- NHANES/NNYFS Combined Sample 2012 – Physical Activity Monitor – Ambient Light Raw Data (C_PAXLUX 2012)
Updated Data
The summary ambient light (lux) measures (i.e., PAXLXSH) previously included in the following Physical Activity Monitor (PAM) Minute Summary Files were erroneously described as the ‘sum’ of lux measures at the minute level whereas the values reported are the ‘mean’ lux measures for the minute. The files were updated with the variable PAXLXSH renamed as PAXLXMM and description corrected. No change was made to the data points reported. In addition, the descriptions for the codes associated with the quality check flags were also updated to clarify the data issues denoted by these flags.
