A U.S. study finds babies born by Caesarean section are nearly three times more likely to die during the first month of life than those born naturally.
The research by the Centers for Disease Control and Prevention in Atlanta is said to be the first to examine death rates of babies born by elective Caesarean or when there's no medical need for the procedure.
Study leader Marian MacDorman of the CDC said: "Neonatal deaths are rare for low-risk women -- of the order of one death per 1,000 live births. But even after we adjusted for socioeconomic and medical risk factors, the difference persisted."
The study involved more than 5.7 million U.S. births and 12,000 deaths occurring within 28 days of birth from 1998-2001.
In women defined as low-risk, the average rate of neonatal death was 0.62 per 1,000 vaginal births. In Caesarean births, low-risk mothers were nearly three times more likely to lose their child, at a rate of 1.77 per 1,000 births.
The research appears in the journal Birth: Issues in Perinatal Care.

C-sections a critical factor in preterm birth increase
May 28th, 2008
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.
Between 1996 and 2004 there was an increase of nearly 60,000 singleton preterm births and 92 percent of those infants were delivered by a cesarean section, (c-section), according to research by investigators from the March of Dimes and the U.S. Centers for Disease Control and Prevention (CDC) that will be published in the June issue of Clinics in Perinatology.
While singleton preterm births increased by about 10 percent during this time, the c-section rate for this group increased by 36 percent.
Preterm birth is a serious and costly health concern and is the leading cause of death in the first month of life. More than 520,000 babies – one out of every eight – are born too soon each year in the United States.
Late preterm babies, those born 34-36 weeks gestation, account for most of the increase in the US singleton preterm birth rate. These infants have a greater risk of breathing problems, feeding difficulties, temperature instability (hypothermia), jaundice, delayed brain development and death than babies born at term. This new analysis shows that that these late preterm infants had the largest increase in c-section deliveries.
“While maternal and fetal complications during pregnancy may result in the need for a c-section, we’re concerned that some early c-section deliveries may be occurring for non-medically indicated reasons,” said Alan R. Fleischman, M.D., the March of Dimes medical director and senior vice president. “We need research to determine how many c-sections that result in preterm babies are not medically indicated and may place both mother and baby at risk for little or no medical benefit. ”
C-sections are the most common major surgical procedure for women. More than 30 percent of the 4.1 million U.S. live births are delivered via c-section and the rate has increased dramatically since 1996. A c-section delivery can be lifesaving when there are complications during pregnancy, but it is a major operation with potential risks to the mother from the surgery and anesthesia and to the baby, if the delivery occurs too soon. The March of Dimes is concerned that some early deliveries may occur without good medical justification and may be done at the request of the mother or based on an inappropriate recommendation from the doctor.
