背景资料：2011年，德国近20.0%的人口有移民背景。关于他们健康状况的研究参与率往往很低。我们研究的目的是比较不同的抽样策略，并测试不同的方法来招募移民进行流行病学研究。方法：德国国家队列的四个招募中心招募来自前苏联国家的土耳其裔和德裔移民。研究采用了以登记为基础(从居民登记办公室随机抽取样本)和以社区为导向的策略。参与者接受了体检，并自填了一份问卷。结果：采用的方法：以社区为导向的策略包括从移民网络中获取关键人员，以支持在移民环境中招募、邀请谈话和分发学习材料等。登记数据中的识别变量是姓名、国籍或出生国。除一个中心外，所有中心都使用双语学习材料和学习人员。参与：比较两种战略时，基于登记的参与率从10.1%到21.0%(n=668人)，面向社区的招募产生了722人。结论：基于登记的招聘应使用姓名、国籍和出生国的组合，以便不仅限于识别具有外国国籍的人。然而，根据研究人员的说法，让具有相同文化背景的关键人物参与的以社区为导向的方法会更好地被参与者接受。此外，它还涵盖了一个更加多样化的群体。然而，它很耗时，需要相当多的工作人员。进一步的研究应该确定这两种策略组合的有效性。
Background: In 2011, almost 20.0% of the population of Germany had a migration background. Studies on their health tend to have low participation rates. The aim of our study was to compare different sampling strategies and to test different approaches to recruit migrants for an epidemiological study. Methods: Four recruitment centres of the German National Cohort recruited persons of Turkish origin and ethnic German immigrants from former Soviet Union countries. A register-based (random samples from residents' registration offices) and a community-orientated strategy were applied. Participants underwent a medical examination and self-completed a questionnaire. Results: Used approaches: The community-orientated strategies comprised the acquisition of key persons from migrant networks to support the recruitment, invitation talks and distribution of study materials in migrant settings, etc. The identifying variables in the registry data were name, nationality or country of birth. All but one centres used bilingual study material and study staff. Participation: When comparing the two strategies, the register-based participation rates ranged from 10.1 to 21.0% (n = 668 participants) and the community-oriented recruitment resulted in 722 participants. Conclusion: 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.
