Health, Memory Complaints and Cognitive Performance in Older Adults: Relationship Analysis.

Objective: The aim of the present study was the examination of the relationships among multimorbidity and subjective and objective cognitive performance, as well as the role of some demographic, social and health variables. We also investigated the protective role of social participation and physical activity against the impact of multimorbidity on cognition. Subjective cognitive performance was measured by memory complaints, while the objective one (a part of it) was assessed by verbal fluency.
