IntroductionThis study estimates the prevalence of food insecurity, mental well-being, and their associations among immigrants and compares the food insecurity-mental well-being associations with nonimmigrants globally and by region.MethodsThe Gallup World Poll data from 2014 to 2019 were analyzed in 2021. A total of 36,313 immigrants and 705,913 nonimmigrants were included. Food insecurity was measured by the Food Insecurity Experience Scale. Mental well-being was assessed using the Negative Experience Index and Positive Experience Index. A community attachment index was used to measure the living environment. Multilevel mixed-effect linear models were used to examine how the Negative Experience Index/Positive Experience Index was associated with food insecurity and the community attachment index in immigrants and nonimmigrants, adjusting for sociodemographic characteristics, survey years, and country fixed effects. The modifying effects of immigration status on food insecurity-mental well-being associations were tested.ResultsThe weighted proportion of food insecurity among global immigrants was 38.6% during 2014-2019. In the pooled adjusted model, food insecurity was dose-responsively associated with greater Negative Experience Index and lower Positive Experience Index than the food-secure ref (p<0.001 for trend). Similar dose-response associations were observed in nonimmigrants and in region-specific analyses. Community attachment marginally affected the food insecurity-mental well-being associations (all p≤0.001 for interaction). Immigration status significantly modified the food insecurity-mental well-being associations in all analyses (all p=0.01 for interaction), and immigrants experienced poorer mental well-being than nonimmigrants at the same level of community attachment and food insecurity.ConclusionsFood insecurity is prevalent and is associated with poor mental well-being in immigrants worldwide. Future interventions are needed to alleviate food insecurity and promote community attachment to improve mental health among immigrants, especially in Asian and Pacific countries.Copyright © 2022 American Journal of Preventive Medicine.
