Development and testing of the BONES physical activity survey for young children

Table 4 Descriptive statistics of the BONES physical activity survey and accelerometry data (n = 34)

*Indicators*	Mean ± SD
BONES physical activity survey (PAS):
Moderate-high MET score	22.62 ± 10.07
High MET score	16.15 ± 7.41
Weight-bearing score^a	4.28 ± 2.19
Accelerometry (Sum of two days):
Total counts	633302.50 ± 179639.90
Total minutes worn	1494.03 ± 171.94
Counts/minute	854.69 ± 232.90
Minutes of:
I: Moderate activity (3-6 METs)	260.71 ± 77.18
II: Vigorous activity (6-9 METs)	20.25 ± 12.96
III: Very vigorous activity (> 9 METs)	5.49 ± 6.36
I + II + III: Total moderate-vigorous PA; (MPVA; ≥ 3 METs)	286.44 ± 88.09
II + III: Total vigorous PA (VPA; ≥ 6 METs)	25.74 ± 17.54

PAS: MET: Metabolic equivalent time; SD: Standard deviation; PA: Physical activities
^a Weight-bearing score was calculated by adding the weight-bearing factor (WBF) of the reported activities (See Table 1)
