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

In older adults, traditional metrics derived from polysomnography (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 assessment of EEG (qEEG) is associated with sleep quality. We therefore examined the relationship between subjective sleep quality and objective sleep characteristics (standard polysomnography and qEEG) across middle to older adulthood.
