Food environment interactions after migration: a scoping review on low- and middle-income country immigrants in high-income countries

Objective: To map and characterise the interactions between the food environment and immigrant populations from low- and middle-income countries living in high-income countries. Design: A scoping review was carried out following the framework outlined by Arksey and O'Malley, as well as Levac et al. Peer-reviewed studies in English published between 2007 and 2021 were included. Two reviewers screened and selected the papers according to predefined inclusion criteria and reporting of results follows the PRISMA-ScR guidelines. A 'Best fit' framework synthesis was carried out using the Analysis Grid for Environments Linked to Obesity (ANGELO) framework. Setting: High-income countries. Participants: Immigrants from low- and middle-income countries. Results: A total of sixty-eight articles were included, primarily based in the USA, as well as Canada, Australia and Europe, with immigrants originating from five regions of the globe. The analysis identified three overarching themes that interconnected different aspects of the food environment in addition to the four themes of the ANGELO framework. They demonstrate that in valuing fresh, healthy and traditional foods, immigrants were compelled to surpass barriers in order to acquire these, though children's demands, low incomes, time scarcity and mobility influenced the healthiness of the foods acquired. Conclusion: This study brought together evidence on interactions between immigrant populations and the food environment. Immigrants attempted to access fresh, traditional, healthier food, though they faced structural and family-level barriers that impacted the healthiness of the food they acquired. Understanding the food environment and interactions therein is key to proposing interventions and policies that can potentially impact the most vulnerable.

Automated summary

This study aims to investigate and describe the interactions between immigrant populations from low- and middle-income countries and the food environment in high-income countries. The study found that immigrants strive to access fresh, traditional, and healthier food, but face structural and family-level barriers that may impact the healthiness of the food they acquire.
