Can better urban planning make us healthier? - CSMonitor.com
Matthew Turner and co-authors have written an under-appreciated paper that was published in the Journal of Urban Economics. Here is the abstract of their paper titled “Fat City”:
”
“We study the relationship between urban sprawl and obesity. Using data that tracks individuals over time, we find no evidence that urban sprawl causes obesity. We show that previous findings of a positive relationship most likely reflect a failure to properly control for the fact the individuals who are more likely to be obese choose to live in more sprawling neighborhoods. Our results indicate that current interest in changing the built environment to counter the rise in obesity is misguided.”
Intuitively, Turner estimates a fixed effects regression using panel data where he tracks the same person over time for people who move from the center city to the suburbs or vice versa. If sprawl makes us fat, then the average person who moves from the center to the suburbs should be gaining more weight over time than the people who never leave the center city or never leave the suburbs. Turner rejects this hypothesis.
So, there is plenty of work to be done here but it remains an open question of how urban form affects our behavior. I’ve been especially interested in this question focused on our carbon footprint as a function of urban form.
Patrick Hetzner tried diets and exercise, just about everything short of stomach stapling to lose weight. Nothing worked. Five months ago he tried something new: a stomach pacemaker that curbed his appetite. Since having it implanted, Hetzner, a 20-year-old Munich mailman, has knocked off more than 10 kilos (22 pounds) from his earlier weight of 104 kilos (229 pounds). Hetzner got the device as part of a clinical trial. Since being approved by Britain last month, the device is available for sale across the European Union. It works a bit like a cardiac pacemaker, and consists of a stimulator and a sensor surgically implanted onto the stomach. The stimulator sends out electrical pulses meant to trick the stomach and brain into thinking the body is full. Hetzner said the pulses kick in a few minutes after he starts eating or drinking. He said they make him feel full after finishing about half the amount of food he would normally eat.
“Earth Day is a good opportunity to remember the tremendous discrepancies in who has access to fresh fruits and vegetables — and thus, who has the luxury of eating a healthy, balanced diet — in this country. My fellow bloggers and I have written extensively about so-called “food deserts,” where the number of grocery stores are dramatically insufficient for the number of residents. Too often, people in these neighborhoods rely on corner stores, where a bag of Doritos is cheap and available and a container of strawberries may not fit either criteria. As a result, federal, state and local governments have pushed to make healthy food more accessible. It’s a major part of Michelle Obama’s “Let’s Move” anti-obesity initiative, and her husband’s proposed budget for next year would dedicate $400 million to bringing fresh food to corner stores. But such efforts don’t do much good if the produce that makes it to poor neighborhoods is close to spoiling or has the potential to make people sick. A new study from Drexel University researchers published in the American Journal of Preventive Medicine shows that when stores in poor neighborhoods do get fresh produce, it poses both of those risks to buyers. After buying salad, strawberries, cucumbers and watermelon repeatedly over 15 months in the Philadelphia area, the scientists found that mold, microorganisms and bacteria were all more likely to be present on produce purchased from stores in poor neighborhoods than in wealthier ones. In other words, if you are a poor Philadelphian buying fruits and vegetables in your own neighborhood, chances are your produce will spoil faster and may give you food poisoning. How appetizing.”

Yet another obstacle to getting fresh food into underserved neighborhoods.
