Sci rather wishes this study were done in mice, if only so she could write “the city mouse and the country mouse” in her title. But it was done in humans, which was really probably a good thing.
This post has some background. Sci was sitting around with her lab one day, shootin’ the breeze like you do when it’s Friday and science has you cross-eyed, and we were talking about going to meetings in exotic locales. We were talking about one especially large city, and one person in the group said “you know, what’s amazing about cities is how THIN everyone is”. And everyone in the group nodded sagely and said it was always shocking to go to large cities and realize how skinny everyone was.
But, being a scientist, Sci wondered…is this really true? Are people thinner in the city and thicker in the country, and if so, why? Is it just our perception, due to some cities featured on TV being full of starving artists and lots of plastic surgery? Is it universal? Is it just among the upper class? What about the urban poor? And is it due to all the walking, or is it just because of increased populations of starving artists?
And that’s not all. Sci just hopped up and moved to a new, Very Large City, and for the first week or so, my feet DEFINITELY noticed the walking increase. The blisters on my feet especially. Apparently every other female on the planet knew about those gel insoles to help you wear pretty shoes, but Sci apparently flunked that part of her “how to be a girl” exam.
So relationships between physical activity and obesity? Sci shot off an email to Travis of Obesity Panacea. Travis sent her a paper citation. Let’s do this.
Frank et al. “Obesity relationships with community design, physical activity, and time spent in cars” American Journal of Preventative Medicine, 2004.
(Put on your walking shoes! Sci hates those obligatory pictures of obese people next to pictures of people who are obviously models. This one is better.)
