现有的研究表明，适合步行的环境可以防止体重增加，而庞大的社区可能会带来健康风险。使用卡特里娜飓风幸存者流离失所的前瞻性数据，我们提供了第一个自然的实验数据蔓延和身体质量指数（BMI）。该分析使用前瞻性收集的前（2003-2005）和飓风后（2006-2007）的数据，从卡特里娜飓风幸存者（风险）项目的280流离失所的卡特里娜飓风幸存者谁没有控制他们的邻里安置灾难后立即。县蔓延指数是一种标准化的建筑环境指标，用于预测随访时的BMI，并根据基线BMI和蔓延情况进行调整;飓风相关创伤;人口统计学和经济特征。卡特里娜飓风过后，新奥尔良地区8个县的受访者分散到76个县。在县蔓延指数上，蔓延平均增加了1.5个标准差（30个点）。在未校正的模型中，每增加1分，BMI增加约0.05 kg/m2（95%CI：0.01 - 0.08），在协变量校正后，这种关系没有减弱。我们发现，居住在一个庞大的县和较高的BMI之间的强有力的关联不太可能是由自我选择到社区，这表明，建筑环境可能会促进体重的变化。
Existing research suggests that walkable environments are protective against weight gain, while sprawling neighborhoods may pose health risks. Using prospective data on displaced Hurricane Katrina survivors, we provide the first natural experimental data on sprawl and body mass index (BMI). The analysis uses prospectively collected pre- (2003–2005) and post-hurricane (2006–2007) data from the Resilience in Survivors of Katrina (RISK) project on 280 displaced Hurricane Katrina survivors who had little control over their neighborhood placement immediately after the disaster. The county sprawl index, a standardized measure of built environment, was used to predict BMI at follow-up, adjusted for baseline BMI and sprawl; Hurricane-related trauma; and demographic and economic characteristics. Respondents from 8 New Orleans-area counties were dispersed to 76 counties post-Katrina. Sprawl increased by an average of 1.5 standard deviations (30 points) on the county sprawl index. Each one point increase in sprawl was associated with approximately .05 kg/m2 higher BMI in unadjusted models (95%CI: .01–.08), and the relationship was not attenuated after covariate adjustment. We find a robust association between residence in a sprawling county and higher BMI unlikely to be caused by self-selection into neighborhoods, suggesting that the built environment may foster changes in weight.
