健康的食品环境对公众健康至关重要。超市提供低价健康食品的途径因空间、社会经济地位和种族社区的不同而不同。这项研究考察了荷兰阿姆斯特丹的食物不平等现象。超市可达性是在100米空间分辨率的地理微观尺度上计算出来的，并与房地产价格和荷兰原住民的份额挂钩。曼恩-惠特尼测试和斯皮尔曼相关性被用来检验可获得性、房地产价格和每个地区的原住民比例之间的差异和联系。空间显式背景神经气体方法被用于数据聚类。结果显示，超市的准入差异有利于高房价地区和荷兰原住民比例较大的地区。相关性表明，低价地区和荷兰原住民比例较低的地区超市密度较低，但当检查超市的邻近程度和种类时，结果正好相反。聚集显示没有证据表明供应不足的地区。在获得健康食品方面的明显不平等无法得到证实。根据这一分析，政策制定者没有迫切需要干预超市的地理位置。(C)2017爱思唯尔有限公司。保留所有权利。
Healthy food environments are imperative for public health. Access to supermarkets that offer wholesome food products at low prices varies across space and over socioeconomic status and ethnic neighborhoods. This research examined food inequalities in Amsterdam, the Netherlands. Supermarket accessibility was calculated and linked to property prices and the share of native Dutch people on a geographic micro-scale with a spatial resolution of 100 meters. Mann-Whitney tests and Spearman correlations were used to test differences and associations between accessibility, property prices, and the share of natives per area. The spatially explicit contextual neural gas approach was used for data clustering. The results show access differences in supermarkets in favor of areas with high property prices and those areas with a large share of native Dutch people. The correlations indicate that low-priced areas and those with a low share of native Dutch people have a lower supermarket density, but the results are the opposite when proximity to and variety of supermarkets are examined. The clustering revealed no evidence of undersupplied areas. Pronounced inequalities in access to healthy food could not be confirmed. On the basis of this analysis, there is no urgent need for policymakers to intervene in the geographies of supermarkets. (C) 2017 Elsevier Ltd. All rights reserved.
