Disparities in neighborhood food access are well documented, but little research exists on how shocks influence such disparities. We examined neighborhood food access in New Orleans at 3 time points: before Hurricane Katrina (2004-2005), in 2007, and in 2009. We combined existing directories with on-the-ground verification and geographic information system mapping to assess supermarket counts in the entire city. Existing disparities for African American neighborhoods worsened after the storm. Although improvements have been made, by 2009 disparities were no better than prestorm levels.
社区食品可及性方面的差异有大量记录，但关于冲击如何影响这种差异的研究甚少。我们在三个时间点检查了新奥尔良的社区食品可及性：卡特里娜飓风之前（2004-2005 年）、2007 年和 2009 年。我们将现有的目录与实地核查和地理信息系统制图相结合，以评估整个城市的超市数量。风暴后，非裔美国人社区的现有差异恶化。尽管已经取得了一些进展，但到 2009 年，差异仍不如风暴前的水平。
