Abstract

STUDY OBJECTIVES: To investigate the relationship between sleep duration and insomnia severity and the risk of all-cause death and cardiovascular disease (CVD) events. DESIGN: Prospective cohort study. SETTING: Community-based. PARTICIPANTS: A total of 3,430 adults aged 35 years or older. INTERVENTION: None. MEASUREMENTS AND RESULTS: During a median 15.9 year (interquartile range, 13.1 to 16.9) follow-up period, 420 cases developed cardiovascular disease and 901 cases died. A U-shape association between sleep duration and all-cause death was found: the age and gender-adjusted relative risks (95% confidence interval [CI]) of all-cause death (with 7 h of daily sleep being considered for the reference group) for individuals reporting < or = 5 h, 6 h, 8 h, and > or = 9 h were 1.15 (0.91-1.45), 1.02 (0.85-1.25), 1.05 (0.88-1.27), and 1.43 (1.16-1.75); P for trend, 0.019. However, the relationship between sleep duration and risk of CVD were linear. The multivariate-adjusted relative risk (95% CI) for all-cause death (using individuals without insomnia) were 1.02 (0.86-1.20) for occasional insomnia, 1.15 (0.92-1.42) for frequent insomnia, and 1.70 (1.16-2.49) for nearly everyday insomnia (P for trend, 0.028). The multivariate adjusted relative risk (95% CI) was 2.53 (1.71-3.76) for all-cause death and 2.07 (1.11-3.85) for CVD rate in participants sleeping > or = 9 h and for those with frequent insomnia. CONCLUSIONS: Sleep duration and insomnia severity were associated with all-cause death and CVD events among ethnic Chinese in Taiwan. Our data indicate that an optimal sleep duration (7-8 h) predicted fewer deaths.

  • In a US study of over 3,400 men and women aged 35 or older, those who complained of insomnia every day had a significant increase in cardiovascular disease events compared to those without any insomnia complaint (RR 1.78, 95% CI 1.03-3.08).

    “A study in the US of over 3,400 men and women 35 years of age or older reported a significant increase of cardiovascular disease events in those who complained of insomnia every day compared to those without any insomnia complaint (RR: 1.78, 95%CI 1.03–3.08) [214].”
  • A few studies examined cardiovascular disease mortality in relation to self-reported sleep duration, but none found a significant association in fully adjusted models.

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.
