Racial/Ethnic Disparities in ADRD Risk: The Impact of Social Relations

Project Summary

Growing evidence suggests that certain racial/ethnic minority groups experience the highest incidence of Alzheimer's disease and related dementias (ADRD) risk in the US (Mayeda et al., 2016). Longitudinal studies with diverse samples that collect social and behavioral measures in early and midlife hold exceptional promise for identifying modifiable protective factors for cognitive health and life course pathways of ADRD risk. Social relations, a multidimensional concept with high intervention potential, have been found to predict cognitive health and ADRD, though these associations may differ across race/ethnicity. Still not identified are: (1) how early and mid-life social relations are associated with ADRD risk in different racial/ethnic groups; and (2) specific aspects of social relations that modify ADRD risk. Characterizing how social relations vary as a function of race/ethnicity and clarifying unique links to ADRD risk will advance the field in terms of theory and intervention. This study will leverage four waves of the Social Relations Study to examine social relations and ADRD risk across racial/ethnic groups.
