Table 2 Summary of variety in objective measures characteristics: organised by the output units, citation, a brief of the tools and inclusion and exclusions criteria
The output unit of measured COAMB | Citation | Tools used + duration in survey Data registry (epoch) Temporal measures (if present) (i.e. weekdays vs weekends or time segments of the day before and after school) | Inclusion/exclusion of collected GPS COAMB data |
|---|---|---|---|
Intensity MVPA | [33] | Accelerometer for 8 consecutive days Epoch not reported during non-school hours Compared outside school hours for weekdays and weekends (before school [6 am] to school first bell) and evening (6–9 pm) | 4 weekdays and at least 1 weekend for inclusion; data were excluded for any day if fewer than 10,000 and over 20 million steps counted to calculate MVPA |
[45] | Accelerometer for 7 days 30-s epochs – | 10 h wear time for inclusion with no more than 20 min of consecutive zero counts and at least 3 days of accepted measures | |
[36] | Accelerometer for 7 days 5-secs epochs Compared outside school hours for weekdays and weekends | 10 h wearing time for 3 weekdays and 1 weekend day for inclusion in the analysis, MVPA > 3,581 counts per minute | |
[41] | Accelerometer for 7 days Every 749/30-s epochs), + GPS 10-s epochs (cleaned and resampled to 30-s Compared outside school hours for weekdays and weekends (before school hours 8:00–8:45 am, after school 2:30–7:00 pm and weekends) + travel diary | Accelerometer outside school hours, 3 h or more of data (weekdays) and 7 h of data (weekend) GPS inclusion of data was not reported | |
Activity space | [49] | Pedometer for 9 days and mapping destination Epoch not reported – | Data with 1,000–30,000 steps daily included At least 4 days of data First and last day of measures removed from the analysis |
Active transportation | [16] | GPS in a wearable watch for 7 days – | Data excluded with < 10 h GPS data and participants with < 4 days of 10 h GPS data (adopted from accelerometer standard measures) |
Proximity | [28] | GPS + mobility diary for 7 days 5-s epochs – | No report of details |
Neighbourhood activity space | [52] | GPS for 7 days Recorded each second Compared outside school hours for weekdays and weekends | 3 h of out-of-school wearing time GPS (two weekdays) and 4 h of one weekend day Guided by accelerometer for inclusion |
Active outdoor play (daily average) | [40] | GPS + accelerometer for 7 days 15-secsepochs | Remove < 10 h of accelerometer or GPS wear time or less than 15-s epochs |
