Values are relative change scores (means ± standard deviations) within groups. Post = difference between post and baseline data; Post3m = difference between post 3 months and baseline; post6m = difference between posttest 6 months and baseline; post1y = difference between posttest 1 year and baseline; MIG Minimal Intervention Group, PG Pedometer Group, DG Display Group, CoachG Coaching Group, PAL physical activity level, MVPA minutes of moderate to vigorous physical activity, Active daily EE = energy expenditure > 3 Mets; Total daily EE = total energy expenditure

*Post-hoc effects for between group differences: groups with the same letter are not significantly different across time points
