Self-Reported and Measured Sleep Duration: How Similar Are They?
Open accessAbstract
BACKGROUND: Recent epidemiologic studies have found that self-reported duration of sleep is associated with obesity, diabetes, hypertension, and mortality. The extent to which self reports of sleep duration are similar to objective measures and whether individual characteristics influence the degree of similarity are not known. METHODS: Eligible participants at the Chicago site of the Coronary Artery Risk Development in Young Adults Study were invited to participate in a 2003-2005 ancillary sleep study; 82% (n = 669) agreed. Sleep measurements collected in 2 waves included 3 days each of wrist actigraphy, a sleep log, and questions about usual sleep duration. We estimate the average difference and correlation between subjectively and objectively measured sleep by using errors-in-variables regression models. RESULTS: Average measured sleep was 6 hours, whereas the average from subjective reports was 6.8 hours. Subjective reports increased on average by 34 minutes for each additional hour of measured sleep. Overall, the correlation between reported and measured sleep duration was 0.47. Our model suggests that persons sleeping 5 hours over-reported their sleep duration by 1.2 hours, and those sleeping 7 hours over-reported by 0.4 hours. The correlations and average differences between self-reports and measured sleep varied by health, sociodemographic, and sleep characteristics. CONCLUSION: 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.

In the citing paper
“Self-reported sleep duration often differs considerably from objective measures of sleep duration, and may underestimate or overestimate sleep duration compared to these other methods.121–123”
In the citing paper
“However, subjectively and objectively assessed sleep parameters can differ substantially (26, 327), which must be considered when evaluating sleep.”
From The Sleep-Immune Crosstalk in Health and Disease (2019) · cites this paper as [327]
In the citing paper
“sleep duration evaluated by self-report questionnaires and diaries may not agree with the results of actigraphy and PSG. In healthy populations, self-reported sleep duration appears to be longer compared with actigraphy estimates, while in populations with sleep disturbances, self-reported sleep duration tends to be shorter”
From The Sleep-Immune Crosstalk in Health and Disease (2019) · cites this paper as [327]
In the citing paper
“Epidemiologic studies, while typically more generalizable, carry methodological limitations such as inconsistent definitions of ‘short’ and ‘long’ sleep duration categories, inconsistent assessments (e.g., differently-worded survey items)[17], variable measurement techniques (e.g., diaries, actigraphy, polysomnography)[38], and occasionally non-representative samples”
From Habitual sleep duration associated with self-reported and objectively determined cardiometabolic risk factors (2014) · cites this paper as [38]
In the citing paper
“Despite this limitation, sleep duration has been shown to correlate reasonably well with objectively measured sleep (r=0.47)[38].”
From Habitual sleep duration associated with self-reported and objectively determined cardiometabolic risk factors (2014) · cites this paper as [38]
In the citing paper
“Self-reported sleep duration has been only moderately associated with objectively-estimated sleep duration [122, 123].”
From Association between sleep deficiency and cardiometabolic disease: implications for health disparities (2016) · cites this paper as [122]
In the citing paper
“These observational studies all relied on self-reported sleep, which may not be very accurate (13).”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
