Abstract Study Objectives To examine the association between sleep duration trajectories over 28 years and measures of cognition, gray matter volume, white microstructure. We hypothesize that consistently meeting guidelines recommend at least 7 hours per night will be associated with better greater volumes, higher fractional anisotropy, lower radial diffusivity values. Methods studied 613 participants (age 42.3 ± 5.03 baseline) who self-reported five time points 1985 2013, had cognitive testing magnetic resonance imaging administered a single timepoint 2012 2016. applied latent class growth analysis to estimate membership into trajectory groups based on time. Analysis volumes was carried out using FSL Voxel-Based-Morphometry microstructure Tract Based Spatial Statistics. assessed group differences in MRI outcomes nonparametric permutation testing. Results Latent identified four groups, an average 5.4 0.2 (5%, N = 29), 6.2 0.3 (37%, 228), 7.0 (45%, 278), 7.9 (13%, 78). No matter, were detected groups. Conclusions Our null findings suggest current may not supported relation patterns function or brain structure.

Abstract The “International Biomarkers Workshop on Wearables in Sleep and Circadian Science” was held at the 2018 SLEEP Meeting of Associated Professional Societies. workshop brought together experts consumer sleep technologies medical devices, circadian physiology, clinical translational research, practice. goals were: (1) characterize term “wearable” for use science identify relevant metrics wearables to measure; (2) assess current science; (3) barriers applying (4) opportunities advance science. For purposes biomarker development fields, included terms “wearables,” “nearables,” “ingestibles.” Given state technology, limited validation wearable devices against gold standard measurements is primary factor limiting large-scale research. As such, committee proposed a set best practices studies guidelines regarding how choose device research use. To complement studies, recommends public data repository data. Finally, scientists must actively engage maintain rigor scientific findings health messages based technology.

A growing body of research has identified circadian-rhythm disruption as a risk factor for metabolic health. However, the underlying biological basis remains complex, and complete molecular mechanisms are unknown. There is emerging evidence from animal human to suggest that expression core circadian genes, such locomotor output cycles kaput gene (CLOCK), brain muscle ARNT-Like 1 (BMAL1), period (PER), cyptochrome (CRY), consequent hundreds genes integral regulation cellular metabolism. These represent potential pathophysiological pathways linking adverse health outcomes, including obesity, syndrome, type 2 diabetes. Here, we aim summarize select in vivo models compare these results with epidemiologic findings advance understanding existing foundational mechanistic links between altered clock contributions health-related pathologies. Findings have important implications treatment, prevention, control pathologies leading causes death disability, diabetes, cardiovascular disease, cancer.

Daylight stems solely from direct, scattered and reflected sunlight, undergoes dynamic changes in irradiance spectral power composition due to latitude, time of day, year the nature physical environment (reflections, buildings vegetation). Humans their ancestors evolved under these natural day/night cycles over millions years. Electric light, a relatively recent invention, interacts competes with light–dark cycle impact human biology. What are consequences living industrialised urban areas much less daylight more use electric throughout day (and at night), on general health quality life? In this workshop report, we have classified key gaps knowledge research into three main groups: (I) uncertainty as quantity needed for “optimal” physiological psychological functioning, (II) lack consensus practical measurement assessment methods tools monitoring real (day) light exposure across multiple scales, (III) insufficient integration exchange bases different disciplines.

Importance

Single self-reported measures of sleep duration are associated with adverse health outcomes; however, long-term patterns and their association cardiovascular events (CVEs) all-cause mortality remain unknown.

Objective

To determine whether trajectories vs single-measure subsequent risk CVEs mortality.

Design, Setting, Participants

The Kailuan study is a prospective, population-based cohort that began in 2006. present included 52 599 Chinese adults without atrial fibrillation, myocardial infarction, stroke, or cancer to 2010. Trajectories from January 1, 2006, December 31, 2010, were identified investigate the 2017. Data analysis was conducted July 1 October 2019.

Exposures

Habitual nocturnal durations collected 2008, for 4 years by latent mixture modeling.

Main Outcomes Measures

All-cause first incident (atrial stroke) 2010 2017 confirmed medical records. Based on baseline over time, categorized (normal stable, normal decreasing, low increasing, stable).

Results

Of (mean [SD] age at baseline, 52.5 [11.8] years), 40 087 (76.2%) male 12 512 (23.8%) female. Four distinct 4-year trajectory identified: stable (range, 7.4 7.5 hours [n = 262]), decreasing decrease 7.0 5.5 8074]), increasing increase 4.9 6.9 3384]), 4.2 879]). During mean (SD) follow-up 6.7 (1.1) years, 2361 individuals died 2406 had CVE. Compared normal-stable pattern adjusting potential confounders, low-increasing increased (hazard ratio [HR], 1.22; 95% CI, 1.04-1.43), normal-decreasing (HR, 1.34; 1.15-1.57), low-stable highest 1.47; 1.05-2.05) death 1.50; 1.07-2.10).

Conclusions Relevance

In this study, lower unstable significantly Longitudinal may assist more precise identification different at-risk groups possible intervention. People reporting consistently sleeping less than 5 per night should be regarded as population higher CVE
