Starling (1999): TEE = Total Energy Expenditure in kcal/day.
Staten (2001): TEE = Total Energy Expenditure in kJ/day, -ic = average total energy expenditure with RMR measured by indirect calorimetry, -mif = average total energy expenditure with RMR calculated using the Mifflin et al. Equation, -met = average total energy expenditure with RMR calculated using the MET conversion.
Tomioka (2011): Young old = age 65–74, old old = age 75–89.
Treuth (2004): GAQ score yesterday = summary score estimated from 18 physical activities reliably recalled and frequently performed on the previous day (yesterday) or usually. The GAQ summary scores were computed as the total MET-weighted score divided by the number of nonmissing items. Average counts/min: all counts measured between 6 AM to 12 midnight averaged per minute. Baseline: n = 197, follow-up: n = 168.
Trinh (2009): Dry season is baseline (n = 135). Measurements in wet season (n = 116) were performed 2 months after baseline during dry season. Sedentary time = time spent sitting or reclining. Mean (95 % LoA) = log-transformed average difference between the time spent in MVPA measured with GPAQ (averaged over dry and wet season) and accelerometer with 95 % limits of agreement.
Troped (2007): MPA = number of days participating in ≥ 30 min of moderate PA during past 7 days. VPA = number of days participating in ≥ 20 min of vigorous PA during past 7 days. Sensitivity = probability of the YRBS items correctly classifying students as meeting recommendations. Specificity = probability of YRBS items correctly classifying students as not meeting the recommended level of PA. Kappa range = range of kappa coefficients between Actigraph measures (accumulated minutes, minutes in bouts ≥ 5 min, minutes in bouts ≥ 10 min, sustained minutes of PA) and the YRBS measure. Cut points used are based on the Freedson age-dependent equation; METs = 2.757 + (0.0015*counts per minute) - (0.0896*age[yr]) - (0.000038*counts per minute*age[yr]).
Washburn (1999): Total PASE score was computed by multiplying the amount of time spent in each activity (hours/week) or participation (yes/no) in an activity by the empirically derived item weights and summing over all activities. Accelerometer readings are averaged over five-minute epoch periods.
Washburn (2003): Interviewer reliability tested: ICC = 0.85. TEE = Total Energy Expenditure, including sleep, in kJ/day. PAEE = Physical Activity Energy Expenditure, i.e. light, moderate, hard and very hard activities, excluding sleep.
Weston (1997): 1 Day = 1 day after school hours. TEE = Total relative Energy Expenditure in kcal/kg/day. EE = mean estimated rate of Energy Expenditure in kcal/kg/hr for the entire after school period, derived from both mode and intensity. %HRR = mean percent of heart rate range. HRR was calculated as HRmax - HRrest, where HRmax was estimated from the formula 220 - age, and HRrest was taken from the mean of the five lowest 1-min heart rates recorded during the measurement period. All heart rates (HRraw) were converted to a %HRR using the formula HRraw/HRR*100 and averaged to produce mean %HRR.
Wolin (2008): 1-Min bout = accelerometer bout lasting at least 1 minute. 10-Min bout = accelerometer bout lasting at least 10 minutes.
