Aldridge RW, et al. - Via performing this systematic review and meta-analysis, researchers reviewed and synthesized available mortality data on international migrants. Studies that reported on mortality outcomes for international migrants of any age residing outside their country of birth were included in the analysis. Studies that enrolled individuals solely from intensive care or high-dependency hospital units, with an existing health condition or status, or a particular health exposure were excluded. Studies limited to maternal or perinatal outcomes were also deemed ineligible. Outcomes revealed that, compared with general populations, international migrants have a mortality advantage, which persists across the majority of International Classification of Diseases, tenth revision (ICD-10) disease categories. The identified mortality advantage will be illustrative of international migrants in high-income countries who are studying, working, or have joined family members in these countries. As little data were available for marginalized groups in low- and middle-income countries, these results might not indicate the health outcomes of these groups, highlighting an important gap in existing research.
