研究当地食物环境与肥胖之间的关系，并评估所审查研究的质量。系统的关键词搜索确定了来自美国和加拿大的研究，这些研究评估了肥胖与当地食品环境的关系。我们应用了基于设计、曝光和结果测量以及分析的质量度量。我们确定了代表65个队列的71项研究。总体而言，研究质量较低; 60项研究为横断面研究。食品出口的可用性和肥胖之间的关联主要是零。在非零关联中，我们看到了超市可用性与肥胖之间的负相关趋势（22负，4正，67空）和快餐与肥胖之间的直接关联（29正，6负，71空）。我们发现快餐供应与低收入儿童肥胖之间存在直接联系（12例阳性，7例无效）。包括多个食品店在内的指数与成人肥胖最相关（18个预期，1个非预期，17个无效）。仅限于更高质量的研究并不影响结果。尽管有大量的研究，我们发现当地食品环境和肥胖之间的关联的证据有限。由于现有研究的质量较低，应谨慎解释主要为零的相关性。
To examine the relationship between local food environments and obesity and assess the quality of studies reviewed. Systematic keyword searches identified studies from US and Canada that assessed the relationship of obesity to local food environments. We applied a quality metric based on design, exposure and outcome measurement, and analysis. We identified 71 studies representing 65 cohorts. Overall, study quality was low; 60 studies were cross-sectional. Associations between food outlet availability and obesity were predominantly null. Among non-null associations, we saw a trend toward inverse associations between supermarket availability and obesity (22 negative, 4 positive, 67 null) and direct associations between fast food and obesity (29 positive, 6 negative, 71 null) in adults. We saw direct associations between fast food availability and obesity in lower income children (12 positive, 7 null). Indices including multiple food outlets were most consistently associated with obesity in adults (18 expected, 1 not expected, 17 null). Limiting to higher quality studies did not affect results. Despite the large number of studies, we found limited evidence for associations between local food environments and obesity. The predominantly null associations should be interpreted cautiously due to the low quality of available studies.
