Objectively measured physical activity profile and cognition in Finnish elderly twins
Abstract
Introduction: We studied whether objectively measured physical activity (PA) and sedentary
behavior (SB) are associated with cognition in Finnish elderly twins.
Methods: This cross-sectional study comprised twins born in Finland from 1940 to 1944 in the Older
Finnish Twin Cohort (mean age, 72.9 years; 726 persons). From 2014 to 2016, cognition was assessed
with a validated telephonic interview, whereas PA was measured with a waist-worn accelerometer.
Results: In between-family models, SB and light physical activity had significant linear associations
with cognition after adjusting for age, sex, wearing time, education level, body mass index, and living
condition (SB: b-estimate, 20.21 [95% confidence intervals, 20.42 to 20.003]; light physical activity:
b-estimate, 0.30 [95% confidence intervals, 0.02–0.58]). In within-family models, there were no
significant linear associations between objectively measured PA and cognition.
Discussion: Objectively measured light physical activity and SB are associated with cognition in
Finnish twins in their seventies, but the associations were attributable to genetic and environmental
selection.
