Determinants of Food Security Among People from Refugee Backgrounds Resettled in High-income Countries: A Systematic Review and Thematic Synthesis

Food is intrinsically linked to culture, identity, and for people with lived refugee experiences, cultural foods are a critical part of settlement into a new country, which is often a time of high stress and dislocation from friends and family. However, cultural foods in settlement countries may be unavailable or inaccessible, adversely impacting on food security. This systematic review aimed to identify facilitators and barriers to accessing foods in high-income countries for people with lived refugee experiences. Sixteen health databases were searched from June 2020 and April 2021 and 22 articles met the inclusion criteria. Bias was assessed using a modified thematic synthesis method and the relevant Joanna Briggs Institute risk assessment checklist. Findings were thematically synthesised and the socio-ecological model and postcolonialism were used as a lens through which the data was viewed. Analysis revealed three themes: "Practicalities and Pragmatism"; "Identity, Belonging and Placemaking"; and "Postcolonial and Societal Influences". The determinants of food security were present across all levels of the socio-ecological model and people with lived refugee experiences used practical and pragmatic strategies to feed their families. Food was intrinsically linked to identity, belonging and placemaking, and as such, people preferred consuming cultural foods. Societies adversely affected the food security of people from refugee backgrounds by limiting their access to resources and restricting cultural food gathering practices, impacting on their ability to access or afford foods, especially cultural foods. To improve food security for people with lived refugee backgrounds, governments and organisations should collaborate with the cultural communities with lived experiences of accessing cultural foods, appreciate their strengths, and recognise the value of social and cultural capital.
