Race, ethnicity, and ancestry reporting in genetic counseling research: A focused mapping review and synthesis

Abstract

Studies on the use of Race, Ethnicity, and Ancestry (REA) concepts and terms in genetic research are limited. We aimed to describe the collection, reporting, and use of REA data in genetic counseling research. We undertook a focused mapping review and synthesis of the Journal of Genetic Counseling 2021 publications. We used a mapping proforma based on the Race, Ethnicity, And Culture in Health checklist to extract data. Of the 177 screened articles, 132 met our inclusion criteria of reporting primary data about participants. The sample REA characteristics were described in 80 (61%) articles, with 6% providing a definition or conceptualization of the REA term/s used and 23% including a rationale for their study in terms of REA factors. Group labels were most often reported using population descriptors, such as "race," "ethnicity," "race/ethnicity," and "ancestry." Several group labels were used under different population descriptors. For instance, the group labels "White" and "Asian" were used under all population descriptors. Most studies (79%) ascertained REA characteristics by participants' self-report. Three (15%) of the 20 qualitative studies mentioned the relevance of the interviewers' REA characteristics in relation to the participants' REA characteristics. Of the 55 quantitative studies, 19 (35%) used REA factors in the data analysis. Of the 80 articles describing the sample REA characteristics, 20% referred moderately or a great deal to any REA factors in the results interpretation, 46% acknowledged the REA factors in the study limitations, and 15% discussed the implications of REA reporting for genetic counseling practice. Our review documents extensive variation in how sample REA characteristics are described and used in genetic counseling research. Our findings provide a baseline against which to evaluate the effects of guidelines and recommendations for the collection, responsible use, and report of participants' REA characteristics in genetic counseling research.

Keywords: ancestry; disparities; diversity; ethnicity; genetic counseling; race.
