Does Sprawl Make Us Fat?
Ant writes "A Science News article talks about the relationship between city design and health. New cross-disciplinary research is exploring whether urban sprawl makes us soft, or whether people who don't like to exercise move to the sprawling suburbs, or some combination of both." From the article: "So far, the dozen strong studies that have probed the relationships among the urban environment, people's activity, and obesity have all agreed, says Ewing. 'Sprawling places have heavier people... There is evidence of an association between the built environment and obesity.' ... However, University of Toronto economist Matthew Turner charges that 'a lot of people out there don't like urban sprawl, and those people are trying to hijack the obesity epidemic to further the smart-growth agenda [and] change how cities look.' ... 'We're the only ones that have tried to distinguish between causation and sorting... and we find that it's sorting,' [says Turner]. 'The available facts do not support the conclusion that sprawling neighborhoods cause weight gain.'"
The objections quoted in TFS are debunked quite well in the linked science article. Additionally, research earlier this year shows teenagers living in sprawling suburbs were more than twice as likely to be overweight as teens in more compact urban areas
;-)
These kids have never moved, never had a choice about where they live and are still much fatter.
It's a no brainer really. Less walking opportunities = less energy expenditure = more stored energy (as well as eating crap on those long, boring car journeys to work/school to save on cooking time at home so you can sit in front of the idiot box).
Anyway, the failure of town planners is going to work out by itself in the end. As oil prices skyrocket & people in the suburbs grow fatter, the solution become obvious. Liposuction clinics combined with gas stations
There are shills on slashdot. Apparently, I'm one of them.
Let me try to sort this out:
YES, not having to walk around very much will make it more likely you won't get the exercise necessary not to be fat.
NO, it does not "cause" it (in the sense they want you to take it); you can still make the choice to exercise on your own, irrespective of how much you need to walk in a day for other purposes.
YES, there's probably a correlation between "how much people in this city have to walk" and "how fat they generally are" that persists after the appropriate controls.
NO, that's a bad, ad-hoc reason to fix urban sprawl. Urban sprawl is bad because it leads to time-wasting congestion and forces people to have to use cars, which sucks for anyone who can't or doesn't like to drive, and exposes people to the risk of energy price fluctuations unnecessarily. It also contributes to pollution. There, I just made a strong case why sprawl is bad, without resorting to being a health Nazi.
I'd like to plug my latest joural entry, which describes a way cities could transition gradually to less sprawl, without tedious regulation, government-run services, and invasive control over people's lives. In short: put up tolls heavy enough to clear congestion. This creates the financial incentives necessary for market-driven mass transit, which in turn makes denser development more economical and desirable to live in.
Apology to Ubuntu forum.
In many sprawling communities, walking past the driveway/subdivision is asking to die.
That's not hyperbole, but a basic consequence of planning that is downright hostile to anyone who isn't behind the wheel of a car. I don't believe cars should be eliminated, but car-dependance is a truly awful thing that I'm glad that I've been able to break free of...but I don't know for how long. The attitude of the Massachusetts Bay Transit Authority isn't friendly to mass transit. In the words of their last General Manager "the automobile won" and light rail is obsolete. Buses are the future, apparently. In the last few decades, automobile registrations in Boston have tripled as rail lines have been shut down or cut back dramatically in favor of surprise bustitution that suddenly becomes permanent.
It's depressing enough to see a new cookie-cutter car-dependant community rise up where a forest used to be, but it's even worse when a city with an excellent transit system that encourages people to ride the train then walk decides that it wants to be just like PinePointeAutumnPreserveRegistryReserveGrove Habitation Area #49485776893-B and compel people to pick up the bad habits of the suburbs.
that and civic design. Here in Houston I challenge you to ride a bike from point A to point B. There are no sidewalks, no back roads that go through, no bike lanes, what bike lanes that do exist are right next to fast moving over sized commercial loads that reguard that as a "vehicle sprawl" lane. Figure in unstable buisness environments that virtually guarantee that if you move close enough to work to walk/bike you will lose your job and be forced to work forty miles away.
When I lived in Phoenix, I rode my bike everywhere. Now that I live in Houston (one of the most sprawled cities in existance) I have gained massive amounts of weight, and regularly commuted 3+ hours a day.
The preceding post was not a Slashvertisement.
We all generally EAT TOO MUCH! Our guts are too big and so our hunger satisfaction signal is delayed. Working out and being active is good and all, but that's not the biggest part of what's wrong. It's WHAT we eat and how much of it we eat. That's why these stomach stapling operations are so remarkably effective. It's clearly not that these people have been working out too little, but that they have been eating too much. The solution is most simple and direct.
EAT LESS.
I'm kind of over-weight myself... I'm working on it... sorta. I never claimed the answer would be easy... I'm just identifying the problem for what it really is. Working out and being more active to "compensate" for the enormous amount of food we take in doesn't leave much time with family, friends or work. It's nearly impossible to work out enough to compensate for the diets most of us indulge in... just eat less.
Strangely enough, it is only in America that inner-cities are more dangerous than suburbs. In Australia and Europe, inner cities are seen as desirable places to live compared to the suburbs.
Maybe the original idea was to escape factories, but now the US has far less manufacturing capacity, so that isn't it anymore... what is it? Low gas prices (compared to the rest of the world) keep suburbs cheap, and black people tend to live in cities so it's undesirable to whites?
I come from Denmark but am staying in Minneapolis for a year. In Denmark you can walk to a nearby mall or at least a well-stocked convenience store pretty much no-matter where you live if you do not live too far from the central city. Where I live in Denmark I can *walk* to *everything* I need to do on a regular basis, and everything else is within convinient biking or bus distance. I don't have a car and I would have a use for a driver's license maybe once a year (when living in Denmark, that is).
Now, in Minneapolis, practically nothing is within walking distance no matter where you live and the bus system is an absolute pain to figure out even using their online planner. Not having a car around here is a serious social handicap, and it makes shopping a taxing experience, because everything is spread out within a huge area. I can't help but conclude that people around here actually *enjoy* spending alot of time in their cars, so that distance is an advantage to them.
Other than that, this is a very nice place, but for people who live here permanently, not having a car is simply not a workable option.

There are a number of reasons why Americans prefer to live in suburbs. White flight, as you mentioned, is one. Another is that most of us like our space. I grew up in a house where the back yard was totally secluded and we had a wooded lot to one side. Lots of privacy - you didn't look out your window right into someone else's. I'm in a dorm now. I love being near my friends, but the walls are paper thin. I can hear everything that goes on in the rooms beside me, and if it's loud enough, I can hear the speakers of the guy living across the building. A third reason is that since cities tend to grow outwards, houses in the suburbs are newer and nicer than inner city ones.
I live in a city that can be defined as the opposite of sprawl: Venice (Venezia), Italy. Buildings here are closer one to another than any place I know of. Some "calli" (pedestrian passages) are as narrow as half meter. Cars just don't enter the city beyond the parkings at the end of the bridge that connects it to the mainland, and even bikes are not allowed. You just walk. Every time your way intersects a canal, you have to go up and down the steps of a bridge. Because of the high density, the time spent moving from place to place in everyday business is not different from that in car-only cities. Remove the time spent looking for a parking place (a big problem in most Italian cities) and you have a net time advantage. You don't see many obese people in Venice and even elders citizens tend to be healthier than in other places. People meet and talk in the streets. Goods travel almost exclusively on water, on a network that is completely separate from that of persons. One of the downsides is a very uncomfortable environment for disabled people: wheelchairs weren't an option when the city was built!
