Sleep Maintenance Efficiency: the proportion of sleep duration in sleep period from type I polysomnography
slp_maint_eff under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Sleep duration (i.e., total sleep time, TST) is the interval between sleep onset and sleep offset time while asleep. Sleep period is the interval between sleep onset and sleep offset time.
Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography
slpprdp under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
Percentage duration of sleep in supine position from type I polysomnography
supinep under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Percent of sleep time in supine body position [100*(number of minutes of sleep in supine body position) / (Total Sleep Time (TST))]
Percentage duration of sleep in stage 3/4 sleep from type I polysomnography
times34p under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Percent of sleep time in stage 3-4 [100*(number of minutes scored as stage 3-4) / (Total Sleep Time (TST))]
Wake After Sleep Onset: the total duration between sleep onset and lights-on/out-bed time while being awake from type I polysomnography
waso under Sleep Monitoring/Polysomnography/Sleep Architecture in CHAT variables
Total amount of time spent awake after going to sleep [(time in bed) - (sleep latency) - (Total Sleep Time (TST))]
Percentage of snore time in sleep (decibel (dB) level 5)
pdb5slp under Sleep Monitoring/Polysomnography/Sound Events in CHAT variables
[(total time snore at decibel (dB) level 5) / (Total Sleep Time (TST))] * 100
Percentage of total sleep duration (i.e., total sleep time, TST) in stage 1 from polysomnography

Average daily sleep efficiency in all days from actigraphy
avgefficiency5 under Sleep Monitoring/Actigraphy in MESA 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.
Average daily sleep efficiency in non-workdays from actigraphy
avgefficiencynw5 under Sleep Monitoring/Actigraphy in MESA 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.
Average daily sleep efficiency in weekdays from actigraphy
avgefficiencywd5 under Sleep Monitoring/Actigraphy in MESA 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.
Average daily sleep efficiency in weekends from actigraphy
avgefficiencywe5 under Sleep Monitoring/Actigraphy in MESA 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.
