Sleep efficiency (SE) is the ratio between the time a person spends asleep, and the total time dedicated to sleep (i.e. both sleeping and attempting to fall asleep or fall back asleep). It is given as a percentage. [1] SE of 80% or more is considered normal/healthy with most young healthy adults displaying SE above 90%.
Pregnancy brings about significant and dynamic physiological changes that can impact sleep and contribute to sleep disorders.These changes encompass structural alterations that may affect the length and quality of sleep, disrupt breathing during sleep, and metabolic shifts that raise the risk of restless legs syndrome.
The component scores consist of subjective sleep quality, sleep latency (i.e., how long it takes to fall asleep), sleep duration, habitual sleep efficiency (i.e., the percentage of time in bed that one is asleep), sleep disturbances, use of sleeping medication, and daytime dysfunction. Each item is weighted on a 0–3 interval scale.

[3] Certain questions in the scale were shown to be better predictors of specific sleep disorders, though further tests may be required to provide an ...
