OBJECTIVE/BACKGROUND: Sleep plays a central role in maintaining health and
cognition. In most epidemiologic studies, sleep is evaluated by self-report
questionnaires but several reports suggest that these evaluations might be less
accurate than objective measures such as polysomnography or actigraphy.
Determinants of the discrepancy between objective and subjective measures remain
to be investigated. The aim of this pilot-study was to examine the role of mood
states in determining the discrepancy observed between objective and subjective
measures of sleep duration in older adults.
PATIENTS/METHODS: Objective sleep quantity and quality were recorded by
actigraphy in a sample of 45 elderly subjects over at least three consecutive
nights. Subjective sleep duration and supplementary data, such as mood status and
memory, were evaluated using ecological momentary assessment (EMA).
RESULTS: A significant discrepancy was observed between EMA and actigraphic
measures of sleep duration (p < 0.001). The magnitude of this difference was
explained by the patient's mood status (p = 0.020). No association was found
between the magnitude of this discrepancy and age, sex, sleep quality or memory
performance.
CONCLUSION: The discrepancy classically observed between objective and subjective
measures of sleep duration can be explained by mood status at the time of
awakening. These results have potential implications for epidemiologic and
clinical studies examining sleep as a risk factor for morbidity or mortality.
