The New Obesity Map

Boy this study had legs.

Researchers at the University of Alberta did a study whereby they mapped Canadian obesity rates in relation with fast food restaurant density.

What they found was

"was actually a fairly strong relationship, a strong correlation between the two, that those cities that had higher obesity and overweight rates tended to have a higher density of at least the larger fast-food restaurant chains, so there were more restaurants per person in those cities".
The media loved it!

Best part of this whole business?

The quote by the study's author, Dr. Sean Cash, a fine young economist that I had the pleasure of meeting and chatting with a few years ago at an obesity think tank. When asked what to make of the study this was his quote,
"I wouldn't say our study proves anything"
You see, some cities with high densities of fast food outlets had low rates of obesity and some cities with low densities of fast food outlets had high rates of obesity. Moreover there are literally dozens if not hundreds of other variables that may have influenced the results and even if the relationship was solid, it doesn't answer the question of chicken or egg.

Gee, you sure wouldn't guess that from the headlines would you? Well maybe if you lived in Vancouver as the Dr. Freedhoff award for journalistic integrity goes out to one lonely newspaper, The Vancouver Sun. Here's their headline:
"'Obesity map' shows strong link to fast-food access; But study doesn't prove anything, creator says"
Don't move yet.
