BackgroundSubjective cognitive impairment (SCI) predicts Alzheimer's disease and related dementias (ADRD). Identifying SCI correlates may identify cognitive risk earlier in the ADRD continuum. We examined SCI correlates among older non-Hispanic Black (NHB) and non-Hispanic White (NHW) men.MethodCross-sectional data were from 669 men in the 2012 National Health and Aging Trends Study. Logistic regression was used to identify SCI correlates, accounting for complex sampling and attrition.ResultHigher education (OR = 0.33, 95% CI: 0.13-0.87) and former smoking (OR = 0.38, 95% CI: 0.16-0.91) were associated with lower SCI odds. Sleep difficulties (OR = 2.81, 95% CI: 1.22-6.47), multimorbidity (OR = 2.16, 95% CI: 1.09-4.29), and ADL disability (OR = 4.19, 95% CI: 2.03-8.61) were associated with higher odds.DiscussionEducation, smoking status, sleep, multimorbidity, and functional status may be important SCI correlates among older NHB and NHW men. Addressing modifiable correlates may support cognitive health earlier in the ADRD continuum.
