THE ASSOCIATION BETWEEN URBAN SPRAWL AND OBESITY: IS IT A TWO‐WAY STREET?
研究了城市发展模式与肥胖之间的双向因果关系，发现搬到更密集地区的人体重下降，而高BMI的人更可能选择低密度蔓延地区。
ABSTRACT We empirically examine the relationship between obesity and urban development patterns where individuals reside. Previous analyses treat urban form as exogenous to weight, and find higher body mass indices (BMI) among residents of areas with sprawl patterns of development. Using samples of recent movers, we find that the causality runs in both directions. Individuals who move to denser locations lose weight. As well, BMI is a determinant of the choice of a dense or sprawling location. In sum, while moving to a dense area results in weight loss, such locations are unlikely to be selected by individuals with high BMI.
