Objectives: To analyze the relationship between physical activity, as assessed by accelerometer, with central and peripheral augmentation index and carotid intima media thickness (IMT) in adults.
Methods: This study analyzed 263 subjects who were included in the EVIDENT study. Physical activity was assessed during 7 days using the ActigraphGT3X accelerometer (counts/min). Carotid ultrasound was used to measure carotid IMT. The Sphygmo Cor System was used to measure central and peripheral augmentation index (CAIx and PAIx).
Results: Mean age 55.85±12 years; 59.30% female; 26.7 body mass index and blood pressure 120/77mmHg. Mean physician activity counts/min was 244.37 and 2.63±10.26min/day of vigorous or very vigorous activity. Physical activity showed an inverse correlation with PAIx (r=-0.179; P<.01) and vigorous activity day time with IMT(r=-0.174; P<.01), CAIx (r=-0.217; P<.01) and PAIx (r=-0.324; P<.01). After adjusting for confounding factors in the multiple regression analysis, the inverse association of CAIx with counts/min and the time spent in vigorous/very vigorous activity was maintained.
Conclusion: The results suggest that both physical activity and time spent in vigorous or vigorous activity are associated with the central augmentation index in adults.
