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.
