Abstract

BackgroundThere are concerns about the representation of vulnerable and underrepresented racial-ethnic minorities in biomedical and public health research, particularly when the research requires the collection of biospecimens. The current paper reports on the acceptability, feasibility, and ethics of saliva collection in a study examining the relationship between chronic stressors among mostly mixed-status, Latinx families (N = 30) during high immigration enforcement.MethodsData for this study included anthropometric measures and salivary biospecimens from each family member (N = 110) and a household survey. Data for this analysis are from ethnographic field notes, which were analyzed using a bricolage of critical ethnography and case study analysis techniques.ResultsWe discuss the feasibility, aversions, acceptability, and ethical implications of integrating salivary biomarkers with Mexican-origin mixed-status families living in an area with restrictive immigration enforcement policies. We present the recruitment and data collection strategies used by the research team to gain participants’ trust, retain families, and maintain confidentiality.ConclusionWe recommend that researchers who obtain biospecimens from Latinx, Mexican-origin, and/or immigrant populations answer the participants’ questions honestly and without fear that they will not understand the science to obtain voluntary assent and consent. We recommend that researchers be knowledgeable of the sociopolitical context that the Latinx, immigrant, and in particular, mixed-status families inhabit so that they are prepared to provide informational resources. Finally, we think it is imperative that the study team in the field be bilingual, multicultural Latinx persons who identify with the community.
