Living Near Shops and Transit Makes New Yorkers Less Fat

A new Columbia University study published in the American Journal of Health Promotion, yet again, links livable streets to improved public health. The study reports:

"There are relatively strong associations between built environment and Body Mass Index, even in population-dense New York City," said Andrew Rundle, Dr.P.H., lead study author and assistant professor of epidemiology at the Mailman School of Public Health at Columbia University Medical Center.

The study appears in the March/April issue of the American Journal of Health Promotion.

Researchers looked at data from 13,102 adults from New York City’s five boroughs.  The authors discovered that three characteristics of the city environment – living in areas with mixed residential and commercial uses, living near bus and subway stops and living in population-dense areas – were inversely associated with BMI levels.

For example, city dwellers living in areas evenly balanced between residences and commercial use had significantly lower BMIs compared to New Yorkers who lived in mostly residential or commercial areas.

"A mixture of commercial and residential land uses puts commercial facilities that you need for everyday living within walking distance," Rundle said. "You’re not going to get off the couch to walk to the corner store if there’s no corner store to walk to."

  • So, a rolling stone doesn’t gather moss?

    How do you keep your study’s numbers from being skewed by all the models?

  • Well, presumably, models living further from shops and transit would eventually have to cease being models due to body mass changes, so it should all come out in the wash…

  • Clarence

    BMIs are not extremely accurate. Anyone who does any amount of even light, healthy weight training has a skewed BMI. For example, my BMI puts me in the Obese range.

    But the study’s point is taken, and if you are using BMIs as a barometer for all groups I guess it all averages out.

  • P

    Or maybe it doesn’t even out… It could understate the weight difference if all of walkers are bulking up by carrying sacks of groceries 3 or 4 blocks and up a few flights of stairs.

  • Clarence

    Yup. In other words, New York City folks are probably in even better shape then their rivals in the study.

    I find it funny that when I visit folks outside of NYC and see them struggling and agonizing when bringing bags of groceries in to the house from the nearby car and then realize that many of us in NYC are lugging those same grocery bags 5 or 10 blocks home wihtout a respite!

    The article doesn’t say…. did they control for income? Seems to me that good transit and a healthily zoned neighbourhood results in higher demand and wealthier residents, who are less likely to be obese (is my understanding).

  • For those of you have not seen Clarence in the flesh, he has a very attractive, well sculpted body. If I just knew how to post pictures here…

    But Clarence, I do have to point out that you do not live that close to a train… and your closest stores are pizza shops.

    Aside from the controversy over the accuracy of BMI, the concept of a person who walks more being healthier than a person who drives more, absolutely makes sense to this girl who spent 9 years getting fat driving around Los Angeles only to move to NYC and lose it all in 6 months of walking around Manhattan!

  • Ian Turner

    BMI breaks when you look at any particular case, but it’s valid for statistical purposes; you’d expect the big-but-muscular people to counter out the gimpy-but-fat folks.

  • P

    What about the case we were discussing where New Yorkers are both losing fat by walking and gaining muscle by carrying their groceries?

    I don’t know if it is the case or not but it’s plausible. (Not that it seems to working out so well for me…)

  • It’s nice that someone thinks I am sculpted.

    I have to walk 8-10 blocks (usually) with my groceries.

    And I love pizza, thus my higher-than-it-would-look BMI.



More Evidence That Helmet Laws Don’t Work

If you want to increase cycling safety in your city, drop the helmet law and focus on getting more people– particularly women — on bikes, with street designs that offer separation from vehicle traffic. That’s the finding of a new study by researchers at the University of British Columbia [PDF] evaluating safety outcomes for cyclists across Canadian […]
