Total sleep duration: the interval between sleep onset and sleep offset while the participant is asleep from polysomnography

nsrr_ttldursp_f1 under Harmonized/Polysomnography/Sleep Architecture in NUMOM2B variables

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).Harmonized by the NSRR team. Data collected with no EEGs. Source: :ttldursp_f1t3:

Sleep Onset: Clock time when the participant falls asleep from type III home sleep apnea test

begtimsp_f1t3 under Sleep Monitoring/Polysomnography/Sleep Architecture in NUMOM2B variables

Total estimated sleep duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type III home sleep apnea test

ttldursp_f1t3 under Sleep Monitoring/Polysomnography/Sleep Architecture in NUMOM2B variables

Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441)

Sleep Maintenance Efficiency: the proportion of estimated sleep duration in sleep period from type III home sleep apnea test

ttleffsp_f1t3 under Sleep Monitoring/Polysomnography/Sleep Architecture in NUMOM2B variables

Estimated sleep duration, providing an approximation of total sleep duration (i.e. total sleep time) inferred from analysis of non-EEG channels Zhao et al., 2017 (PMID:27707441). Sleep period is just the interval between sleep onset and sleep offset time.

Sleep Latency: the interval between lights-out/in-bed time and sleep onset from type III home sleep apnea test

Standard deviation of daily total sleep period during main sleep on weekdays from actigraphy

sawa100 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 on weekdays from actigraphy

sawa101 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep duration (i.e. total sleep time) is the interval between sleep onset and sleep offset time while asleep. This variable is similar to variable sawa36; however, sawa36 is calculated based on data generated by Actiware software before data cleaning and imputation.

Standard deviation of daily sleep duration on weekdays from actigraphy

sawa102 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep duration (i.e. total sleep time) is the interval between sleep onset and sleep offset time while asleep.

Average daily sleep onset latency on weekdays from actigraphy

sawa103 under Sleep Monitoring/Actigraphy in HCHS variables

Average daily duration of wake after sleep onset (WASO) on weekdays from actigraphy

sawa104 under Sleep Monitoring/Actigraphy in HCHS variables

Average daily sleep efficiency on weekdays from actigraphy

sawa107 under Sleep Monitoring/Actigraphy in HCHS variables

Sleep efficiency is the proportion of sleep duration (i.e. total sleep time, tst) in total rest period (i.e. rest interval) in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep. In this study, rest interval is the same as in-bed period.

Standard deviation of the daily sleep efficiency on weekdays from actigraphy

sawa108 under Sleep Monitoring/Actigraphy in HCHS variables

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

sawa112 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.

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

sawa113 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 weekdays from actigraphy

sawa120 under Sleep Monitoring/Actigraphy in HCHS variables

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

Average daily sleep onset time on weekdays from actigraphy

sawa127 under Sleep Monitoring/Actigraphy in HCHS variables

This variable is similar to variable SAWA43; however, SAWA43 is calculated based on data generated by Actiware software before data optimization
