Childhood Obesity Linked To Air Pollution From Vehicles (theguardian.com)
Early exposure to air pollution from vehicles increases the risk of children becoming obese, new research has found. From a report: High levels of nitrogen dioxide, which is emitted by diesel engines, in the first year of life led to significantly faster weight gain later, the scientists found. Other pollutants produced by road traffic have also been linked to obesity in children by recent studies. Nitrogen dioxide pollution is at illegal levels in most urban areas in the UK and the government has lost three times in the high court over the inadequacy of its plans. The pollutant also plagues many cities in Europe and around the world. "We would urge parents to be mindful where their young children spend their time, especially considering if those areas are near major roads," said Jeniffer Kim, at the University of Southern California, who led the new research. "The first year of life is a period of rapid development of various systems in the body [and] may prime the body's future development." The World Health Organization (WHO) revealed last Monday that 90% of the world's children are breathing unsafe air, a situation described as "inexcusable" by the WHO's head. Concern over the impact of toxic air on children's health is rising as research reveals serious long-term damage to both their physical and mental health.
and eating too much. probably more the fault.
High Fructose Corn Syrup? Make since given the ethanol added.
I could swear that people are just looking at http://tylervigen.com/spurious... for ideas to make new headlines with.
Some days I get the sinking feeling Orwell was an optimist.
Pollution standards are far stricter than they used to be, so we should be seeing a decrease in obesity if this is such a major factor.
These are just environmental activists who are trying to exploit "intersectionality" with the well-publicised obesity epidemic, so as to promote their war on mankind's industrialisation.
You'll never convince mankind to tear down its hard-won development. Make better machines, or STFU.

No need to blame bad diet and lack of exercise. Now we know it's the fault of cars.
As a supporting anecdote. It turns out that if we eliminate cars and make the little fuckers walk to school, and everywhere else for that matter, they lose weight. Go figure!
when you can't get as much oxygen into your system you can't exercise as much. Cyclists (of which I am one) have known this for a long time.
I wish we could get the environmentalist crowd to stop banging on about shaving whales and talk more about stuff like this.

Parents needed a new reason to be paranoid and overprotective. That's never been a bad thing.
On a serious note, I grew up in Pittsburgh. Prior the 1980s, the air was exceptionally unsafe. Since then, it's only been getting cleaner. What's the trend line for obesity look like? Spoiler: obesity is going up and up, while the air is cleaner than it's ever been for nearly 40 years. Therefore if bad air was thing, you'd expect the exact opposite.
Alarmist news reports over spurious correlations do not help people. They only make your average person lose trust in science. That's not particularly a good thing.
You cyclists are all the same.
Don't know whale shaving. You've clearly never tried it.
And I'll say it again: The best possible thing that could happen for both the planet AND human beings is for the price of oil to skyrocket. Would it cause an economic disaster? Probably. Would it be worth it? Without a single doubt.
"High levels of nitrogen dioxide, which is emitted by diesel engines".....and oil furnaces (because they use the same fuel)

sunspots have risen too.
Some drink at the fountain of knowledge. Others just gargle.
But that is too obvious, lets blame the big CO2 monster!
Hypothesis: It's due to people consuming that crap
cuz you know... thin people got killed in the war, so their thin genes are not in the pool anymore and are replaced with fat people that can't go to war and use the m4...
Nitrogen oxide formation is not dependent on the fuel, but on the combustion process. The nitrogen and oxygen come from the air. Any combustion produces some level of NOx. The leaner and hotter, the combustion, the more you get, independent of fuel.
The subjects are ingesting more calories than their bodies need. That's why they become obese. It's that simple.
Yes, everybody knows that. The question is what are all the things that lead people to ingest more calories than they need, and if certain kinds of pollution may play a part in that.
The more cars are around, the less children are walking.
When a child has to walk or bike to school it is less likely to be obese than when it's driven by soccer mom in her SUV.
studies show people who fart directly into your mouth are more likely to win the lottery
especially if its a big wet fart that splatters all over your big fat lips
Parents don''t say 'No' when their children scream 'But I want to go to McDonald's!' whilst throwing a tantrum. That's the reason.
Guess there are no Fat kids outside of Cities. wow.... this shouldn't even be on this site. its like saying typing on your keyboard has been linked to D*ck Shrinkage. lol
Europe has a fascination with diesel due to taxation benefits. There's a lot more diesel used in Europe vs USA. Yet US kids are fatter.
Once one takes in more calories than the body needs, the [human] body stores any extra calories as fat. This fat is what we see and draw the conclusion that one is obese.
Let anyone challenge me on this.
Caloric retention is variable. Individuals with the same diet can have very different weight (and the composition of that weight) because of many biological factors relating to cell type prioritizing and thoroughness of food breakdown. This much is scientifically accepted, but much like the discovery that diabetes is a pancreatic malfunction and the existence of bacterial ulcers, people who learned a simple explanation in 4th grade believe their misunderstanding to be absolute truth and reject all later discoveries.
I advise all my children not to eat anything that comes out of the exhaust pipe of a car.
"That's the way to do it" - Punch
It is also not hard to think of likely causal connections either: areas with high air pollution are either likely to be poorer and/or have more traffic which will mean less playing outside and fewer trips to the grocery store making processed foods with longer shelf lives more appealing than fresh produce. I wish journals would remember that correlation != causation and refuse to publish crap like this without actual evidence of cause.
In first world countries these "scientists" might think this is plausible but as soon as you include a bunch of third world countries this is BS.
You can go to highly polluted cities in third world counties and guess what, the vast majority of all people are skinny. You can go to the countryside both polluted and not polluted and guess what, most people are skinny.
And these people could over-indulge on food if they wanted to, they just don't.
No, the answer is social acceptance (how "okay" is it to be fat in this society), behavior (binge eating on McDonalds is normal, for example), and what foods are being consumed (mayonnaise and cheeseburgers, vs short grain brown rice, sizzle peppers, and a small portion of steak, or millions of other comparisons).
Yeah, like conservation of energy. What a dumb idea.
If caloric retention is in fact variable, then those diet studies haven't properly accounted for caloric inputs and caloric outputs. Any claims to the contrary would falsify a very solid theory and earn a Nobel prize.
captcha: OMG you're fat
Exactly. Everyone know how you get fat, this looks at why
It could be Chemical X inhibits vitamin intake, causing people to eat more to compensate. Chemical X might cause depression, which in a population can lead to overeating as a mechanism to cope. Chemical X might inhibit the ability to feel full. Chemical X could make people less inclined to exercise.
Heck, it could be "cars produce Chemical X, more cars more Chemical X, more cars the less parents let their kids out to play, less play time early in life could lead to obesity later in life.
Having evidence of correlation and handwaving it away as calorie consumption doesn't do anybody any favors.
To listen to some, it's completely impossible that there are any biological or epidemiological reasons. They have studied all of the possible combinations of factors and ruled out anything other than a lack of discipline and self-control. We're just waiting for them to present evidence for this sudden shift in human psychology.
false model, since manure burns. all calories taken in are not used. since all calories not used, some food types might cause obsesity compared to others.
high fat high protein diet == low obsesity
high carb diet == obsesity

....because Nairobi street kids are famously obese?
"...The scientists took a series of other factors into account, including gender, ethnicity and parental education, and think it is unlikely that variations in diet could explain the strong link found...."
I'd suspect confounding factors like poverty, urbanization, and THOSE impacts on peoples' diets in the early years of life (or the diets of their nursing mothers) before I'd point a finger at the trucks driving by.
Don't get me wrong, I think early childhood development is probably stunted by particulates, NOx, etc *particularly* from diesel vehicles, but I think this study is merely finding correlation.
-Styopa
Scientists are losing their credibility with every report they put out.
The subjects are ingesting more calories than their bodies need. That's why they become obese. It's that simple.
This is just stating the obvious while explaining nothing.
Of course fat people eat more. But WHY do some people eat more than others? And why have obesity rates TRIPLED since the 1980s? And why is there a huge disparity in obesity rates between different income levels and different ethnicities? And why have obesity rates soared in some countries, while barely changing in others?
Meaningless tautologies like "people are fat because they eat more" explains none of that.
I read giving kids sugary drinks counteracts the effect of nitrogen dioxide.
It's a pretty common observation that many kids don't get off their fat asses and go play outside anymore. When your gluttonously indulgent kid's face is stuck in a game or computer screen every free waking moment or else they can't stand to be alive or people can't stand to be around them then the result is fairly predictable.
People and kids are obese because our food supply has become contaminated with huge amounts of sugar and carbs. A huge number of American's are now diabetic as a result. The drug, foods, and medical corporations are all in cahoots on this. That there is no outcry from the government is in my opinion, because the corps are running the show.. https://www.cdc.gov/media/rele...
Have you fscked your local propeller head today?
But over and over again science is finding that people's decisions aren't really their own in this area (and others).
If anything we're still swinging too hard towards the Personal accountability direction. Other countries with more social safety and support networks consistently out score us on every metric (except number of billionaires, we're tops there). It's puritanicalism, and it's never worked. Any more than trickle down economics does.

Manure burns because cellulose is very hard to digest.
high fat high protein diet == low obsesity
That's mostly because people eat less on such a diet. It makes you feel full for longer. Try eating a block of cheese, and then watch your poop the next day. Most likely it is perfectly normal, indicating that pretty much all of the fat was absorbed.
high carb diet == obsesity
Also not true. Plenty of people around the world eat (or ate) a high carb diet and are perfectly lean.
The things that make you fat are usually foods that are both sweet and fat. Try eating a bowl of plain sugar. It's disgusting. Try eating a bowl of plain cream. Not very appetizing either. Now mix them together, chill them, and you have ice cream. All of a sudden, you can eat both bowls.
Wow. You can always tell when it's an election year.
Oliver's law of assumed responsibility: If you're seen fixing it, you will be blamed for breaking it.
Of course fat people eat more.
Not awlays. Be careful here...
But WHY do some people eat more than others?
Because food is cheaper than ever before...
And why have obesity rates TRIPLED since the 1980s?
See above; plus the increased drinking of sugars and sodas since the 80s.
And why is there a huge disparity in obesity rates between different income levels and different ethnicities?
All of the above; plus, it depends on where these ethnic people are found. Black Africans in East Africa are of the "thin build." Their "cohorts" in the USA for example are primarily obese. Sad but true. Those in Africa consume less to no processed foods, eat generally less and are more physically active.
And why have obesity rates soared in some countries, while barely changing in others?
It's soared in "rich" countries because of the above and the fact that these days, people do not necessarily burn more calories while working. Automation has a lot to do with what we see.
woah woah woah slow down you monster bigot! just because theres irrefutable evidence doesn't make it true!
Tell me how often you see kids in vehicles, with the WINDOWS DOWN. Probably almost never, because mommy is on the phone and doesn't want the noise LOL.
It appears they didn't actually check diet. Another thing, the closer you live to "convenient" roads and shops, the less exercise you may be likely to get. People in Japan and most of Europe seem much trimmer than Americans because they use public transportation more. With public transportation, you still have to walk the first and last mile (roughly) to get to and from the mode of transportation. They walk more, including children.
Table-ized A.I.
How about Universal Basic Food instead of UBI. You get an allocation of good healthy food for free. Any food you wish to purchase beyond your UBF is extremely expensive.
There is this perpetual challenge that humans have to combat the desire to believe or need that problems only have one cause.
It's emotional and intellectual. Consider yourself an excellent example of the problem.
"Old man yells at systemd"
thats all folks
Yeah, science found that other people are forcing you to eat. Sure it did.
This article is crap. I've been to places where the diesel fumes in the air are only slightly less anoying than the smell of raw sewage and burning garbage. Places where the particulate count on a good day makes Los Angeles air seem absolutely pristine in comparison. This article would have us believe that their obesity rates should be off the charts, and yet the number of fat people I saw in any given day could be counted on the fingers of one hand. Why? People eat less, and exercise more. But that's not really their decision, right? It's all just fucking magic.
And not all those Big Macs you've been eating all day long while sitting in the same spot on your couch playing with your smartphone instead of doing actual exercise.
I would agree with you except I already know that after pregnancy women can experience varying side effects that cause issues with weight gain and loss out side of the expected results of diet and exercise. Although that has nothing to do with childhood obesity conditions like gastro intestinal hyperpermeability and hypothyroidism do exist.
Many individual risk factors for BMI growth, such as asthma and other respiratory conditions, individual and neighborhood/community level socio-economic indicators, smoking (both personal and second hand smoke), and numerous built environment variables around the home and school, were also tested as confounders... final model was developed by including a set of basic design variables (race, ethnicity, gender, cohort of enrollment, and community) and any other additional confounders. Confounders were selected if they had a bivariate association with the outcome (p 0.2) and they changed the effect of interest – traffic density – by at least 10% in either of the gender specific effects at each buffer distance (i.e., 150, 300, and 500 m). ... Given what is known about the association between lower socioeconomic position and higher traffic exposures in California (Green, et al., 2004), some of the effects observed here may be confounded by dietary variables that are also associated with lower socioeconomic status, such as sugar and fats (Drewnowski, 2007). Our models did control extensively for socioeconomic status in the home and neighborhood, so although possible, it is unlikely that residual confounding relating to social status is present in the models. Finally, indicators of physical activity available to us for this cohort (participation in team sports and time spent outside) did not explain the effect of traffic,
nope, you can eat a diet of no cellulose and feces will still burn.
plain cream? I eat greek yogurt with no flavoring.
nope, historically people did NOT eat a high carb diet, look it up. agriculture with grains are a recent thing.
as for eating a bowl of plain sugar, plenty of people essentially are doing that with "breakfast cereal", junk food snacks (that go to sugar), soda pop (liquid sugar with flavoring), etc.
running your blood sugar high will cause insulin resistance and obesity
Correlation does not indicate CAUSATION.
It's junk science like this that helps fuel the anti-science sentiment that's all too popular these days...
Because food is cheaper than ever before...
Yet obesity is worst in people that can afford the least food. And obesity rates have soared in some poor countries with income levels far below the level where they were when obesity started to climb in the US. And obesity failed to rise in some countries where food became dramatically more affordable.
The big decline in food prices happened in the 1950s, 60s, and 70s. Yet there was a negligible increase in obesity during that time. Then in the early 1980s, obesity rates began to climb dramatically.
Black Africans in East Africa are of the "thin build." Their "cohorts" in the USA for example are primarily obese.
Very few African Americans are of East African descent. Barack Obama is a rare exception. He, like most East-African-Americans, is skinny.
It's soared in "rich" countries
Obesity soared in some rich countries, but not in others. It also soared in some poor countries, but not in others.
And why is there a huge disparity in obesity rates between different income levels and different ethnicities?
This surprises some people, but there is no reason to expect the statistics to be the same across the board when you group people by arbitrary criteria.
Even if you had an answer it doesn't mean that equalizing obesity rates becomes a laudable goal. (An actual good goal is reducing obesity across the board.)
You can keep digging until you find the answer you really want, that society is to blame and obese people are powerless to do anything about it.
sedentary lifestyles cause obesity. You know, playing video games and watching tv all day, that causes obesity. in general, lack of exercise aka sedentary lifestyle!
Your anecdote about "how many fat people you see" are as moronic and worthless to as your everyday nazi faggot dance. You don't matter, your word means nothing. No one will ever use anything you say as a factor in any decision.
Nope, not that simple:
https://www.scientificamerican...
Same diet, different gut bacteria - one group gets fat, the other stays lean.
The old (calories in - calories burned) model is overly simplistic and ignores a couple decades of research that shows that obesity is more than just a willpower deficit.
It's due to people consuming that crap
If that was really true Faux News viewers would be the fattest of the fat.
Yet CNN viewers like Michael Moore and Rosie Odonald run contrary to your theory... Imagine that...

Might as well try to ban water because kids drown in it.
Have gnu, will travel.
Some places I visited in France (where most all cars on the road were Diesel) were... well gross. They are having big problems from the small particles in diesel exhaust and are moving to all gasoline engines in the near future (Why not electric? I think there industry is to far behind and missed out on rare earths.)
But anyway yeah lots and lots of Diesel cars and yet.... NO FAT PEOPLE.
We need more Pirates to stave off global warming!
Most notably, obesity did not increase in East Asian countries such as Japan and Korea. The reason here is because the cultures of these countries hate fat people. Parents and schoolmates relentlessly tease them. Japan has increased fines/fees/insurance premiums for companies with overweight employees.
East Africans are skinny because East Africa is poor and can't afford a sedentary life. The West is fat because we're rich, sedentary, and don't fat shame like the East Asians.
My younger sister is fat because she eats too much. I'm not because I eat less. My other sister was fat until stopped eating so much.
It's that simple.
I don't disagree with your premise. We have way too much convenient, easily accessible (and tasty!) food that has a lot of carbs and sugar in it.
What I have a problem with is the idea it's government's job to step in, playing the role of parent, to force people to make "better food choices" by punishing people offering the less healthy options that are so popular.
Heck, I know I eat way too much sugary and processed food, myself. But I wouldn't be happy at all if my government outlawed the stuff I'm buying or placed big restrictions (likely high taxes) on it. I know the reasons why I tend to choose these things, and a lot comes down to lack of free time. If you insist on only eating fresh foods, you run into the age-old problem that they don't keep well. Just try putting a tossed salad in the fridge for a couple of days and then take it back out to eat it. Doesn't look so appetizing anymore with the lettuce starting to turn brown around its edges, the tomatoes getting mushy, and water starting to seep out of the veggies and into a little pool at the bottom of the salad bowl. America doesn't really have a culture like some European countries where you can wake up, walk down the steps and outside, to buy some fresh bread or other items to make breakfast with from a street vendor right around the corner.
I even live in a fairly rural area where I can drive a few miles and stop by a fresh produce stand that one of the local farmers has set up. I occasionally get some ears or corn or what-not from them. But still, my work and family life is usually way too hectic for me to make time for that. Most of the time, I'm driving quickly past them to pick up a kid that had to stay late after class and can't get a bus ride home, or running to one of 4 offices to fix the latest computer or tech crisis one of them is having..... things like that.
To fix this, you'd really need a big cultural shift in America.... a change in attitude about what's expected of people in their daily work life and a change in the way people prefer to buy their groceries. Right now? It is what it is, so I just settle for eating healthy when it's viable and being thankful for the technology that allows frozen dinners and canned food that stays good until you're ready to eat it.
Not for long, thanks to that lovely Mr Farage. He's always so nicely turned out, isn't he?

and I'm not alone. Also, smog days (if you don't know, these are days you're not supposed to go outside to play because the smog is bad enough to impact long term health) have been increasing, not decreasing.
We've lowered the rate at which things get worse, but we haven't stopped making them worse. I'll take that over doing nothing, but I'd kill for functional public transportation (and no, sacrificing 4 hours out of my day is not "function".

Sugar was the a wonder food. Sugared cereals originated there. There were little or no diet drinks and no Atkins or Paleo diets. The big upswing in obesity started in the 80s.
Hi! I make Firefox Plug-ins. Check 'em out @ https://addons.mozilla.org/en-US/firefox/addon/youtube-mp3-podcaster/
just like certain groups are more likely to get diabetes than others. Diabetes is pretty rampant in native american tribes. There's a lot of us with some amount of native american genetics in our blood. Obviously the excessive sitting we do, compared to 50yrs ago, only exacerbates a preexisting condition.
In a similar vein to the subject article, we've had evidence that "social deprivation" is responsible for obesity. Now social deprivation tends to mean poor housing, which collects around (among other place) city centres, roads and junctions and the like, polluted places. (If you can afford it, you live in the country, or overlooking a park or river). So there's a possible reverse causality for a correlation between obesity and pollution. There's far too much of this bad science based on misusing statistics.
So what? Recorded history is only 5,000 years and agriculture 12,000. Tiny amount of the 200,000 years of modern humans have been around. Not what we're supposed to be eating.
was of some fat kid in the back seat of a car letting one rip so bad, you could see the windows vibrate.
It's absolutely not meaningless to continue to state that excess caloric intake will result in obesity.
Why? Because some people WILL eventually disassociate excess caloric intake with obesity as they search for the answers to the questions you've provided.
For example, people will say their obesity is ONLY due to their genetics.
People tend to support things that absolve their actions/responsibility.
Please note that it is _not_ the food industry producing over-sweetened products loaded with corn-based sweeteners and the side issue that the SAD (Standard American Diet) causes diabetics and consequently Alzheimer's!
So, blaming something else seems to do the trick!
