When I saw the headline of a TIME article that read “Why U.S. Infants Die Too Often“, I clicked over thinking that it would be something about prenatal care or this test or that test that we’re not running but should be or maybe this procedure or that procedure that we are or are not performing. Instead, I got something that made me want to throw something at my computer monitor. Here is the logic of the article and of Marian MacDorman, the statistician that they consulted:
One of the main [factors] is whether the baby is delivered too small or too soon, which increases its chances of death. About two-thirds of all of our infant deaths occur among the 8.2% of babies that are born at low birth weight. Most developed countries have lower rates of preterm and low birth weight deliveries [than the U.S.] and that makes a difference in infant mortality rates. {…}
There are a lot of doctors who say it’s O.K. to take a baby out a little bit early because they’re going to do well — and it’s true. It’s only seven per 1,000 that are dying. Most of them do well. But still I think it’s important to note that the infant mortality rate for late-preterm infants is three times what it is for [full-]term infants.
One gets the image of doctors saying “I am just booked solid next week, so let’s deliver this baby a week early cause I don’t want to have to work late.”
In reality, when babies are delivered preterm, it’s because there is already some sort of problem and not because doctors don’t know as much about medicine as do statisticians. Granted, I am the husband of a doctor (who has done a lot of work in obstetrics) and that influences my perspective. Not because I believe doctors are perfect just cause my wife happens to be, but rather because I get to hear a lot about the ins and outs of following pregnancy and delivering babies. My wife is more conservative than most doctors and has in the past complained about the pro-active attitude some doctors take about inducing labor. What she hasn’t complained about, though, are doctors purposefully delivering babies that they believe to be healthy ‘just cuz’.
Doctors and hospitals make the determination about whether to deliver early based on the baby’s chances of survival in the whom and out of it. It’s quite possible that these calculations are flawed and they overestimate the threat to the baby in utero. If MacDorman has statistics that suggest that our efforts to avoid miscarriages and stillborns and all that are overly aggressive, you are going to have to look at alot more than infant death rates. Without information about miscarriages under this scenario or that, the numbers that McDorman cites are not particularly helpful. When it comes to infant mortality, there have to be infants involved. Delivering a baby preterm that dies counts as a strike against us, but a baby that dies before being born doesn’t count either way.
American doctors and American hospitals are much, much more conscientious of pre-birth deaths than a lot of other countries. A lot of it you can chalk up to the fact that a dead fetus leaves them financially vulnerable than doctors in other countries. To the extent that doctors may jump the gun, it’s because it’s a lot easier to get sued for being perceived as doing too little than it is for being perceived as having done too much. It’s this far more than anything else that might lead to this error. But we also live in a culture with a more protective attitude towards fetuses than many others. Sometimes, as in the case of jury awards, too much so. Also, though, because it leads us to deliver babies using resources that might better be directed elsewhere.
The hospital that Clancy worked at down here had very, very aggressive fetus-saving policies. It lead to babies being delivered earlier than any baby has even a remote chance for survival beyond a few days. But nonetheless they deliver the baby. They do everything they can within (and beyond) reason to prolong the life for as long as they can. The result is a dead baby and a slightly higher infant mortality rate. When working in Deseret, one of the higher ups was a doctor from Britain who commented with astonishment the lengths that American health care goes for (seemingly) lost causes.
While it’s quite possible that we don’t have a greater need for preterm deliveries than other countries, it’s possible that we do for at least a couple reasons that come to mind:
- Heroic measures: As mentioned above, we deliver babies that other countries may not even try to. This may be unwise on our part, but not necessarily for the reasons that MacDorman implies.
- Poor prenatal care: A lack of prenatal care can mean that little problems that go unaddressed earlier in the pregnancy become bigger problems later on. We also have higher instances of drug use, which can not only cause natural preterm labor and complications that require induced labor or cesarians, but it also leads to mothers failing to seek out prenatal care because they don’t want to get caught with drugs in their system. This one wouldn’t have occurred to me, but Clancy has reported it on more than a few occasions. It’s probably worthy of a post.
- Fertilization drugs: Fertilization drugs are very common in the US. Moreso, I’d imagine, than many other developed countries because our religions more vigorously promote procreation than a lot of other countries do. It’s noteworthy that multiple-births are more common in religious conservative states than in blue ones. Fertility drugs cause multiple-births. Multiple-births shorten the expected length of the
presidencypregnancy by something like 4 weeks per extra baby.
MacDorman seems to recognize that there may be contributing factors in the last couple of paragraphs but only as they pertain to comparing the demographics of which babies are prematurely delivered most often. Would that she were interested in contributing factors in comparing the US to other nations beyond the simple conclusion that she’s smarter than the doctors.

It’s actually illogical that Americans place so much more emphasis on prolonging life than do the Europeans considering that we’re so much more religious. To the typical American, death means spending eternity in Paradise with Jesus, while to the typical atheistic European death means oblivion. Yet we fear it so much more. Go figure.

In the next-to-last paragraph, I think you meant “pregnancy”, not “presidency”.
If only it the latter were true!

Peter, I think that the counterbalance to the whole good-life-after-death is that life should be preserved when possible. I think that the only way to prevent everyone from killing themselves and loved ones is to place greater importance on live your life on course. That’s the more charitable explanation. The less charitable is that people are less certain about the afterlife as they think they are.
Thanks for the correction, Linus.

Another factor in the US’s high infant mortality rate is that black women, for reasons not clearly understood, have a very high infant mortality rate–something like 3 times that of white women.
It’s not simply a matter of access to health care–a differential remains even when controlling for SES, and Hispanics (except Puerto Ricans) actually have a slightly lower rate of infant mortality than whites.
Whatever the reason, it’s a factor that other nations don’t have to deal with, and it underscores the problems with a naive comparison of health care “outcomes” across populations.

The article gives a hat-tip to the subject of race, though frustratingly it doesn’t consider that the circumstances might be different between nations as it is between ethnic groups. MacDorman says that there are no simple answers for the race disparity, but then seems perfectly willing to give a very simple answer for national disparities.

Determining whether there’s a non-SES-related link between a medical condition and race is complicated by the fact that race in America is more social and cultural than biological. Infant mortality may be higher among babies born to black women doesn’t prove an infant mortality/race link because it’s entirely possible, even likely, that many of the black mothers are actually partly or mostly white in genetic terms. Think of Mariah Carey or Alicia Keys, for example.

Peter, that there is a link between race and infant mortality is pretty established. What causes it is what we don’t know. We do know, however, that it’s not simply a matter of SES. Hispanics have lower SES than whites and a lower infant mortality rate. Tribespeople have lower SES than blacks and also a significantly lower infant mortality rate (though the IHS may be responsible for some of this). That’s in addition to the SES controls placed into studies.
That being said, I’m not particularly concerned what the cause is as far as this post goes. I hope that scientists and doctors continue to look into it, but whether it’s due to genetics or culture or something else, it would not appear to be because doctors are willy-nilly taking babies out too early. And it remains a good example of why comparing infant mortality rates between nations is tricky stuff.
On this subject, Brandon’s point about racial breakdowns was good and pertinent to the discussion (particularly since it is in the article). However, I don’t want that to be the foot-in-the-door for a discussion on more general distinctions between races. As long as we’re keeping it about procreation, though, we should be fine. So far, so good.

Statistics from Britain might help shed light on whether blacks have a higher infant mortality rate independent of SES and access to health care. Britain’s got a substantial black minority, universal access to health care, and a group with lower SES than blacks (Pakistanis) for purposes of comparison. Should the higher black infant mortality rate be the case in Britain too, it would be strong evidence that it’s not something specific to the United States.
