Step volume and intensity in older adults:Commentary on 'Association of accelerometer-derived step volume and intensity with hospitalizations and mortality in older adults:A prospective cohort study'
In 2021,Manas et al.1 used data from the Toledo Study for Healthy Aging and reported that high accelerometer-derived step volume and(what they labeled)intensity were significantly associated with lower hospitalization(average followup=3.1 years)and all-cause mortality(average followup=5.7 years)in 768 older adults(average age=78.8±4.9 years,mean±SD).Step volume(expressed as steps/day)was averaged across all compliant days(i.e.,those with8 h/day of valid wear time).For their purposes,the authors defined intensity as the total step volume divided by the total valid minutes of accelerometer wear time.
