Revisiting the association of sedentary behavior and physical activity with all-cause mortality using a compositional approach: the Women's Health Study.

ABSTRACT:

Background

While physical activity has consistently been associated with decreased mortality rates, it remains unknown if there is a single "ideal" combination of time in physical activities of different intensities and sedentary behavior (SB) associated with the lowest rate. This study examined the associations of combinations of time in moderate-to-vigorous intensity (MVPA), higher-light intensity (HLPA), lower-light intensity activities (LLPA), and SB with mortality rates in older women.

Methods

This prospective cohort study included 16,676 older women from throughout the United States enrolled in the Women's Health Study. Women wore accelerometers on their hip from 2011 to 2015 and were followed through 2017 (mean (SD) of 4.3 (1.1) years). Deaths were confirmed with medi
