Key Points
- To explore the correlation between self-reported sleep duration and objective measurements.
- Population-based sample of middle-aged adults
- Comparison of subjective sleep reports with actigraph-measured sleep
- Analysis of bias in self-reported sleep data
- Self-reported sleep duration is moderately correlated with actigraphy measurements
- Systematic over-reporting is evident in self-reported data
- True associations between sleep and health may differ from earlier studies
Abstract
In a population-based sample of middle-aged adults, subjective reports of habitual sleep are moderately correlated with actigraph-measured sleep, but are biased by systematic over-reporting. The true associations between sleep duration and health may differ from previously reported associations between self-reported sleep and health.
