UC Berkeley Study
Late last week, an article came out discussing a UC Berkeley study that links fast food proximity to obesity: how restaurants like McDonald’s being close to high schools contribute to obesity levels of ninth graders (high school freshman).
Interestingly, the major point seems to be that such fast food joints need to be one-tenth of a mile to the school, meaning — at least here in San Francisco — within one block. If the restaurants are a quarter to one-half mile away from the school, there doesn’t seem to be any correlation.
Further, the study points out that
…while just 7 percent of California’s high schools have a fast food restaurant within a tenth of a mile, 65 percent have one within half a mile. Schools within a tenth of a mile of a fast food restaurant have more Hispanic students, slightly more students eligible for free lunches, lower test scores, tend to be in poorer and urban neighborhoods - and have a higher than average incidence of obesity among their students
What does it mean?
From the article, we can infer that socio-economic class plays a role in determining whether a child will grow up to be obese.
The study seems to suggest that city planners, if they want to help combat obesity, should consider zoning requirements in the areas immediately surrounding schools.
Treating a Symptom
Of course, zoning requirements for fast food restaurants is just a small piece in the overall strategy to combat obesity.
A lot of low-income households have parents who need to work all day, and so children, both young and old, are left unsupervised, exposed to TV’s multitude of advertising on junk and fast foods, and thus most likely uneducated about healthy choices.
Thus, it’s really no surprise to hear that having a fast-food restaurant one block away from school will be a magnet for kids to get a quick “snack” after school, whether it be fries or a full-on “happy” meal. The meals are certainly not healthy, but they are fast, convenient, and cheap.
To really fight obesity, we’re really going to have to attack the issue on many fronts.
In future articles, we’ll take a look at other strategies.
