Most primary care patients experience a significant gap between their perceived and ideal sleep duration. This discrepancy is linked to insomnia severity, older age, and lifestyle choices, highlighting a need for interventions.
Area of Science:
- Sleep Medicine
- Primary Care Research
- Psychology
Background:
- A significant portion of the population experiences a discrepancy between how much sleep they perceive they get and how much they ideally need.
- Understanding the factors contributing to this sleep expectation-reality gap is crucial for improving patient well-being.
Purpose of the Study:
- To quantify the difference between perceived and ideal sleep duration in primary care patients.
- To identify demographic, lifestyle, and psychological factors associated with this sleep discrepancy.
Main Methods:
- A cross-sectional survey of 300 primary care patients assessed demographics, sleep perceptions, and insomnia severity using the Insomnia Severity Index (ISI).
- Sleep discrepancy was calculated as the difference between perceived and ideal sleep duration.
- Statistical analyses included Wilcoxon signed-rank tests, Spearman's correlations, and multiple linear regression.
Main Results:
- 81.3% of participants reported a significant sleep discrepancy, with perceived sleep duration (6.39 ± 1.36 h) being substantially lower than ideal (8.07 ± 0.75 h).
- Higher ISI scores (indicating greater insomnia severity) were strongly correlated with larger sleep discrepancies (r = -0.476, p < 0.001).
- Insomnia severity, higher BMI, cola consumption, and older age were significant predictors of sleep discrepancy, explaining 27.7% of the variance.
Conclusions:
- A considerable gap exists between perceived and ideal sleep duration among primary care patients.
- Insomnia severity, older age, and certain lifestyle factors are key contributors to this discrepancy.
- Cognitive-behavioral interventions targeting maladaptive sleep expectations may enhance sleep satisfaction and reduce distress in primary care settings.
