Our findings indicate that data from self-report correspond only weakly to PSG-measured sleep duration, and only moderately with 5-day actigraphy measurements, underscoring the need to very cautiously extrapolate findings from studies using different measurement instruments.

Furthermore, self-reported sleep duration less accurately estimates objective sleep in blacks compared with whites; larger reporting bias and poorer calibration of estimates would reduce the ability to identify significant associations between sleep duration and health among blacks compared with whites.
