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

sdsleepmidpointwe5 under Sleep Monitoring/Actigraphy in MESA variables

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

Standard deviation of the daily midpoint for sleep period in workdays from actigraphy

sdsleepmidpointwo5 under Sleep Monitoring/Actigraphy in MESA variables

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

Standard deviation of daily sleep period in all days from actigraphy

sdsleepperiodduration5 under Sleep Monitoring/Actigraphy in MESA variables

Sleep period (i.e. total sleep time, TST) is the interval between sleep onset time and sleep offset time in main sleep.

Standard deviation of daily sleep period in non-workdays from actigraphy

sdsleepperioddurationnw5 under Sleep Monitoring/Actigraphy in MESA variables

Sleep period (i.e. total sleep time, TST) is the interval between sleep onset time and sleep offset time in main sleep.

Standard deviation of daily sleep period in weekdays from actigraphy

sdsleepperioddurationwd5 under Sleep Monitoring/Actigraphy in MESA variables

Sleep period (i.e. total sleep time, TST) is the interval between sleep onset time and sleep offset time in main sleep.

sdsleepperioddurationwe5 under Sleep Monitoring/Actigraphy in MESA variables

Sleep period (i.e. total sleep time, TST) is the interval between sleep onset time and sleep offset time in main sleep.

Standard deviation of daily sleep period in workdays from actigraphy

sdsleepperioddurationwo5 under Sleep Monitoring/Actigraphy in MESA variables

Sleep period (i.e. total sleep time, TST) is the interval between sleep onset time and sleep offset time in main sleep.

Percentage of total sleep duration in non-supine position from type II polysomnography

nsupinep5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, conventionally called total sleep time.

REM Latency I: the interval between sleep onset and first REM (including wake) from type II polysomnography

rem_lat15 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

REM Latency II: the interval between sleep onset and first REM while asleep (excluding wake) from type II polysomnography

remlaiip5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Sleep Efficiency: the proportion of total sleep duration in in-bed period from type II polysomnography

slp_eff5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep, while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time. Conventionally, this variable could be described as the ratio between total sleep time (TST) and time in bed (TIB).

Sleep Latency: the interval between lights-out/in-bed time and sleep onset time from type II polysomnography

slp_lat5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Total Sleep Duration: the interval between sleep onset and sleep offset while the participant is asleep from type II polysomnography

slpprdp5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Conventionally this variable would be called total sleep time (TST)(i.e. total time spent in stage 1 or greater).

Sleep onset time from type II polysomnography

stonsetp5 under Sleep Monitoring/Polysomnography/Sleep Architecture in MESA variables

Conventionally this variable would be called the start of total sleep time (TST)(i.e. total time spent in stage 1 or greater).

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

nsrr_tst_f1 under Harmonized/Polysomnography/Sleep Architecture in APOE 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. Source: :tst:

Sleep Efficiency: the ratio of sleep duration (i.e., total sleep time) to in-bed period (i.e., time in bed) from type I polysomnography

sleep_efficiency under Sleep Monitoring/Polysomnography/Sleep Architecture in APOE variables

Sleep duration is the interval between sleep onset time and lights on/out-bed time while asleep (i.e. total sleep time, TST), while in-bed period is the interval between lights off/in-bed time and lights on/out-bed time (i.e. time in bed, TIB). Percentage of time in bed that was spent sleeping, or the ratio of total sleep time to total time in bed, expressed as a percentage. Source: :tst: and :tib:

Total Sleep Duration: the interval between sleep onset time and lights on/out-bed time while the participant is asleep from type I polysomnography

tst under Sleep Monitoring/Polysomnography/Sleep Architecture in APOE variables

Conventionally, this would be called total sleep time (TST) (i.e. total time spent in stage 1 or greater).
