Skip to comments.BPA Exposure and Obesity in Children: Just a Correlation?
Posted on 09/09/2013 6:19:41 PM PDT by Pharmboy
KidsChemicalSafety.org provides up-to-date health information on chemical hazards and safe use of chemicals around children, so we asked Dr. Micheal Dourson, of Toxicology Excellence for Risk Assessment (TERA), to comment on a recent article, Eng et al. (2013) that found higher levels of bisphenol A were associated with several measures of obesity in children.
Specifically, children exposed to higher levels of bisphenol A had increased odds of having a body mass index in the 95th percentile (i.e., greater than 95% of all children) and a waist circumference to height ratio (WC) greater than a value of 0.5. However, several other measures of obesity were unaffected, such as abnormal body fat percentage, BMI and WC thresholds below 95th percentile, and other laboratory measurements of cardiovascular disease and diabetes (e.g., total cholesterol, HDL, LDL, fasting triglycerides, insulin resistance, and fasting glucose).

Ping your list, please, Black Agnes.
Beware the junk science. Saw this earlier and there are several red lights. Advocacy <> Science. Grain of salt ya know? Just sayin.
This is a pretty good study:
Any estrogen mimic, particularly during pregnancy, has long term consequences for the germline. Multigenerational effects in fact. Epigenetics is much bad mojo to mess up.
I’m not aware of another group of animals that has a more limited and weighed, measured and counted diet.
The calories that was sufficient, but no more, for the same lab animals 40 years ago. Makes them fat today...
I’ve never seen a coke machine hooked up to a lab cage. Or a video game in one either.
Environmental compounds are known to promote epigenetic transgenerational inheritance of adult onset disease in subsequent generations (F1F3) following ancestral exposure during fetal gonadal sex determination.
The only issue I have so far is there is no mention of Brawndo :)
When the authors offer many cautions about their own study and point out the shortcomings, it is good science and up to community standards.
And, as they importantly point out with an illustrative story about ice cream, association does NOT mean causality; however, it can point one in the direction of truth (although not always).
Thanks Pharm I should have indicated you are preaching to the choir on BPA. I get it. I just objected (lightly) to the min-hype of another org claiming objectivity in a sea of subjectivity. Science no longer matters of course. If it did, we would not be having this conversation right?
Yep. And drinking soda pop from cans that are lined with this stuff, as if the sugar isn’t bad enough.
From the details revealed about the “study” it is easy see that it is not really a “study”. It is lacking so much methodology that it is laughable.
This is no more than a paper postulating that BPA and obesity should be studied.
Reminds me of the fish oil “study” that supposedly shows aggressive prostate cancer resulting from fish oil consumption. I did some further investigation on that one and it is absolutely worthless on a number of levels.
There are a whole lot of things necessary to constitute a good scientific study, this has none of them.
This is just another bit of correlative data that says, "keep looking, there may be something there."
This is just one correlative study that should not be over-interpreted, but the totality of evidence deserves respect. Have a look for yourself.
This would explain the weight loss/soda studies that indicated weight GAIN regardless of the soda sugar content. Even diet soda is linked to weight gain. Of course, the containers are all lined with a weight promoting estrogen mimic.
I’m convinced enough that my family avoids wherever it might be found.
You wouldn’t believe how darned inconvenient that is too.
There are serious weight problems in my family and my husband and I are both overweight.
My kids have avoided the stuff for the past 4 years and, strangely enough, for a ‘genetic’ affliction they’re not overweight. Any of them.
The rat study was interesting.
I want an multi-generational primate study.
And it makes me wonder just what other ‘GRAS’ compounds affect us epigenetically for the worse...
I’m not stating an opinion on BPA, just the incorrect and over use of the term “study”.
Frankly, I don’t care anymore about much of this. I’ve got “study fatigue”.
It’s tough to fight your genes, that’s for certain.
You want to live a long and healthy life? Pick the right parents before you are born.
Nonetheless, the aforementioned doesn’t constitute a study. BPA may be a bad thing, but that is not relevant to the fact that this is not a real study. It is someone suggesting that studies ought to be considered.
The paper in the link with the ‘plosone’ in the http that I posted IS a real study.
A multigenerational study.
Complete with sac’d and autopsied animals.
But, do this. Have a look at highschool yearbooks from this country, rural ones, from the 1930’s. Look at the 18yr old high school senior boys. They have square jaws, stubble and chest hair. Broad shoulders too.
They also had deep voices.
Now, look at the same senior boys in the class of 2013. Completely different. They’re all MUCH more effete, physically. And NONE of them have deep voices like their grandfathers had. And in this year’s yearbook you’ll find a surprising number of broad shouldered individuals. Sadly, most of them are the senior GIRLS.
Something is turning a large number of our male offspring into effete shadows of their former selves. Male sperm counts around the world have fallen off a cliff over the past 2 generations. WHO has had to redefine the number below what’s considered ‘infertile’ several times.
What hasn’t been done yet is a primate study or human study of the same kind. Human study would take decades due to the generational time gap between f0’s and f3’s. A monkey study, on the other hand, should have already been started.
But, the elites are hell bent on controlling OUR population (so their offspring can inherit an unspoiled planet!), so I don’t really expect much to become of any study, whether it’s relevant and well thought out or not.
