Bidirectional Within- and Between-Person Relations Between Physical Activity and Cognitive Function.

ABSTRACT:

Objectives

To examine bidirectional within- and between-person relations between physical activity and cognitive function across 15 years.

Methods

Participants (N = 1,722, age range 40-85 years, 55% women) were drawn from the Betula prospective cohort study. We included 4 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 betw
