You'd think the health-care establishment would have bigger fish to fry than Ricki Lake. (The 47 million uninsured, maybe?) But Lake's recent documentary, “The Business of Being Born,” which includes footage of her own delivery of her second child at home, was on the agenda at the American Medical Association's annual meeting in mid-June. Lake was personally name-checked in one part of a “Resolution on Home Deliveries” introduced by the American College of Obstetricians and Gynecologists: “Whereas, there has been much attention in the media by celebrities having home deliveries, with recent ‘Today Show' headings such as ‘Ricki Lake takes on baby birthing industry' ... ” The AMA ultimately passed the resolution without the Lake citation, but not before the Hollywood media got wind of it and home birth was thrust into the mainstream light.

It's about time.

Last year, I flew to Britain to be with a good friend for the birth of her first child. She's American but married into Britain's National Health Service, lucky duck. The differences in the prenatal care she got there were striking. First and foremost, she never saw a doctor. As a healthy woman with a normal pregnancy, she saw midwives. And one of their first questions to her was, “So, would you like to give birth in the hospital maternity ward or at home?”

Planning a home birth with a midwife may sound old-fashioned but a solid body of research shows that for healthy women who seek a normal, nonsurgical birth, there are several benefits. At home, a woman can get one-on-one care and monitoring from a midwife trained to support the normal labor process. The mother-to-be is free to move about, eat and drink, sit in a birth tub - Britain's national health guidelines call water the safest, most effective form of pain relief. A woman will be helped to give birth in positions that are effective and protective: sitting, squatting, on hands and knees, even standing.

The physiological birth process is automatic: hormones fire, the cervix gradually opens, the uterus contracts, the baby descends, muscles engage. An optimal birth, one in which mother and child emerge as healthy as can be, is one that begins spontaneously, progresses on its own and concludes with the least amount of intervention necessary.

But hospital maternity care in the United States is typically not supportive of this process. More than half of women are induced into labor, or it is sped up with artificial hormones; the vast majority of women labor and push in the desultory flat-on-the-back or leaning-back position; and nearly one-third of women end up giving birth through major surgery, the caesarean section.

This has led to an epidemic of pre-term births in the United States. A 2006 survey showed that the majority of babies are now born before the spontaneous onset of labor, which leaves them more prone to breathing and feeding difficulties. Caesareans are also contributing to a rising maternal death rate, announced by the Centers for Disease Control and Prevention last year.

Which is why some women, such as those in the film Lake produced, choose to give birth somewhere other than a hospital. Their choice is backed by sound science. Studies of “low-risk” women in North America planning out-of-hospital births with midwives have found that 95 percent give birth vaginally with hardly any medical intervention. The largest and most rigorous study to date published in the British Medical Journal, found that in North America, babies were born at home just as safely as in the hospital.

Organized medicine can't believe this. Dismissing the research evidence, the AMA resolution states that “the safest setting for labor, delivery and the immediate postpartum period is in the hospital” or an accredited birth center. In its own statement earlier this year, the American College of Ob/Gyns went even further, implying that women who choose home birth are selfish and irresponsible: “Choosing to deliver a baby at home ... is to place the process of giving birth over the goal of having a healthy baby.”

Compare that to this information in Britain's NHS-issued handout my friend was given at her first prenatal appointment: “There is no evidence to support the common assertion that home birth is a less safe option for women experiencing uncomplicated pregnancies.” If these groups were truly making maternal and child health a priority, they'd be reforming standard maternity care, not strong-arming women into it.
