Participation of Turkish Migrants in an Epidemiological Study: Does the Recruitment Strategy Affect the Sample Characteristics?

Journal of Immigrant and Minority Health volume 21, pages 811–819 (2019)Cite this article

Abstract

Migrants are often poorly represented in epidemiological studies which limits the generalizability of the results of population-based studies. This study aimed to assess whether a community-based sampling (CBS) of persons of Turkish origin leads to differences in the participants’ characteristics compared to a register-based sampling (RBS). The two sampling strategies were used to recruit participants in three cities in Germany (CBS: n = 641; RBS: n = 578). We compared sociodemographic, migration- and health-related characteristics. Census data were used as an external reference. Lower German language skills and a lower acculturation status were more prevalent in the CBS than in the RBS. While age and sex adjusted obesity prevalence differed [CBS: 37.8 (33.6–42.4); RBS 30.0 (26.3–34.0); census data 19.1 (18.2–20.1)], most other health indicators were similar across the samples. In conclusion, the CBS approach led to a greater representation of persons of Turkish origin with lower language skills and lower acculturation status. Nevertheless, both recruitment strategies provided similar estimates of health status indicators.
