Discusses the mental health of Muslim immigrants (primarily North Africans, Pakistanis, and Turks) in western European countries, particularly Belgium, France, Germany, and the UK. The historical pattern of Muslim migration and sociocultural background of immigrants have implications for concerns related to acculturation, identity, and socialization of children of immigrants. Data on the prevalence of psychiatric disorders and somatization are reported for Pakistani, Turkish, and North African immigrants to western Europe. These data suggest that the mental health of Muslims in Europe is better or at least the same as that of the indigenous population, possibly due to the emphasis on close relations and mutual respect in the family and the religious and social support provided within the Muslim community.
