摘要：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.
