摘要

在过去十年中,中低收入国家(LMIC)的生计发生了巨大变化。这些变化与个人和家庭食物选择行为的变化同步发生。本范围综述旨在确定和描述生计变化可能影响低收入和中等收入国家食物选择行为的机制,包括与食物生产、获取、准备、分配和消费有关的行为。我们使用四个数据库进行了文献检索:PubMed、PsycInfo、AGRICOLA 和 Embase。如果研究衡量或关注生计的变化,描述或评估了至少一种食物选择行为的变化,并且关注低收入、中等收入国家的情况,则被纳入研究。不符合纳入标准或侧重于从低收入、中等收入国家向高收入国家移民的研究则被排除在外。通过数据库搜索和专家征集确定了 433 篇文章,其中 53 篇符合纳入标准。研究发现了生计变化影响食物选择的五种常见机制:职业、地点、时间、收入和社会关系。职业的变化改变了当地食物环境中食物的可获得性和可负担性与个人食物生产之间的平衡。地点、时间和收入的变化会影响到在哪里购买食物、购买什么类型的食物以及如何或在哪里制作食物。此外,社会关系和规范的改变也扩大了人们对食物的偏好,特别是在城市人口中。超加工食品消费的主要驱动因素包括生活导致的时间限制和可自由支配的收入增加。了解生计变化与食物选择之间的关系有助于为低收入和中等收入国家未来的循证行动提供信息,包括制定政策、计划和其他行动,以促进可持续的健康饮食和地球健康。

How Livelihood Change Affects Food Choice Behaviors in Low- and Middle-Income Countries: A Scoping Review

Livelihoods have changed dramatically over the past decade in low- and middle-income countries (LMIC). These shifts are happening in tandem with shifts in individual and household food choice behaviors. This scoping review aimed to identify and characterize mechanisms through which livelihood changes could affect food choice behaviors in LMIC, including behaviors relating to food production, acquisition, preparation, distribution, and consumption. A literature search was conducted using 4 databases: PubMed, PsycInfo, AGRICOLA, and Embase. The search was further enhanced by expert solicitations. Studies were included if they measured or focused on a livelihood change, described or assessed a change in ≥1 food choice behavior, and focused on LMIC. Studies were excluded if they focused on migration from LMIC to a high-income country. Of the 433 articles that were identified, 53 met the inclusion criteria. Five mechanisms of how livelihood change can affect food choice were identified: occupation, locality, time, income, and social relations. Changes in occupation altered the balance of the availability and affordability of foods in local food environments compared with individual food production. Changes in location, time use, and income influenced where food was purchased, what types of foods were acquired, and how or where foods were prepared. Additionally, changes in social relationships and norms led to expanded food preferences, particularly among urban populations. Time limitations and higher discretionary income were associated with consumption of ultraprocessed foods. Understanding the relationships between the changes in livelihood occuring in LMIC and food choices of households in these countries can inform the development of policies, programs, and other actions to promote sustainable healthy diets and planetary health.

期刊介绍: Advances in Nutrition (AN/Adv Nutr) publishes focused reviews on pivotal findings and recent research across all domains relevant to nutritional scientists and biomedical researchers. This encompasses nutrition-related research spanning biochemical, molecular, and genetic studies using experimental animal models, domestic animals, and human subjects. The journal also emphasizes clinical nutrition, epidemiology and public health, and nutrition education. Review articles concentrate on recent progress rather than broad historical developments. In addition to review articles, AN includes Perspectives, Letters to the Editor, and supplements. Supplement proposals require pre-approval by the editor before submission. The journal features reports and position papers from the American Society for Nutrition, summaries of major government and foundation reports, and Nutrient Information briefs providing crucial details about dietary requirements, food sources, deficiencies, and other essential nutrient information. All submissions with scientific content undergo peer review by the Editors or their designees prior to acceptance for publication.
