However, due to measurement limitations that often oversimplify the multidimensional construct of SES, fundamental questions regarding the relationship between socioeconomic disadvantage and cognition remain. We examined multiple SES characteristics at the individual and area‐level simultaneously in association with diverse cognitive processes in a large, community‐based older adult sample. Method We conducted a cross‐sectional analysis of 648 cognitively unimpaired older adults (Mean age = 69.88 + 3.75 years) enrolled in a multi‐site, randomized clinical trial: Investigating Gains in Neurocognition in an Intervention Trial of Exercise (IGNITE). Participants completed a comprehensive cognitive assessment that included tests of episodic memory, executive function, processing speed, working memory, and visuospatial abilities. Multiple dimensions of SES were obtained including area‐level (Area Deprivation Index), subjective (US Ladder from MacArthur Socioeconomic Status Index), and objective SES. We generated a novel data‐driven measure of objective SES from measures of income, savings, debt‐adjusted savings, and financial stability, and examined associations of SES indicators with cognition in multiple linear regression models that controlled for age, sex, race/ethnicity, and study site. Result Lower objective SES was associated with poorer performance on all cognitive domains: episodic memory (β = 0.115, p = 0.003), executive function (β = 0.210, p < 0.001), processing speed (β = 0.224, p < 0.001), working memory (β = 0.199, p < 0.001), and visuospatial abilities (β = 0.164, p < 0.001). Subjective SES was associated with poorer performance on all cognitive domains except episodic memory. Area‐level SES was not associated with any cognitive domain (ps > 0.05). When examining all SES indicators simultaneously, only the objective SES composite remained significantly associated with cognitive function. In secondary models, the objective SES composite score explained additional variance beyond education, income, and their standardized average. Conclusion Objective SES showed the broadest and most robust associations with cognitive function relative to subjective and area‐level indicators among cognitively normal older adults. Future studies may benefit from examining multiple financial indicators to better detect the extent and magnitude of cognitive deficits related to socioeconomic disadvantage in older adulthood. | |
