in the physical activity guidelines, only moderate and vigorous physical activity was included in calculating the physical activity levels. 10 Data were converted to metabolic equivalents minutes per week following established criteria: minutes per week of activity was multiplied by an intensity

found in self-reported physical activity data. Interestingly, Hispanic/Latina women self-reported higher levels of moderate and vigorous physical activity than African American; however, accelerometry demonstrated African American women actually had significantly higher levels of MVPA. When comparing

In addition, the amount of walking and stair climbing were specifically assessed in 2

used for analysis for the data: walking equivalent to 3.3 METs, moderate physical activity equivalent to 4.0 METs, and vigorous physical activity equivalent to 8.0 METs ( International Physical Activity Questionnaire, n.d. ).

In Figure  3 , the time spent above incremental 50 m g thresholds is shown, with MVPA and vigorous physical activity determined from both Hildebrand et al ( 15 ) and Phillips et al ( 22 ) children’s cut points. Figure 3 —The time spent

sedentary; 66.5% were aged ≥ 70 years; 64.5% were women; and 52.1% were classified with BMI ≥ 28 kg/m 2 . The mean age was 73.9 years (95%CI: 73.2 to 74.6). The average time spent in moderate and vigorous physical activity was 9.73 min per day (95%CI: 8.27 to 11.19). The average sedentary time per day was

pertinent to B-Well. 29 We downloaded minute-by-minute step frequency data weekly and counted MVPA minutes by setting an intensity threshold for a minute to qualify as activity. A cutoff of 100 steps per minute was used for moderate physical activity, 30 , 31 and vigorous physical activity was defined as

The moderate and vigorous physical activity classifiers were aggregated for time in MVPA. Wear time validation was employed using the Choi et al 22 algorithm. The ActiLife 6
