If you're curious about the health of citizens in your area, you may not have to look any farther than your mailbox. Recent research suggests that ZIP codes are a fairly accurate way to predict obesity rates. Two separate studies -- one in Seattle and one in New York -- found that geographical location and the associated socioeconomic status of those neighborhoods could easily be correlated to weight. As the prices of average homes climbed, rates of obesity fell and the opposite was also found to be true.
One theory experts have is that in poorer areas, residents are more likely to have access to and buy sweet and high-fat foods -- often the cheapest on the shelves. It's an intriguing study, and MSNBC
has an interview with the lead author here.
