Wear time and physical activity according to visual inspection or wear log protocol in 197 women, Women’s Health Study

	Visual Inspection	Wear Log	P Difference

Wear time (min/d)	900.0 (848.3, 950.3)	898.7 (846.9, 947.4)	0.90
Total counts per day (in 1000s)	470.5 (372.5, 578.1)	468.0 (372.5, 574.7)	0.46
Sedentary behavior (min/d)	493.3 (443.4, 574.1)	493.3 (442.3, 574.1)	0.30
Light activity (min/d)	368.0 (312.7, 417.6)	368.0 (312.7, 415.6)	0.43
Moderate-to-vigorous activity (min/d)	20.7 (8.9, 37.4)	20.0 (8.9, 37.4)	0.95
Steps per day	5173.6 (3852.1, 7331.9)	5084.8 (3836.1, 7384.6)	0.86

Estimates were calculated using accelerometer data from wear days, as determined by the particular protocol. Data from wear days, as identified under each protocol, were processed using the Choi wear time algorithm.(3, 4) Estimates are medians (25th percentile, 75th percentile) unless otherwise specified. P-value for difference between visual inspection and wear log was calculated by Wilcoxon Signed-Rank test.
