As Babies Are Born Earlier, They Risk Problems Later
mutate "...late-preterm babies are about five times as likely to die in the first
week of life and about three times as likely to die in the first year than full-term babies, studies show." "Some studies have found evidence that these babies are more likely to have subtle problems with speech development and coordination and behavioral and learning difficulties." "...researchers suspect they may also be at increased risk for behavioral problems such as hyperactivity and possibly cerebral palsy and mental retardation." ________________ Good to see that the Post ran this story on the front page. But Teresa is right to point out the glaring absence of any concern for the possibility -- make that likelihood -- that toxic chemicals or pseudo-hormones are a contributing factor in the increasing rate of prematurity. (Now why does this seem familiar?) It seems to me that it would be quite feasible for the EPA and/or the NIH to create a monitoring program to look for a correlation by comparing body burdens of suspect chemicals in premature births with full-term births. (Preferably by using maternal blood and hair samples, along with cord-blood, placental tissue and hair from the babies -- but NOT by subjecting newborns to the taking of blood samples. They DO feel pain!) If the Federal agencies won't look into it, then some of the states (California, New York, New Jersey, etc.) should take this on. It will probably take a goodly number of years to identify all of the specific chemicals that may be involved (although we already know of dozens that can cause developmental problems for fetuses). But I would think that we would have at least a general indication of such a correlation even with the preliminary data (provided the sample size was large enough.) Ironically, the three factors that *are* pointed to in this article are ALL linked to higher socio-economic class -- very much the opposite of what you would otherwise expect. Maybe "prosperity" isn't all it's cracked up to be. By the way -- the article is rather misleading when it refers to babies "being born just shy of" full-term or "slightly early". That sounds like a week or two shy of 40 weeks -- not 4 to 6 weeks early, as explained half-way down. That's major.

Teresa * * * ** As Babies Are Born Earlier, They Risk Problems Later* By Rob Stein Washington Post Staff Writer Saturday, May 20, 2006; A01 http://www.washingtonpost.com/wp-dyn/content/article/2006/05/19/AR2006051901702.html [foto] Becky Veduccio of Bloomfield, N.J., said daughter Sophie spent several days in intensive care after being delivered 3-1/2 weeks early. (By Russ Veduccio) More and more babies each year are being born just shy of spending a full pregnancy in their mothers' wombs, putting more infants at risk of health and possibly developmental problems because they enter the world before they are ready. The percentage of babies born slightly early has been increasing steadily for more than a decade and is now at an all-time high. So many babies are being born a few weeks early -- more than 350,000 annually -- that the average U.S. pregnancy has shortened from 40 weeks to 39. The increase is driven by a combination of social and medical trends, including the older age of many mothers, the rising use of fertility treatments and the decision by more women to choose when they will deliver. At the same time, medical advances are enabling doctors to detect problem pregnancies earlier and to improve care for premature babies, prompting them to deliver more babies early when something threatens their lives or those of their mothers. Many obstetricians argue that the trend is positive overall because they are preventing thousands of stillbirths and avoiding potentially serious risks for mothers. But other experts worry because these babies are prone to a long list of serious, potentially life-threatening complications, which often require intensive, costly treatment. Moreover, growing evidence suggests that their long-term development may be more problematic. "We should be concerned about these babies," said Tonse N.K. Raju of the National Institute of Child Health and Human Development. "They have more short-term problems, and there is evolving evidence that they have long-term risks as well." Although most of these babies fare well and face far less risk than very premature infants, researchers have begun to realize that they are nevertheless more prone to short-term complications, such as problems breathing and feeding, and jaundice. And because so many are being born each year, even a small increased risk translates into thousands of sick babies. Studies are also starting to suggest that these children may tend to not develop as well as full-term babies, leading to behavioral, learning and other difficulties. "There's no question these babies tend to have more [immediate] problems compared to full-term babies," said Richard E. Behrman of the Federation of Pediatric Organizations, who chairs a panel assembled by the National Academy of Sciences that will issue recommendations on the rising late-preterm birth rate next month. "The concern is about whether there is some adverse impact on their long-term development." For years, most of the attention focused on the earliest, smallest "preemies" -- those born before 32 weeks -- because they face the greatest risks of dying or having permanent disabilities, such as cerebral palsy, deafness and blindness. But the proportion of babies born that early has leveled off, while the rate of "near-term" or "late-preterm" births -- between 34 and 36 weeks -- continues to rise. They now account for about two-thirds of all preterm births. "These kids have been below the radar screen," said Marie C. McCormick of the Harvard School of Public Health. "They're just starting to get our attention." Nearly 9 percent of all babies delivered in the United States were born late-preterm in 2003, according to the most recent federal data. That is up from 7.6 percent a decade earlier and the highest since the government started tracking such births -- and translates into about 50,000 more of these babies each year. "It's a huge increase," said Mary E. D'Alton of Columbia University. "The question is: Are we doing too many of these deliveries?" While the precise cause of the increase is unclear, one reason is that more women are delaying childbearing until their thirties, when they are prone to complications, including premature labor. Older women are also more likely to need fertility treatments, which increase the chances of having twins and triplets -- which tend to be born early. The obesity epidemic may also play a role -- obese women have more complications, such as high blood pressure and diabetes, that can make it necessary to end a pregnancy early. Medical advances are making it easier to spot babies who are in distress or developing poorly, prompting doctors to deliver them early -- either by Caesarean section or by inducing labor with drugs -- to prevent stillbirths. Techniques for caring for premature babies have also improved, giving physicians more confidence that a baby will survive if delivered early. That makes them more likely to suggest an early delivery at any hint of a problem that might endanger the mother or baby -- or risk a lawsuit. "In the past they wouldn't have dared -- they would have tried to wait it out," McCormick said. "Now they know what the neonatal intensive-care unit can do. That's been a very powerful, powerful change." So powerful, obstetricians say, that the rate of stillbirths has dropped and the chances that a premature baby will survive have risen sharply. "We shouldn't be worried," said Charles J. Lockwood of the Yale University School of Medicine. "We're doing a good job of avoiding stillbirths and subsequent infant mortality. When you have a fetus with no growth or insufficient food, the better place for that fetus is outside the womb." But some specialists question whether the increase in Caesareans and inductions is the reason for the drop in stillbirths. And they worry that too much of the increase may be due to women hastening delivery for nonmedical reasons -- they want to make sure their mother will be in town, their husband has a business trip pending, or they are just fed up with being pregnant. "It's a common request," said Mark Lollar, an obstetrician in San Ramon, Calif., who routinely honors such requests for the wives of professional athletes so their husbands can be present. "I have no problem arranging that for them." Lollar and other obstetricians insist that they make sure that the fetus is at least 38 weeks old. "We never compromise the mother or the baby's safety," Lollar said. Other experts, however, say it can be difficult to calculate the precise gestational age of a fetus. "If a woman comes in late in the pregnancy and only has one ultrasound, you can have an error of up to two weeks, which can be significant," Tonse said. After losing her first baby three days before her due date, Becky Veduccio and her doctor decided to induce labor in March just before her 37th week. Her daughter, Sophie, spent several days in intensive care getting breathing help, antibiotics and intravenous fluids. Less than a week later she was readmitted to the hospital for jaundice, and she has had digestive problems ever since. "I thought 36 1/2 weeks would be okay," said Veduccio of Bloomfield, N.J. "But it's been just torturous. Every time we thought we could relax, something else would happen." The lungs, brains and other organs of babies born even a week or two early are often underdeveloped, making the infants much more likely to have problems breathing, maintaining their body temperature and feeding. They are also vulnerable to infections and jaundice, which can be life-threatening or cause brain damage. Such complications often require them to be sustained in the hospital for a week or two until they are fit to go home, adding thousands of dollars to the cost of their care. Often, they end up being readmitted once doctors realize they are not quite fully formed. "These babies often masquerade as term babies," said Elizabeth A. Catlin of Massachusetts General Hospital in Boston. "They look like full-term babies -- they are chubby, they have a head of hair. But they just don't have the maturity and development of full-term babies." In addition to the added cost and anxiety the complications cause, late-preterm babies are about five times as likely to die in the first week of life and about three times as likely to die in the first year than full-term babies, studies show. "Doctors ought to be aware that there's no free lunch," said Michael Kramer of McGill University in Montreal. "There are a lot more babies out there who are getting sick and dying." Although very little research has been done on these babies' long-term well-being, researchers suspect they may also be at increased risk for behavioral problems such as hyperactivity and possibly cerebral palsy and mental retardation. "Could this group of babies be contributing significantly to the total burden of mental retardation in the United States and the world?" asked Gabriel J. Escobar of Kaiser Permanente Medical Care Program in Oakland, Calif. "I would say yes. We don't know how much, but it's not trivial." Some studies have found evidence that these babies are more likely to have subtle problems with speech development and coordination and behavioral and learning difficulties. "The thinking had been that these babies were basically the same as term babies," said Steven B. Morse of the University of Florida. "Now it looks like they really are different." Morse presented a study at a conference in San Francisco this month that found late-preterm babies were significantly more likely to fall behind in reaching language, coordination and developmental benchmarks at age 3, were less likely to be ready to start preschool at age 4, and were more likely to need special-education classes, have behavioral problems and be held back in kindergarten. "A lot of brain maturation occurs in those last few weeks," he said. "How the brain develops when the baby is still inside the mother may be different than how it develops when it is outside. If these kinds of development problems persist for these children, that is a concern from a societal standpoint."
