Sleep duration and mortality: a systematic review and meta‐analysis

摘要: Summary Epidemiologic studies have shown that sleep duration is associated with overall mortality. We conducted a systematic review of the associations between and all-cause cause-specific PubMed was systematically searched up to January, 2008 identify examining association mortality (both cause-specific) among adults. Data were abstracted serially in standardized manner by two reviewers analyzed using random-effects meta-analysis. Twenty-three assessing identified. All examined measured participant self-report. Among 16 which had similar reference categories reported sufficient data on short for meta-analyses, pooled relative risk (RR) 1.10 [95% confidence interval (CI): 1.06, 1.15]. For cardiovascular-related cancer-related mortality, RRs 1.06 (95% CI: 0.94, 1.18) 0.99 0.88, 1.13), respectively. Similarly, 17 reporting long comparing sleepers medium 1.23 1.17, 1.30) 1.38 1.13, 1.69) 1.21 1.11, 1.32) Our findings indicate both are at increased Further research objective measures needed fully characterize these associations.
