ABSTRACT
STUDY OBJECTIVES:
To examine the associations between sleep duration, continuity, timing, and mortality using actigraphy among adults.METHODS:
Data were from a cohort of 88 282 adults (40-69 years) in UK Biobank that wore a wrist-worn triaxial accelerometer for 7 days. Actigraphy data were processed to generate estimates of sleep duration and other sleep characteristics including wake after sleep onset (WASO), number of 5-minute awakenings, and midpoint for sleep onset/wake-up and the least active 5 hours (L5). Data were linked to mortality outcomes with follow-up to October 31, 2021. We implemented Cox models (hazard ratio, confidence intervals [HR, 95% CI]) to quantify sleep associations with mortality. Models were adjusted for demographics, lifestyle factors, and medical conditions.RESULTS:
Over an average of 6.8 years 2973 deaths occurred (1700 cancer, 586 CVD deaths). Overall sleep duration was significantly associated with risk for all-cause (pâ <â 0.01), cancer (pâ <â 0.01), and CVD (pâ =â 0.03) mortality. For example, when compared to sleep durations of 7.0 hrs/d, durations of 5 hrs/d were associated with a 29% higher risk for all-cause mortality (HR 1.29 [1.09, 1.52]). WASO and number of awakenings were not associated with mortality. Individuals with L5 early or late midpoints (<230 orâ ≥â 330) had a ~20% higher risk for all-cause mortality, compared to those with intermediate L5 midpoints (300-329; pâ ≤â 0.01; e.g. HR ≥ 330 1.19 [1.07, 1.32]).CONCLUSIONS:
Shorter sleep duration and both early and late sleep timing were associated with a higher mortality risk. These findings reinforce the importance of public health efforts to promote healthy sleep patterns in adults.Palavras-chave
