    In 2019, 272 million people worldwide were international migrants
    .


    Europe (82 million) and North America (59 million) are the world leaders in accepting immigrant populations, and these numbers are expected to rise in the coming decades


    This is because there is a healthy immigration effect, that is, those who are healthy are more likely to emigrate


    In addition, the country of origin of immigrants is closely related to ethnic, cultural and biological factors, which can affect the incidence of stroke risk factors such as hypertension and metabolic syndrome, as well as immigration level (refugee vs.
    skilled migrant) and cultural adaptation.
    so .
    In addition, ethnic differences in the incidence of stroke subtypes such as ischemic stroke and intracerebral hemorrhage have also been reported before and need to be considered .

    In this way, Manav V.


    Vyas and others of the University of Toronto in Canada conducted a population-based retrospective cohort study to assess the relationship between immigration status and stroke (ischemic stroke, intracerebral hemorrhage or subarachnoid hemorrhage) or transient The relationship between the incidence of ischemic attack (TIA) and the type of stroke



    They conducted a retrospective cohort study of 8 million adults (15% immigrants) who lived in Ontario, Canada on January 1, 2003.


    They had no previous history of stroke or transient ischemic attack (TIA)


    During the follow-up of 109 million person-years, they observed 235,336 strokes or TIA events
    .

    Compared with long-term residents, the incidence of stroke or TIA is lower among immigrants (10.

    23.

    Immigrants from the Caribbean (HR 0.

    85), compared with immigrants from other parts of the world, are related to immigration status The reduction in stroke risk is not so obvious
    .

    The important significance of this study is that it has found that the incidence of stroke or TIA among immigrants is lower than that of long-term residents, and varies with age, stroke type, and country of origin
    .


    This knowledge may be useful for developing targeted primary stroke prevention strategies


    The incidence of stroke or TIA among immigrants is lower than that of long-term residents, and varies with age, stroke type, and country of origin
