Equity impacts of interventions to increase physical activity among older adults: a quantitative health impact assessment

Table 1 Physical activity change in people aged ≥55 years across scenarios

Name of scenario	Description of intervention-induced change in MVPA-minutes (and corresponding MET-hours^a) per week
#Reference-scenario	Physical activity remains at the currently observed level
#1: PROMOTE-undifferentiated	+ 7.59 MVPA-minutes (+ 0.76 MET-hours) per week, for older adults with low, medium or high education
#2: PROMOTE-differentiated	+ 19.70 MVPA-minutes (+ 1.97 MET-hours) per week for older adults with low education, + 5.80 MVPA-minutes (+ 0.58 MET-hours) per week for older adults with medium education, + 9.53 MVPA-minutes (+ 0.95 MET-hours) per week for older adults with high education
#3: Downward-gradient	+ 19.70 MVPA-minutes (+ 1.97 MET-hours) per week for older adults with low education, + 9.53 MVPA-minutes (+ 0.95 MET-hours) per week for older adults with medium education, + 5.80 MVPA-minutes (+ 0.58 MET-hours) per week for older adults with high education
#4: Upward-gradient	+ 5.80 MVPA-minutes (+ 0.58 MET-hours) per week for older adults with low education, + 9.53 MVPA-minutes (+ 0.95 MET-hours) per week for older adults with medium education, + 19.70 MVPA-minutes (+ 1.97 MET-hours) per week for older adults with high education
#5: Equalizing	All older adults with low or medium education adapt the physical activity profile of older adults with high education
#6: Guideline	All older adults increase their physical activity level to ≥300 MVPA-minutes (≥22.50 MET-hours) per week

^a assuming 6 metabolic equivalents of tasks (METs) for activities in moderate-to-vigorous physical activity (MVPA) intensity, being the intersection of moderate-intensity activities with an energy expenditure of 3–5.9 METs, and vigorous-intensity with ≥6 METs [43, 44]. Exemplary calculation: 7.59 MVPA-minutes*6METs/60 min = 0.759 MET-hours
