摘要

本研究的目的是描述在 COVID-19 大流行期间,美国成年人在可持续饮食行为(支持环境、经济和身体健康的饮食行为)方面的变化,并研究不同种族/民族和社会经济地位的个体在饮食行为变化方面的差异。因此,我们在 2021 年 4 月开展了一项横断面在线调查研究(样本数 = 1,488,平均年龄 = 42.7 (SD = 12.6)),受访者均为密歇根大学医疗系统密歇根医学中心的门诊病人。为确保样本的多样性,设定了入学配额--三分之一的参与者为非洲裔美国人/黑人,三分之一为西班牙裔/拉丁美洲人,三分之一为白人,三分之一为低收入者。与 COVID-19 大流行一年前相比,参与者报告了更多支持可持续饮食的行为。在生态和经济可持续行为方面尤其如此,如减少去杂货店的次数、更多地使用家庭杂货配送服务、更多地在家做饭以及更多食用健康食品。并不是所有的行为改变都促进了可持续食品体系的发展,即农贸市场和社区支持农业(CSA)的使用率有所下降。与非裔美国人/黑人、西班牙裔/拉丁美洲人和低收入人群相比,白人和高收入人群更有可能在大流行期间采取生态和经济上可持续的饮食行为。与此同时,非裔美国人/黑人参与者的身体健康可持续饮食行为大幅增加。为了支持更多的人继续参与可持续饮食,应优先考虑增加公共交通、限制消费者购买杂货的频率、增加在家工作的选择以及改善低收入人群的交通条件等政策。

Changing sustainable diet behaviours during the COVID-19 Pandemic: inequitable outcomes across a sociodemographically diverse sample of adults.

The objective of this study was to describe changes in sustainable dietary behaviours (those that support environmental, economic, and physical health) among a sample of US adults during the COVID-19 pandemic and to examine differences in changes by individuals' race/ethnicity and socioeconomic status. Therefore, a cross-sectional online survey study was conducted in April 2021 (N = 1,488, mean age = 42.7 (SD = 12.6)) receiving outpatient care from Michigan Medicine, the University of Michigan health system. Enrolment quotas were established to ensure a diverse sample-one-third of participants identified as African American/Black, one-third Hispanic/Latino, one-third White, and one-third low-income. Participants reported engaging in more behaviours that are supportive of a sustainable diet one year into the COVID-19 pandemic compared to before. This is particularly true regarding ecologically and economically sustaining behaviours such as taking fewer trips to the grocery store, increased use of home grocery delivery, increased cooking at home, and greater consumption of healthy foods. Not all behaviour changes promoted sustainable food systems; namely, the use of farmer's markets and Community Supported Agriculture (CSAs) declined. White and high-income participants were more likely than African American/Black, Hispanic/Latino, and low-income individuals to engage in ecologically and economically sustainable dietary behaviours during the pandemic. Meanwhile, African American/Black participants reported large increases in physical health sustainable dietary behaviours. To support the continuation of greater engagement with sustainable diets, policies that increase access to public transportation, limit the frequency with which consumers have groceries delivered, increase work-from-home options, and improve access for low-income populations should be prioritised.
