Abstract [en]
Objectives: To examine bidirectional within- and between-person relations between physical activity and cognitive function across 15 years.
Methods: Participants (N = 1722, age range 40-85 years, 55% women) were drawn from the Betula prospective cohort study. We included four waves of data. Bivariate latent curve models with structured residuals were estimated to examine bidirectional within- and between-person relations between physical activity and cognitive function (episodic memory recall, verbal fluency, visuospatial ability).
Results: We observed no statistically significant bidirectional within-person relations over time. Higher levels of physical activity at baseline were related to less decline in episodic memory recall. Positive occasion-specific within- and between-person relations were observed, with the most consistent being between physical activity and episodic memory recall.
Discussion: The lack of bidirectional within-person relations indicate that shorter time lags may be needed to capture time-ordered within-person relations. The link between higher physical activity at baseline and less decline in episodic memory recall over time may indicate a protective effect of physical activity on episodic memory recall.
