The paucity of public health messages that directly address communities of color might contribute to racial and ethnic disparities in knowledge and behavior related to coronavirus disease 2019 (COVID-19). Physicians have increasingly reached out to the community on social media. Whether or not these messages matter, and whether or not physician race/ethnicity affects information uptake is not clear.
Researchers from MIT Department of Economics, Massachusetts General Hospital, and other top academic institutions, randomly assigned 14,267 self-identified Black or Latinx adults to either first view three video messages regarding COVID-19, delivered by physicians, that varied by physician race/ethnicity, acknowledgment of racism/inequality, and community perceptions of mask-wearing and then answer questions, or answer questions first and then watch the videos. The goal was to determine whether physician-delivered prevention messages affect knowledge and information-seeking behavior of Black and Latinx individuals and whether this differs according to the race/ethnicity of the physician and tailored content. The researchers found a small but statistically significant increase in COVID-19 knowledge when viewing the video first that did not differ by race concordance between the physician messenger and the viewer. However, information seeking (click through on links that offered further information on COVID-19) was higher among African American participants after they viewed messages from African American physicians.
