全球定位系统正越来越多地用于客观评估与健康行为有关的人的移动模式。然而，详细介绍其在食品环境中应用的研究很少。本系统综述探讨了GPS在食品环境暴露及其对健康的潜在影响研究中的应用。根据初步范围界定工作，从4个电子数据库和参考文献列表中确定了纳入系统综述的已发表文章，并对其进行了评价和分析，最终纳入截止日期为2015年1月。包括的研究使用GPS来确定个人与食品店的位置，并将其与健康或饮食结果联系起来。他们根据一套质量标准进行评估。6项研究符合纳入标准，被评价为中等质量。较新的研究具有较高的质量分数。在食物环境中观察到的流动模式和饮食相关的结果之间的关联是模棱两可的。研究结果一致认为，传统的食物暴露措施高估了家庭食物环境的重要性。使用全球定位系统测量暴露于食品环境仍处于起步阶段，但具有很大的潜力。在开发和标准化用于评估暴露的方法方面存在相当大的差异和挑战。自2011年以来，只有6项研究使用GPS来量化暴露于食品环境。这些研究的质量一般都不高。所用的方法和技术有很大的差异和挑战。地理信息系统街区可能无法很好地代表基于全球定位系统数据的食品环境暴露。
Global Positioning Systems (GPS) are increasingly being used to objectively assess movement patterns of people related to health behaviours. However research detailing their application to the food environment is scarce. This systematic review examines the application of GPS in studies of exposure to food environments and their potential influences on health. Based on an initial scoping exercise, published articles to be included in the systematic review were identified from four electronic databases and reference lists and were appraised and analysed, the final cut-off date for inclusion being January 2015. Included studies used GPS to identify location of individuals in relation to food outlets and link that to health or diet outcomes. They were appraised against a set of quality criteria. Six studies met the inclusion criteria, which were appraised to be of moderate quality. Newer studies had a higher quality score. Associations between observed mobility patterns in the food environment and diet related outcomes were equivocal. Findings agreed that traditional food exposure measures overestimate the importance of the home food environment. The use of GPS to measure exposure to the food environment is still in its infancy yet holds much potential. There are considerable variations and challenges in developing and standardising the methods used to assess exposure. Since 2011 just 6 studies have been published employing GPS to quantify exposure to food environments. The studies were generally only of moderate quality. There were significant variations and challenges in the methods and techniques used. GIS neighbourhoods may not well represent food environment exposures based on GPS data.
