Correlates of Subjective Cognitive Decline in Black American Men.

Past research suggests that subjective cognitive decline serves as an early and potentially important indicator that individuals may be at risk for future cognitive decline or neurodegenerative conditions. However, there is a dearth of studies on factors influencing the experience of subjective cognitive decline in Black Americans, especially in Black American men.The current study explored correlates of subjective cognitive decline in Black American men.A total of 117 Black American men, with a mean age of 38.5 (SD = 7.14) years, participated in the study.Participants completed a survey that assessed their demographic characteristics, self-rated health, neighborhood problems, length of residency in neighborhood, bodily symptoms, sleep comorbidities, sleep difficulties, and subjective cognitive decline. Linear regression analyses was performed and standardized beta coefficients were reported to describe the estimated independent effect of the predictor variables.We found that socioecomic status (β = -.222, p=.003), bodily symptoms (β = .246, p=.005), length of residency in neighborhood (β = .157, p=.029), and sleep difficulties (β = .305, p<.001) were significant correlates of subjective cognitive decline among Black American men.These findings underscore the intricate roles of socioeconomic status, bodily symptoms, neighborhood factors, and sleep health in shaping subjective cognitive experiences in this population. Research on subjective cognitive decline can contribute to the early identification of individuals at risk for cognitive decline, allowing for timely interventions, lifestyle modifications, and potential preventive measures.
