Disparities in diet quality persist in the U.S. Examining consumer food purchasing can provide unique insight into the nutritional inequities documented by race/ethnicity, socioeconomic status (SES), and geographic location (i.e., urban vs. rural). There remains limited understanding of how these three factors intersect to influence consumer food purchasing. This study aimed to summarize peer-reviewed scientific studies that provided an intersectional perspective on U.S. consumer food purchasing. Thirty-four studies were examined that presented objectively measured data on purchasing outcomes of interest (e.g., fruits, vegetables, salty snacks, sugar-sweetened beverages, Healthy Eating Index, etc.). All studies were of acceptable or high quality. Only six studies (17.6%) assessed consumer food purchases at the intersection of race/ethnicity, SES, or geographic location. Other studies evaluated racial/ethnic or SES differences in food purchasing or described the food and/or beverage purchases of a targeted population (example: low-income non-Hispanic Black households). No study assessed geographic differences in food or beverage purchases or examined purchases at the intersection of all three factors. Overall, this scoping review highlights the scarcity of literature on the role of intersectionality in consumer food and beverage purchasing and provides recommendations for future studies to grow this important area of research.
美国的饮食质量差异仍然存在。研究消费者的食品购买情况，可以深入了解种族/族裔、社会经济地位（SES）和地理位置（即城市与农村）记录的营养不平等现象。对于这三个因素如何相互交叉影响消费者的食品购买，人们的理解仍然有限。本研究旨在总结提供美国消费者食品购买情况的交叉视角的同行评审科学研究。研究共检查了 34 项研究，这些研究提供了有关购买意向（如水果、蔬菜、咸零食、含糖饮料、健康饮食指数等）的客观测量数据。所有研究的质量均为可接受或较高。只有 6 项研究（17.6%）评估了种族/族裔、SES 或地理位置交叉点的消费者食品购买情况。其他研究评估了食品购买方面的种族/族裔或 SES 差异，或描述了目标人群的食品和/或饮料购买情况（例如：低收入非西班牙裔黑人家庭）。没有研究评估食品或饮料购买方面的地理差异，也没有研究考察所有三个因素的交叉点的购买情况。总体而言，这项范围界定审查突出了关于交叉性在消费者食品和饮料购买中的作用的文献稀缺性，并为未来研究提供了建议，以促进这一重要研究领域的发展。
