## Abstract

Project summary
The Reducing African Americans' Alzheimer's Disease Risk Through Exercise (RAATE) study is funded to
determine the effects of physical activity on risk factors for Alzheimer's Disease in older African American
adults. The study will recruit 200 older African American adults. The study is important because African
American adults are broadly underrepresented in Alzheimer's Disease and Related Disorders (ADRD)
research, leading to limited knowledge of disparities in ADRD causes, preventive strategies, and clinical course
of ADRD. One specific area of ADRD research with especially critical under-representation is lifestyle
modification as a preventive strategy. The COVID-19 pandemic has the potential to significantly hamper efforts
to recruit African American into clinical trials, such as the RAATE study. African Americans are at increased
risk of infection, hospitalization, and death from COVID compared to members of other ethnic groups, and this
may reduce willingness to participate in clinical trials given the need for in-person assessments and
intervention sessions. Our study, Reducing African Americans' Alzheimer's Disease Risk Through
Exercise (RAATE) COVID 19 administrative supplement is designed to determine the impact of COVID-19
on older African Americans' willingness to participate in research. We will form an integrated multidisciplinary
team of scientists in aging research, health disparities, and epidemiology to address this issue in an area
representative of the Deep South, Baton Rouge, Louisiana. This region of the country has been particularly
impacted by COVID-19. In collaboration with investigators from University of North Carolina and using the
Health Belief Model as a theoretical framework, we will develop a questionnaire to assess the impact of
COVID-19 on participant's lifestyle, perceived susceptibility and severity to COVID, benefits and barriers to
research participation, access to healthcare, and trust in information sources. Aim 1 will assess Covid-19-
related changes to the health and well-being of older African Americans. Aim 2 will assess Covid-19-related
knowledge and willingness to participate in research among older African Americans. The final output of the
RAATE-COVID supplement study will be to enhance enrollment in the RAATE study and to develop a set of
generalizable strategies for recruiting sedentary older African Americans into clinical studies of lifestyle factors
in aging.
