Contemporary Prevalence and Prevention of Micronutrient Deficiencies in Refugee Settings Worldwide

This paper reviews the state of knowledge on micronutrient deficiencies among refugee populations, who face heightened risk due to their circumstances of displacement, living conditions, and reliance on food aid. The author finds that despite well-documented outbreaks of these deficiencies, few prevention programs — such as fortifying food supplies or diversifying diets — have been rigorously evaluated for effectiveness in refugee settings specifically.

• Refugee populations face elevated risk of micronutrient deficiencies due to displacement, dependence on food aid, and challenging living conditions.
• Common prevention strategies, including food fortification and dietary diversification, have rarely been systematically tested for impact in refugee contexts.
• Approaches that work well in other populations may not translate effectively to refugee situations, meaning solutions can’t simply be borrowed from elsewhere.
• The paper calls for more rigorous, systematic testing of nutrition interventions in refugee settings to build a stronger evidence base and improve prevention efforts going forward.
