Asthma Risk Linked To Early TV Viewing
Ponca City, We love you writes "The number of children with asthma has been rising for many years. About 1 in 10 children in the UK develop asthma, compared with about 1 in 25 in the 1960s. The reason for this isn't clear, although several theories have been put forward such as keeping our homes cleaner, and having central heating and more soft furnishings where house dust mites can multiply. Now based on more than 3,000 children whose respiratory health was tracked from birth to 11.5 years of age, researchers have found a new correlation with young children who spend more than two hours glued to the TV every day doubling their subsequent risk of developing asthma. 'This study has shown for the first time a positive association between increased duration of reported TV viewing in early childhood and the development of asthma by 11.5 years of age in children with no symptoms of asthma in early childhood,' said the researchers, led by A. Sherriff, from the University of Glasgow. It's not clear exactly how sedentary behaviors like television watching are tied to asthma, but there is some evidence to suggest exercise and deep breaths that come with it stretch the smooth muscles in the airways, while lack of exercise may make the lungs overly sensitive. The results add asthma to a catalog of undesirable outcomes, including obesity, diabetes, smoking, and promiscuity, tied to TV viewing."
Wow, so promiscuity is now considered an undesirable outcome? Perhaps from a religious morals point of view...
Shit happens and it's usually caused by assholes
It's an interesting result that certainly warrants further study but IMHO everything about this study just screams "correlation is not causation".
What if healthier kids just enjoy playing outside more? What if healthier parents (who didn't have asthma themselves as children) encourage their kids to play outside more. What about kids in urban environments with high levels of air pollution who don't really have anywhere to go outside to play (without getting shot in a drive-by).

Make sure you hover over the comic...
Presumably (as far as Asthma goes) the same applies to sitting in front of computers/sitting playing handheld games like the DS. Though it would be interesting to know whether that carries the same correlations with the other undesirable outcomes.

In another scientific article researchers link filthy carpets in the living room to asthma, but for some reason that article never made the headlines...
100% of people who don't breath don't have Asthma.
I'm filthy stinking rich and have a REALLY nice sports car.
You know, most of the filthy rich sports car owners I know:
1) Don't sit round big noting themselves on Slashdot.
2) Don't refer to their sports car as a "really nice sports car", but rather something more specific like "a 1967 Jaguar E-type coupe".
I am prepared to believe that you're a smoker & obese.
My pics.
the other way to look at this is that kids with asthma spend time in front of the tv since running around outside may kill them
"Correlation does not imply causation" is said in every topic that has any type of statistics. So while this may have been the first post about it in this topic, its quite redundant.
The correlation coefficient is simply a tool.
What about sitting still in a desk at school for hours each day?
OK no seriously now WTF. There's not a day without a health news story talking about some weird correlation between two factors that are obviously not directly related. What's a researcher these days, someone who gathers a whole bunch of data, looks for all the statistical correlation they can find and publish a paper as soon as they find "something", without using an ounce of critical thinking? It surely is how it sounds like.
"So we took a whole bunch of people, alright, we asked them a whole bunch of random questions about their weight, their diet, their asthma, their TV watching habits, then we cross plotted them, let the computer program give us a correlation index and the one with the strongest correlation was asthma vs TV so we wrote a paper about it. As to the whyness of this correlation, meh, we don't really know, nor did we bother to establish a few hypothesises like "oh maybe it's due to socio-economic conditions i.e. poor people watch more TV and live in houses with asbestos hey let's try and find out", nah, we just care about writing a paper and making it buzz for all it's worth cause it's gonna look good on our CVs and you know it's going to work because people love senseless sensationalist drivel like "new research shows that learning to play the violin will make you live 6 years longer!" or "can eating pineapple make you gain IQ points?"."
You just got troll'd!
> I don't think that researchers understand the difference between causation and correlation.
Why is that ? Have you ever undertaken studies to become a researcher, perhaps at PhD or post-doc levels ? If you did and still believe this, then you should ask for your money back. Most such programs involve quite extensive theory behind how to calculate statistical association and correlation. Do you actually know anything on how this study was performed and how its findings was analyzed ?
Perhaps you do, but the tone of your comment leads me to think that you have no idea and just think the summary sounded too far-fetching for your liking.
Oh, I can't help quoting you because everything that you said rings true
"What's the point of promiscuity if it doesn't make babies?"
If you really need to ask this question, you are truly a Slashdotter.
