Successful Retention Strategies for Research Targeting Hispanic/Latinx (Including Recent Immigrants) in the Midwest Region of the United States.

Recruiting and retaining Hispanic/Latinx (H/L) participants, specifically undocumented immigrants, is challenging in part because of the mistrust and fear in participating in research studies. Additionally, only a few longitudinal studies describe the recruit and retention strategies among Mexican and Central American immigrants aiming to expand the knowledge base about those underprivileged groups; this was the objective of the 6-year longitudinal VidaSana study. In the present methods report, we specifically omit the presentation of results from the empirical data findings of the VidaSana study: the present report describes the process and offers a subjective appraisal of multiple and complementary approaches in the recruitment and retention strategies for Hispanics living in the Midwest region of the United States, including very recently arrived immigrants. This study was able to effectively recruit and retain (81.7%) a cohort of Mexican and Central American immigrants within a period of 36 months. Our recruitment and retention performance were successful in the context of the hostile environment against immigration that dominated the national landscape at the time of our study. The present methods report of the VidaSana study provides an insightful understanding in recruiting and, in particular, retaining H/Ls and H/L recent immigrants into longitudinal studies.
