue of Journal of Child Psychology and Psychiatry.

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.

Cesarean sections account for nearly all of the increase in U.S. singleton preterm births, according to an analysis of nine years of national birth data.

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.
