A poor diet has crucial impacts on individuals and society as a whole. In addition to individual preferences, there is evidence that people’s diet is related to their social, economic, and geographical environment, including their mobility context. However, few studies have an empirical, integrated perspective of these previous dimensions. This paper presents an empirical effort to understand people’s food purchasing and eating preferences concerning their mobility dynamics, social networks, habits, perceptions, activities, and sociodemographics, going beyond a static distance-based food supply perspective. The case study corresponds to the city of Concepción, Chile, using data that included nutrition, mobility, social networks, habits, perceptions, activities, and sociodemographics. The relationships between people’s eating and shopping patterns and these different contextual dimensions were analyzed through joint multivariate statistical modelling.

食品购买和饮食模式：评估人们的流动性、社交网络和健康饮食态度的作用


不良饮食对个人和整个社会有着至关重要的影响。除了个人偏好外，有证据表明人们的饮食与其社会、经济和地理环境（包括流动环境）有关。然而，很少有研究对这些先前的维度进行实证、综合的视角。本文提出了一项实证研究，旨在了解人们的食品购买和饮食偏好，涉及他们的流动动态、社交网络、习惯、观念、活动和社会人口统计学，超越了基于静态距离的食品供应视角。该案例研究对应于智利康塞普西翁市，使用的数据包括营养、流动性、社交网络、习惯、观念、活动和社会人口统计学。通过联合多元统计模型分析人们的饮食和购物模式与这些不同背景维度之间的关系。
