Average number of wake bouts (continuous periods of wake) between sleep onset and sleep offset in main sleep on weekends from actigraphy

sawa160 under Sleep Monitoring/Actigraphy in HCHS variables

Wake bouts is also referred to as "nocturnal awakenings". There are always comparable number of wake bouts to sleep bouts.

Average sleep duration per nap on weekends from actigraphy

sawa167 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep duration is the interval between sleep onset and sleep offset time while asleep.

Average exposure to white light in main sleep over all days from actigraphy

sawa17 under Sleep Monitoring/Actigraphy in HCHS variables

This is the average white light intensity, in lux, between sleep onset and sleep offset times across all main rest intervals with sleep, as generated by Actiware before data optimization.

Average daily sleep onset time on weekends from actigraphy

sawa174 under Sleep Monitoring/Actigraphy in HCHS variables

This variable is similar to variable SAWA44; however, SAWA44 is calculated based on data generated by Actiware software before data optimization

Standard deviation of the daily sleep onset time on weekends from actigraphy

sawa175 under Sleep Monitoring/Actigraphy in HCHS variables

Average duration of daily sleep period from actigraphy

sawa18 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep period is the interval between sleep onset and sleep offset time.This variable is similar to sawa52; however, sawa18 is generated by Actiware software before data optimization.

Average daily mid-point for sleep period in main sleep on weekends from actigraphy

sawa182 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep period is the interval between sleep onset and sleep offset time.

Standard deviation of the daily midpoint for sleep period in main sleep on weekends from actigraphy

sawa183 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep period is the interval between sleep onset and sleep offset time.

Average daily total sleep duration in main sleep and naps combined on workdays from actigraphy

sawa206 under Sleep Monitoring/Actigraphy in HCHS variables

sleep bouts are continuous blocks, one or more epochs in duration, with each epoch of each block scored as "sleep", between the start time and the end time of the given interval.
