Cardon [15] 2004 Belgium | 51 boys, 41 girls; elementary school children; 6.5-12.7 years | Steps/day: Yamax Digiwalker SW-200, Yamax Corp, Japan MVPA: self-report questionnaire | 7 days | Linear regression equation to predict steps/day from self-reported 60 minutes in MVPA | Total: 13,130 steps/day = 60 minutes MVPA Boys: 15,340 steps/day = 60 minutes MVPA Girls: 11,317 steps/day = 60 minutes MVPA |
Rowlands [16] 2005 UK | 13 boys, 13 girls; primary school children; 8,3 to 10.8 years | Steps/day: Yamax Digi-Walker DW-200, Yamasa, Tokyo, Japan MVPA: Tritrac-R3D, models T303 and T303A, Professional Products, Reining International, Madison, WI | 5 weekdays and 1 weekend day | Sensitivity/specificity analysis of various thresholds to ascertain likelihood of attaining 60 minutes of accelerometer-determined MVPA | Boys: 18,000 steps/day = 60 minutes MVPA Girls: 15,000 steps/day = 60 minutes MVPA |
Beighle [51] 2006 USA | 256 boys, 334 girls; elementary school children; 9.2 ± 1.8 years | Steps/day and Activity Time*: MLS 2505, Walk4Life, Ind., Plainfield, IL | 4 weekdays | Linear regression to predict pedometer-determined daily activity time from daily step count | 5,000 steps/day = 64.5 minutes of activity 10,000 steps/day = 114.5 minutes of activity 12,000 steps/day = 134.5 minutes of activity 15,000 steps/day = 164.5 minutes of activity |
Cardon [49] 2007 Belgium | 37 boys, 39 girls; preschool children; 4 to 5.9 years | Steps/Day: Yamax Digiwalker SW-200, Yamax Corp., Japan MVPA: MTI Actigraph, 7164 (Fort Walton Beach, FL) | 2 weekdays and 2 weekend days | Regression equation to predict steps/day from accelerometer-determined time (60 minutes) in MVPA | 13,874 steps/day = 60 minutes MVPA |
Adams [52] 2009 USA | 12 boys, 28 girls; Overweight adolescents recruited through primary care providers; 11 to 16 years | Steps and MVPA: Actigraph 7164 | 7 days | ROC to determine steps/day related to achieving 60 minutes accelerometer-determined MVPA; two definitions of moderate intensity used | MVPA defined at least 3 METs: 9,930 steps/day = 60 minutes MVPA MVPA defined at least 4 METs: 11,714 steps/day = 60 minutes MVPA |
Tanaka [50] 2009 Japan | 127 boys, 85 girls; kindergarten/nursery school children; 4.5 to 6.8 years | Steps/day: Lifecorder EX, Suzuken, Nagoya MVPA: ActivTracer, GMS, Tokyo | 4 weekdays and 2 weekend days | Linear regression to predict steps/day from triaxial accelerometer-determined time (60, 100, and 120 minutes) in MVPA | 9,934 steps/day = 60 minutes MVPA 12,893 steps/day = 100 minutes MVPA 14,373 steps/day = 120 minutes MVPA |
Olds et al.[53] 2010 Australia | 129 boys, 168 girls; 9 to 16 years | New Lifestyles 1000 | randomly chosen day of six days | Linear regression equation to predict self-reported MVPA from steps/day | 1 minute MVPA = 103 steps; by extrapolation 60 minutes would approximately equal 6180 steps (taken over and above lifestyle activities) |
