Potential corner case cautions regarding publicly available implementations of the National Cancer Institute’s nonwear/wear classification algorithm for accelerometer data

Prevalence in NHANES 2003–2004.
The frequency of A-type and B-type patterns found in the NHANES 2003–2004 physical activity monitoring dataset is shown for different ranges of T. A-type patterns represent NCINW’s nonwear count allowance and consist of hours with ≥ T counts and classified as nonwear according to NCINW. B-type patterns comprise hours with between 1 and T counts that are classified as wear. Results are from examination of 6,827 participants.
