Perceptions of Brain donation and Medical Research Among African American Individuals: Implications for Recruitment and Retention into Alzheimer’s Research
Abstract Background African Americans (AAs) are twice as likely to have Alzheimer’s disease (AD) as their White counterparts; yet, this population is largely missing from brain donation research. According to the National Alzheimer’s Coordinating Center, merely 2% of brain donations are obtained from AAs. Medical mistrust among AAs has been well‐documented as a barrier to medical research participation. The purpose of this study was to expand our understanding of AA perceptions of medical research and brain donation. Method Using validated survey items, a 35‐item cross‐sectional survey was developed to understand attitudes and beliefs about medical research and brain donation among AAs. Surveys were administered via REDCap (Research Electronic Data Capture) and paper in Florida, New York, North Carolina and Ohio, United States from November 2021 to September 2022. Descriptive analysis of data on research participation and trust in medical research was conducted using SAS® software version 9.4. Result A total of 227 AAs participated in this study with about three‐quarters of participants being female. Approximately 90% of AAs reported being born in the US, and nearly half of the sample reported receiving some college education or higher. Only 10.6% of participants reported being very likely to donate their brain to research after death. Despite the low percentage of AAs willing to donate their brain to research, 77.1% had a positive view of medical research and 72.7% trusted researchers in general. In fact, participants perceived that it is “very important” to participate in medical research to help future generations (78.4%), to learn more about AD (66.5%), and receive medical information (56.8%). Conclusion Most AAs in this study reported strong trust in medical research and researchers. Medical mistrust may not be a significant barrier to participation in brain donation or AD research for AAs in this sample. Improved health literacy in AD research and brain donation procedures may facilitate engagement of AAs to participate in such research. Findings from this study will be used to inform the development of a culturally relevant health literacy program, with a focus on brain donation and AD research, to enhance opportunities for recruitment and retention of AAs
