Watch out if your best friend gets pudgy.
 
A new study suggests obesity can spread like an infectious disease and
that your odds of becoming obese are greater if your friends and family
put on weight.

By studying a social network of 12,067 people in a Boston suburb who have
been closely tracked for the past three decades, researchers found that
when one person became fat, those close to them gained, too.

The strongest influence was seen among friends no matter where they lived.
A person's chances of becoming obese went up 57 percent if a friend became
obese. In the closest friendships, the risk almost tripled. Among
siblings, the risk of obesity increased by 40 percent and 37 percent among
spouses.

"We were stunned to find that friends who are hundreds of miles away have
just as much impact on a person's weight status as friends who are right
next door," said co-author James Fowler of the University of California-
San Diego.

The researchers think it's more than just people with similar eating and
exercise habits hanging out together. Instead, it may be that having
relatives and friends who become obese changes one's idea of what is an
acceptable weight.

Despite their findings, the researchers said people should not sever their
relationships.

"There is a ton of research that suggest that having more friends makes
you healthier," Fowler said. "So the last thing that you want to do is get
rid of any of your friends."

The study was published in today's New England Journal of Medicine and
funded by the National Institute on Aging.

Researchers analyzed medical records of people in the Framingham Heart
Study, which has been following the health of residents of that Boston
suburb for more than a half century.

Obesity is a global public health problem. About 1.5 billion adults
worldwide are overweight, including more than 400 million who are obese.
Two-thirds of Americans are either overweight or obese.

According to the Centers for Disease Control, 27.8 percent of Hoosiers
were obese in 2006, compared to 19.9 percent in 1998.

Obesity is also tied to socio-economic status.  I wonder if there is
positive feedback loop...especially if you don't start out obese.

Interestingly, overweight girls for example are less likely to go to
college, which would support a feedback loop that sustains the socio
economic status.

There is a reason for that... Part of the pressure to lose weight is
peer pressure. Once in awhile, you just get sick to death of
self-deprivation if you are one of those that really has to fight to
lose weight and keep it off.

The pressure to continue working at it is relaxed when your best friend
gains weight.

I'd love to see them do a similar study in the work place where
co-workers weight is constantly fluctuating. I've seen it where I work!

If one person really loses a lot of weight and others hold that person
in high regard, you will see at least some weight loss in other
employees.

If and when that person fails, everybody gains it all back. I've been
working at the same place now for 20 years and have seen this cycle
countless times.

There is one girl in her 30's that had her 4th child about two years
ago. She weighed close to 300 lbs.

She is now down to about 180 and I swear she looks about 20 years
younger. Now if we could just get her mom to follow her daughters
example...

Bit of a "no shi% Sherlock" study I think. Much of what comes out of the
Framingham study (which is right down the road from me BTW) is very "no
duh" but that's what you often get with large epi studies such as this
one. Also works in reverse, leaner people tend to hang out with and or
effect other leaner people, etc. Also, a fat friend or family member
increases your chances of being fat (again, no duh) but a fat person
living next door does not, which again makes perfect sense as they are not
in their social network per se.

Lots of people that are trying to lose weight don't realize that
success may require that they start hanging around with different
people.  If you don't change your environment then chances are good
that you won't change your behavior either.

Pretty much the same with any large (or even moderate) change in
behavior, motivation, or outlook. If you stick with a group of drunks
and try to stay sober, it's much harder. Same with smoking and trying to
not smoke - though second-hand smoke does come into play.

Okay, the analogy's not perfect. But anyway, you get the gist.

That's why one of the worst things that a fat person can do is to
participate in ``support'' groups, online or in real life. For every
one person in such an environment who is motivated to do something,
there will be fifteen others who hate anyone who succeeds. They
secretly, perhaps unconsciously, want to maintain the status quo: to
stay the way they are /and/ sabotage everyone else who makes progress.

Moreover, you will just be wasting time listening to some losers
whine, complain, and keep exchanging the same misinformation that gets
them nowhere.

Support groups have a pretty good track record in real life.  In fact,
I think that you would be hard pressed to find something that works
better.  Of course, you need a support group that is actually
supportive, but that's a pretty low bar.

More on that in a bit.

Sounds a lot like misc.fitness.weights :).

Seriously though, I have been thinking a lot lately about the factors
in my life that made it possible to incorporate exercise into my life
on a long term basis.  I don't have workout partners or a gym
membership.  I don't play organized sports, and I don't compete (yet).
I have always assumed that I didn't have (or need) an exercise support
group.

However, looking over my exercise logs and my posting history it is
pretty clear that quite a bit of my success to this point is due to my
time spent on misc.fitness.weights.  I use misc.fitness.weights to
help me choose training protocols, to set goals, to pick out (and
purchase) equipment, etc.  What's more, I find that when I spend time
away from misc.fitness.weights my workouts tend to suffer as well.

Quite frankly, that last bit scares me a little.  I am hoping that the
reason for this correlation is that /life/ is simply intrudes on both
exercise and available USENET posting time, and so both suffer when I
get really busy.  On the other hand, I am afraid that I have to at
least consider the possibility that I even find misc.fitness.weights
to be *motivational*.  That's truly a dark thought.

If misc.fitness.weights can be considered a workable support group,
then just about anything qualifies :).  Like I said earlier, the bar
is set pretty darn low.  I imagine that as long as you steer clear of
the fat acceptance groups you should probably be just fine.  I, of
course, would suggest giving misc.fitness.weights a try, but my own
experiences have biased me against jogging and other forms of low
intensity cardio.

BTW, thanks misc.fitness.weights.  I appreciate the help.

Spoken (written) by a true genius & expert on what it is to be a "fat
person".

heh.

The bad habit of overeating and under exercising is not the only arena
where people with a bad habit in common develop social relationships.

For Example:
Alcoholics and or people who abuse alcohol tend to move within the
same social circles.

Pot heads flock together as do drugiies and assorted dope heads.
Thieves and hoodlums are more likely to have other thieves and
hoodlums among their circle of friends.

It shouldn't require possessing an advanced degree to take note of
this aspect of socialization.
