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.

HCHS variables
Sleep maintenance efficiency is the ratio between sleep duration (i.e. total sleep time, tst) and sleep period in main sleep. Sleep duration is the interval between sleep onset time and sleep offset time while asleep, while sleep period is the interval between sleep onset time and sleep offset time. This variable is similar to variable sawa34; however, sawa34 is derived from Actiware variable sawa24 before data optimization.

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: :slpprdp: at Visit 8

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.
