Comparing sampling strategies to recruit migrants for an epidemiological study. Results from a German feasibility study

Abstract

Register-based recruitment should use a combination of name, nationality and country of birth in order not to be limited to identifying persons with a foreign nationality. However, according to the study staff, the community-oriented approach involving key persons of the same cultural background leads to a better acceptance by the participants. Also, it covers a more heterogeneous group. Yet, it is time-consuming and needs considerably more staff. Further research should establish the effectiveness of a combination of both strategies.
