Systematic reviews investigating associations between objective measures of the food environment and dietary behaviours or health outcomes have not established a consistent evidence base. The present paper aims to synthesise qualitative evidence regarding the influence of local food environments on food and purchasing behaviours.
A systematic review in the form of a qualitative thematic synthesis.
Urban localities.
Adults.
Four analytic themes were identified from the review including community and consumer nutrition environments, other environmental factors and individual coping strategies for shopping and purchasing decisions. Availability, accessibility and affordability were consistently identified as key determinants of store choice and purchasing behaviours that often result in less healthy food choices within community nutrition environments. Food availability, quality and food store characteristics within consumer nutrition environments also greatly influenced in-store purchases. Individuals used a range of coping strategies in both the community and consumer nutrition environments to make optimal purchasing decisions, often within the context of financial constraints.
Findings from the current review add depth and scope to quantitative literature and can guide ongoing theory, interventions and policy development in food environment research. There is a need to investigate contextual influences within food environments as well as individual and household socio-economic characteristics that contribute to the differing use of and views towards local food environments. Greater emphasis on how individual and environmental factors interact in the food environment field will be key to developing stronger understanding of how environments can support and promote healthier food choices.
系统评价调查客观食物环境指标与饮食行为或健康结果之间的关系，尚未建立一致的证据基础。本研究旨在综合定性证据，探讨当地食物环境对食物和购买行为的影响。

本研究从综述中确定了四个分析主题，包括社区和消费者营养环境、其他环境因素以及个人购物和购买决策的应对策略。可获得性、可及性和可负担性被一致认为是商店选择和购买行为的关键决定因素，这些行为往往导致社区营养环境中更不健康的食物选择。消费者营养环境中的食物供应、质量和食品店特征也极大地影响了店内购买。个人在社区和消费者营养环境中使用了一系列应对策略来做出最佳购买决策，通常是在经济限制的情况下。
本综述的结果加深和扩展了定量文献的范围，并为食物环境研究中的理论、干预和政策制定提供了指导。需要调查食物环境中的背景影响，以及个人和家庭社会经济特征，这些因素会影响对当地食物环境的不同使用和看法。在食物环境领域，更加强调个人和环境因素的相互作用，将是更好地理解环境如何支持和促进更健康的食物选择的关键。
