[Life course epidemiology in migrant health research]

From free choice to forced flight, there are many reasons for migration. Accordingly, the backgrounds and living conditions of migrating people are also diverse. The different associated exposures affect the health of migrants and their children. To capture such a complex phenomenon, an approach is required that takes specific living conditions during the life course of migrants into account.An established methodological approach that can accomplish this is life course epidemiology. When applied to migrating populations, it examines exposures before, during, and after migration. In epidemiological research on the health of migrant populations, it is desirable to consider all three phases. This is countered by the fact that reliable data on the entire life course is not always available.A valid, timely collection and data protection-compliant linkage of longitudinal data from different sources can improve life course-related research on the health of migrants in Germany. In the future, corresponding data should also be included from the countries of origin of migrants.
