Dementia is a major contributor to mortality in the U.S. As the population ages, dementia incidence is projected to quadruple in the near future. Although a number of studies have examined the geographic disparities in dementia mortality risk in the U.S., our understanding of how contextual factors may contribute to such disparities remains limited. This knowledge gap is partially attributed to the under-representation of racial/ethnic minorities in current dementia studies. In this study, we propose to employ a logistic regression approach to examine the socio-ecological disparities in dementia mortality risk in the U.S. Specifically, we investigated the relationship between different aspects of socio-physical environment and individual dementia mortality risk. We used the 2010 multiple-cause death certificate data requested from the National Center of Health Statistics (NCHS) at the Centers for Disease Control and Prevention (CDC) in our study. Results revealed that area socioeconomic deprivation and social cohesion are both significant factors in predicting one's risk of dementia death, independent from individual socio-demographic factors. The relationships between individual dementia mortality risk and socio-physical environment measures also differ between urban-rural categories. The results will be useful for generating etiological hypotheses of dementia mortality as well as informing policies and initiatives aimed at tackling social and spatial inequalities in dementia mortality and reducing dementia mortality risk at the population level.
