Abstract

Background Long-term sleep deprivation is common in today's society. Recent experiments have demonstrated that short-term sleep deprivation in healthy subjects results in adverse physiologic changes, including a decreased glucose tolerance and an increased blood pressure. However, the long-term health consequences of long-term sleep deprivation are unclear. The objective of this study was to determine whether decreased sleep duration (from self-reports) is associated with an increased risk of coronary events. Methods We studied a cohort of 71 617 US female health professionals (aged 45-65 years), without reported coronary heart disease (CHD) at baseline, who were enrolled in the Nurses' Health Study. Subjects were mailed a questionnaire in 1986 asking about daily sleep duration. Subjects were followed up until June 30, 1996, for the occurrence of CHD-related events. We assessed the relationship between self-reported sleep duration and incident CHD. Results A total of 934 coronary events were documented (271 fatal and 663 nonfatal) during the 10 years of follow up. Age-adjusted relative risks (95% confidence intervals) of CHD (with 8 hours of daily sleep being considered the reference group) for individuals reporting 5 or fewer, 6, and 7 hours of sleep were 1.82 (1.34-2.41), 1.30 (1.08-1.57), and 1.06 (0.89-1.26), respectively. The relative risk (95% confidence interval) for 9 or more hours of sleep was 1.57 (1.18-2.11). After adjusting for various potential confounders, including snoring, body mass index, and smoking, the relative risks of CHD (95% confidence intervals) for individuals reporting 5 or fewer, 6, and 7 hours of sleep were 1.45 (1.10-1.92), 1.18 (0.98-1.42), and 1.09 (0.91-1.30), respectively. The relative risk (95% confidence interval) for 9 or more hours of sleep was 1.38 (1.03-1.86). Conclusion Short and long self-reported sleep durations are independently associated with a modestly increased risk of coronary events.

  • Accumulating evidence points to an association between sleep curtailment and obesity and type 2 diabetes.

    “Accumulating evidence has pointed to an association between sleep curtailment and obesity,4,5 type 2 diabetes,6–9 and possibly mortality (see Ref. 10 for a review).”
  • In the Nurses' Health Study, long (≥9 hours per night) self-reported sleep duration was associated with increased risk of incident coronary heart disease over 10 years (RR 1.38; 95% CI 1.03-1.86) compared to sleeping 8 hours per night.

    “The Nurses’ Health Study found a significantly increased risk of incident coronary heart disease over 10 years associated with short (≤5 hours per night) self-reported sleep duration (risk ratio 1.45; 95% CI: 1.1–1.92) and long (≥9 hours per night) self-reported sleep duration (risk ratio 1.38; 95% CI: 1.03–1.86) compared to those sleeping 8 hours per night [211].”

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.
