PROSTATE CANCER
In this randomized clinical trial of online prostate cancer videos, for both Black and White adults, physicians were trusted more than patients as the source of information, and there was less trust in videos about clinical trials vs screening. Black adults had significantly greater trust in information presented by a Black speaker.These results are consistent with other studies highlighting the importance of racial concordance in health information for Black adults. For example, in a randomized clinical trial of physician-delivered videos about COVID-19, messages from race and ethnicity–concordant (vs discordant) physicians significantly increased information-seeking among Black participants.Our results highlight actionable opportunities to improve care. They suggest the importance of increasing diversity in medical information for patients, and the importance of physicians as trusted sources. Particularly considering the substantial amount of circulating misinformation,Our data also underscore the importance of public education about the value of clinical research and protection of human participants. Black adults represent only 0.5% and 6.7% of participants in prostate cancer screening and treatment trials, respectively,Online platforms are an important source of health information, yet content on these platforms is not representative of diverse populations.
