Leisure-Time Physical Activity, Subjective Age, and Self-Rated Memory in Middle-Aged and Older Adults.

Memory concerns are common in middle-aged and older adults. This study investigated the relation of leisure-time physical activity to self-rated memory and the possible mediating role of subjective age in this relationship in middle-aged and older adults. Cross-sectional analyses were conducted with a sample of 1,608 middle-aged and older adults from the second wave of the National Survey of Midlife Development in the United States (MIDUS2). In a path analysis conducted with Mplus, a higher level of leisure-time physical activity was associated with a more positive appraisal of memory compared to others of one's age; younger subjective age partially mediated this relationship. Neither gender nor age-group moderated the association. Age, race, education, marital status, health status, and negative affect were controlled for in the analyses. These findings suggest a possible role of physical activity in countering the effects of age stereotypes on perceived memory.
