abstract = {Sleep duration is a novel and potentially modifiable risk factor for cancer. We evaluated the association
of self-reported sleep duration and daytime napping with odds of colorectal and gastric cancer. We
included 2008 incident colorectal cancer cases, 542 gastric cancer cases and 3622 frequency-matched
population controls, recruited in the MCC-Spain case–control study (2008–2013). Sleep information,
socio-demographic and lifestyle characteristics were obtained through personal interviews.
Multivariable adjusted logistic regression models were used to estimate odds ratios (OR) with 95%
confidence intervals (CI) for cancer, across categories of sleep duration (≤ 5, 6, 7, 8, ≥ 9 hours/day),
daytime napping frequency (naps/week) and duration (minutes/nap). Compared to 7 hours of sleep,
long sleep was associated with increased odds of colorectal (
OR≥9 hours: 1.59; 95%CI 1.30–1.94) and
gastric cancer (
OR≥9 hours: 1.95; 1.37–2.76); short sleep was associated with increased odds of gastric
cancer (
OR≤5 hours: 1.32; 0.93–1.88). Frequent and long daytime naps increased the odds of colorectal
(
OR6–7 naps/week, ≥30 min: 1.32; 1.14–1.54) and gastric cancer (
OR6–7 naps/week, ≥30 min: 1.56; 1.21–2.02). Effects
of short sleep and frequent long naps were stronger among participants with night shift-work history.
Sleep and circadian disruption may jointly play a role in the etiology of colorectal and gastric cancer.},
