More women choose do-it-yourself births

A growing number are having babies at home without medical help

Jennifer Margulis thinks birth should be a private party — no doctors or midwives invited. So when her daughter Leone Francesca was born at home last month, only Margulis and her husband, James, were in attendance.

“My husband and I were the only ones there when she was conceived,” says the 40-year-old writer from Ashland, Ore. “I thought we should be the only ones there when she was born.”

Margulis is part of a very small but growing number of women who are choosing to deliver their babies at home without the presence of health professionals. Some choose to have a husband or another family member help, while others opt to deliver their babies completely on their own.

The number of home births unattended by either a doctor or a midwife jumped by nearly 10 percent between 2004 and 2006, climbing from 7,607 unassisted births to 8,347 births, according to most recent figures from the National Center for Health Statistics. About 60 percent of the nearly 25,000 home births logged in 2006 were attended by midwives, a figure that experts expect will also rise.

While do-it-yourself deliveries are still uncommon, many doctors and midwives consider them dangerous. Risks can range from hemorrhage in the mother to problems with the baby’s oxygen supply during delivery.

“Most births are not complicated but when something goes wrong, everything happens very quickly and things can go downhill very fast,” says Donna Strobino, a professor and deputy chair in the department of maternal and child health at the Johns Hopkins Bloomberg School of Public Health in Baltimore.

“If you look at data from developing countries where unattended births are more common, you see a higher rate of infant and maternal mortality with unattended births than with hospital births.”

Even among healthy women with no clear risk factors, life-threatening complications can arise suddenly, says Dr. Hyagriv Simhan, an associate professor of obstetrics and gynecology and chief of maternal-fetal medicine at the Magee-Womens Hospital of the University of Pittsburgh Medical Center. “There are lots of women who experience unpredictable bad events,” Simhan says.

Shauna Schoenborn, a stay-at-home mom from Imperial, Mo., and other advocates of unassisted birth aren’t swayed by doctors’ warnings. To them, pregnancy and delivery are natural processes that the medical establishment has turned into disease that must be managed.

After giving birth to her first baby in the hospital, Schoenborn, 31, chose to have her next four children at home — by herself. Although her husband was in the house during the births, he didn’t help with the deliveries.

“My hospital births were very managed,” says Schoenborn. “I wanted privacy and to be free of internal exams. I wanted to give birth in an upright position and they want you to lie down. I feel birth is an instinctive process and in the hospital they treat women like they’re broken and birth like an illness.”

‘I know my body’
Schoenborn also chose not to have prenatal care from a medical professional. That meant no internal exams and no ultrasounds to check for twins and fetal development. “I would know if I was carrying twins,” Schoenborn says. “I know my body.”

For Margulis, the biggest problem in the hospital — and even at home with a midwife — was interference with “normal” labor. When a pregnant woman enters the hospital, Margulis says, she’s signing on for a host of unnecessary interventions, including multiple internal exams, a greatly increased likelihood of receiving the drug oxytocin to speed delivery and also of a Caesarean section.

Margulis’ first baby was born in a hospital and the next two were at home with a midwife. Margulis wasn’t happy with either experience and decided she wanted more control over the process.

After researching the do-it-yourself option, she felt assured the birth process is “safer than taking a shower.”

Margulis cited a recent Canadian study that found giving birth at home with a midwife was about as safe for babies and moms as in a hospital, with the rate of newborn deaths about two per 1,000 for planned home births. The rate of C-sections was a few percentage points higher in hospitals.

However, the women in the studies were very healthy, had no risk factors, and had small-sized babies, says Dr. Harish M. Sehdev, an assistant professor of clinical obstetrics and gynecology and director of labor and delivery at Pennsylvania Hospital in Philadelphia. Hospitals generally have much higher C-section rates because they treat a variety of new moms, including those who are overweight, have big babies and have lots of risk factors like diabetes and high blood pressure.

In addition, one in 20 women who had chosen to give birth at home ended up delivering in the hospital. “And those were the low-risk women,” Sehdev adds.

More important, says midwife Pamela Kane, Margulis is “comparing apples and oranges.” The studies cited by Margulis are looking at home births with midwives present, not unattended births, which are more risky because you don’t have a trained professional nearby who can spot the early warning signs of a serious problem, says Kane, a certified nurse midwife at Pennsylvania Hospital.

And while women like Margulis and Schoenborn may not like being put on a birthing schedule, experts say there are reasons doctors choose to intervene with oxytocin or a C-section if the labor isn’t progressing fast enough. Among them is the risk of damage to the musculature of the pelvic floor if women strain too long, says Sehdev.

When those muscles are damaged, it weakens the moorings that hold the uterus, the bladder and the bowels in place. The impact of that may not be seen till women hit their 50s and 60s, when the organs can unexpectedly drop down into the vaginal canal.

The choices women make might change if they saw the catastrophes that nobody likes to talk about, says Sehdev. “I’ve known women who lost their babies because the baby got stuck and they couldn’t get to the hospital fast enough,” he explains.

Those realities have affected the way Augustine Colebrook looks at unattended births. Colebrook had three children on her own before going back to school to become a midwife so that she could help with births herself.

“I struggle with myself wondering if I would have another kid unattended, after being a midwife for almost 10 years,” says the 33-year-old from Ashland, Ore., who consulted with Margulis during pregnancy. “I think I probably would — it was a life-changing experience. But I’m not sure.”

Margulis, however, says she finally experienced the kind of birth she wanted.

“It was absolutely incredible, a totally empowering experience,” she said. “When you give birth by yourself, you realize how powerful and strong your body is.”

Antioxidants may raise diabetes risk: study

Antioxidants may raise diabetes risk: study

Instead of protecting against diabetes, antioxidants — compounds in foods and supplements that prevent cell damage — may actually increase the chances of getting diabetes, at least in the early stages, Australian researchers reported on Tuesday.

“In the case of early type 2 diabetes … our studies suggest that antioxidants would be bad for you,” Tony Tiganis of Monash University in Australia, whose study appears in the journal Cell Metabolism, said in a statement.

Antioxidants are protective proteins that can prevent cell damage caused by charged particles known as reactive oxygen species. This oxidative stress is thought to add to the progression of several diseases, including type 2 diabetes.

Because antioxidants fight oxidative stress, they have become a popular food supplement. But Tiganis said the picture appears to be a bit more complicated.

“We think there is a delicate balance, and that too much of a good thing — surprise, surprise — might be bad,” he said.

Tiganis’ team studied the effects of oxidative stress in mice fed a high-fat diet for 12 weeks. One group of mice lacked an enzyme known as Gpxl, which helps counter oxidative stress.

They found mice that lacked the enzyme were less likely to develop insulin resistance — an early sign of diabetes — than normal mice. But when they treated the enzyme-deficient mice with an antioxidant, “they lost this advantage and become more ‘diabetic,” Tiganis said in an e-mail.

He said oxidative stress may be working not to damage the body but to inhibit enzymes that hurt the body’s ability to use insulin early on in the development of diabetes, and that antioxidants remove this protective mechanism.

Vaccine raises hope for cocaine addiction therapy

Vaccine raises hope for cocaine addiction therapy

A vaccine helped block the high felt by cocaine users in 38 percent of people who took it, U.S. researchers said on Monday, offering promise of a new approach to treating those addicted to the drug.

The aim is to prevent cocaine’s rewarding effects — the high — in order to reduce cravings that trigger drug relapses.

“The concept works,” Dr. Thomas Kosten of Baylor College of Medicine in Houston, Texas, whose study appears in the Archives of General Psychiatry, said in a statement.

Cocaine molecules on their own are too small to draw the attention of the immune system. To get the body to recognize cocaine, the researchers designed a vaccine that uses a harmless version of the cholera toxin with a few attached cocaine molecules.

When the immune system reacts to the toxin, it makes both cholera and cocaine antibodies.

“These antibodies bind to the cocaine, preventing it from leaving the bloodstream,” Kosten said. An enzyme called cholinesterase breaks down the cocaine and flushes it out of the body.

For the study, Kosten and colleagues studied 94 volunteers — mostly users of crack cocaine, which is a solid, smokable form of the drug — who were on methadone treatment at the Veterans Affairs Connecticut Healthcare System.

Over three months, the participants either got five shots of the vaccine or a placebo injection.

STUDY PLANS

Plans are under way to study the vaccine in many sites.

According to a 2007 National Survey on Drug Use and Health, 35.9 million Americans aged 12 and older reported having used cocaine, and 8.6 million reported having used crack. In 2006, cocaine accounted for about 14 percent of all admissions to drug abuse treatment programs.

Kosten said he plans to tinker with the vaccine to make it more effective. He has already tried a different carrier — a modified version of a meningitis bacterium — supplied by drug firm Merck & Co.

Animal studies showed it produced five times the antibody response as the cholera carrier.

He has used a similar approach on a nicotine vaccine called TA-NIC now being tested in Europe. Both the cocaine and nicotine vaccines are being developed through private equity firm Celtic Pharma.
