Abstract

STUDY OBJECTIVES: Although sleep curtailment has become widespread in industrialised societies, little work has examined the effects on mortality of change in sleep duration. We investigated associations of sleep duration and change in sleep duration with all-cause, cardiovascular, and non-cardiovascular mortality. DESIGN: Prospective cohort study. Data are from baseline (Phase 1, 1985-88) and Phase 3 (1991-93), with mortality follow-up of 17 and 12 years respectively. SETTING: The Whitehall II study of 10,308 white-collar British civil servants aged 35-55 at baseline. PARTICIPANTS: 9781 participants with complete data were included in the analyses at Phase 1, and 7729 of the same participants were included in the analyses at Phase 3 and the analyses of change in sleep duration. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: U-shaped associations were observed between sleep (< or =5, 6, 7, 8, > or =9 hours) at Phase 1 and Phase 3 and subsequent all-cause, cardiovascular, and non-cardiovascular mortality. A decrease in sleep duration among participants sleeping 6, 7, or 8 hours at baseline was associated with cardiovascular mortality, hazard ratio 2.4 (95% confidence intervals 1.4-4.1). However, an increase in sleep duration among those sleeping 7 or 8 hours at baseline was associated with non-cardiovascular mortality, hazard ratio 2.1 (1.4-3.1). Adjustment for the socio-demographic factors, existing morbidity, and health-related behaviours measured left these associations largely unchanged. CONCLUSIONS: This is the first study to show that both a decrease in sleep duration and an increase in sleep duration are associated with an increase in mortality via effects on cardiovascular death and non-cardiovascular death respectively.

  • Self-reported sleep duration is widely used in epidemiologic studies and is the basis of research on the relation between sleep duration and mortality.

    “Self-reported sleep duration is widely used in epidemiologic studies and is the basis of research on the relation between sleep duration and mortality (13)(14)(15)(16)(17)(18)(19).”
  • Older ages, current smoking and former smoking, and alcohol consumption are associated with short sleep in prior work, but they are also associated with long sleep in our data.

    “Older ages (7,20,21), current smoking and former smoking, and alcohol consumption (19,36,38,39) are associated with short sleep in prior work, but they are also associated with long sleep in our data”
  • Young children, being unmarried, working long hours, overweight and obesity, and measures of poor health including acute and chronic respiratory conditions, pain, and anxiety increase the odds of short sleep and have a null or inverse association with long sleep.

    “Young children, being unmarried (19,26), working long hours (11,27,28), overweight and obesity (3-5), and measures of poor health (13,14,16,20,37,38,40) including acute and chronic respiratory conditions, pain, and anxiety increase the odds of short sleep and have a null or inverse association with long sleep.”

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.
