To the Editor In a recently published article about risks of mental disorders associated with various types of foreign migration, Cantor-Graae and Pedersen1 reported higher risks for schizophrenia-related disorders in all types of migrants, except in children born to expatriates. In addition, which I found particularly interesting, they found lower risks for affective, personality, and substance use disorders in first- and second-generation migrants with 2 foreign-born parents but higher risks in foreign-born adoptees, second-generation immigrants with 1 foreign-born parent, and native Danes who resided abroad. The question is, what is the difference between these 2 types of migrants compared with the other types?
