Abstract
INTRODUCTION: Neighborhood disadvantage may be an important determinant of cardiometabolic health and cognitive aging. However, less is known about relationships among individuals with mild cognitive impairment (MCI). METHODS: The objective of this study is to investigate the relationship between neighborhood disadvantage measured by national Area Deprivation Index (ADI) rank with measures of cardiometabolic health and cognition among Wake Forest (WF) Alzheimer's Disease Research Center (ADRC) participants, with and without MCI. RESULTS: ADI was positively associated with blood pressure and cardiometabolic index (CMI), and negatively associated with global and Preclinical Alzheimer's Cognitive Composite (PACC5) scores, in cognitively unimpaired (CU) individuals. ADI was only positively associated with hemoglobin A1c (HbA1c) in MCI. DISCUSSION: Neighborhood disadvantage is associated more strongly with measures of cardiometabolic health and cognition among CU individuals rather than MCI. These findings demonstrate a need for structural solutions to address social determinants of health in an attempt to reduce cardiometabolic and cognitive risks.
