Determinants of Self-rated Cognitive Health among Older Korean Americans.

Abstract

In response to the dearth of information on cognitive health in older ethnic minorities, in the present study, we examined factors associated with self-rated cognitive health (SRCH) in older Korean Americans. Drawing from the World Health Organization's framework of social determinants of health, we examined how a broad spectrum of factors might influence the way in which older Korean Americans perceive and evaluate their own cognitive health. Using data from the Study of Older Korean Americans (SOKA; N = 2,061, mean age = 73.2), a series of hierarchical linear regression models of SRCH was tested with sequential entry of predictors: (1) Mini-Mental State Examination (MMSE) score of cognitive status, (2) demographic variables, (3) physical and mental health status, (4) health behaviors, and (5) socio-cultural and community factors. In addition to cognitive screening outcomes, each set of variables made a significant contribution to the predictive model of SRCH. Positive ratings of cognitive health were observed among older individuals with greater education, good physical and mental health, involvement in regular exercise, and socio-cultural resources (social networks, acculturation, and family solidarity). The SRCH of older adults goes beyond cognitive screening outcomes, suggesting a need to incorporate the various sources of social determinants when seeking to promote the cognitive health of older populations.
