Obese women birth supersized babies? Obese babies on the rise

Big baby boom: Supersize deliveries have doctors worried

Michelle Cessna said she was shocked when her daughter Addyson was born on July 11 weighing 13 pounds, 12 ounces.

A month after delivering a 13-pound, 12-ounce baby girl, Pennsylvania mom Michelle Cessna is reveling in the healthy arrival of her “little blessing” while also scrambling to re-stock her diaper supply.

“We had to exchange all our little diapers for bigger ones,” Cessna, 37, says with a laugh. And baby Addyson shot right past newborn clothes and left the hospital dressed in an outfit meant for a 3-month-old.

Addyson Cessna joins a small but growing club of giant babies making headlines. So far this summer, a German baby girl weighed in at nearly 13 and a half pounds; a California woman had a 13-pound, 10-ounce girl; and just last week, a British mom in Spain gave birth to a 13-pound, 11-ounce daughter. 

And back in March, a British mom gave birth — naturally — to a 15-pound, 7-ounce son.

All these whopping newborns are starting to leave moms-to-be a tad nervous — and some doctors concerned. 

For many moms around the world, the risk of having a big baby has increased along with rising rates of obesity, and the higher rates of gestational diabetes that come with delaying childbearing. And while everyone loves a chubby newborn, a baby who is too large at birth can face a constellation of health issues ranging from a difficult birth to an increased risk of obesity later in life.

Overall, there’s been a 15 percent to 25 percent increase in babies weighing 8 pounds, 13 ounces or more (or 4,000 grams, the weight where a baby is considered oversized) in the past two to three decades in developed countries, according to a February report in the medical journal The Lancet..

Most surprisingly, the developing world has also started seeing an increase in big babies. The Lancet study found that nearly 15 percent of babies born in Algeria — where maternal obesity is almost 30 percent — fit that category. In China, which has been coping with rapidly rising obesity rates, 6.9 percent were big. By comparison, in India, where maternal obesity is only 3.6 percent, a scant 0.5 percent of newborns were very large.

Baby girl Jasleen, born in Germany on July 29, weighed over 13 pounds at birth. Her mother had undiagnosed gestational diabetes.

In the U.S., where maternal obesity has been an issue for longer, doctors have become more aggressive, intervening before babies get eye-poppingly large. Those efforts seemed to have flipped the big baby trend around and the average birth weight has actually started to decline.

Rates of C-sections climbed from 20 percent in 1996 to 31 percent in 2009 and labor inductions are also on the rise, according to the Centers for Disease Control and Prevention.

That’s partly due to the dangers associated with preeclampsia and other blood pressure problems sparked by pregnancy in obese women. It’s also partly due to the rise in the number of large-for-gestation fetuses.

“In the past, say the ‘80s, women often weren’t considered for induction unless they didn’t go into labor on their own by 41 to 43 weeks. Now it’s between 39 and 41. So babies don’t have a chance to get bigger in those later gestational weeks,” Dr. Robert Barbieri, a professor of obstetrics and gynecology at the Harvard Medical School and chief of obstetrics and gynecology at Harvard’s Brigham and Women’s Hospital.

Harvard research showed that by 2006, there was an almost 100 percent drop in the number of births that went beyond 41 weeks

Big babies can pose risk to both the mother and child at birth. They are at risk for shoulder dystocia – which means that the shoulders have grown so big that they can get stuck under the mom’s pubic bone during delivery. Normally the head is the largest part of a baby, but when babies grow so big, the shoulders can become larger than the head.

When babies get stuck, they can end up with fractured bones and the moms can end up with trauma and tearing, Barbieri says.

Along with the risk of a difficult birth, there is the impact on the health of the babies once they are born, says Dr. Irina Burd, an assistant professor of gynecology and obstetrics and neurology and director of the integrated research center for fetal medicine at Johns Hopkins Medicine.

It’s not uncommon for overweight moms to have diabetes or to develop it during pregnancy. And some of the high blood sugar in the mom flows through the placenta to the baby. That, in turn, forces the baby’s pancreas to pump up insulin production, which can leave babies with low blood sugar after they are born, Burd says.

Another problem is that sugar acts like a growth factor, and not all the growth is in sync, says Dr. Hyagriv Simhan, chief of maternal fetal medicine and vice chair for obstetrics at McGee Women’s Hospital at the University of Pittsburgh Medical Center.

“In some ways very large babies look more mature because of their size,” Simhan adds. “But in terms of their lungs, they may be immature.”

Even more concerning are the effects felt by big babies as they grow up. “So they’re not just obese at delivery, but there are epigenetic changes that program them for the rest of their lives,” Burd says. And those include a heightened risk for obesity and cancer, she says.

That’s why doctors have tried to encourage pregnant patients who are obese to gain very little weight during pregnancy.

For women who can’t seem to keep their weight down, there may eventually be another solution. An ongoing clinical trial is looking at the impact of a drug that helps keep blood sugar low in pregnant women who are obese.

In some cases, such as Michelle Cessna’s new daughter, big babies may just run in the family. She said she had no health issues during her pregnancy and safely delivered Addyson, who measured 25 inches, by C-section at 39 weeks. Her two older sons weighed roughly 10 and 11 pounds when they were born.

“I think it runs in my husband’s family,” she said. “He was 9-pounds something. He had an uncle who was 14 pounds.”

She said she still gets quizzed about Addyson when she heads into the community she lives in near Pittsburgh. People ask the usual: How much was she at birth? They hear the number and typically offer the same remark: “Oh, that’s the baby that was on (local) TV. She doesn’t look as big as she did on TV.”

“She doesn’t look big – for a 3-month old,” Cessna says of her 1-month-old girl.

I am obese and was when DS was born. They thought he would be over 9 lbs so they took him 2 wks early. He was 6lbs 24 oz.

Eta: 14 oz not 24

I'm obese.  I lost 25 pounds during pregnancy.  DD was premature at 3 lbs. 14 oz.

I'm obese and have been since I was a teenager. My kids were both 7 1/2 lbs at birth.
by Platinum Member on Aug. 17, 2013 at 11:33 AM

I had my son when I was 18. I was never a really big girl but my son was born at almost 10 lbs. Big babies run in my family though. My older sister was 9 lbs, I was 10 lbs and my younger sister almost clocked in at 11 lbs.

Really? 5'5", 118#......delivered a 10#, 23" baby.

My Mom....5'8", 120#....delivered a 13# baby.

I'm fat and I've had an 8 lb, 8 lb. 6 oz, and 8 lb. 15 oz.

Now, the one I lost was 9 lb. 13 oz, but she was two weeks past my due date. I did not have GD with any of them and was at my smallest with the first one.

Exactly the same as the range my sibs and I were at birth and my mother was not fat at all at that time.

I think it is more of a genetic and better nutrition thing, absent GD.

Correlation does not equal causation.

by Silver Member on Aug. 17, 2013 at 12:20 PM

I can see how there could be a correlation, but I think there can be a lot of factors.  I was fit and healthy with my son, yet I gained a lot of weight and he was just shy of 10lbs.

I was obese with my daughter, but my doctor was supportive yet cautious.  I didn't gain a lot (less than 20lbs) and she was 8lbs.

I am very small and had smaller but still normal sized babies, about 7 1/2 lbs.

by Emerald Member on Aug. 17, 2013 at 12:28 PM

I have always heard that your size at birth has more to do with it

I am fat. My kids were 8'12 and 6'12.  I was 8'12 when i was born

My niece was 9 lbs as was my sister when she was born

Quoting LoveMyBoyK:

I am obese and was when DS was born. They thought he would be over 9 lbs so they took him 2 wks early. He was 6lbs 24 oz.

by Angie on Aug. 17, 2013 at 12:29 PM

Considering that babies generally double their birth weight by 6 months or up, this could be a problem?  I don't know, though.  I'm very small and every single baby I had weighed in at 6lbs 8oz without fail.
