Sex differences in sleep regularity and its associations with mortality

Mark É. Czeisler, Josh Leota, Flora Le, Prashant Rao et autres

Abstract In characterizing sleep and circadian health, the day–to–day regularity of sleep-wake timing strongly predicts health outcomes, outperforming short sleep duration in prospective associations with mortality and new-onset disease (1, 2). It is unknown whether biological (e.g., sleep and circadian physiology) and …

Abstract 4349201: Differential Associations by Sex Between Sleep-Wake Regularity and All-Cause and Cardiovascular Mortality

Mark É. Czeisler, Josh Leota, Flora Le, Andreas G. Kontopidis et autres

Introduction: Highly irregular sleep-wake timing is prospectively associated with higher all-cause and cardiovascular (CVD) mortality rates. These relationships are hypothesized to reflect harmful effects of inconsistent patterns of exposures (eg, light-dark), behaviors (eg, sleep-wake), and circadian rhythms (ie, intrinsic time-varying physiology). Sex …

Characterizing emotional dynamic trajectories in adolescents: A two‐year longitudinal study with an ecological momentary assessment design

Tingyue Sun, J. Stone, Evangelos Chachos, Anthony J. Hand et autres

Abstract Most research on emotional functioning focuses on the intensity of emotions. Little is known about how current emotion predicts future emotion, or how emotions fluctuate. Understanding how day‐to‐day emotional dynamic indices change over time, especially during adolescence, is important, as this …

Association of Prior COVID-19 Infection with Restorative Sleep Quality Using REST-Q Scores: Findings from the COPE Initiative

M. Ireland, Mark É. Czeisler, Mark Erskine Howard, Rebecca C. Robbins et autres

Objectives: The COVID-19 pandemic has disrupted sleep health globally. However, the relationship between prior SARS-CoV-2 infection and subjective restorative sleep, measured using validated instruments, remains underexplored. This study evaluated the association between prior SARS-CoV-2 infection and restorative sleep quality using Restorative Sleep …

P064 Does napping help or hurt? Investigating individuals attending sleep clinics

A Li, Anne C. Russell, William J. Saunders, Shihai Lu et autres

Abstract Introduction Napping can improve sleepiness, attention and memory in healthy individuals. These effects may not translate to individuals with sleep disorders. This study aims to examine the associations between napping and daytime sleepiness, fatigue, and depressive symptoms in individuals seeking treatment …

P065 Differentiating sleepiness and fatigue in sleep clinic patients

Anne C. Russell, A Li, William J. Saunders, Shihai Lu et autres

Abstract Introduction Sleepiness and fatigue are commonly reported symptoms across a range of sleep disorders. Although they differ in underlying mechanisms and carry different treatment implications, these terms are often used interchangeably, making them challenging to distinguish in clinical practice. This study …

Comparison of Sleep Regularity Index scores calculated by open-source packages and implications for outcomes research: rationale and design of the RIRI statement (Reporting Items for Regularity Indices)

Mark É. Czeisler, Josh Leota, Flora Le, Beaudan Campbell‐Brown et autres

The day-to-day regularity of sleep-wake timing refers to time-varying patterns of behavioral cycles, which co-occur with temporally associated environmental exposures and circadian rhythms. Introduced in 2017, the Sleep Regularity Index (SRI) has enabled rigorous study of the health and performance implications of …
