β = standardized coefficient; PA = physical activity; MVPA = moderate to vigorous physical activity; WMH = white matter hyperintensities. Wear time denotes total time the accelerometer was worn. Model 1: All light PA and MVPA as independent variables. Model 2: Additionally adjusted for age and accelerometer wear time. Statistically significant (p < 0.05) results appear in bold font.
