Association of Objective Sleep Duration With All‐Cause and 
deaths
CVD
During an average of 10.7±3.0 years of follow‐up, 1172 (23.3%) all‐cause deaths were identified, including 359 (7.1%) CVD deaths. Individuals with objective sleep duration of ≤4 hours (45.9%), 4 to 5 hours (31.3%), 5 to 6 hours (25.0%), and 6 to 7 hours (21.9%) had a higher all‐cause mortality than those with a sleep duration of 7 to 8 hours (13.5%). All‐cause mortality was similar for the objective sleep duration at 7 to 8 hours and >8 hours. Unadjusted Kaplan–Meier analysis showed lower overall survival among participants with a shorter objective sleep duration (Figure
