Association of Self‐Reported Sleep Duration With All‐Cause and 
CVD
Unlike objective sleep, both short (≤4 hours) and long (>8 hours) self‐reported sleep duration on weekdays had a high rate of all‐cause mortality (Table The association of short (≤4 hours) and long (>8 hours) self‐reported sleep duration on weekdays with a high CVD mortality rate was also observed. We also found a J‐shaped curve between self‐reported sleep duration on weekdays and all‐cause mortality (The association of objective and self‐reported sleep duration with all‐cause and CVD mortality in men and women was also explored. There was an inverse association between the objective sleep duration and mortality in both men and women. A J‐shaped association was found between self‐reported sleep duration and mortality in both men and women (Figures
