Correlates of sleep quality in midlife and beyond: a machine learning analysis

摘要

Objectives: In older adults, traditional metrics derived from polysomilography (PSG) are not well correlated with subjective sleep quality. Little is known about whether the association between PSG and subjective sleep quality changes with age, or whether quantitative electroencephalography (qEEG) is associated, with sleep quality. Therefore, we examined the relationship between subjective sleep quality and objective sleep characteristics (standard PSG and qEEG) across middle to older adulthood.
