The article provides an overview of the contemporary literature on the social and psychological factors which are associated with migration. Derived from the operationalisation of "migration" and an examination of the methodological peculiarities of migration research, a (transactional) stress model of migration is proposed incorporating potentially stress-eliciting influences of migration including occupational pressures, social isolation and/or family-related problems and their impact on psychological and physical health. There are inconsistencies in the findings regarding psychological health, which can in part be explained through the phenomena of the "healthy migrant effect", duration of stay in the host culture or the culture-specificity. Moreover, a discussion is provided of the extent that disorders associated with differentially stressed migrants will be manifested in the health care system. Finally, concluding remarks are offered together with a short discussion of the implication of these findings for future research and social and health policy decision-making.

First generation immigrants show remarkable differences in HCU compared to the native-born Germans and the second generation immigrants. Their HCU seems to be focused on primary care, and access to secondary care might be complicated. It seems relevant to especially pay attention to HCU of first generation immigrants and to support equal access to care for this subgroup.

Further analytical studies are needed to clarify health differences between these groups. Migrants are a heterogeneous group and only group-specific investigations will clarify associations between countries of origin, health status and use of health care institutions.

The sample includes a large variety of immigrants living in Germany and does not refer to a single group. Asylum seekers and undocumented migrants are not included, those immigrants with low language skills might be underrepresented because of the methodology. Against our expectations, no differences in the mental health between imigrants and native Germans could be proven. This finding stands in a marked contrast to the well established deficit-oriented point of view on the health of immigrants.

This is a longitudinal study exploring self‐reported health status and physical symptoms of Russian‐speaking migrants (n = 307) from the states formed after the break up of the Soviet Union. These health status reports were compared with Russians in Russia (n = 300) and non‐immigrant native German test subjects (n = 310). Focus was on the change in subjective evaluation of physical health and adaptation to a new medical health care system as part of the acculturation process following migration. Migrants have more health problems than both the Russians and the native population. In addition to the stress triggered by the critical life event of migration, this finding may also reflect the poorer health status and health care in the countries of origin. In particular, immigrants suffer from headaches and symptoms of exhaustion, which are interpreted as physical correlates of the cognitive overload caused by migration. The subjective state of health of the migrants within the first 18–24 months after arrival (N = 138) showed hardly any changes. However, a high degree of satisfaction with life in the adopted country and an acculturation style distinguished by contact with the host culture correlate to a low level of health problems. The social implications of these findings are discussed. Copyright © 2005 John Wiley & Sons, Ltd.
