Associations of objectively measured physical activity and sedentary time with all-cause mortality in Japanese older adults: a 10-year prospective study.

ABSTRACT:

Objective

To examine the associations of accelerometer-measured physical activity and sedentary time with all-cause mortality in older Japanese adults.

Methods

A total of 1723 independent Japanese adults aged ≥65 years were followed from 2011 to 2021. Moderate-to-vigorous physical activity (MVPA), light physical activity (LPA) and sedentary time were measured using a triaxial accelerometer secured to participants' waists.

Results

Over a median follow-up of 9.9 years, 336 deaths were recorded. When examined as tertiles, higher MVPA (both ≥10 and <10 min bouts) and LPA were associated with a lower mortality risk. Additional adjustment for MVPA attenuated the associations of LPA, but the HRs in the highest tertile remained significant. Longer sedentary time was significa
