Hello. I'm trying to find out how to analyze the accelerometer-derived data in the NHANES 2011-2014 cycles (wrist-worn triaxial accelerometer). I want to transform the data to steps/day, but I'm not sure if there are equations to do it (e.g., from counts/minute to steps/minute), or do I need specialized software (e.g., Actilife)? I've read some articles analyzing the NHANES 2003-2006 cycles, but they used uniaxial accelerometers.
What article(s) would you suggest for me to understand how to proceed?
Best wishes.
