Circ stats in sids cases

[mamamillet]

I was just wondering if anyone had actual data regarding the number of intact versus circed babies that died from sids. I have not been able to find any in the research I have. I do know that boys are more at risk and was just wondering if anyone had made the connection between the trauma of circumcisions and sids. Might not even be a connection. Just wondering.

[Pandora114]

no one wants to LOOK at the possible link.

Hevan forbid we put a kink in the cash flow by pointing out something that obvious..

[Eman'smom]

Wow you know I've never even though of that but it makes sense.

Also this "back to sleep" campain is also happening at the same time as the decrease in circing.

Wonder how we'd find the info

Boys are more at risk for almost everything b/c it takes a lot longer for their systems to mature, and they're always more fragile. They're never as sturdy as girls, even as adults. They may be physically stronger, but that doesn't mean their bodies work as well. Micro-premie girls make it a lot more often than boys.

I doubt circ has anything to do w/ it although it might play a small part.

In Europe/Germany, boys are also more at risk of dying from SIDS. I did a quick search for numbers and rates, but didn't find much data with a cleary stated origin (might have been world-wide numbers). Anyway, I found those:

429 SIDS deaths, 272 boys and 157 girls, in Germany in the year 2001
63% boys and 37% girls or a 1.7 times higher risk for boys

So it's clear that even without RIC, boys do have a higher risk (the difference can't be caused by the low percentage of religious neonatal circumcisions performed in Germany). Still, circumcision could be one factor. If the US rates are significantly different, there might be a connection to circumcision, but it would still be far from any proof, of course.

Totally random thought, perhaps boys are more at risk for sids because the xy chromosome isn't as robust as the xx chromosome, meaning that if something is wrong with the x in the xy, there isn't another x to support it? Just random thinking...

I'm not positive I understand what you are asking but let me give it a whirl.

The XX or XY chromosomes are paired off and bonded together. There is a pair in every cell in the body, or in other words, billions of them and they are all identical. So, if one is defective, they are all defective. This is how DNA testing works. Although hair and semen are very different, they both contain exactly the same DNA so they can test the semen sample from a rape victim against hair from the suspect and see if their is a match. It would be the same way with chromosomes. The X chromosomes are not free floating in the body with the ability to connect with free floating X's or Y's to make up a complete unit.

On the topic of a SIDS/circumcision relationship, I don't know of any research that has been done on the subject but several years ago, I saw a writing by a doctor to a medical journal that supposed a link. He had some numbers showing the differences in the occurance of SIDS in different populations and there did appear to be a slight correlation but it was not significant. I suspect that this would be one of those issues that because of the small differences, it would be near impossible to eliminate all confounders to get accurate results.

Another theory here -- perhaps boys are not held as much. Girls might get held, comforted and sleep with parents more while boys are expected to "toughen up" and be independent right off the bat. Therefore, parents may miss important warning signs or ignore distress signals more with boys while girls are having their temperatures and breathing regulated more by being held.

Again - just a theory -- I had no idea there was such a discrepency in gender with regards to SIDS.

Yes, but your xx or xy chromosomes have different genes on them. That's why you can have sex-linked disorders that only express themselves in males, for example, although females may carry the recessive gene. A female will have dominant gene on one x chromosome and recessive gene on the other x chromosome, and will not express the disorder. A male, though, will have recessive gene on the x chromosome and nothing on the (shorter) y chromosome, and will express the disorder.

and to even make it more interesting, just saw a health channel special on chimeras- people with two sets of dna. fun when trying to prove parentage. (so yes, there can be one set of dna in your hair & another in your kidney!)

I read an extremely interesting article a while back about a woman, maybe in England? who had different DNA in her reproductive system and elsewhere in her body (probably because of vanishing twin syndrome) which they discovered when they "proved" in a hospital that her son wasn't really her son....and she was, like, "Ummm, excuse me, he is my son, I PUSHED HIM OUT!!" So they investigated further and sure enough, she had two sets of DNA.

ETA: link to story

Another story about the same woman

I saw that a week or so ago as well. It was very interesting. She had 3 children (2 or 3?) and they court took them away saying they weren't hers, she must have kidnapped them. She finally got her 3 kids back when she gave birth in a hospital to her 4th who 'wasn't her child' though she had just given birth to it.

as for the topic... :)

I found this thread after someone asked the same question on tribe.net.

Here's a site where someone has listed the info we do have to look at at this point...

All of those facts are correlational, but not necessarily causational. (In other words, yes, those are all present in the U.S., but that doesn't mean that one CAUSES another.)

However, that doesn't explain the drop in girls' SIDS rates during the "Back to Sleep" campaign.

The connecting factor between boys and SIDS is metabolism/heat. The AAP lists overheating/overbundling as a SIDS risk factor, and boys have higher metabolisms, so they are more likely to overheat and die of SIDS.

That's right-
as she says in the first line, she's presenting her "pure speculation."

I doubt circ has anything to do w/ it although it might play a small part.

Boys are also at higher risk for stillbirth (which obviously has nothing to do with circ) and it is believed by many that there is a connection between stillbirth and SIDS.

When our son, intact of course, was a newborn we tried laying him on his back to sleep. He simply refused. He wanted to lie on his stomach or side. The first couple of nights I hovered over him, terrified of the unthinkable. Then I noticed something, his head was turned to the side, and his airway was completely clear. Then when he was about three months old I read a section in Dr. Sears' Baby Book that described the risk factors for SIDS. Prematurity, parents who smoked and/or a mother who smoked while pregnant, sorry I forgot the rest but I do know that once I read it I never once worried about SIDS again. Okay, and for the record, I know it's a horrible tragedy and that no one can ever comprehend the loss of a baby if they haven't experienced it. But I just know that from my research the risk seemed to insignificant that I preferred to let him sleep comfortably than cry for an hour because he wasn't happy.

Actually that's exactly why. I saw a show on it on DSC. That is also why men are more vulnerable to things like colorblindness and many diseases that are carried on the X chromosome. Where in a woman 99% of the time there's a 'good' X to override the bad one, in a guy he only gets the one X. So if it carries the gene for colorblindness or whatever ( I don't remember the others) he has it.
