Associations of Subjective Cognition With Community Participation and Health Conditions in Middle-Aged and Older Adults.

Understanding factors associated with subjective cognition in middle-aged and older adults is important. The objective of this study was to investigate the extent to which community participation, health conditions, and demographics increase the risk of subjective cognitive decline (SCD) in adults aged 45 and older, as well as how these factors are associated with self-perceived executive ability in those with SCD. A cross-sectional study was conducted with 93 community-dwelling participants, categorized into those with SCD (N = 42) and those without SCD (N = 51). Logistic and multivariable linear regression models were built. The results showed that depressive symptoms and concerns about executive ability significantly increased the risk of SCD in the logistic model. The linear model indicated that lower levels of community participation and education were associated with greater concerns about executive ability among those with SCD. Conclusion: Addressing depressive symptoms and executive ability in SCD is crucial; occupational therapy should facilitate community participation to support those with SCD.
