Research challenges in the assessment of immigrants' nutrition and health: A narrative review

Abstract

Introduction: This narrative review examines the research methods and analytical approaches used to understand the dietary habits and health access of vulnerable migrants. They often face unique challenges that affect their eating habits
and overall well-being. This review raises methodological issues that researchers must grapple with, including cultural
sensitivity, language barriers, the collection of accurate nutrition data, and guidance to researchers on selecting appropriate tools and strategies to ensure the robustness of their research.
Objectives: This review contributes to enhancing the methodological rigor of future studies and informs evidence-based
interventions aimed at addressing healthcare and nutrition disparities within vulnerable immigrant populations, and
highlights the potential for interdisciplinary collaboration to enhance the effectiveness of interventions targeted at promoting
healthier eating habits among vulnerable immigrants from different countries.
Methods: A systematic search of academic databases was conducted to identify relevant literature focusing on the
research methods and nutrition and health in immigrants. Both qualitative and quantitative studies published within the last decade were included. The selected studies were critically reviewed to analyze the methodologies employed, the
challenges faced, and the key findings obtained.
Conclusion: This review highlights the need for context-specific methodological adaptations, and emphasizes the
importance of cultural sensitivity and collaboration among researchers, practitioners, and policymakers to develop targeted interventions that promote healthier dietary practices and improve the well-being of immigrants in vulnerable circumstances.
