We assessed the association between sleep duration and cancer incidence and mortality among Japanese adults using data from six population-based cohorts with 271 694 participants. During a total follow-up period of about 5.9 million person-years, we identified 40 751 incident cancer cases and 18 323 cancer deaths. We computed study-specific hazard ratios (HRs) and 95% confidence intervals (CIs) using Cox proportional hazards regression models and pooled the estimates using random-effects meta-analysis. Sleep duration of ?10 hours (vs 7 hours) was associated with increased risk of cancer incidence among women (HR 1.19, 95% CI 1.02-1.38), but not men, and increased risk of cancer mortality among men (HR 1.18, 95% CI 1.00-1.39) and women (HR 1.44, 95% CI 1.20-1.73). Sleep duration of ?5 hours (vs 7 hours) was not associated with cancer incidence and mortality. However, among postmenopausal women, sleep durations of both ?5 and ?10 hours (vs 7 hours) were associated with an increased risk of cancer mortality. Among Japanese adults, sleep duration of ?10 hours is associated with increased risk of cancer incidence and mortality among women and cancer mortality among men.抄録：英語フィールド
